Description
Selects the source characteristic of the 3152B SYNC output.
Parameters
Name
Type
Default
Description
BIT
Discrete
BIT
Outputs a narrow sync pulse at a selected position
along a standard or arbitrary waveform. For modulated
modes, the sync output is automatically used as a
marker. The fixed width of the sync pulse in this mode is
4 points in modern mode and 2 points in legacy mode.
Use PULSe mode instead of BIT if the width of the
pulse needs to be changed.
LCOMplete
Discrete
The LCOM sync pulse starts at the beginning of the
selected segment of a sequence and ends at the end of
the sequence. You may change the start position within
the segment by using the outp:sync:pos command. You
may change the segment using the trace:sel command.
In either case the LCOM pulse will start at the specified
position but will always end at the end of the sequence.
SSYNc
Discrete
Similar to the bit option except that it for triggered or
gated modes it eliminates the
±
1 clock jitter between the
trigger and the output signal by using a special circuit
that synchronizes the sync output to the triggered
signal.
HCLock
Discrete
Generates a sync output pulse that has a 50% duty
cycle regardless of the period of the output waveform
PULSe
Discrete
Similar to the bit option except that the width of the sync
pulse in 4 point increments from 4 to n-8 points (2 point
increments from 2 to n-4 in legacy mode). The position
of the pulse is programmed using the outp:sync:pos
command and the width is programmed using the
outp:sync:wid command.
ZEROcross
Discrete
Zero crossing is a special mode where the sync signal
remains low as long as the output waveform level is
negative (below 0 V) and changes to high when the
output level becomes positive (above 0 V).
Response
The 3152B returns BIT, LCOM, SSYN, HCL, PULS, or ZERO depending on the selected SYNC source.
