7.6.9 How to Generate a Signal in List or Sweep Mode
This section shows you how to configure a varying RF output signal for both, the list
and sweep modes.
To configure the frequency sweep signal
1. In the status bar, enter "Freq > 6 GHz" and "Lev > -25 dBm".
2. Select "RF" > "Sweep/List" > "RF Frequency Sweep"
3. Select "Mode > Auto".
4. Select "Spacing > Linear".
5. Set "Dwell Time > 15.0 ms".
6. In the "Frequency Range" tab, set "Start Freq > 200 MHz" and "Stop Freq > 600
MHz".
(Alternatively you can set "Center Freq > 400 MHz" and "Span > 400 MHz".)
7. Set the step width "Step Lin > 10 MHz" and "Dwell Time > 10.0 ms".
8. In the "Advanced" tab, trigger the sweep "Auto".
9. In the "General" tab, select "State > On".
Example: Fast changing frequency and level settings in list mode
The following example shows you how to generate an amplitude modulated RF signal
based on list mode data.
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 processing mode.
5. Execute "Learn List Mode Data" if necessary.
6. Activate list mode.
To configure amplitude modulation and switch RF on
1. Press PRESET to start from an initial state.
2. Select "RF" > "Analog Modulation" > "Amplitude Modulation > On".
3. Select "RF > On" to activate RF signal generation.
