Frequency and Period
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
(autorange) 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.
Advanced settings
Press Advanced to configure the advanced settings for the measurement.
AC Filter - Specifies which AC filter to use. The instrument uses three different AC filters that enable you
either to optimize low frequency accuracy or achieve faster AC settling following a change in input signal
amplitude.
