The arming commands for continuous waveforms are uncoupled
commands. They are executed relative to other AFG commands in the
sequence of Figure 5-2.
Note 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.
Setting Arming
Sources
The EXT_ARM program shows how to select the source which arms the
AFG. The program selects the AFG’s “Start Arm In” BNC connector as the
arming source. When an arming signal is received, a 10 kHz, 1 Vpp square
wave is output.
The steps of this program are:
1. Select the FIXed frequency mode
[SOURce:]FREQuency[1]:MODE <mode>
2. Set the output frequency
[SOURce:]FREQuency[1][:CW | :FIXed] <frequency>
3. Set the output function
[SOURce:]FUNCtion[:SHAPe] <shape>
4. Set the signal amplitude
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <amplitude>
