Assigning the
Source For The
SYNC Output
Using The Instrument 3-14
(ON).
For safety reasons, the SYNC output default setting is OFF. Disable
or enable the SYNC output using the following command:
OUTPut:SYNC {OFF | ON}
When the SYNC output state is programmed to ON, the SYNC
output connector generates signals which are triggered by signals
selected using the SYNC:SOUR command. In the OFF position, the
SYNC connector has no output. It is connected electrically to the
internal circuitry at all times. Ensure that voltage is not applied to the
SYNC at any time. The default SYNC position is the 6th point from
the end of the waveform. The position of the SYNC signal can be
programmed using the OUTPUT:SYNC:POS:POIN command.
The query:
OUTPut:SYNC?
queries the state of the SYNC OUTPUT and returns "0" (OFF) or "1"
(ON).
The SYNC output, when enabled, can be triggered by signals coming
from a number of sources. Use the following command to select the
source for validating the SYNC output:
OUTPut:SYNC:SOURce {BIT | LCOMplete | SSYNc |
HCLock}
BITGenerates a sync signal every time the segment is output

in User mode as well as in Sequenced mode.
The sync position along the waveform can be
programmed using the
OUTPUT:SYNC:POS:POIN command. POIN is
used to set both the TRIGger point and the
SYNC point. The BIT signal is recommended
for use in countinuous mode.
Generates a sync signal in SEQuence
mode only once when the selected segment
appears for the first time in the sequence. The
identity of the segment can be programmed
using the TRAC:SEL command. The sync
position along the selected waveform can be
programmed using the
OUTPUT:SYNC:POS:POIN command. The
LCOM signal is recommended for use in
