Function
Bandwidth
The following frequency bandwidth limit can be set on each input module. Each channel is set
individually.
No bandwidth limit is set if “FULL” is selected.
High-Speed Isolation Module and High-Speed Module (Low pass filter)
Full, 500 kHz, 50 kHz, 5 kHz, 500 Hz
High-Speed Module (Low pass filter)
Full, 5 MHz, 500 kHz
High-Resolution, High-Voltage, Isolation/High-Resolution, Isolation Module (Low
pass filter, anti-aliasing filter)
Full, Auto, 4 kHz, 400 Hz, 40 Hz
If a limit other than Full or Auto is selected, low pass filter is selected for the specified
frequency.
Selecting Auto automatically combines the anti-aliasing filter and low pass filter according to
the sample rate as shown below and limits the frequency bandwidth.
