Specifying a
Frequency List
The LIST1 program shows the basic steps involved in setting up and
“hopping” through a frequency list. The program also shows how to query
the number of frequencies in the list.
Using the flowchart in Figure 4-1 as a guide, the steps of this program are:
1. Select the 42.9 MHz reference oscillator
[SOURce:]ROSCillator:SOURce <source>
2. Select the frequency generator which allows frequency lists
(hopping)
TRIGger[:STARt]:SOURce <source>
3. Select the frequency list mode
[SOURce:]FREQuency[1]:MODE <mode>
4. Specify the frequency list
[SOURce:]LIST2:FREQuency <freq_list>
5. Set the output function
[SOURce:]FUNCtion[:SHAPe] <shape>
6. Set the signal amplitude
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <amplitude>
7. Place the AFG in the wait-for-arm state
INITiate[:IMMediate]
