ML24XXA NATIVE COMMANDS GPIB OPERATION

type: RISE FALL

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.

VZERO Zero the BNC input connector CALIBRATION

Syntax: VZERO

Remarks: Zeros the multipurpose BNC connector used for Volts per GHz connection (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.

ZERO Zero the selected sensor CALIBRATION

Syntax: ZERO <s>

s:A or B

Remarks: Zero out the noise from the selected sensor.
