OUTPut:TTLTrg<n>:SOURce
OUTPut:TTLTrg<n>:SOURce?
Sets or queries the waveform analyzer source for each VXI TTL trigger line. The
waveform analyzer drives the VXIbus trigger lines only when they are enabled
and a valid trigger event occurs. The available waveform analyzer sources are
as follows:
H ARM — a valid ARM event occurs which enables the TRIG:A circuit
H ATR — a valid trigger event from the TRIGger A subsystem
H BTR — a valid trigger event from the TRIGger B subsystem
H OPC — the signal indicating the active command is complete. It is derived
from the Operation Complete bit in the Standard Event Status Register.
H CALC — a true evaluation of the TRG function in a CALC expression has
occurred
Use the command OUTPut:TTLTrg<n> to enable each VXI TTLTrg line.
The waveform analyzer can simultaneously source and sense TTLTrg lines.
