Description/Defaul t
– BUS: the trigger source is the group execute trigger <GET> bus
command, a *TRG common command or the
TRIGGER:IMMediate SCPI command.
– EXTernal: the trigger source is the trigger input in the back panel.
– HOLD: triggering is suspended. The only way to trigger the power
meter is to use TRIGger:IMMediate.
– IMMediate: the trigger system is always true. If
INITiate:CONTinuous is ON the power meter is continually
triggering free (free run mode). If an INITiate:IMMediate
command is sent a measurement is triggered then the power meter
returns to the idle state.
– INTernal: either INT1 (channel A) or INT2 (channel B).
TRIG:SOUR IMM
This command configures channel A for
immediate triggering.
