Configuration
Configure Current and Voltage Channels 7
7-17
Configure Filter
The anti-aliasing filter is located in the measuring channel. It is a prerequisite for the
correct analysis of Fast Fourier Transform (FFT) data. The default configuration is ON.
The anti-aliasing filter has a cut-off frequency of 1/10 of the sampling frequency. At half
the sampling frequency, no signal reaches the A/D converter.
Note
For broadband numerical measurements in lighting technology, set the
filter to OFF.
If measurements at high frequency are made without filter, it is not possible
to correctly analyze the signals, due to aliasing. Please refer to the section,
“Undersampling and Aliasing”, in Chapter 7.
1. Move the cursor to the value in column Level and press Enter.
The options AC and DC are displayed.
2. Select the desired value and press Enter.
The entered value is shown in column Level.
3. If you wish to configure all three current channels in this way, press Set All.
4. Save the configuration settings by pressing the SAVE function key.

Note
To configure the voltage channels, proceed as described for the current
channels.
1. Press function key U/I.
