The OUTPut command subsystem sets the source of output pulses for the specified
TTL Trigger line (TTLT0-TTLT7) and enables or disables the output.
Subsystem Syntax
OUTPut
:TTLT<n>:SOURce TRIGger | SAMPle | BOTH
:TTLT<n>:SOURce?
:TTLT<n>[:STATe]
ON | 1 | OFF | 0
:TTLT<n>[:STATe]?
:TTLT<n>:SOURce
OUTPut:TTLT<n>:SOURce TRIG | SAMP | BOTH sets the source of output
pulses for the specified TTL Trigger line.
Comments
•
<n> can have the value 0 through 7 (TTLT0 - TTLT7).
•
The Digitizer allows separate control of the trigger signal and the sample
signal output to the TTL trigger lines. Each can output to only a single line;
however, they can both output onto the same line when the BOTH parameter is
used. When BOTH is used, no other lines can be enabled.
•
Output pulses will not be sent until the TTL trigger line state is set to ON.
•
Resource conflicts will occur if either the trigger or sample source is already
using a TTL line you attempt to enable. The trigger source will be set to
IMMediate if it is the conflict. The sample source will be set to TIMer if it is
the conflict. A “Settings Conflict” error will occur.
•
Setting the trigger or sample source to a TTL trigger line that has its output
state ON will result in a “Settings Conflict” error and the output state will be
changed to OFF. The specified trigger line will be assigned to the sample or
trigger source.
•
Executable when initiated: No
•
Coupled Command: Yes
•
Reset (*RST) Condition: Source is SAMPle for all TTL lines
:TTLT<n>:SOURce?
OUTPut:TTLT<n>:SOURce? queries the specified TTL Trigger line (TTLT0-
TTLT7) to identify the source of output pulses. A response of “TRIG” indicates the
source is a trigger event, a “SAMP” indicates the source is a sample event and a
response of “BOTH” indicates the source is both a trigger event and a sample event.
