Counter
The frequency counter measures signals in the frequency range from 100 mHz
to 200 MHz. The Counter connector on the rear panel is used by default to
receive the frequency counter input signal. The frequency meter works from
the start, unless the connector is set to an external clock input or clock output.
(1) Press the front panel Counter function key to enter the frequency counter
interface.
(2) Connect the signal to be tested to the Counter connector on the rear
panel.
(3) Press the HF Rejection softkey to toggle On or Off high frequency
rejection. High-frequency rejection can be used to filter high-frequency
factors when measuring low-frequency signals, improving measurement
accuracy. When measuring low frequency signals with a frequency less
than 1 kHz, turn on high frequency rejection to filter out high frequency
noise interference; turn off high frequency rejection when measuring high
frequency signals with frequencies greater than 1 kHz.
(4) The frequency, period and duty cycle can be viewed on the frequency
meter interface.
