Frequency and Period
The Frequency and Period measurement option will only be available when Scan is selected as the acquisition
mode.
This section describes how to configure the selected channel for frequency and period measurements from the front
panel.
1. Connect an AC source to the module's screw terminals.
2. Press [Channel] > Measure, and select FREQ or PERIOD from the selection menu.
3. Press Range and use the knob or the front panel arrow keys to specify the measurement range. Auto (autor-
ange) automatically selects the range for the measurement based on the input. Autoranging is convenient, but it
results in slower measurements than using a manual range. Autoranging goes up a range at 120% of the
present range, and down a range below 10% of the present range.
4. Press Gate Time to specify the measurement's aperture (integration time) as 1 ms, 10 ms, 100 ms, or 1 s.
