Frequency Measurement

Ranges
1.00 Hz to 109.99 Hz
110.0 Hz to 1099.9 Hz
1.100 kHz to 10.999 kHz
11.00 kHz to 50.00 kHz
Minimum Amplitude for Frequency Measurement (square wave):
<1 kHz: 300 mV p-p
1 kHz to 30 kHz: 1.4 V p-p
>30 kHz: 2.8V p-p
Maximum input:
<1 kHz: 300V rms
>1 kHz: 30V rms
Input Impedance: 5 M
For frequency measurement less than 109.99 Hz, specifications apply for signals with a slew rate greater than 5
volt/millisecond.
