Initiating Waveforms

Arming the AFG

Arming Commands

Chapter 5
After the AFG has been configured to output the desired waveform, the
AFG is set to the Wait-for-Arm state with the command:
INITiate[:IMMediate]
INITiate is an uncoupled command and is generally the last command
executed before a waveform is output:
SUB Sine_wave
Sine_wave: !Subprogram which outputs a sine wave
COM @Afg
OUTPUT @Afg;"SOUR:FREQ1:FIX 1E3;";
OUTPUT @Afg;":SOUR:FUNC:SHAP SIN;";
OUTPUT @Afg;":SOUR:VOLT:LEV:IMM:AMPL 5 V"
OUTPUT @Afg;"INIT:IMM"
SUBEND
If INITiate[:IMMediate]
Error -213, "Init ignored" is generated.
In order for the AFG to accept trigger signals which output the amplitude
points of the waveform, the AFG must be armed. The information in this
section covers the commands and programming sequence used to arm the
AFG for fixed frequency waveform generation.
The commands which arm the AFG allow you to specify the following:
the arm source
–
the slope of an external arm signal
–
the number of arms per
–
the number of waveform cycles per arm
–
The arming commands include:
