You need to configure appropriate paremeters for the counter.
1. TrigSens
Set the trigger sensitivity of the measurement system. The default is 50% and
the range available is from 0% to 100%.
Press TrigSens. Use the numeric keyboard to input the desired value and
select the unit “%” from the pop-up menu.
2. TrigLevel
Set the trigger level of the measurement system. The system triggers and
gets the measurement readings when the input signal reaches the specified
trigger level. The default is 0V and the range available is from -2.5V to 2.5V.
Press TrigLevel. Use the numeric keyboard to input the desired value and
select the desired unit (V or mV) from the pop-up menu.
3. Impedance
Set the input impedance to “50Ω” or “HighZ” and the default is “HighZ”.
4. Coupling
Set the coupling mode of the input signal to “AC” or “DC” and the default is
“AC”.
5. Atten
Set the attenuation coefficient of the input signal to “X1” or “X10”.
6. HFReject
High-frequency reject can be used to filter out the high-frequency
components and improve the measurement accuracy in low-frequency signal
measurement.
Press HFReject to enable or disable the high-frequency reject function.
