Arming and
Triggering a
Frequency List
Frequency lists are started and advanced using the same arming and
triggering commands used for sweeps. The LIST_STP program sets the
arm and list advance sources to BUS. Thus, the AFG is armed and
advanced through the frequency list using the GPIB group execute trigger
command TRIGGER 7.
Using the flowchart in Figure 4-1 on page 118 as a guide, the steps of this
program are:
1. Select the frequency generator which allows frequency lists
(hopping)
TRIGger[:STARt]:SOURce <source>
2. Select the frequency list mode
[SOURce:]FREQuency[1]:MODE <mode>
3. Set the frequency list
[SOURce:]LIST[2]:FREQuency <freq_list>
4. Set the source which starts the frequency list
ARM:SWEep:SOURce <source>
5. Set the source which advances the list to the next frequency
TRIGger:SWEep:SOURce <source>
6. Set the output function
[SOURce:]FUNCtion[:SHAPe] <shape>
7. Set the signal amplitude
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <amplitude>
8. Place the AFG in the wait-for-arm state
INITiate[:IMMediate]
