User Manual LW120
Using the Manual
Trigger
The manual trigger allows you to trigger or gate the LW120 directly
from the front panel. This button is active only when the generator
is placed in external trigger, or arm modes. The MAN TRIG button
has no affect on the instrument in other modes.
Using the SYNC
Output
For safety reasons, every time you turn the LW120 OFF and ON,
the SYNC output defaults to OFF. If you want to use the SYNC
output you must turn it on immediately after you power up the
generator.
When SYNC output generates two type of signals:
BIT
The BIT mode is recommended to be used in standard and
arbitrary modes only. The sync output generates a single sync
signal with every waveform period. As default, the sync signal is
positioned at the beginning of the waveform. You also have the
flexibility to control sync output parameters:
1. Position – Lets you place the sync bit at any point along the
waveform. Placement resolution is 4 points.
2. Width – Programs the width of the sync signal as percent of the
output period. Width resolution is 4 points.
LCOM
The LCOM (loop complete) option generates a sync
signal in sequenced mode only. The signal starts with the selected
segment and stops only after the sequence loop has completed.
Position and width parameters are ignore when you select the
LCOM type.
Use Figures 3-12, 3-13 and 3-14, along with the following

output type and adjust sync position and width.
