Agilent E8462A Relay Multiplexer Command Reference 111
Parameters
Comments Command Not Supported. Attempting to change the TRIGger:SLOPe to anything
other than
NEG will generate an error.
TRIGger:SLOPe?
TRIGger:SLOPe? Is used to query the polarity of the output trigger. For the Agilent
E8462A, this query always returns NEG.
Example Query Trigger Slope
TRIG:SLOP?
Always returns NEG.
TRIGger:SOURce
TRIGger:SOURce <source> Specifies the trigger source to advance the channel list
during scanning.
Parameters
Comments
Enabling the Trigger Source: The TRIGger:SOURce command only selects the
trigger source. The
INITiate[:IMMediate] command enables the trigger source.
Using the
TRIGger Command: You can use TRIGger[:IMMediate] to advance the
scan when
TRIGger:SOURce BUS or TRIGger:SOURce HOLD is selected.
One Trigger Input Selected at a Time: Only one input (
ECLTrg0 or 1; TTLTrg0,
1, 2, 3, 4, 5, 6, or 7; or EXTernal) can be selected at one time. Enabling a different
trigger source will automatically disable the active input. For example, if
TTLTrg1
is the active input, and
TTLTrg4 is enabled, TTLTrg1 will become disabled and
TTLTrg4 will become the active input.
Using External Trigger Inputs: With
TRIGger:SOURce EXTernal selected, only
one switchbox at a time can use the external trigger input at the Agilent E1406A
"Trig In" port. The trigger input is assigned to the first switchbox that requested the
