Menu Description
Coupling
Press the Coupling softkey to select the coupling type.
– DC
DC coupling allows both AC and DC input signals to pass through to the digital analyzer and to be measured down to
0 Hz. This setting should be selected when making DC voltage measurements.
– AC
AC coupling blocks the DC component of the input signal. This setting should be selected when you need to measure
only the AC component of a signal. For example, when you are making rms or peak-to-peak voltage measurement.
Sample Size
Press the Sample Size softkey to select the sample size. The sample size is the number of data points acquired for the
measurement. The higher the sample size, the higher the accuracy of the measurement result.
