FSK Command Reference
Detailed information on the commands introduced in this chapter can be
found in Chapter 8, “Command Reference”. The commands in this chapter
are shown in their entirety (optional headers included) to help you locate
them in the reference.
Sweeping and Frequency Lists
The AFG offers linear frequency sweeping of standard waveforms (that is,
sine, square, triangle, ramp) and arbitrary waveforms from 0.0 Hz to
10.73741824 MHz, and logarithmic sweeping of standard and arbitrary
waveforms from 0.01 Hz to 10.73741824 MHz.
The AFG can also “frequency hop” — where the AFG outputs a sequence
of discrete frequencies from a pre-defined list. Up to 256 frequencies from
0.0 Hz to 10.73741824 MHz can be specified in a single list, and the AFG
can sequence through the list at up to 800 frequencies per second.
Sweeps and frequency lists are programmed with the same commands. The
command subsystems covered in this section include:
• [SOURce:]ROSCillator
• TRIGger
• [SOURce:]FREQuency[1]
–
Sweep mode and related commands
– Frequency list mode and related commands
• [SOURce:]SWEep
• ARM:SWEep
The following programs show how to perform sweeps and frequency lists.
