To create list mode data
1. Select "RF" > "Sweep/List" > "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.
● In remote control mode, you can query:

Analog Modulations
The R&S
SMBV100B supports AM (amplitude modulation), FM (frequency modula-
tion),
Φ
M (phase modulation (PhiM)), and also PULM (pulse modulation). It generates
low frequency signals (LF) as sine, triangle, trapezoidal or square (pulse) waveform,
that can be output and further processed by a downstream instrument.
