Using The Instrument 3-11
Assigning the Validating
Source For TTLTRG
The TTLTRG signals, when enabled and placed on the backplane,
can be asserted with signals coming from a number of sources.
Use the following command to assign the signal source for the
active TTLTRG line:
OUTPut:TRIGger:SOURce {BIT | LCOMplete |
INTernal | EXTernal}
BIT
Generates a trigger signal at any point in
the waveform. The trigger position within
the waveform can be programmed using
the OUTPUT:SYNC:POS:POIN command.
This command is used to set both the
TRIGger point and the SYNC point.
LCOMplete
Generates a trigger signal in SEQuence
mode only once when the selected
segment appears for the first time.
INTernal
Generates a trigger signal at intervals set
by the internal trigger generator .
EXTernal
Generates a trigger signal every time a
trigger is applied to the front panel TRIG IN
connector.
The query:
OUTPut:TRIGger:SOURce?
queries the validating signal source for the backplane TTLTRG<n>
lines and returns BIT, LCOM, INT or EXT.
Enabling the Main
Output
For safety reasons, the main output default setting is OFF. Disable
or enable the main output using the following command:
OUTPut {OFF | ON}
When the main output state is programmed to ON, the output
connector is connected to the output amplifier through a 50
S
resistor. In the OFF position, the output connector is disconnected
from the output amplifier by means of a mechanical relay. Ensure
that voltage is not applied to the main output connector when the
Model 3152 output state is programmed to ON.
The query:
OUTPut?
queries the state of the main output and returns "0" (OFF) or "1"
(ON).
