An Introduction to WaveBook and Optional WBKs 2

What are WaveBooks?

WaveBooks are high-speed portable data acquisition devices that can be used in a variety of applications, such as testing engine strain, multi-channel acoustics, mechanical integrity, and vibration/shock/strain. WaveBook features include:

•

Power Options: Power can be supplied from an AC-to-DC adapter, battery, DBK30A rechargeable

battery module, DBK34 or DBK34A uninterruptible power supply modules.

•

Easy Connection to Notebook or Desktop PCs.

•

Analog Input Channels: BNC connectors keep input signals isolated from the chassis and commons.

•

High-Speed Digital Inputs: 8 high-speed digital inputs (16 for WaveBook/516).

•

Digital Signal Processing (DSP): Allows you to define a channel scan-sequence and associated gains

across all channels. Also provides for real-time digital calibration on a per-sample basis.

•

Programmable Scan Sequencing: A 128-location scan sequencer allows you to program the analog

channel scan sequence, the associated unipolar/bipolar A/D range, and the input amplifier gain. WaveBook performs 1 MHz scanning and gain switching over both its built-in and expansion channels.

•

Single, or Multi-Channel Triggering

•

Pre- and Post-Trigger Readings

In addition to the features just listed, the following apply to WaveBook/516:

•

Digital-Pattern Trigger: Trigger occurs when a Digital I/O pattern is equal too, not-equal too, greater

than, or less than a user-defined 16-bit digital pattern. This is useful when trying to capture noise, vibrations or some other physical disturbance that occurs at a particular point in a digitally-sequenced process, such as a relay-logic-control system. Trigger latency of the digital pattern trigger is less than 200 ns for post-trigger acquisitions.

•

Pulse Trigger: Enables triggering and the correlation of lower-speed waveforms with the occurrence of

a user-defined, high-speed pulse.

•

20 kHz Low Pass Filter: Each of the eight channels has its own low pass, anti-alias filter.

•

External Clock Input: The external clock is useful when data collection depends on rotational speed

or axial position. Note that the external clock’s input can be reset to a slower rate.

An Introduction to WaveBook 2-5

How are WaveBook systems powered?

Input voltage to the WaveBook and to the system modules (WBK10 series, WBK14, WBK15, WBK16, and WBK17) must be in the range of 10 to 30 VDC and can come from an appropriate AC-to-DC adapter, or from a battery.

Available AC-to-DC adapters include the TR-40U (supplied), which has an input of 90-264 VAC and a output rating of 2.2 amps @ 15 VDC.

Battery options include the DBK30A, DBK34A, or other 10 to 30 VDC source such as a car battery. The DBK30A provides 14 VDC and when fully-charged has a storage capacity of 3.4 A⋅hr; car batteries have much higher capacities. The basic formula for battery life is:

Runtime (hr) = Battery capacity (A⋅hr) / Current load (A)

System cards (WBK11, WBK12, or WBK13 series) get power from their WaveBook or WBK10/10H/10A expansion module.

Before connecting your system to power, you need to know the power requirements of your specific system. A calculation method, that incorporates the use of worktables, is presented in Chapter 3.

Reference Notes:

•

Chapter 3, System Setup and Power Options, includes examples of power connections for

different WaveBook system scenarios. In these examples the included TR-40U power adapters are used.

•

Chapter 4, WaveBook Operation Reference, includes discussion of power supplies other

than the TR-40U.

Connectors and Cables

To attach a module, connections must be made for power, expansion control, and expansion signals. The following connectors and cables are used.

•

WaveBook POWER IN – connects to a 10 to 30 VDC source.

•

WaveBook POWER OUT – can be connected to the first module’s POWER IN.

•

WaveBook EXPANSION CONTROL – connects to the first module’s EXPANSION CONTROL IN.

•

WaveBook EXPANSION SIGNAL IN – connects to the first module’s EXPANSION SIGNAL OUT.

•

WBK POWER IN – connects to a 10 to 30 VDC source. When in a power daisy-chain, POWER IN connects to the previous WaveBook or WBK module’s POWER OUT.

•

WBK module POWER OUT – can be connected to the next module’s POWER IN, providing the 5 amp current limit will not be exceeded. It may be necessary to use a supplemental power supply. Power requirements and discussed in the following pages.

•

WBK module EXPANSION CONTROL OUT – connects to the next module’s EXPANSION CONTROL IN.

•

WBK module EXPANSION SIGNAL IN – connects to the next module’s EXPANSION SIGNAL OUT.

Prior to connecting your devices to power, calculate your system’s power requirements as discussed in upcoming section of this chapter. Note that three examples of system setups

follow shortly.

Using Shielded BNC Connectors for CE Compliance

Certain Declarations of Conformity identify specific cables and connectors that must be used to meet CE requirements. CE compliant BNC-equipped cards and modules have BNC connectors that are insulated from high voltage sources, including electrostatic discharges (ESD). Such voltages could enter the circuitry through the exposed conductive surface of a connector, possibly resulting in damage to components.

O-Ring

S hielded BNC Connector

Dust Cap

Shielded BNC Connector (with O-Ring) and PVC Dust Cap

To meet CE requi rements, PVC dust caps (p/n CN-96) must cove r all unused BNC connectors. When dust caps are not in place, special coaxial cables (with insulated end-connectors and rubber O-rings) must be used. Note that part number 418-0800 includes two cables (with shielded BNC connectors at each end), and four insulating O-rings.

Properly installed connectors and dust caps ensure the metallic surfaces of the connectors are not exposed to undesirable electrical charges.

CA-115 Power Cables. CA-115 cables are 6 inches long and have two 5-pin male DIN connectors. CA-115s are frequently used to link WaveBook’s POWER OUT connector to a WBK expansion module’s POWER IN connector. CA-115 cables are also used to link an expansion module’s POWER OUT connector to the next daisy-chained module’s POWER IN connector.

CA-115 cables and the device DIN5 connectors (see following figure) are limited to 5 amps at 15 VDC.

Power is supplied to WaveBook modules via a DIN5

type connector located on the rear panel of the device.

Note: An optional CA-116 power cable is available. The CA-116 permits the system to be plugged into

a vehicle cigarette lighter, allowing use of the vehicl e’s battery as a power supply for the WaveBook device.

CA-129 Expansion Control Cables. Control messages are carried by CA-129 expansion-control cables with HD-15, plug and socket connectors. The first expansion unit’s control input is driven from the main unit’s control output. Control inputs of additional WBK modules are driven from the preceding unit’s control output.

CA-150 Expansion Signal Cables. Expansion signals are carried by a CA-150-1 male BNC to male BNC coaxial cable. Each WBK module drives a common parallel analog bus that carries the signals to WaveBook’s Analog-to-Digital Converter (ADC). Each WBK module has EXPANSION SIGNAL IN and EXPANSION SIGNAL OUT connectors for daisy-chaining multiple units.

Calculate system amp load prior to creating a system daisy-chain. Although WaveBook device connectors and CA-115 power cables have 5 amp limits, TR-40Us are limited to

2.2 amps. Tables for determining amp load are provided in the following section,

Calculating System Power.

CA-177 Strain Gage Cablse. CA-177 is an optional set of eight strain-gage cables intended for

use with the eight channels of WBK16. Discussions of the CA-177 strain-gage cable and bridge applications are contained in the WBK16 document module.

Stacking Modules

Using Splice Plates to Stack a WaveBook and two WBK Modules (the handle is optional)

WBK modules are typically shipped with a splice plate kit. Each kit includes two metal plates that screw onto the sides of stacked modules. The plates provide a means of stacking modules to create one rigid assembly. Optional handles can be attached to the splice plates.

Note:

Splice plates will partially block the vents on WBK16s and WaveBook/516s when stacked. This partial blocking of vents does not jeopardize the cooling process.

Connecting Encoders to WBK17

Encoders can be used in a WaveBook system, providing the system contains at least one WBK17 module. For information regarding encoders and the necessary connections, refer to the WBK17 Document Module.

Connecting the System to Power

Calculating the System Power Requirement

An incorrect use of power can damage equipment or degrade performance. Prior to connecting your devices to power, calculate your system’s power requirements.

Do not daisy-chain the power connections of more than three WBK10 series module units. Daisy-chaining a power connection to a fourth module will exceed the power connector’s 5 amp current limit.

It is important to supply your system with adequate, reliable power. For this reason, you need to know your system’s power requirement. Computing power use is also important when using batteries to power modules, as you will need to know a safe runtime before recharging is required.

&$87,21

The following statements relate to system power. They should be reviewed before proceeding.

•

Higher voltages draw fewer Amps for the same power. Remember: Watts = voltage x current (W = E*I).

•

The TR-40U power adapter provides power that is sufficient for the WaveBooks and WaveBook modules. You do not need to make power requirement calculations unless you intend daisy-chaining units, or yo u ha ve a critical battery runtime.

•

Do not overload your power supplies. TR-40U power adapters are limited to

2.2 amps. However, you can use more than one TR-40U, as indicated in one of the upcoming daisy-chain examples.

•

Current drawn from other sources, such as car batteries, can be estimated from the following WaveBook Product Current Requirements table.

Use the current requirements and worksheet tables to calculate your system’s total power requirement. Take the appropriate amperage values from the first table to fill in the second table; then perform the indicated multiplication and addition operations to calculate the amperage for all units in your system.

It is important to supply your system with adequate, reliable power. For this reason, you need to know your system’s power requirement. Knowing the power requirement is also important when using batteries to power modules, as you should know a safe runtime, i.e., how long you can run the system be fore recharging is required.

Input voltage to the WaveBook/512, WaveBook/516 and to the system modules (WBK10 series, WBK14, WBK15, WBK16, and WBK17) must be in the range of 10 to 30 VDC and can come from an AC-to-DC adapter or from another source, such as a battery. System cards (WBK11, WBK12, or WBK13) get power from their host WaveBook or WBK10 series expansion module.

Available AC-to-DC adapters include the TR-40U (supplied), which has an input of 90-264 VAC and an output of 2.2 amps @ 15 VDC.

3-10 System Setup and Power Options

05-15-01

WaveBook User’s Manual

Battery options include the DBK30A, DBK34A, and other 10 to 30 VDC sources, such as car batteries. The DBK30A provides 14 VDC and when fully-charged has a storage capacity of 3.4 A⋅hr; car batteries have much higher capacities. The basic formula for battery life is:

Runtime (hr) = Battery capacity (A⋅hr) / Current load (A)

Battery life and performance depend on various factors including battery type, condition, charge level, and ambient temperature. Be sure you consider these factors, especially when runtime is a critical.

The power adapter (included) converts AC power to 24 VDC for charging DBK30A’s two battery packs. Automatic charging circuits recharge the internal batteries quickly and safely. The charged battery runtime depends on the current load and mode of operation.

An internal slide switch (SW2) determines the unit’s mode. The two modes are:

•

14 VDC Mode (default)

•

28 VDC Mode

You should check the power requirements of each component in your system, and then verify that the power source can provide sufficient power to meet your runtime requirements.

Fully charge DBK30A’s batteries before use.

System Setup and Power Options 3-13

14 VDC Mode (default)

This mode provides 14 VDC for 3.4 A-hr. The typical battery runtime is from 3 to 6 hours depending on the load. Unless 28 VDC is required, the 14 VDC mode should be used in WaveBook and WBK applications,

28 VDC Mode

The 28 VDC mode actually provides both 14 VDC and 28 VDC. Loop currents for two-wire, 4-20 mA transmitters (1.7 A-hr) require 28 VDC. The battery run-time ranges from 1 to 6 hours, depending on system configuration. I n t his mode, 14 VDC i s used for unregulated bridge excitation (fo r bridgeconfigured sensors, such as load cells), and power to WBK expansion products.

Hardware Setup

Configuration

The only configuration option is the choice of modes (14 VDC, or 28 VDC). If you do not need 28 V, leave SW2 in the default position.

Internal switch SW2 is located on the printed circuit board, near the front center of the unit. To change or verify the mode:

Unless you need 28 V, leave the unit in the 14 VDC mode.

Use of the 28 VDC mode results in a lower runtime, as only one battery pack can be used for 14 VDC. When in the 14 VDC mode, both packs are used in parallel, resulting in a longer runtime for the same application.

Unless you need 28 V, leave the unit in the 14 VDC mode.

If you are using a pre-owned DBK30A, or are unsure of the mode selected, use the following steps to check SW2’s position. Note that new units are always shipped with SW2 selected to the 14 VDC mode.

1. Remove DBK30A’s cover by removing one screw and sliding the cover forward until it separates from the module.

2. Look near the front center of the circuit board and locate slide switch SW2.

3. Check SW2’s selection. The silkscreen indicates the 14 and 28 VDC positions.

Another use of the 28 VDC mode is to provide excitation for bridge-type sensors, such as load cells (strain gages) and other devices that may be attached to 5B modules inside a WBK15.

Excitation voltage from DBK30A is not regulated by the unit, and must therefore be regulated externally. For most load cells, excitation voltage should be regulated to 10 V.

Charging.

To charge the DBK30A batteries:

1. Connect the adapter to DBK30A’s POWER IN connector.

2. Plug the adapter into the AC power receptacle.

Note that the charge cycle will begin automatically whenever AC power is applied after an interruption. The charge cycle will automatically end when the batteries are fully charged.

Charging DBK30A’s Batteries

3. To manually initiate a charge cycle, press the START CHARGE momentary rocker-arm switch.

Note that subsequent charge cycles applied to a fully-charged DBK30A will have no ill effect. The module will sense the fully-charged status and revert to the trickle-charge state within a few minutes.

Periodically, fully discharge the DBK30A to inhibit “lazy chemistry” (memory) in the nickel-cadmium cells. To manually discharge a battery pack, connect a WaveBook to the pack and leave it powered-on until the indicator lights go out.

Use While Charging. Both operating modes are capable of powering the WaveBook products while being charged; however, the charging current is reduced, and charging time is increased. If AC power is interrupted, a new charge cycle will begin automatically when AC power returns.

&$87,21

Even with the AC adapter, the batteries will eventually discharge under a WaveBook operating load. Charging DOES NOT BEGIN AUTOMATICALLY (except on powerup). You must manually initiate the next charge cycle. Do not expect a WaveBook powered by a DBK30A to operate a s an uninterrupta ble po wer supply.

DBK34A Vehicle UPS/Battery Module

DBK34A is similar to DBK34 in appearance and operation; but there are differences. Before proceeding with this section, verify that your device is a DBK34A. If your device does not have the “A” suffix, use the preceding section regarding the DBK34 Vehicle UPS Module instead of this section.

DBK34A Front Panel

The DBK34A can power a data acquisition system in portable or in-vehicle UPS applications (both 12 V and 24 V systems). Power storage capacity is 5 A-hr @ 12 VDC or 2.5 A-hr @ 24 VDC.

For reliable data acquisition in a vehicle, the DBK34A provides clean and consistent operating power:

•

Prior to engine/generator start

•

During engine start-up (battery sag due to the high-current demand of starter motor and solenoid)

•

After engine turn off.

•

Before and after connection to the vehicle

The DBK34A contains two sealed-lead rechargeable batteries (Gel-Packs), associated charging circuits and current indicators. Typically, these batteries can last more than 500 full cycles and up to 10 years standby lifetime at room temperature. Recharging is fast, and extreme temperature performance is good. The DBK34A can be used with the LogBook, DaqBook, WaveBook, and related DBKs and WBKs. The unit’s rugged metal package has a compatible 8×11” footprint for convenient stacking with Velcro tabs and optional splice plates and handles for carrying.

Main and auxiliary power input comes from 12 or 24 VDC via a terminal block on the unit’s front panel (12 or 24 V modes are set by front-panel jumpers). Automatic, temperature-compensated charging circuits recharge the internal batteries quickly and safely. For trouble-free operation, you must fully charge the batteries before use. The charged battery runtime will depend on the load and mode of operation.

During use of the internal batteries, the Charging LED blinks and a beeper sounds when battery life is almost exhausted. Within a few minutes, internal cutoff circuits disconnect the load from the batteries to prevent the possibility of deep-cycle damage.

Note: Current protection is provided by four fuses. Two 7.5A fuses for the unit’s internal batteries,

one 7.5 A fuse for an auxiliary (external) battery, and a 15 A fuse for the power input.

You can use a CA-172 cable to connect a vehicle battery (via a cigarette lighter) to the DBK34A terminal board. The cable is six feet long, contains a cigarette lighter adapter at one end, and stripped leads (for terminal connection) at the other.

For trouble-free operation, fully charge the batteries before use. Charged battery runtime depends on the load and on the mode of operation.

Runtime. Approximate runtime under various loads can be computed from the storage capacity (5 A-hr in 12 V mode; 2.5 A-hr in 24 V mode) and the load (main unit and other DBKs).

The following Load Wattage vs. Hours graph is for a typical new battery that is fully charged.

Charging: In general, lead-acid batteries [and related Gel-Packs] require charging at 120% of drain energy (e.g., the 5 A-hr DBK34A requires a charge equal to or greater than 6 A-hr). Charging times vary; but 4 to 5 hours at 14 V is typical for a completely discharged battery; after which, charging may continue indefinitely.

Note that 16 to 18 VDC at the power input is required for optimal charging.

Voltage applied to a DBK34A must not exceed 30 VDC.

Environmental Concerns

DBK34A Gel-Pack batteries contain toxic materials (Pb and H2SO4). At the end of the battery life cycle (typically after 5 to 10 years of use), the Gel-Packs must be recycled or properly disposed of.

Each channel has input protection and connects t o J 10 via its own BNC connector. Channel 1 is the only channel that

connects to the Analog Trigger Detector.

An optional WBK11, WBK12, or WBK13 series board can be used in plac e of t he on-board PGA c irc uit. Prior to

installing an option board, jumpers on J10 and J11 m us t be rem oved to disengage the PGA circuitry.

In regard to WaveBook/512 and WaveBook/512H, each of the 8 pairs of differential signals (one per BNC connector) is buffered and then switched by the channel-selection multiplexer. The selected differential pair is then converted to a single-ended signal by the programmable gain amplifier (PGA) and level-shifted to locate the desired range (within the A/D converter's fixed input range). Two offset settings are available, unipolar and bipolar. Unipolar offset is used for sampling signals that are always positive. Bipolar offset is used for signals that may be positive or negative. For example, when set for unipolar at a gain of ×5, the input span is 2 volts and the amplified signal is offset so that input voltages from 0 to +2 volts can be digitized. When set for bipolar operation, the offset is adjusted so that input voltages from -1.0 to +1.0 volts can be digitized. The signal is then switched over to the A/D converter and digitized to 12 bits in 1 µs. Note that the A/D converter's input can be switched to the expansion signal input, allowing the device to read one of 64 possible expansion channels (supplied by up to eight WBK10 expansion chassis). A digital signal processor (DSP) processes the digitized value and corrects the value for gain and offset errors. The DSP places the corrected result into the FIFO data buffer that holds the samples until the PC reads the data. If the sample is used for triggering, the DSP determines if a valid trigger event has occurred.

WaveBook includes low-latency analog or TTL-level triggering. The analog trigger detector examines channel 1 to determine if a trigger has occurred. The selected low-latency trigger is presented to the controland-timing circuit that starts the acquisition after the trigger. The TTL trigger is taken directly from the digital I/O port.

4-2 WaveBook Operation Reference

06-08-01

WaveBook User’s Manual

For every sample, the DSP reads from a scan sequence table and accordingly programs the control-andtiming circuit for the next sample. The circuit waits precisely until the start of the next sample and then selects the: input channel, PGA gain, level-shifter offset, and A/D input source. It also conveys this information to any attached expansion units and precisely controls the A/D conversion timing.

The EEPROM holds the calibration information needed for real-time sample correction. The digital I/O port is read and written by the Digital Signal Processor to transfer bytes of digital data.

It may be used as a simple 8-bit input port or as a 32-address byte-wide I/O port. The high-speed EPP/ECP interface circuit connects the WaveBook and any attached printer to the PC via

standard DB-25 connectors. When the WaveBook is active, the interface holds the printer in a stable state; and when the WaveBook is inactive, the interface connects the PC to the printer.

Pin-header J101 allows the addition of the WBK30 memory option. The WBK30 is detailed in the WBK30 Document Module. Pin-headers J10 and J11 allow the addition of the optional WBK11, WBK12, or WBK13. These cards can also be added toWBK10/10H/10A expansion modules.

WaveBook/516, t hes e boards are not “Plug-and-play.” They are only to be installed at t he f ac t ory.

In regard to WaveBook/516, each of the 8 pairs of differential signals (one per BNC connector) is buffered and applied to a differential amplifier. The output of each differential amplifier is applied to a 5 pole, low pass filter. The filter and channel-selection multiplexer then switches the non-filtered and filtered signals to a programmable gain amplifier (PGA). The amplified signal is level-shifted to locate the desired range (within the A/D converter's fixed input range). Two offset settings are available, unipolar and bipolar. Unipolar offset is used for sampling signals that are always positive. Bipolar offset is used for signals that may be positive or negative. For example, when set for unipolar at a gain of ×5, the input span is 2 volts and the amplified signal is offset so that input voltages from 0 to +2 volts can be digitized. When set for bipolar operation, the offset is adjusted so that input voltages from -1.0 to +1.0 volts can be digitized.

The signal is switched over to the A/D converter and digitized to 16 bits in 1 µs. Note that the A/D converter's input can be switched to the expansion signal input, allowing the device to read one of 64 possible expansion channels (supplied by up to eight WBK10 expansion chassis). The digital signal processor (DSP) processes the digitized value and corrects the value for gain and offset errors.

The selected low-latency trigger is presented to the control and timing circuit that starts the acquisition after the trigger. The TTL trigger is taken directly from the digital I/O port.

Every sample time, the DSP reads from the scan sequence table and accordingly programs the control and timing circuit for the next sample. The control and timing circuit waits precisely until the start of the next sample, then selects: input channel, PGA gain, level-shifter offset, and A/D input source. It conveys this information to any attached expansion units and precisely controls the A/D conversion timing.

The EEPROM holds the calibration information needed for real-time sample correction. The digital I/O port is read and written by the Digital Signal Processor to transfer bytes of digital data.

It may be used as a simple 8-bit input port or as a 32-address byte-wide I/O port. The high-speed EPP/ECP interface circuit connects the WaveBook and any attached printer to the PC via

standard DB-25 connectors. When the WaveBook is active, the interface holds the printer in a stable state; and when the WaveBook is inactive, the interface connects the PC to the printer.

Pin-header J101 allows the addition of the WBK30 memory option. The WBK30 is discussed later in this chapter. Pin-headers J10 and J11 allow the addition of the optional WBK11, WBK12, or WBK13. These cards can also be added toWBK10/10H/10A expansion modules.

WaveBook/516 Fan

WaveBook/516 components are air-cooled and cooling to ambient occurs as long as the surrounding environment is cooler than the unit. When the unit becomes too warm for ambient cooling, a te mperature sensor signals the fan to run.

Fan speed varies according to WaveBook/516’s internal temperature. In cooler temperatures the fan operates at lower speeds, thus reducing audible noise.

To allow for sufficient cooling, it is important to keep the fan and vents free of obstruction. Note: The partial blocking of vents by splice plates (in stacked assemblies) does not

jeopardize unit cooling.

Triggers

External signals can be used to start or synchronize the data acquisition process. Both WaveBook/512 and WaveBook/516 series support the following trigger sources:

•

Software Trigger. This trigger event is generated by a software command from the PC without waiting for an external event. This feature may be used to begin a data acquisition

immediately or to force an acquisition to occur if the expected trigger did not occur.

•

Digital Trigger. Digital (or TTL-level) triggering (either rising- or falling-edge input) is performed by digital logic connected to the digital expansion connector.

•

Single-Channel Trigger. Single-Channel (or Channel 1 Analog) triggering (rising or falling signal level) is performed by comparator-based analog hardware connected directly to analog input channel 1.

•

Multi-Channel Trigger. Here, the trigger event is a combination of measured channel values. WaveBook's Digital Signal Processor (DSP) performs multi-channel triggering. The

DSP samples the specified channels; if programmable conditions are met, a trigger is generated. Multi-channel triggering examines digitized data, and the trigger latencies are much greater.

WaveBook/516 supports the four trigger sources identified above, plus two more: Digital-Pattern Trigger and Pulse Trigger.

•

Digital-Pattern Trigger: WaveBook/516 supports a digital-pattern trigger. This expanded digital-trigger capability allows data collection to start when a user-defined 16-bit digital pattern is matched on the digital I/O connector. This feature is useful when trying to capture noise, vibrations or some other physical disturbance; such as those that can occur in a programmed logic controller’s digitally sequenced process.

•

Pulse Trigger: WaveBook/516’s pulse trigger is a high-bandwidth input that enables triggering and the correlation of lower-speed waveforms with the occurrence of a highspeed pulse. With pulse trigger, the user defines pulse amplitude between ±5 V and pulse

width from 100 ns to 800 ms.

More detailed information regarding triggers follows.

Digital Trigger & Single-Channel Trigger

The input of the digital (TTL) trigger and the output of the single-channel signal-comparator are each connected directly to hardware circuits to provide low-latency triggering. WaveBook can respond to a TTL or analog trigger with a jitter (or uncertainty in latency) of no more than 100 nanoseconds (ns).

•

If not collecting pre-trigger data, WaveBook responds to the trigger with a latency of less than

200 ns for TTL and 300 ns for analog.

•

If collecting pre-trigger data, then triggers are not acted upon until the end of the current pre-

trigger scan. This increases the trigger latency and jitter, but preserves the specified scan rates.

When using the single-channel trigger, the Channel 1 analog input signal is compared with a programmable voltage level to generate an internal TTL signal that is true if the analog input is greater than the programmable voltage level (false if less).

When the digital trigger is used, then the TTL trigger signal from the digital I/O connector is used directly. The resulting TTL signal is examined under program control for either a false-to-true (rising edge) or trueto-false (falling edge) transition which, when it occurs, is the trigger event.

If the system is ready for a trigger, then the trigger event will be acted upon. If the system is not ready (due to incomplete configuration or because it is still finishing the previous trigger's action), the trigger will be ignored. No indication of an ignored trigger is given.

The low-latency analog trigger compares the analog signal with a programmable voltage source. The effective range of this voltage source depends on whether or not the WBK11 SSH option is installed.

•

Without SSH, the trigger threshold is settable from -5.0 to +9.996 volts with 12-bit (WaveBook/512) resolution, regardless of any channel's gain settings. This gives better than 1% resolution at even the smallest input ranges (such as 0-1 or ±0.5 volts).

•

With SSH, the single-channel (Channel 1 analog) signal is first amplified by the SSH programmable gain amplifier before being compared with the programmable voltage. This allows precise trigger-level adjustment, even at high gain. The analog-trigger comparator threshold-voltage range and resolution (with SSH) are shown in the following table.

Hysteresis

The analog trigger circuit has hysteresis that reduces the occurrence of retriggering due to input noise. The hysteresis level without SSH is 25 mV; the hysteresis with SSH is 1/600 of the comparator range. The next figure shows the hysteresis effect for a ri sing-edge trigger.

Trigger

No Trigger

Trigger

Trigger Level

Hysteresis Range

A trigger will occur when the analog input rises above the trigger level—but only after the input level has been below the hysteresis range. If the level momentarily drops just below the trigger level (perhaps due to noise) and then rises above it again, no extra triggers will be generated—the signal did not drop below the hysteresis range. After the level drops below hysteresis, it can then again produce a trigger by rising above the trigger level.

Multi-Channel Trigger

When the small hardware-limited latencies of the digital (TTL) and single-channel (Channel 1 analog) triggers are not required, the DSP chip may be used to examine the samples from one or more channels and to decide if they constitute a pre-defined trigger condition.

The DSP can sample up to 72 input channels and examine each one to determine if it meets programmed levels for a valid trigger. This multi-channel triggering is a two-step process:

1. The DSP examines each of its specified input signals to determine trigger validity.

2. After all of the channels have been examined, the DSP logically combines the individual triggers to generate the actual trigger. The DSP may be programmed to generate a trigger if trigger is valid (OR) or if (AND). See figure.

Multi-Channel Trigger Types

The first step in multi-channel triggering is to examine the input signals. To determine trigger validity, WaveBook can examine each input signal in 1 of 8 ways.

Note: Each trigger type is a

elements: slope, duration, and initialization.

Slope (above/rising or below/falling) sets whether the trigger is valid when the signal is:

•

Above the trigger level (rising)

•

Below the trigger level (falling).

Duration (instantaneous or latched) specifies the action to take if the signal level becomes invalid after it has been valid:

•

Instantaneous triggers become invalid as soon as the signal does; they are used to trigger on the coincidence of signals, when two or more signals are simultaneously valid.

•

Latched triggers remain valid until the acquisition is complete; they are used to trigger on the

occurrence of signals, when two or more signals have already become valid. The trigger duration only makes a difference in multi-channel "AND" triggering. In multi-channel "OR" triggering, WaveBook will be triggered as soon as any channel becomes valid; what happens when a channel becomes invalid does not matter. In contrast, "AND" triggering waits for all of the triggers to be valid; and so, latching can be important for rapidly changing signals.

Initialization (level or edge) specifies the sequence necessary for a signal to be a valid trigger:

•

Level triggers become valid as soon as they reach or exceed the trigger level, even if they are already past the trigger level when the acquisition is started.

•

Edge triggers first wait until the signal level is invalid. Then they wait for the signal to reach the trigger level before becoming valid. Thus, level triggers look for a signal level, whenever it occurs; and edge triggers look for a rising or falling transition that reaches the trigger level.

Examination of the input signals compares two specified signal levels: (a) The trigger level determines when the input channel is a valid trigger, and (b) the hysteresis is the amount by which the channel must differ from the trigger level for the channel to become invalid.

This trigger is valid whenever the signal level is above the trigger level and stays valid until the signal level goes below the hysteresis range. In the figure, the channel trigger is valid during the 2 shaded intervals. Whether this condition triggers WaveBook or not, depends on the type of multi-channel triggering ("AND" or "OR") and on the state of other trigger channels. With "OR" multi-channel triggering, WaveBook will trigger when the signal first rises above the trigger level—if ready for a new trigger, WaveBook will also trigger the second time the signal rises above the trigger level. With "AND" multi-level triggering, WaveBook will not trigger until every specified trigger channel is valid. If all other trigger channels are valid, WaveBook will trigger when the signal reaches the shaded region; but if some channels are not valid, this channel will have no effect.

Trigger Level

The channel becomes valid when the signal level rises above the trigger level and stays valid until the acquisition is complete and WaveBook is re-armed (the reverse of above-level-with-latch triggering). Latched triggers are often used in multi-channel "AND" triggering, where WaveBook will not trigger until all trigger channels are valid. After a latched trigger becomes valid, it stays valid (waiting for the other triggers to become valid) until WaveBook is triggered and the acquisition completes. If the trigger is nonlatched instead of latched, the channel may not stay valid and WaveBook will not trigger until the channel becomes valid again and all channels simultaneously reach their trigger levels. In other words, latched

triggering is used to trigger after something has occurred, but non-latched triggering is used only during the simultaneous occurrence of desired signal levels. It is possible to combine different trigger types in a

single multi-channel trigger. For example, WaveBook could trigger when channel 3 is below 0.9 volts after channel 2 has gone above -1.3 volts (by configuring channel 3 for below-level triggering and channe l 2 for above-level-with-latch triggering).

Rising-Edge Trigger

Rising slope

Instantaneous duration

Edge initialization

This trigger becomes valid after the signal level has been below the hysteresis range and then goes above the trigger level. This trigger becomes invalid when the signal level goes below the hysteresis range. Unlike above-level triggering, the channel cannot become valid until the signal level first goes below the hysteresis range. This prevents the false triggering that would occur if the signal were above the trigger level at the start of the acquisition.

Trigger Latency & Jitter

Trigger latency and jitter depend on the trigger source and the acquisition mode:

•

Trigger latency is the duration between the valid trigger and the start of the acquisition.

•

Trigger jitter is the variation of the latency, how much time the latency can vary from trigger to trigger.

As discussed, WaveBook has post-trigger and pre/post-trigger acquisition modes. Post-trigger modes (N-shot, N-shot with re-arm, and infinite-post-trigger) collect scans only after the trigger has occurred. They are different from the pre/post-trigger mode that collects scans both before and after the trigger. This difference affects the trigger latency and jitter.

In a post-trigger mode, WaveBook is not scanning while waiting for the trigger. Thus, it is free to respond to the trigger as soon as it occurs. This minimizes the trigger latency and jitter.

In the pre/post-trigger mode, pre-trigger data is being collected while WaveBook waits for the trigger, and WaveBook will not respond to a trigger until the current scan is complete. The pre-trigger scan period separates the first scan after the t rigger from the last sc an before the trigger. All the scans (up through the one immediately following the trigger) are collected at the pre-trigger rate; and all subsequent scans are collected at the post-trigger rate. This preserves the integrity of the acquisition timebase as shown in the figure below:

The time needed to complete the final pre-trigger scan is part of the trigger latency; and so, in the pre/posttrigger mode, the trigger latency may be greatly increased.

Not only do the trigger latency and jitter depend on the pre- vs post-trigger type of acquisition, they also depend on the trigger source: Software, digital (TTL), single-channel (Channel 1 analog), or multi-channel. The following table gives the trigger latency and jitter for each of the different trigger sources and acquisition modes:

Pulse Trigger

In addition to the standard “single-channel” trigger-on-level functions, the WaveBook/516 system supports pulse trigger. The connection is made via BNC connector located next to the Channel 8 BNC. With pulse trigger, you can define both the amplitude and the duration of the pulse that will be used to trigger the acquisition. Pulse trigger can be used to detect spurious transients that can be missed by simple level triggers.

(WaveBook/516 Series Only)

Pulse Tri gger allows the use of a hi ghbandwidth input for triggering, and the correlation of lower-speed waveforms with the occurrence of a high-speed pulse. You can set a pulse amplitude between ±5 V and a pulse width in the range of 100 ns and 800 ms.

This option allows you to trigger on analog level “pulses” on either the Channel 1 input or the Pulse Trigger input. This trigger type is similar to the Channel 1 Analog trigger but places an additional time-based condition on the signal. Depending on whether the pulse width is set as a minimum or a maximum, the signal either must or must not cross the threshold again within the given amount of time.

4-14 WaveBook Operation Reference

06-08-01

Pulse Trigger Selected

WaveBook User’s Manual

The red horizontal line (Threshold) and blue vertical lines (defining maximum width) will vary according to the parameter settings. You can specify either one or two thresholds for the level and width settings. The number of labels matches the number of thresholds and the placement follows the polarity.

•

For positive polarity, the text is “Rise Above... Stay Below.”

•

For negative polarity, the text is “Fall Below and Stay Above.”

Note: When used as a maximum, the pulse width setting can capture signal pulses.

As a minimum, it is useful for ignoring pul s es.

Digital-Pattern Trigger

This type of trigger is useful when trying to capt ure noise, vibrations or some other physical disturbance that occurs at a particular point in a digitally-sequenced process, such as a relay-logic-control system.

When “Digital Pattern” is selected as the Triggering Type, the 16-bit pattern extension appears (as indicated in the following figure). The Condition box allows the following choices:

Equal To (=) / Not Equal To (< >) – T hese options treat each digital line as a separate input to be compared to logical 1 or 0. Selecting “Equal To” triggers only on the exact pattern of 1’s and 0’s selected., while “Not Equal” triggers on all others. You can also set any of the inputs to “don’t care” (X), which excludes it from the comparison.

Greater Than (>) / Less Than (<) – These options interpret the digital inputs as a single 16-bit value and allow a threshold trigger.

The Internal and External buttons located in the rate section of the screen (previous and following

WaveBook/516 is capable of receiving external clock input. The external clock is useful when data collection depends on rotational speed or axial position. By synchronizing the system with an external event for correlation of data, you can collect event-dependent data instead of time-dependent data.

WaveBook/516 can receive an external clock input through pin 20 of the DB25 connector labele d DIGITAL I/O, EXTERNAL CLOCK, TTL TRIGGER. This enables data scanning to be correlated with an

external pulse train. To enable the external clock, select “External” for the Scanning Rate in the Acquisition Configuration Dialog Box (see following screen shot). When the external clock is enabled,

WaveBook/516 begins a scan only after a rising edge on the TTL level occurs. Optionally, the external clock may be divided [by a factor of 1 to 255]. This “pre-scaling” allows the user to select a reduced scan rate.

When enabled, the low (CtrLo), then high (CtrHi) words of the counter will be configured in each scan. Note that the spreadsheet’s view a predefined period in units of seconds, ms, or µsec.

WaveView can be configured to read only the low word of the counter data (CtrLo:“On,” CtrHi: “Off”). This decreases the minimum scan period by 1 usec. This LoCtr only option can be used only when the external clock frequency is greater than 305 Hz (20,000,000 MHz / 65536]. Note that WaveView does not enforce this.

You can use WaveView to select a channel’s range in one of two ways. (1) Click in a channel’s Range cell, then select the desired range from the “Select Range” pull-down list. (2) Continue to double-click in the applicable channel’s Range cell to cycle through the a vailable ranges. Stop double-clicking when the desired range is indicated.

Selecting a Channel’s Units

You can use WaveView to select a channel’s units in one of two ways.

(1) Click in a channel’s Units cell, then select the desired units from the “Select Units” pull-down

list.

(2) Double-click in a channel’s Units cell to cycle through the uni ts. Note that after the mX+b

dialog box appears you must click “OK” to continue cycling.

Note: You can use the mX+b equation to adjust a channel’s scale and offset. You can enter user-defined

units from the mX+b dialog box. An example of using mx + b is provided below, and on the following page.

After completing channel configuration, you can select the Acquisition Configuration option from WaveView’s View menu or tool bar. The figure to the right represents the Acquisition Configuration dialog box. The parameters shown are a result of the values entered below the figure.

Clicking the Close button sets the acquisition parameters as the active parameters.

Engineering Units Conversion Using mx + b

Most of our data acquisition products allow the user to convert a raw signal input (for example, one that is in volts) to a value that is in engineering units (for example, pressure in psi). The products accomplish this by allowing the user to enter scale and offset numbers for each input channel, using the software associated with the product. Then the software uses these numbers to convert the raw signals into engineering units using the following “mx + b” equati on:

Engineering Units = m(Raw Signal) + b (1)

The user must, however, determine the proper values of scale (m) and offset (b) for the application in question. To do the calculation, the user needs to identify two known values: (1) the raw signal values, and (2) the engineering units that correspond to the raw signal values. After this, the scale and offset parameters can be calculated by solving two equa t ions for the two unknowns. This method is made clea r by the following example.

Example

An engineer has a pressure transducer that produces a voltage output of 10.5 volts when the measured pressure is 3200 psi. The same transducer produces an output of 0.5 volt when the pressure is 0 psi. Knowing these facts, m and b are calculated as follows.

A - Write a pair of equations, representing the two known points:

3200 = m(10.5) + b (2)

0 = m(0.5) + b (3)

B - Solve for m by first subtracting each element in equation (3) from equation (2):

3200 - 0 = m(10.5 – 0.5) + (b - b) (4)

Simplifying gives you:

This means:

C - Substitute the value for m into equation (3) to determine the value for b:

Now it is possible to rewrite the general equation (1) using the specific values for m and b that we just determined:

3200 = m(10) (5)

m = 320 (6)

0 = 320 (0.5) + b (7)

b = - 160 (8)

Engineering Units = 320(Raw Signal) - 160 (9)

The user can then enter the values of m and b into the appropriate location using the facilities provided by compatible data acquisition software, for example: WaveView, DaqView, Personal DaqView, LogView, and TempView. The software uses equation (9) to calculate signal values in engineering units from that point on.

Electrostatic Discharge (ESD), Handling Notice

The discharge of static electricity can damage some electronic components. Semiconductor devices are especially susceptible to ESD damage. You should always handle components carefully, and you should never touch co nnector pins or circuit components unless you are following ESD guidelines in an appropriate ESD-controlled area. Such guidelines include the use of properly grounded mats and wrist straps, ESD bags and cartons, and related procedures.

Product Care

WaveBooks and WBK options are essentially maintenance free and require a minimal amount of care. They should be treated much like other high-tech equipment. In general:

•

A “common-sense” approach to handling WaveBook products will go a long way in protecting them from inadvertent damage.

Note that you can use lint-free rags and Isopropyl Alcohol (Rubbing Alcohol) to clean the outer plate surfaces of WaveBook and WBK modules.

Keep them clear of harsh chemicals and abrasive elements. Avoid exposing the products to extreme heat, for example, avoid setting up a WaveBook system near

a boiler or furnace.

Avoid extreme shock and vibration. Avoid subjecting the units to liquids and extremely fine air particulate, such as silica dust. Never touch circuit boards without proper ESD (Electrostatic Discharge) measures in place.

Connection Problems

Make sure the parallel port is operable and capable of generating interrupts. The parallel port, to which the WaveBook is to be connected, must be properly configured in order for the device to operate correctly.

Each device must be configured using the Daq*Configuration Applet [located in the Windows’ Control Panel]. If a device is not configured correctly it will not be accessible from an application.

If communications cannot be established with the WaveBook or, if trying to connect causes the system to hang or crash, try the following:

•

Verify that the MODULE POWER switch is set to ON and that the MODULES ON indicator is lit.

•

Check to make sure that the Notebook PC communication cable is properly connected to the WaveBook’s DB25 connector labeled “TO COMPUTER PARALLEL PORT.”

•

Check that the desired LPT port is properly configured and the base address and interrupt are recognized by the operating system.

•

Check the BIOS settings for the LPT port. Make sure that the BIOS LPT protocol settings are compatible with the settings selected for the LPT port. "Compatibility mode" is recommended.

•

Run the Daq Configuration applet from the Windows Control Panel. Make sure the device is configured to the appropriate LPT port with the appropriate protocol. Run the device test and if it fails try other protocols for the device. Be sure to click on the test.

32-Bit WaveView Issues

•

The 32-bit version of WaveView uses a default scheme whereby buffer allocation is dynamic depending on the amount of physical memory on the computer. An advanced feature is available in this release to let the user have more control of the buffer allocation. Generally, better performance will be obtained by increasing the amount of RAM. This allows fewer swaps of VM (virtual memory) to the drive thus allowing the possibility of greater performance. However, VM management during acquisition configuration for large acquisitions may cause WaveView to take a significant amount of time to configure the acquisition.

•

Acquisition parameters can no longer be changed during an active acquisition. The 16-bit version of WaveView allowed the changing of configuration parameters during an acquisition.

•

Scope scale changes do not become effective until the focus changes. This is best accomplished by hitting

<Enter>

•

International settings are supported, but some text boxes may not completely show the comma when it is used as the decimal place holder.

•

The Scope Mode’s print resolution is determined by the host computer’s video driver. Some graphics drivers may require adjustment of the resolution and/or color palette for proper print operation. Fo r some printers, better output is attained by changing the printer's dithering setting to "None".

•

Text boxes for the filter settings may not display the proper setting if the number entered must be rounded to the nearest filter setting. This is a problem only with the number displayed and does not affect the actual filter setting passed down to the driver.

•

Conversion to Snap Master format from the menu option is not supported. Snap Master format conversion does work properly when done as part of a direct-to-disk acquisition.

Windows 95/98/Me Issues

This section only applies to Windows 95/98/Me installations.

Resource Settings

If WaveBook fails to communicate or has problems transferring data, there may be a resource conflict with other devices within the system. Take the following steps if this appears to be the case.

ECP (Enhanced Capabilities Port) Setup

If the WaveBook fails to communicate in ECP mode, make certain that the WaveBook hardware is actually capable of ECP communications. This can be done as follows:

1. Locate the LPT port communications chip on the main board, near the connector that the parallel cable connects to. The chip is relatively large and is stamped “262-0301” or “262-0301, rev B.” A 262-0301 rev. B" chip supports ECP, the earlier rev does not. Contact the factory in regard to upgrading. Note that most units purchased before July 2000 do not have ECP support.

2. Verify the parallel port hardware is in ECP mode. For ports built into the computer’s motherboard, the port i s usually configured using the computer’s BIOS setup utility (accessible during computer start up). See your computer's specific documentation regarding accessing the BIOS setup utility and configuring peripherals.

3. Verify the parallel port is configured [in the Windows Control Panel] as an "ECP parallel port" and not "Parallel port."

Windows95/98/Me users can follow the steps below in regard to locating parallel port resource information.

Parallel Port Setup (general)

If WaveBook fails to communicate or has problems transferring data there may be a problem with the way the parallel port is configured. If this appears to be the case take the following steps:

1. Ensure that any hardware settings on the parallel port are configured properly. If unsure of proper configuration, refer to the parallel port manufacturer's documentation. If this fails to solve the problem, proceed to the next step until the problem is resolved.

2. Click the Windows desktop Start button; select the Settings menu item; then, select the Control Panel menu item.

3. Double-click the System icon.

4. Click the Device Manager tab.

5. If the small box to the far left of the "Ports (COM & LPT)" entry contains a "+", click once on the "+" to show all your communication and line printer ports.

6. In the Configuration utility, click once to highlight the line containing the LPT port you chose to use with WaveBook.

7. Click the Properties button.

8. The Device Status section should contain the message “This device is working properly.” If the message is not present, either the wrong I/O address is selected, or the hardware is missing or broken.

9. Click the Resources tab.

10. The Resource Settings section should contain entries for “Input/Output Range” and “Interrupt Request” with “Settings” from the table below that correspond to the LPT port chosen for WaveBook.

Note: A “Direct Memory Access” entry may also exist for EPP or ECP printer ports. Printer Port Input/Output Range Interrupt Request

16. Run the Configuration utility and test WaveBook’s communication. If problems persist and no resource conflicts exist, perform the following steps:

16a. Check for loose cable connections and verify the MODULE POWER indicator is ON. 16b. Verify that the computer's printer port and data cable work with a printer or other device. 16c. Verify there are no installed devices that Windows 95/98/Me does not recognize but whose resources might conflict with the WaveBook. 16d. Verify that WaveBook works on another PC (from a different manufacture if possible).

Parallel Port Troubleshooting Tips

Windows9x Users

After completing the test hardware function within the DaqConfig control panel applet. It is possible that a connection may not be made. Before doing anything else, try the following:

Recheck your parallel port cable and the power supply so you are certain that the connection is tight and power is applied

Try all of the communication protocols listed in the DaqConfig icon because it is possible that the parallel port has a communication protocol other than standard or normal mode.

If you still have not established communication, then go to control panel, system, device manager, ports, LPT1 and verify that the following things are true:

Under the general and driver sections, make sure that the parallel port is a standard parallel port with a driver installed and that no resource conflicts are present. If no driver is installed or resource conflicts are present, then you need to resolve these issues with your computer supplier or your information services department.

Under the resource section, make sure that the parallel port has an interrupt level assigned. If it doesn’t you will need to add one by unchecking the use default settings box, selecting configuration one so the same base address is maintained but an interrupt level is added, and then double clicking on the interrupt level so you can add the interrupt level. Generally, 7 is reserved for parallel ports but you should pick one where no conflict exists. Reboot the computer and everything should work If you find that the parallel port is configured as an ECP parallel port, then you will need to access the bios and change the parallel port to a standard or normal mode. You can generally access the bios by pushing F2 or escape during the initial boot up of the computer. If so, you will see a computer message “Push F2 to enter setup”. Change the parallel port mode from ECP to standard or normal. Reboot the computer and everything should work.

If the drivers are not installed, then you need to resolve this issue with your computer manufacturer. Verify that your parallel port interrupt has an interrupt level assigned to it by looking at the parallel port resources in daqconfig applet.

If it is necessary to add an interrupt level or to change to parallel port communication protocol, that must be done in the BIOS, which can generally be accessed during computer boot up. You should see the message “Push F2 to enter setup”. If the parallel port is configured for ECP or EPP, change it to standard or normal and everything should be fine.

Frequently Asked Questions

(1) Topic: Environmental Factors

Question: What Environments are WaveBook Systems Intended for? Answer: WaveBook Systems are designed to operate within 0° to 50°C ( 32° to 122°F) and with a

relative humidity of up to 95%RH, non-condensing. The products can be stored at temperatures within the range of -20° to +70°C (-40° to 158°F). WaveBook systems should always be protected from snow, rain, extreme dust, and harsh sun.

2) Topic: 32-Bit API Support, DaqX

( Question: I am writing my own application that interfaces to the WaveBook. Is the 32-bit enhanced mode

support for Windows 95, Windows 98 and Windows NT available?

Answer: Yes, the current version of the DaqX software supports 32 bit enhanced mode programming.

Question: What is DaqX software? Answer: DaqX software is low-level software support for application development. DaqX is installed

during the installation of the WaveView application. DaqX supports Visual C++, Visual Basic, and Delphi p rogramming environments.

Question: Where can I get the latest version of WaveView/DaqX software? Answer: You can download the latest versions from our website. This service is free.

(3) Topic: WBK14 - Dynamic Signal Conditioning Module

Question: Why can't I use the external clock feature on the WBK14 to control my acquisition speed? Answer: The external clock on the WBK14 is used to dynamically move the corner frequency of the

filter, not pace the A/D in the WaveBook. This feature is often required in vibration applications where the filter is moved as the device under test is vibrated (or excited) at varying frequencies. Unlike the WaveBook/516 that has a special input for clocking the A-to-D, the WaveBook/512 has no provisions to do so.

Question: Is there anything special I should know about WBK14’s power-up state? Answer: At power-up the current output of the WBK14 is open circuited. It is only after being

programmed that the current source is engaged.

Question: In regard to attenuation, what is the filter roll-off for the WBK14 filter? Answer: The WBK14's Butterworth filter is down 3 dB at the corner frequency. Beyond that point, the

signal attenuates at 48 dB per octave or 160 dB per decade. This is a substantial amount of attenuation for most applications.

Troubleshooting 6-7

(4) Topic: WBK20 - PCMCIA/EPP Interface Card

Question: How do I configure the WBK20 in Windows 95 or Windows 98? Answer: Insert the WBK20 into the PCMCIA slot. Windows 95/98 should recognize it and display a

window 'New Hardware Found' followed by a window 'Building driver data base'. Select the option 'Select driver from disk provided by hardware manufacturer'. 'Install from

disk' is the next window. Provide a path to the floppy drive after you have inserted the disk that came with the WBK20. It contains a file 'IOTWBK20.INF'. Select OK.

In the next window, select 'IOtech Inc' in the left box and 'IOtech WBK20: 1 Parallel Port' in the right box. Select OK. At this time, it may ask for your Windows CD or certain diskettes. Then you will be prompted to restart the computer.

The WBK20 will show up in ControlPanel/System/Device Manager/ Ports (COM and LPT) as 'IOtech WBK20: 1 Parallel Port LPT#'. Double clicking on this will show you the resources (IRQ and I/O range).

(5) Topic: ECP and EPP

Question: My computer uses ECP. Is ECP the same as EPP? Answer: No; ECP (Enhanced Capabilities Port) is a different protocol than EPP (Enhanced Parallel Port).

If the WaveBook fails to communicate in ECP mode, make certain that the WaveBook hardware is actually capable of ECP communications. This can be done as follows:

1. Locate the LPT port communications chip on the main board, near the connector that the parallel cable connects to. The chip is relatively large and is stamped “262-0301,” or “262-0301, rev B.” A 262-0301 rev. B" chip supports ECP, the earlier rev does not. Contact the factory in regard t o upgrading. No te that most units purchased before July

2000 do not have ECP support.

3. Verify the parallel port is configured [in the Windows Control Panel] as an "ECP parallel port" and not "Parallel port."

(6) Topic: Sampling Rates

Question: Does the WaveBook really collect data at 1 MHz and what should I expect on my PC? Answer: Yes, the WaveBook samples at 1 MHz. But your computer may not. The PC’s performance is a

function of the hardware configuration, operat ing system, background ta sk, and other fac tors. The PC could very well be a bottleneck in regard to sampling.

Question: What transfer speeds can I expect from a standard 8-bit parallel port? Answer: A typical computer will achieve 80K to 90K samples/sec [through-put to the PC].

6-8 Troubleshooting

05-22-01

WaveBook User’s Manual

Question: I realize that the WBK20A and WBK21 are interface options. Will they improve my speeds? Answer: In the majority of cases, by far, both products result in higher through-put [than you would see

with the use of the standard 8 bit port. The exact amount varies with PC configuration. When using the WBK21, ISA plug-i n board, 1 MHz through put is more the rule t han the exception. Because this boards sits directly on the bus, most computers can handle the data rate. The WBK20A (PCMCIA card) plugs into the PC-card slot on the side of the notebook PC. Up until early 1997, all notebooks with these slots were PCMCIA type. In these older computers, 1 MHz was often seen, but 750-800 kHz was typical. In early 1997 notebooks started shipping with a PC card bus instead of the PCMCIA card slot. This change was almost completely transparent to PC users since the PCMCIA card plugs in and the PC Card bus is backward compatible with PCMCIA cards. However, one important change occurred. The WBK20A appears to operate slower in the new PC Card slot. With this change, 1 MHz transfer rates using the WBK20A in a PC Card slot are almost non-existent, instead, 300K to 500K samples/sec is typical.

Question: I'm using the WBK20A but because of my PC architecture, the system is still slower than I

require. What else can I do?

Answer: One op tion is to install a WBK30 memory card. This increases the FIFO buffer inside the

WaveBook. While this option does not increase transfer speeds, it does extend the length of time an acquisition can run before a buffer over flow occurs. The exact duration is a function of sampling rates and transfer speeds. For example, assume you are using a WaveBook/512 in packed mode with the WBK30/128. This option holds 128 Mbytes (64 Msamples) of data. Furthermore, let us say you are digitizing at 1 MHz and transferring data at 400 Ksample/sec via a WBK20A. In this case, you could expect to acquire data for about 1 minutes and 51 seconds. In that amount of time, you would have collected about 148.7 Msamples. This is over a quarter gigabyte of data.

(7) Topic: Calibration

Question: Should I calibrate my WaveBook system when I receive it? Answer: No; because each WaveBook-related product is factory-calibrated to its rated accuracy before it

leaves the factory.

Question: When is calibration required? Answer: Depending on your operating guidelines, your equipment will require periodic calibration to

ensure the original accuracy is maintained. We recommend that you have your WaveBook system calibrated at least once a year. In addition, calibration is required whenever a change is made to the signal path, for example, adding a WBK11 to the system. Note that the WaveCal Document Module provides information regarding an out-of-the-box software application that has been designed for calibr ating WaveBook systems. You can launch WaveCal from the WaveBook software program group.

Question: Can WaveCal be used to calibrate WBK17 modules? Answer: No. WaveCal is not supportive of WBK17. Consult the factory regarding WBK17 calibration.

(8) Topic: Computers for Data Acquisition

Question: What type of computer do you recommend for use with data acquisition devices such as

WaveBook?

Answer: When selecting a computer for use as a data acquisition system look for a fast parallel port, disk

drives with high rotation speeds and low access times. If you are using a notebook PC, it should have a PCMCIA or PC Card slot.

We recommend that you use a PC with more than 16 Mbytes of RAM with a Windows 95 (or higher version) operating system. While RAM does not influence transfer speeds per se, it will benefit the Windows operating system in operational areas other than transfer speed.

Note that processor speed usually has less bearing on transfer rates than one might suspect, although you may want the speed for other things such as number crunching or scrolling waveforms. A 400 MHz Pentium might not transfer as fast as a 75 MHz Pentium.

(9) Topic: WaveView

Question: WaveView can communicate with my WaveBook/512, but does not detect the WBK options and

does not acquire data. What could be wrong?

Answer: Mo st likely the parallel port interr upt WaveView is trying to use has a conflict or is not

operating. Try another interrupt setting.

Buffer

A collection of scans acquired at a specified rate as controlled by the sequencer.

A signal of varying voltage or current tha t communicates data.

A circuit or device that converts analog values into digital values, such as binary bits, for use in

digital computer processing.

Application Program Interface. The interface program within the Daq* system’s driver that

includes function calls specific to Daq* hardware and can be used with user-written programs (several language s supported).

A range of analog signals with positive and negative values (e.g., -5 to +5 V); see unipolar.

Buffer refers to a ci rcuit or devi ce that allows a signal to pass through it, while providing

isolation, or another function, without altering the signal. Buffer usually refers to:

(a)

A device or circuit that allows for the temporary storage of data during data transfers. Such storage can compensate for differences in data flow rates. In a FIFO (First In - First Out) buffer, the data that is stored first is also the first data to leave the buffer.

(b)

A follower stage used to drive a number of gates without overloading the preceding stage.

(c)

An amplifier which accepts high source impedance input and results in low source impedance output (effectively, an impedance buffer).

Buffer Amplifier

Channel

Common mode

voltage

Crosstalk

Detection Signal

An amplifier used primarily to match two different impedance points, and isolate one stage from

a succeeding stage in order to prevent an undesirable interaction between the two stages. (Also see, Buffer).

In reference to Daq*, channel simply refers to a single input, or output entity.

In a broader sense, an input channel is a signal path between the transducer at the point of

measurement and the data acquisition system. A channel ca n go through various stages (buffers, multiplexers, or signal conditioning amplifiers and filters). Input channels are periodically sampled for readings.

An output channel from a device can be digital or analog. Outputs can vary in a programmed

way in response to an input channel signal.

Common mode pertains to signals that are identical in amplitude and duration; also can be used

in reference to signal components.

Common mode voltage refers to a vol t age magnitude (referenced to a common point) tha t is

shared by 2 or more signals. Example: referenced to common, Signal 1 is +5 VDC and Signal 2 is +6 VDC. The common mode voltage for the two signals is +5.5 VDC [(5 + 6)/2].

An undesired transfer of signals between systems or system components. Crosstalk causes signal

interference, more commonly referred to as noise.

In relation to WBK17, a detection signal is one of 8 outputs of the pattern detection module.

Each input channel has an associated detection signal (Detect 1 for Channel 1, Detect 2 for Channel 2, etc.) A channel’s detection signal will go active high when that channel’s counter value meets the setpoint criteria programmed into the pattern detection module. Detection signals can be scanned along with any other channel in the scan group.

Digital-to-Analog

Converter (DAC)

DIP switch

Differential mode

Encoder Mode

A digital signal is one of discrete value, in contrast to a varying signal. Combinations of binary

digits (0s and 1s) represent digital data.

A circuit or device that converts digital values (binary bits), into analog signals.

A DIP switch is a group of miniature switches in a small Dual In-line Package (DIP). Typically,

users set these switches to configure their particular application.

The differential mode measures a voltage between 2 signal lines for a single channel. (Also see

single-ended mode).

Differential mode voltage refers to a voltage difference between two signals that are referenced to

a common point. Example: Signal 1 is +5 VDC referenced to common. Signal 2 is +6 VDC referenced to common.

If the +5 VDC signal is used as the reference, the differential mode voltage is +1 VDC

(+ 6 VDC - +5 VDC = +1 VDC).

If the +6 VDC signal is used as the reference, the differential mode voltage is -1 VDC

(+ 5 VDC - +6 VDC = -1 VDC).

The encoder mode allows the WBK17 to make use of data from optical incremental quadrature

encoders. When in the encoder mode, the WBK17 accepts either differential or single-ended inputs and provides power for up to four encoders. When reading phase A, phase B, and index Z signals, the WBK17 provides positioning, direction, and velocity data.

ESD

Excitation

Gain

Gating

Isolation

Electrostatic discharge (ESD) is the transfer of an electrostatic charge between bodies having

different electrostatic potentials. This transfer occurs during direct contact of the bodies, or when induced by an electrostatic field. ESD energy can damage an integrated circuit (IC); so safe handling is required.

Some transducers [e.g. strain gages, thermistors, and resistance temperature detectors (RTDs)]

require a known voltage or current. Typical ly, the variation of this signal through the transducer corresponds to the condition measured.

The degree to which an input signal is amplified (or attenuated) to allow greater accuracy and

resolution; can be expressed as ×n or ±dB.

In relation to the WBK17, any counter can be gated by the mapped channel. When the mapped

channel is high, the counter will be allowed to count, when the mapped channel is low, the counter will not count but hold its value.

The arrangement or operation of a circuit so that signals from another circuit or device do not

affect the isolated circuit.

In reference to Daq*, isolation usually refers to a separation of the direct link between the signal

source and the analog-to-digital converter (ADC). Isolation is necessary when measuring high common-mode voltage .

Mapped Channel

In relation to the WBK17, a mapped channel is one of 16 signals that can get multiplexed into a

channel’s counter module. The mapped channel can participate with the channel’s input signal by gating the counter, clearing the counter, etc. The 16 possible choices for the mapped channel are the 8 input signals (post debounce) and the 8 detection signals.

Multiplexer (MUX)

Sample (reading)

Scan

Sequencer

Simultaneous

Sample-and-Hold

Single-ended mode

Start of Scan

Terminal Count

Ticksize

A device that collects signals from several inputs and outputs them on a single channel.

The value of a signal on a channel at an instant in time. When triggered, the ADC reads the

channel and converts the sampled value into a 12- or 16-bit value.

The channels that are selected for sampling.

A programmable device that manages channels and channel-specific settings.

An operation that gathers samples from multiple channels at the same instant and holds these

values until all are sequentially converted to digital values.

The single-ended mode measures a voltage between a signal line and a common reference that

may be shared with other channels. (Also see differential mode).

In relation to the WBK17, “start of scan” is a signal that is internal to the WBK17. It signals the

start of a scan group and therefore pulses once every scan period. It can be used to clear the counters and latch the counter value into the acquisition stream.

In relation to theWBK17, this signal is generated by the counter value. There are only two

possible values for the terminal count: 65,535 (for a 16-bit counter) and 4,294,967,295 (for a 32-bit counter.) The terminal count can be used to stop the counter from rolling over to zero.

In relation to theWBK17, the ticksize is a fundamental unit of time and has four possible settings:

20ns, 200ns, 2000ns, 20000ns. For measurements that require a timebase reference like period or pulsewidth, the ticksize is the basic unit of time. The count value returned in the scan is the number of ticks that make up the time measurement.

Trigger

TTL

Unipolar

An event to start a scan or mark an instant during an acquisition. The event can be defined in

various ways; e.g., a TTL signal, a specified voltage level in a monitored channel, a button manually or mechanically engaged, a software command, etc. Some applications may use preand post-triggers to gather data around an instant or based on signal counts.

Transistor-Transistor Logic (TTL) is a circuit in which a multiple-emitter transistor has replaced

the multiple diode cluster (of the diode-transistor logic circuit); typically used to communicate logic signals at 5 V.

A range of analog signals that is always zero or positive (e.g., 0 to 10 V). Evaluating a signal in

the right range ( uni polar or bipolar) allows greater r esolution by using the full-range of the corresponding digital value. See bipolar.
