SWITCH/MEASURE SYSTEMS

Integra Series Multimeter/Switch Systems

Introduction

The Integra Series of 6

⁄2-digit Multimeter/Switch systems blends Keithley’s high performance DMM technology, switching expertise, and data acquisition knowledge into compact, affordable, easy-to-use packages. This technical data booklet provides a comprehensive overview of the systems and includes detailed specifications.

There are three Integra systems: the Model 2700, 2701, and 2750. Each consists of a mainframe and a growing line of plug-in switch/control modules. The Model 2700 and 2701 each include two slots for the plug-in modules; the Model 2750 has five slots. Each slot can support a series of multiplexer, matrix, or control modules, and all the modules in a system operate simultaneously. Input modules can be mixed or matched to provide a broad range of measurement, acquisition, and control capabilities.

While the core functionality and programming of all Integra Series systems are identical, each mainframe has unique capabilities. For example, the Model 2701 is the only system to provide a 10/100BaseTX Ethernet interface, and the Model 2750 provides extended low ohms measurement capability.

Setting up an Integra system is simple and straightforward. When a plug-in module is inserted into a slot, it is ready to be used immediately. Settings can be configured from the front panel of the system or via the computer controller (over GPIB, RS-232, or Ethernet). Also, each channel can be configured independently.

If you have any questions after reviewing this information, please contact your local Keithley representative or call one of our Application Engineers at 1-800-552-1115 (U.S. only). Check Keithley’s website, www.keithley.com, for the names and numbers of our representatives around the world.

Channel Configuration Capabilities — Scanning Capabilities

SWITCH/MEASURE SYSTEMS

Integra Series Multimeter/Switch Systems

Channel Configuration Capabilities

• Measurement functions: An Integra system can measure many different parameters: DC voltage, DC

current, AC voltage, AC current, 2-wire Ω, 4-wire Ω, voltage clamped Ω (2750 only), temperature

(using thermocouples, RTDs, and thermistors), frequency, period, and continuity.

• Math functions: A variety of math functions are available at the push of a button, including channel

average and ratio, mX+b scaling, min, max, average and standard deviation. All are available on a per-

channel basis.

• Measurement setup: Each channel can be configured independently for making measurements.

Selectable channel parameters include:

• Speed

•Range

• Resolution

• Number of power line cycles (NPLC)

• Math functions

•Ratio calculation

• Individual “m” and “b” values in mX+b format

• Channel averaging

•Hi-Low limits

• Resistance measurement method (2- or 4-wire)

• Offset compensation

• CJC type

• Thermistor type

• Thermocouple type

•RTD type

•Voltage clamped ohms (Dry Circuit, 2750 only)

• DUT-to-modules connections: It is easy to connect the device under test to the switch/control modules. The 7703 and 7705 modules use dual 50-pin “D-sub” input connectors for secure, quick connections. The 7701, 7707, and 7709 modules use “D-sub” connectors that are compatible with off-the-shelf standard ribbon cable. These connectors are especially convenient for rapid system setup. When greater connection flexibility is required, the 7700, 7702, and 7708 modules provide oversize screw terminal connectors that simplify setup by eliminating the need to handle small connectors. The standard wires used are 20AWG. Model 7710 uses removable terminal blocks to provide the simplicity of screw terminal connections with the speed of mass terminated cables. The 7711 and 7712 RF modules use industry standard SMA connectors.

• Mainframe-to-modules connection: Secure screws connect the modules to the mainframe. At power-up, the mainframe detects any attached modules automatically, which minimizes set-up time. All signals are routed internally from module to mainframe.

• Front/rear switch: The front inputs are used for manual probing, troubleshooting, and calibration. A switch on the front panel makes it easy to shift between the front and rear inputs. This eases setting up the equipment and speeds verifying proper setup and connections prior to automating the measurement.

Scanning Capabilities

•Relay Closure Counts: Relay closure counts are logged every time a channel is closed. These counts are permanently written to the EEPROM on the module at a user-settable time interval (factory default of 10 minutes) or whenever the counts are queried. Valid intervals (set in integer number of minutes) are between 1 and 1440 minutes (24 hours). Relay closures are counted when a relay cycles from open to closed state.

• Open Sense Lead Indication. The system can alert the user if there is a sense lead disconnection on any channel. In this case, the front panel display will show “OVERFLOW.” Therefore, the system does not need other equipment or calibration to inspect the broken connection or failed relay on the scanner card. In addition, the system will protect against erroneously passed conditions.

• Scan count: An Integra Series system can be programmed to run a given number of scans (up to 450,000) automatically and to record readings into the internal memory buffer. The instrument also allows programming the trigger source used to initiate each scan. (Refer to page 11 for more information on triggering.)

Scanning Capabilities — Choice of Communication Interfaces

SWITCH/MEASURE SYSTEMS

Integra Series Multimeter/Switch Systems

• Scan interval: The user can set the interval after which each succeeding scan will begin. Scan intervals can be set anywhere from 0 to 99 hours in increments of 1ms.

• Scan sequence/omitting channels: In addition to scanning in numerical sequence, the system can be programmed to skip any channels that are not required for a particular test. This avoids recording irrelevant data and speeds the data acquisition process. This makes scanning both faster and more flexible.

• Ratio (DCV only): The instrument can calculate and display the ratio of measurements of paired channels. Ratios can only be determined for specific channel pairs, depending upon the input module used. For example, channel pairs on the Model 7702 include Channels 1 and 21, Channels 2 and 22, etc. Hi/Lo limits are fully supported.

• Channel average (DCV and thermocouple only): The instrument can calculate and display the average of two channel measurements. As with ratio calculations, only paired channels can be averaged. Hi/Lo limits are fully supported.

Choice of Communication Interfaces

RS-232

All the Integra Series mainframes include RS-232 ports for computer control. RS-232 is a low cost point-topoint interface, allowing a computer to interface with a one mainframe per port at distances up to several hundred meters, depending on the baud rate setting. Slow baud rates can be run long distances, while the fastest baud rate settings are limited to several meters maximum distance. The Model 2700 and 2750 can receive commands and transfer data via RS-232 at various baud rates up to 19.2kBaud. The Model 2701 offers data rates up to 115.2kBaud with hardware handshaking.

GPIB

The Model 2700 and 2750 both offer a GPIB port. GPIB provides higher speed data transfers (up to 1Mbyte/sec.) than RS-232, and allows up to 32 devices to addressed from a single GPIB controller card in a host computer. The maximum cabling distance for the GPIB interface is 2 meters between each GPIB connection. Up to 20 total meters of cable may be connected to a single controller card.

Ethernet

The Model 2701 offers a 10/100 BaseT Ethernet connection for high speed and long distance communication between a computer and a virtually infinite number of instruments. Any PC with an Ethernet port can connect to a single Model 2701 in a point-to-point configuration, to multiple 2701s through a hub, or to multiple 2701s distributed on a network. See the system configuration section on page 35 for more details on Ethernet connections.

The Model 2701 Ethernet port uses the industry-standard TCP/IP socket interface. This provides data rates up 100Mbits/sec. and allows the instrument to be located up to 100 meters from the nearest computer or network hub in hardwired systems and miles in wireless Ethernet systems. The maximum distances between a control PC and the instruments are limited only by the size of the network. The instrument also provides a built-in diagnostic web page for easy remote access to the 2701. Entering the instrument’s IP address in the URL line of Microsoft

Internet Explorer®will allow communication with and control of the 2701. This Web page allows users to read and set network parameters, such as IP address, subnet mask, gateway, MAC address, and calibration dates, and to send commands to and query data from the 2701.

way to take a measurement on a single channel.

is very precise (<0.5ms trigger latency) and provides tight timing control for synchronization in larger systems. Therefore, measurements can be taken at a precise time with very little uncertainty. This capability can be valuable when optimizing coordination with other system instruments, such as the Model 2400 SourceMeter

instrument in larger rack & stack applications.

C. A bus trigger is received (GET or *TRG) on GPIB or *TRG on RS-232 and Ethernet.

D. Manual: Use of front panel TRIG key.

E. Analog trigger: A display reading on a particular channel can be programmed as an analog trigger. A

scan sequence is started whenever such a reading is reached [programmed for either a greater than (>) or less than (<) condition as a trigger]. In other words, this feature can be used to initiate a scan sequence based on some external factor, such as a temperature rising above a pre-set limit. After scanning all the configured channels on the instrument, the instrument then returns to the channel that acted as the analog trigger, and checks for the reading to be in conditional limits. Depending on the limits and current reading, the instrument decides whether to start the next scan. Only the data of interest are acquired, eliminating the need to spend hours searching through reams of normal readings to find anomalous data.

F. Digital trigger: Two digital inputs (TTL-level) are standard on each mainframe—one

to serve as a trigger input and one to serve as a hardware interlock. The digital trigger is logical “and”ed with the interlock. The interlock is default true. Therefore, the digital trigger input would be recognized for triggering only when the digital trigger and the interlock are both true. Thus, the interlock provides the user with a controlling mechanism for recognizing the digital trigger if necessary (see Figure 3).

Alarm Limits/Digital Outputs

The digital output lines can trigger external alarms without the need for a PC connection. The instrument can be programmed to provide alarms when any pre-set limits are breached. Limits can be applied to all measurement functions except continuity, which has its own alarm beeper. The limit test is performed after “mX + b” and math operations.

Limit types: Each channel has four independently programmable limits, each of which can be assigned a value. These are:

1. Limit1 High (for example, 1% higher than the expected reading)

2. Limit1 Low (for example, 1% less than the expected reading)

3. Limit2 High (for example, 5% higher than the expected reading)

4. Limit2 Low (for example, 5% less than the expected reading)

The outputs can be positive or negative true, pulse, or fixed level. Pulse widths are programmable.

Master Limit: In addition to these limit alarms, a master limit is provided. It is logically “or”-ed with the four limits and is active every time any of the other limits are breached.

Each of the alarm limits and the master alarm is mapped to a specific output pin on the 9-pin male connector that handles the output of that alarm limit.

Electrical Capabilities:

• 250mA sink (output).

• TTL level outputs (no external supply is needed).

• Open collector output up to 33V with external supply.

• Ability to trigger or start a scan by connecting to one of the digital input lines.

On-board Data Storage

Buffer: There are non-volatile “read and transmit” memory buffers (in other words, the buffer can be emptied while it is being filled) in each system. The buffer can be configured in “wrap around” mode for recording readings continuously for long periods. There is no need to stop taking data, reset the instrument, or change memory cards. The wrap around memory can be configured to issue a Service Request (SRQ) at predetermined points in the scan. An SRQ can be issued when the buffer is one-quarter full, one-half full, three-quarters full, or completely full. The instrument can be commanded to download the readings without interfering with the current acquisition; therefore, data acquisition and retrieval can occur simultaneously. When the buffer is full, the instrument returns to the beginning of the buffer and starts writing in the locations emptied by the previous download.

Timestamp: The readings in the memory can be timestamped to trace the progress of a test. The time can be configured as either:

• Real time: The actual calendar day and time.

• Relative Time: Time is relative to the first reading stored in the buffer.

SWITCH/MEASURE SYSTEMS

Integra Series Multimeter/Switch Systems

Saving/Recalling a Setup

All current set-up information for individual channels and the mainframe is battery backed and the measurement data is stored in the non-volatile memory. Therefore, while the instrument is switched off, the configuration for each channel is saved in the memory, then automatically recalled when the product is switched on again. Up to five (four for Model 2700 and three for Model 2750) different sets of setups can be recorded for each channel, so it’s unnecessary to set up each channel before a different test.

Power Failure Recovery

All set-up information is battery backed and data is stored in non-volatile RAM, so the system is immune to power failures and can resume scanning where it stopped once power is restored. There is no need to restart interrupted tests from the beginning. The scan resumption feature is user-selectable.

Channel Monitor

The channel monitor feature allows monitoring any specific input channel on the front panel display at any time during a scan. The system can scan across channels very rapidly, so the channel monitor offers a convenient way to view only the channel of interest without interrupting a scan.

Keithley’s patented measurement engine provides true 6

Measurement Performance

Each Interga series system is a true 61⁄

2-digit (22-bit) instrument

designed for high measurement precision. Its high precision enhances measurement repeatability and stability.

Measurement performance is a key advantage of all of Keithley’s products. The Integra Series is based on a number of advanced technologies that improve its overall performance dramatically, including:

• Patented A/D converter IC circuitry design to increase the resolution, precision, and speed of measurement.

• Advanced signal conditioning hardware to filter out unwanted noise and provide necessary isolation.

•A unique “servo” front end design (Figure 6). While conventional DMMs typically measure and correct for the zero drift of front-end circuitry, these systems’ servo front end eliminates zero drift, which also eliminates the wasted measurement time usually required to check zero, further increasing measurement speed.

Digital Filtering — NPLC — Line Cycle Synchronization — Autozero — Low Ohms Measurement

SWITCH/MEASURE SYSTEMS

Integra Series Multimeter/Switch Systems

Digital Filtering

For each major measurement function, users can employ either averaging or advanced digital filtering to reduce noise and increase the effective resolution.

Averaging Filter

The averaging filter operates over a range of from two to 100 readings. All readings included in the filter range are weighted equally. A step input of any size will ramp up linearly to the final value after obtaining the number of readings specified by the user. The averaging filter may be configured as either a moving averaging or as a repeat filter. Operation over the GPIB bus is often done in “repeat” mode to ensure that all readings are fully filtered. Also, taking filtered measurements in repeat mode requires only one trigger, simplifying programming. Only the repeat filter can be used while scanning.

Advanced Filter

When a DMM is used in bench mode, it’s often desirable for it to respond immediately upon connection to a test point, without the slow response associated with an averaging filter. The advanced filter addresses this need by providing a filter reset level. If the measured value deviates significantly from previous values, the filter is reset to the new value, and filtering is restarted. In this way, the user can set the filter reset level just above the maximum noise level anticipated and the multimeter will respond to new values immediately.

NPLC

Selectable power line cycle integration allows the user to specify the number of power line cycles (NPLC) over which to integrate (1, 5, 10, etc.). Use of line cycle integration provides rejection of noise from line cycle interference, the most common source of noisy readings. In general, the longer the integration time chosen, the greater the noise rejection will be. The system can also be set to less than 1 NPLC integration time, as fast as 0.002 NPLC (~33µs at 60Hz) in the Model 2701 and 0.01 NPLC (~167µs at 60Hz) in the Model 2700 and 2750 for faster data measurement (but without power line noise rejection).

Line Cycle Synchronization

To attain the highest possible line cycle noise rejection, it is important to trigger the reading at the beginning of a power line cycle. The system can be set to start a measurement precisely when the power line signal crosses zero (see Figure

7). This function increases the normal mode noise rejection 30dB, providing an

additional ×30 reduction in noise due to line cycle interference.

Autozero

Internal autozeroing is used to maintain the best measurement performance. The advanced firmware design does the required calculation, such as CJC com-

pensation for thermocouple measurements with the 7700, 7706, 7708, and 7710, automatically in the background. This enables the Integra system to provide faster reading rates (competitive products spend half their measurement time validating their own zero). Autozero can be disabled to increase measurement speed, but this may result in greater measurement uncertainty.

Low Ohms Measurement (Model 2750 only)

The Model 2750 can measure low ohms on all of its switch/control modules that have multiplexers or matrix configurations. The four-wire ohms measurement supports low ohms measurements down to the

1Ω range, with micro-ohm resolution. Measurements can be accommodated through ribbon cable or

discrete wiring. On four-wire ohms measurements, up to five additional ohms of cable/switch card resistance can be tolerated per cable lead. This allows the use of ribbon cable without overloading the range.

Offset Compensation — Voltage Limit/Dry Circuit Ohms — Temperature Measurements

SWITCH/MEASURE SYSTEMS

Integra Series Multimeter/Switch Systems

Offset Compensation

For more accurate low resistance measurements, all Integra systems provide the offset compensation mode to eliminate errors from the thermoelectric EMF effects (V

EMF

). During the measurement cycle, the

built-in ohms current source is turned off, then turned on again, and the resulting EMF error is automati-

cally subtracted. This technique is typically used when measuring values less than 100Ω using the four-

wire ohms method.

Voltage Limit/Dry Circuit Ohms (Model 2750 only)

The use of dry circuit mode, when selected, limits the open-circuit voltage to 20mV. This allows resistance measurements to be made with low power. When measuring contact and connector resistances, it is important not to puncture oxides and films that may have formed. Standard resistance measurements have open-circuit voltage levels from 5.4V to 12.8V, depending on the selected range.

Dry circuit ohms can be used on the 1Ω, 10Ω, 100Ω, and 1kΩ ranges for the four-wire ohms (Ω4) func-

tion. Also, offset compensated ohms (OCOMP) can be used with dry circuit ohms to cancel the effect of thermoelectric EMFs.

Dry circuit ohms should be used for any device that could be damaged by high open-circuit voltage. If not sure, and the slightly degraded accuracy is not a consideration, it is good practice to use dry circuit ohms to measure low resistance.

The accuracy specifications for all dry circuit ohms ranges are with offset compensated ohms and line synchronization enabled.

Temperature Measurements

The Integra systems support three major types of temperature sensors with built-in signal conditioning and linearization: thermocouples, RTDs, and thermistors.

Temperature Measurements — Calibration

SWITCH/MEASURE SYSTEMS

Integra Series Multimeter/Switch Systems

Cold Junction Compensation Methods

Thermocouple measurements always require that the temperature be known at the point where the thermocouple is connected to the instrument. This connection point is known as the “cold junction.” The Integra systems support three different methods for including this “cold-junction” temperature in the temperature measurements.

Automatic CJC

The CJC sensors are mounted on the multiplexer module’s PC board (7700, 7706, 7708, and 7710). They sense the actual temperature across the module’s connector, then compensate all temperature measurements accordingly. The CJC scaling is done automatically when autozero is turned on, so the user does not have to acquire it separately. When autozero is turned off, the instrument is optimized for speed and does not refresh the CJC compensation. This allows the user to obtain faster scan rates for short periods of time while ambient temperature remains stable.

External CJC

A thermistor or RTD is attached to Channel 1 by the end user. This thermistor or RTD is then used to measure the temperature of the point(s) where the thermocouples are connected to the instrument or to copper wires leading to the instrument. The precision of the actual temperature measurement depends on the accuracy of the cold junction reading and how close the sensor is to the actual temperature of the connection.

Simulated CJC

When the “change” in temperature is of interest rather than the absolute temperature value, the user can enter a parameter as a cold junction reference point (for example, 23°C for room temperature). This parameter will be used to adjust the actual temperature measurement for each channel. This simulated temperature must be updated manually if ambient conditions change. This is also the method used when an actual ice bath is used to establish a cold junction of 0°C. The simulated parameter is then set to 0°C or 32°F.

Open Thermocouple Detect

A system can alert the user if any thermocouple becomes broken or otherwise disconnected from the input terminal blocks. When the Open T/C Detect feature is enabled, the system will perform (in the background) a two-wire resistance measurement across each thermocouple input channel. If an open connection is detected, the front panel display will show “OVERFLOW” for that channel.

Calibration

The design of the Integra Series and their calibration procedure were developed to address a variety of critical calibration issues. For example, the systems have front panel input jacks, so there’s no need to disassemble the system for periodic recalibrations. There’s also no need to buy, stock, and track spare “cal only” modules. The systems are connected to the calibrator through the front panel input jacks. The systems’ calibration procedure covers both verification and adjustment and can be performed through either the front panel or any of the remote interfaces. The calibration interval is user-selectable.

For building custom applications, programmers can take advantage of the VISA based Integra series IVI driver designed for use with software development environments like Visual Basic, Visual C/C++, LabVIEW, LabWindows/ CVI, and TestPoint. The VISA (Virtual Instrument Software Architecture) layer of the driver allows the programmer to quickly reconfigure the communication bus between the PC and the instruments without changing a single line of source code. This means that changing GPIB control board vendors or switching the communication bus between GPIB, RS-232, and Ethernet requires no rework of a custom application program. The IVI (Interchangeable Virtual Instrument) layer of the driver provides a simplified command interface that is common to the entire Integra Series product family. The driver also includes a large set of examples for reference during software design.
