Bandwidth (Bandwidth)
You can specify a bandwidth limit for each module. You can use bandwidth limits to observe input signal
waveforms with their noise components removed.
Normal Bandwidth Limits
You can remove high-frequency components from the input signal. The bandwidth limits vary as shown below
depending on the input module.

2 When measuring voltage. Auto cannot be selected on the 701261.
3 Full cannot be selected when Preset is set to AC100V or AC200V.
For example, on the 701251 (HS1M16), you can set the bandwidth limit to 400 Hz, 4 kHz, or 40 kHz. The
frequency characteristics for the different bandwidth limits are shown below. If you select Full, the module’s
maximum bandwidth is used.

Bandwidth Limitation on the 701262 (UNIVERSAL (AAF)) and the 701275 (ACCL/VOLT)
When you are measuring voltage using the 701262 (UNIVERSAL (AAF)) or when you are using the 701275
(ACCL/VOLT) and the bandwidth is set to Auto, the anti-aliasing and low-pass filter settings vary as shown below
depending on the sample rate.

For example, when the sample rate is between 100 kS/s and 50 kS/s, the cutoff frequency of the anti-aliasing
filter is 40% of the sample rate.
