Signal to be measured

Chapter 1 What the Acquisition Software Can Do

1.1 Overview of This Software

The Acquisition Software is used to connect to an SL1000 via the USB interface or the optional Ethernet interface and record and display data that the SL1000 has measured. The Acquisition Software allows you to do the following:

• Set measurement and record conditions of an SL1000.

• Start and stop measurements on an SL1000.

• Start and stop recording.

• Display waveforms of the measured data, cursor values, and waveform parameters.

• Synchronize the operation of up to eight linked SL1000s.

• Start the Xviewer (accompanying software) and display waveforms of data saved in the past (excluding the /XV0 option)

Signal and Data Flow

The signal and data flow between this software and the SL1000 is described below.

Display Data

P-P compression data that the SL1000 creates for displaying waveforms. The data is sent to your PC in unit of measuring groups. For a description of display groups, see section 1.5.

Measured Raw Data

All the measured data that the SL1000 acquired. The data is sent to your PC in unit of measuring groups to save the data on the hard disk of your PC. For a description of measuring groups, see section 1.2. The data is used in data analysis such as cursor measurements and waveform parameter computations.

Current Value Data

The current values that the SL1000 calculated. The data is sent immediately upon a request from your PC.

Signal to be measured

1.1 Overview of This Software

Measurement and Recording

This software refers to the task of acquiring measured data into the internal memory of an SL1000 as measurement and the task of saving the measured data that has been acquired to the internal memory of an SL1000 as files on your PC’s hard disk or the internal hard disk of an SL1000 while making measurements as recording. The measured data acquired in the internal memory of an SL1000 is cleared when the power is turn ON/OFF or when measurement is resumed. The waveform screen of this software displays waveforms of measured data acquired to the internal memory of an SL1000 after applying P-P compression.

After the measurement stops, all the measured data acquired in the internal memory of an SL1000 can be saved as a single file on your PC. This task is referred to as saving not recording in which data is saved while the measurement is in progress.

Connecting to an SL1000

The USB can be used to connect your PC directly to an SL1000 or the optional Ethernet interface can be used to connect to an SL1000 over the network. Only a single SL1000 can be connected to a single PC.

Note

• Remove the USB or Ethernet cable that is connecting the SL1000 to the PC only after you

have exited the Acquisition Software or after you have disconnected the communication

between the SL1000 and the PC.

• In the default setting of the SL1000, the DHCP function is turned ON. You can immediately

connect an SL1000 to your PC by connecting the SL1000 to a network with a DHCP server.

• An exclusive driver is necessary to connect using the USB. If an SL1000 is connected

to your PC via the USB, an installation wizard starts. Install the driver according to the

instructions on the screen. For details, see section 2.3, “Installing the USB Driver.”

• You cannot connect both Ethernet and USB interfaces simultaneously to an SL1000.

You cannot connect to the SL1000 that this software is connected to via USB, using the

accompanying Xviewer (excluding /XV0) application nor using FTP.

• When connecting an SL1000 to the PC, disable the PC standby mode. If it is enabled, the

connection between the SL1000 and the PC may be disconnected.

The slave units’ external clock input, external trigger input, trigger output, and alarm output are invalid.

Synchronized Items

• Measurement and recording start and stop

• Clock

Slave units synchronize to the master unit’s external or internal clock.

• Time (The time of the slave unit is synchronized with the time of the master unit.)

• Triggering

The AND or OR logic of the master unit’s external trigger input and slave units’ trigger

sources.

When the SL1000 triggers, the trigger signal is transmitted from the master unit’s

trigger output.

• Alarms

The AND or OR logic of the slave units’ channel alarm conditions or the OR logic of

the slave units’ system alarm conditions.

When an alarm occurs, an alarm signal is transmitted from the master unit’s alarm

output.

Measuring Mode

There are two measuring modes: Free Run and Triggered.

Free Run Mode

Data is acquired immediately upon starting a measurement. The SL1000 continues to acquire data until the measurement is stopped. The measured data can also be recorded to the hard disk of the SL1000 or your PC at a specified time or when an alarm occurs. The following functions are not available in Free Run mode.

• GO/NO-GO function

• Automated measurement of waveform parameters

• Zoom on a particular section of the waveform

Triggered Mode

After starting the measurement, the SL1000 acquires data when a trigger condition is met. After acquiring data over the specified measuring time, data acquisition stops. You can also record the measured data acquired in Triggered Mode to the hard disk of the SL1000 or your PC. If Triggered Mode is used, you can perform automated measurement of waveform parameters and zoom in on waveforms. For details on triggers, see section 1.6, “Triggering.” The following functions are not available in Triggered Mode.

• Channel alarm

• Recording start and end condition settings

What the Acquisition Software Can Do

Acquisition Mode

Normal Mode

Envelope Mode

When acquiring measured data in the internal memory of the SL1000, it is possible to perform processing on data and display waveforms based on the processed data. The following three types of data processing are available.

In this mode, measured data is acquired without special processing.

If measuring at a sample rate lower than the maximum sampling rate of each input module, the SL1000 samples data at 100 S/s internally, determines the maximum and minimum values among the measured values over each sample interval at the specified sample rate, and acquires them as pairs. This mode is effective when you want to avoid aliasing because the sample rate is essentially kept high. It is also effective when you want to detect glitches (pulse signals which rise very fast) or display an envelope of a modulating signal.

1.3 Measurement Settings

Box Average Mode

Input modules with a maximum sample rate less than 100 MS/s cannot acquire data at certain points even if the internal sampling rate is 100 MS/s. The data at points that cannot be sampled will take on the same value as the previous measured data. Envelope Mode has no effect if measuring at a sample rate higher than the maximum sample rate of the input module.

This mode is available on the 701250 (HS10M12), 701255 (NONISO_10M12), 720210 (HS100M12), 720211 (HS100M12), and 720250 (HS10M12). In this mode, the SL1000 determines the moving average of the data sampled at the maximum sample rate and acquires and displays the resultant data. Box averaging is effective in eliminating small amounts of noise from the input signal. It can also remove noise from a single-shot signal.

Clock Source

Internal Clock

The sampling timing of the measured data is controlled using the clock signal (internal clock) that is generated from the internal time-base circuit of the SL1000.

External Clock

The sampling timing of the measured data is controlled using a clock signal applied externally. This mode is available when the acquisition mode is set to Normal. The external clock input is useful for observing a signal whose period varies or for observing waveforms by synchronizing to the clock signal of the signal being measured. The maximum frequency that can be used for the external clock varies depending on the module.

720210, 720211: 5 MHz 701250, 701251, 701255, 720250: 1 MHz 701267, 701270, 701271, 701275: 100 kHz 701281, 720281, 720268: 1 MHz 701261, 701262: 100 kHz when measuring voltage 500 Hz when measuring temperature

701265, 720266: 500 Hz If an external clock that exceeds the maximum frequency is applied, the data is sampled at the maximum frequency, and the measured data at times when data cannot be sampled is set to the same value as the previous sampled data. When using an external clock, the time axis unit becomes the number of measured points, not time. Therefore, the measuring time is set and the cursor measurement values are displayed in terms of the number of measured points.

1.3 Measurement Settings

Sample Rate and Sample Interval

You can set the sample rate or sample interval for each measuring group. The sample rate (the number of samples per second in unit of S/s) is related to the sample interval as follows: Sample rate = 1/sample interval The maximum sample rate varies depending on the module. If you set a sample rate that exceeds the maximum sample rate of a module, data cannot be acquired at the specified sample rate. The data at times when data cannot be acquired is set to the same value as the previous acquired data.

Note

If the sample rate of measuring group 1 is set to 50 MS/s, 5 MS/s, 500 kS/s, 50 kS/s, 5 kS/s,

500 S/s, or 50 S/s, the sample rate of other groups cannot be set to the next lower sample rate.

For example, if the sample rate of measuring group 1 is set to 500 kS/s, the sample rate of

other measuring groups cannot be set to 200 kS/s (the next lower sample rate).

The SL1000 can display waveforms correctly for frequencies less than one-half the sample rate as defined by the Nyquist sampling theorem.* * If the sample rate is comparatively low with respect to the input signal frequency,

the harmonics contained in the signal are lost. In this case, some of the harmonics will appear at low frequencies due to the effects described by the Nyquist sampling theorem. This phenomenon is called aliasing. You can avoid aliasing by acquiring waveforms with the acquisition mode set to envelope.

Input Coupling

If you want to measure only the amplitude of an AC signal, measurement is easier if the DC component is removed from the input signal. On the other hand, there are times when you want to check the ground level or measure the entire input signal (both the DC and AC components). You can change the input coupling setting to meet your application needs. By changing this setting, the way in which the vertical control circuit (voltage axis) receives the input signal is switched. The following types of input coupling are available.

The input signal is directly coupled to the attenuator of the vertical control circuit. Select DC if you want to measure the entire input signal (DC and AC components).

AC (Only When Measuring the AC Voltage)

The input signal is coupled to the attenuator of the vertical control circuit through a capacitor. Select AC if you want to measure only the amplitude of the AC signal, eliminating the DC components from the input signal.

Probe Attenuation and Current-to-Voltage Conversion Ratio

For voltage (current) measurement, a probe is normally used in connecting the circuit being measured to the signal input terminal. Using a probe has the following advantages.

• Prevents disturbing the voltage and current of the circuit being measured.

• Applies the signal with no distortion.

• Expands the measurable voltage (current) range of the SL1000.

When using a probe, the attenuation setting on the SL1000 must be set equal to the probe attenuation or current-to-voltage conversion ratio so that the measured voltage (current) can be read directly.

Set the probe attenuation for the accessory probes (sold separately) as follows:

• Isolated probe (700929): 10:1

• Current probe (700937 and 701933): 10 A:1 V

• Current probe (701930 and 701931): 100 A:1 V

• 10:1 Passive Probe for the DL750/DL750P (701940): 10:1

The SL1000 has the following attenuation settings: 1:1, 10:1, 100:1, 1000:1, 1 A:1 V, 10 A:1 V, accessories (sold separately), set the attenuation ratio on the SL1000 according to the attenuation of the probe.

The measured data can be scaled to any physical value and displayed. When measuring the voltage (current), strain, or frequency (number of rotations, period, duty cycle, power supply frequency, pulse width, pulse integration, and velocity), there are two methods of linear scaling: “aX+b” and “P1-P2.”

aX+b

The results obtained from the following computation based on the specified scaling coefficient a and offset b are displayed as cursor measurement values and automated measurement values of waveform parameters. You can also assign a unit to the result of linear scaling. Y = aX + b

P1-P2

Specify arbitrary scale values (P1Y and P2Y) for the measured values of two arbitrary points (P1X and P2X). The scale conversion equation (y = ax + b) is derived from these four values.

• Range of measured values (P1X and P2X): –9.99990E+25 to +9.99990E+25

RMS Measurement

If the module is 701267 (HV (with RMS)) or 720268 (HV (with RMS/AAF)), you can observer the RMS value of the input signal.

AC-RMS

This setting is used when you want to observe only the rms values of the AC signal, eliminating the DC components from the input signal. Example If the rms value of a 2-Vpeak sinusoid input signal is measured, a DC waveform at approximately 1.4 V is displayed (see right figure).

As in the above example, when Vm is 2 V, the rms value, Vrms, is approximately 1.4 V.

DC-RMS

This setting is used when you want to observe the rms values of both the DC and AC components of the input signal. Example If the rms value of a 2-Vpeak sinusoid input signal riding on top of a 1-V DC component is measured, a DC waveform at approximately 1.7 V is displayed (see right figure).

Acceleration Measurement

The Acceleration Module (with AAF) (701275 (ACCL/VOLT)) measures acceleration using the output signal from an acceleration sensor. Direction connection is possible to a built-in amplifier type acceleration sensor. (A charge output type acceleration sensor that does not have a built-in amplifier cannot be connected directly to the 701275 (ACCL/ VOLT). For details on how to connect acceleration sensors, see the SL1000 High-Speed Data Acquisition Unit User’s Manual (IM 720120-01E).)

Note

The 701275 (ACCL/VOLT) can also measure voltage.

Current Supply to Acceleration Sensors

The 701275 (ACCL/VOLT) can supply 4 mA of current to the acceleration sensor when measuring acceleration.

Note

If you supply current to the acceleration sensor before it is connected to the item under

measurement, the internal circuit of the acceleration sensor may be damaged. Be sure to

supply current after connecting the acceleration sensor.

Filter

If you set the bandwidth limit to Auto, the anti-aliasing filter (AAF) and low-pass filter are enabled depending on the sample rate to eliminate high-frequency noise from the input signal. Using the anti-aliasing filter when measuring voltage allows elimination of aliasing noise. For details on the bandwidth limit, see section 4.2.

Note

The filter is effective not only during acceleration measurement but also during voltage

measurement.

The deceleration curve is computed according to the following equation using the

elapsed time after the pulse input stops (Δt). Frequency (f) = 1/period (Δt) The decelerating prediction starts after a pulse period (T) of the pulse one period

before the pulse input stopped elapses after the pulse input stopped.

Stop Prediction

The function determines the stop point at a constant time after the pulse input stops,

and the frequency is set to 0. The time from the point when the pulse input stops to

Filter

Smoothing filter (moving average) The frequency module can display waveforms by taking the moving average of the data in realtime. The order of moving average can be set in terms of time in the range of 0.0 ms to 1 s (up to 25000th order). The order of moving average is equal to the specified time

dividedby40μs.

The smoothing filter has the following characteristics.

• Converts a waveform that changes in steps to a smooth waveform.

• Improves the resolution by reducing the measurement jitter. The resolution improves especially when measuring high frequencies or when expanding the display using the offset function. Consequently, highly accurate measurements can be made.

• Can be used on all measurement parameters of the frequency module.

Pulse Average

Measures the input pulse by dividing the pulse by the specified number of pulses (1 to 4096 pulses). The pulse average has the following characteristics.

• If pulse dropouts are present or pulse interval is fluctuating within a period, measurements can be made by eliminating the effects from the dropout or fluctuation (fluctuating component of the waveform used to measure the frequency or period).

• The measured result is displayed as a value per input pulse even when pulse average is used. Therefore, there is no need to perform scaling again.

• Can be used when measuring frequency, number of rotations, period, power supply frequency, pulse integration, and velocity.

Offset Function

The 701281 (FREQ) or 720281 (FREQ) allows you to set the center of observation (offset value) and expand the area around the offset value for close observation. It allows you to measure the fluctuation around a certain frequency. You can set an offset value up to 100 times the measuring range (500 kHz maximum).
