General workflow
Since any change of the hardware settings or list entries can affect the RF signal char-
acteristics directly, we recommend that you proceed as follows:
1. Configure the modulation settings.
Activate the RF signal.
2. Wait until the hardware settings have settled.
3. Create a list file.
4. Configure the list mode.
5. Activate list mode.
To configure amplitude modulation and switch RF on
1. Press [Preset] to start from an initial state.
2. Select "Modulation" > "Amplitude Modulation > On".
3. Select "Level" > "RF ON" to activate RF signal generation.
To create list mode data
1. Select "Sweep" > "List Mode".
2. In the "List Mode Data" tab, select "List Mode Data > New"
3. Enter the filename ListMode_Test for the data list and confirm with "Ok".
The instrument creates a file and stores it in the /var/user/ directory.
4. Select "Edit List Mode Data".
5. Enter the first values "Frequency > 2", "Power > 0" and "Dwell > 2".
6. Enter further frequency, power and dwell time values in the same way.
7. Select "Save" and close the dialog.
To configure the list mode and start signal generation
1. In the "General" tab, select "List Mode > Auto".
2. Select "Dwell Time Mode > From List".
3. Switch state to "On".
4. Select "General > State > On".
The instrument continuously generates an amplitude-modulated RF signal whose
frequency and level values change according to the dwell times, as defined in the
list.
With active list mode, the generator displays no frequency and level values in the
status bar, but you can check the following parameters.
● In the list mode dialog, the current index indicates the steps of the signal gener-
ation.
