Setting Measurement Conditions

To set the sampling rate automatically

Refer to “3.7 Measuring Signals With the Auto-range Setting” of Quick Start Manual.

Update rate of each module

The data refresh rate is not allowed to exceed the maximum sampling rate of each module.

The instrument measures the same data until the data gets updated, causing the instrument to plot

a stair-step waveform.

In addition, even though the instrument measures the same signal simultaneously, values may vary

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