When the real-time waveform calculation (Model MR6000-01 only) is set to [On], a sampling rate of 200 MS/s cannot be selected. When the real-time save is set to [On], due to the combination of the number of channels to be used and save destinations, the maximum sampling rate that can be set varies as follows:

Maximum sampling rate that can be set

Number of channels to be used

1 channel to 2 channels 20 MS/s 10 MS/s 5 MS/s

Sampling rate

If the instrument plots non-existent waveforms (aliasing)

If a measured signal oscillates at a higher frequency compared to the specied sampling rate, the instrument may plot non-existent waveforms oscillating at a lower frequency than that of the actual signal when the signal frequency reaches a certain level. This phenomenon is called aliasing.

Measurement Method

Actual input signal

A sampling interval longer than the cycle of the input signal causes aliasing.

Sampling interval

To plot a sign wave that allows you to observe the peaks of the sine wave on the LCD without any aliasing, the instrument needs to sample the waveform at a minimum of 25 points per cycle.

To set the sampling rate automatically

Refer to “3.7 Measurement With the Auto-range setting” in Quick Start Manual.

Conguring Measurement Conditions

Update rate of each module

The data update rate is not allowed to exceed the maximum sampling rate of each module. The same data are measured until they get updated, causing the instrument to plot a stair-step waveform. In addition, even though the same signal is measured simultaneously, values may vary due to

differences in the sampling rate, frequency range, and frequency characteristics of modules.

Normal

Envelope Uses the envelope.

• Normal:

• Envelope:

• Values to be acquired using the envelope

A set of sampled data acquired using the envelope consists of two values: the maximum value and the minimum value. These values are taken from the measured values acquired at an over-sampling rate during

the recording interval set in [Sampling]. When shown on the screen, they are displayed as if they range in amplitude. When saved in an external storage device, the data of the maximum and minimum values are stored for a single instance of measurement.



The instrument records data at the specied sampling rate.

At the specied recording interval, the instrument records the maximum and minimum values among data sampled within each specied recording interval at an over-sampling rate* of 100 MS/s. Hence, even though a relatively longer recording interval is set, peaks of uctuations can be recorded without being missed.

Starting a measurement

Pressing the START key starts a measurement.

• Waveform data displayed on the screen is cleared once the measurement starts.

• You can also start the measurement by inputting signal into the external control terminal.

Refer to “10 Controlling the Instrument Externally” (p. 179).

Waveform display during measurement

In general, the waveforms are displayed after the specied recording length of data has been acquired. When the measurement is performed at a relatively slow speed, the waveforms are displayed while the data is being acquired.

However, even if a slow-speed range is set, the waveforms are displayed after the data of the

whole waveform has been acquired, depending on the overlay or magnication setting.

To save data automatically during measurement

Refer to “Saving waveform data automatically” (p. 68).

Stopping the measurement

Pressing the STOP key once stops the measurement after the waveforms of the specied recording

length have been acquired.

Pressing the STOP key twice stops the measurement immediately.

Converting Input Values (Scaling Function)

3.2 Converting Input Values (Scaling Function)

About the scaling function

The scaling function enables you to convert the measured voltage output from measuring devices such as sensors into physical quantities of measurement targets. Hereafter, the term “scale” refers to converting numerical values using the scaling function.

Gauge scales, scaled values (upper and lower limits of the vertical axis or voltage axis), and

measured values at trace cursors are expressed as scaled values in terms of the specied units.

You can scale the input values for each channel.

When using a strain gauge having a gauge factor of other than 2.0

Model U8969 Strain Unit measures outputs of the gauge supposing that the gauge factor stands at

2.0. When a strain gauge having a gauge factor of other than 2.0 is used, the gauge factor needs to be set as the conversion ratio. For example, if the gauge factor stands at 2.1, the conversion ratio will be 0.952 (≈ 2 / 2.1).

Example: To display data measured with a strain gauge (gauge factor: 2.1) as values in terms

of gees (G)

This conversion requires calculations based on both a gauge factor and a conversion ratio that converts data into physical quantities. In this case, specify the product of the conversion ratios of the gauge factor and the scaling ratio as the conversion ratio.

Where the conversion ratio of the gauge factor is 0.952, and the conversion ratio to convert data into physical quantities is 0.001442*. Conversion ratio = 0.952 × 0.001442 = 0.0013728

Advanced Functions

Type [0.0013728] as the conversion ratio.

*: To convert values measured with the strain gauge into physical quantities, calculate the conversion ratio

based on Young’s modulus or Poisson’s ratio of a measurement object. The conversion method varies depending on the conditions in which the strain gauge is used.

• Measured values are acquired based on the following: the interval between the times when measured waveform exceeds or falls below the threshold value, and the number of times when the waveform exceeds or falls below the threshold value.

• The upper and lower limits of the threshold value and the increment in the threshold value vary depending on the input voltage setting.

To prevent measurement errors due to noise, the hysteresis width that is approximately 3% of the input voltage is tolerated for the threshold. (When [Input voltage] is set to [±10 V], it stands at approximately ±0.3 V.)

Specify a threshold allowing for tolerance exceeding the hysteresis width relative to a peak voltage.

• The operation may be automatically restricted or the magnication may be changed if there is a risk that saving data cannot be completed in time during the real-time save.

After the measurement has been complete, execute [Execute], which is accessible by

proceeding in the following order:

> [Calculation] > [Numeric calculation]

Maximum recording time

• When the real-time save is set to [On], the maximum recording time is determined based on the recording interval, the remaining capacity of the storage device, and the number of channels used.

• When the sampling rate is set to a slow rate, the recording time is set to a long term (1 year or more) depending on a condition. The operation cannot be guaranteed because the warranty period or product life may disturb it.

• When the external sampling is used, the maximum recording time is calculated assuming a recording interval of 10 Ms/s.

Refer to “Maximum recording time when the real-time save is on (reference)” (p. 193).

Measured data

When recording waveforms with the real-time save set to [On], measured waveform data (.MEM or .REC) is directly saved to a storage device. If the le size is large, the le is automatically divided into several les each of which has 512 MB and then saved.

Deleting and saving les when data is saved in real time

• If the capacity of the storage device becomes full while les are being stored, the instrument deletes the waveform les created after the measurement has started beginning from the oldest automatically, securing free space in the storage device. However, when free space in a storage device is less than the sum of the created le size and 512 MB before starting a measurement, the instrument cannot overwrite any new les over the older les. Use a storage device with as much free space as possible.

• Waveform les saved in the past are not deleted.

• When [Method] is set to [Delete], the recording length can be set to 10000 days at a maximum;

however, the data that is retained after the measurement has stopped limited to a free space size of a storage device at the start of recording (recording time of the normal saving).

Allows you to enter the lter in terms of the number of samples. Only after the window-trigger condition continues to be satised during the specied period, the analog trigger is generated. Setting this option prevents the instrument from triggering unintentionally due to noise.

Allows you to enter the lter in terms of milliseconds when the envelope is used.
