3151 And 3151A User Manual
Using The Instrument 3-15
Sequence mode.
SSYNc
Generates a sync signal at intervals that are
synchronized with the internal clock generator.
This option is useful to minimize jitter when
using an oscilloscope. The SSYNc signal is
recommended for use in Triggered mode.
HCLock
Generates a trigger signal at intervals equal to half
of the period of the sample clock. This option is
useful for synchronizing two-point waveforms
on an oscilloscope (sine and square waveforms
above 10 MHz).
The query:
OUTPut:SYNC:SOURce?
queries the validating signal source for the SYNC output and returns
BIT, LCOM, SSYN or HCL.
Selecting the SYNC
Position
The SYNC output can be programmed to output the SYNC signal at
any point along the output waveform. This function is available in
USER or SEQ modes only. Use the following command to select the
SYNC output position:
OUTPut:SYNC:POSition:POINt <value>
The SYNC position can be selected from point 0 to the last point of
the active waveform. SYNC position has to be programmed for each
segment. The default SYNC position is 6 points from the end of the
segment.
The query:
OUTPut:SYNC:POSition:POINt?
queries the output SYNC position and returns an integer value.
