Remarks:

Sets the control type of the external trigger input used when the trigger

source is set to EXTTTL in READOUT or POWER vs. TIME mode.

Select channel 1, 2 or 1&2. Selecting 1&2 allows both channels to trigger

together on the same conditions without having to set up two sets of trig

ger data. If external trigger is used on both trigger channels (1 and 2) the

same TTL edge MUST be used on both channels.

Query:

TRGXTTL? <c>

Returned

String:

TRGXTTL <c>,<type>

The TRG type commands return the trigger state of the selected channel if

the channel is ON. This depends on the settings of the “link triggers” flag

and the current mode of the sensor on the selected channel. If the channel

is OFF, the stored trigger state of the channel is returned.

(Analog Input 2). This will calibrate the units to read zero volts on this BNC.

During this operation the connector should either not be connected to any-

thing, or should be connected to a 0 Volt source. A settling time must be al

lowed after this command before reading any other commands.
