Frequency Lists
Versus Time
To demonstrates the relationship between the number of frequencies in a
frequency list and the time to hop through the list, program LIST_TME
makes continuous passes through a frequency list where the frequencies are
spaced 1 second apart.
Using the flowchart in Figure 4-1 as a guide, the steps of this program are:
1. Select the frequency list mode
[SOURce:]FREQuency[1]:MODE <mode>
2. Specify the frequency list
[SOURce:]LIST2:FREQuency <freq_list>
3. Set the list repetition count
[SOURce:]SWEep:COUNt <number>
4. Set the frequency advance source
TRIGger:SWEep:SOURce <source>
5. Set the frequency hop rate
[SOURce:]SWEep:TIME <number>
6. Set the output function
[SOURce:]FUNCtion[:SHAPe] <shape>
7. Set the number of waveform points (triangle wave)
[SOURce:]RAMP:POINts <number>
8. Set the signal amplitude
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <amplitude>
9. Place the AFG in the wait-for-arm state
INITiate[:IMMediate]
