Triggering the AFG
Arming the AFG places the device in the Wait-for-Trigger state (Figure 5-1).
When a trigger occurs, the AFG digital-to-analog converter (DAC) outputs one
waveform amplitude point.
The information in this section covers the commands and programming
sequence used to trigger the AFG when outputting fixed frequency waveforms.
Triggering
Commands
The commands which trigger the AFG allow you to specify the following:
– the (start) trigger source
– the slope of an external (start) trigger signal
– the stop trigger source
– the slope of an external stop trigger signal
– the sample gating source
– the polarity of an external gating signal
– to enable sample gating
The triggering commands include:
TRIGger
[:STARt|SEQuence[1]]
:COUNt <
number>
:GATE
:POLarity <
polarity>
:SOURce <
source>
:STATe <
state>
[:IMMediate]
:SLOPe <
edge>
:SOURce <
source>
:STOP|SEQuence2
[:IMMediate]
:SLOPe <
edge>
:SOURce <
source>
Note The trigger count (TRIGger[:STARt]:COUNt) is always equal to the number
of amplitude points in the current waveform, multiplied by the number of
waveform cycles. This value is not programmable (other than 9.91E37), but
is included for SCPI compatibility purposes only.
