Sweeping Using
Start and Stop
Frequencies
The SMPLSWP1 program specifies a start frequency and a stop frequency
and continuously sweeps between 0 and 1 MHz. The program also queries
the start frequency, stop frequency, center frequency, and frequency span to
show the relationship between them.
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 that allows frequency sweeping
TRIGger[:STARt]:SOURce <source>
3. Select the frequency sweep mode
[SOURce:]FREQuency[1]:MODE <mode>
4. Set the start frequency
[SOURce:]FREQuency[1]:STARt <start_freq>
5. Set the stop frequency
[SOURce:]FREQuency[1]:STOP <stop_freq>
6. Set the number of sweeps
[SOURce:]SWEep:COUNt <number>
7. Set the output function
[SOURce:]FUNCtion[:SHAPe] <shape>
8. Set the signal amplitude
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <amplitude>
9. Place the AFG in the wait-for-arm state
INITiate[:IMMediate]
