Selected event When is the SYNC signal generated
Output Settle
A SYNC is produced when the output of the Power
Module settles to within 2% of Vmax or Imax from the
programmed Vset or Iset.
A new SYNC signal is generated following any
commanded change of the Power Module’s output, be it a
new Vset or Iset value, a ramp operation or an output
on/off state change.
You can use the SYNC signal to synchronize external
hardware to changes in the Power Module’s output.
No Operation
The power module will never generate a SYNC signal.
Use this selection when you wish the SYNC output to be
associated with a specific power module.

Not defined – reserved for future expansion.
new SET value
The Power Module generates a SYNC whenever a new
Vset or Iset value is programmed (and NOT when the
output actually changes).
You can use the SYNC signal to synchronize external
hardware to expected
changes in the Power Module’s
output (an advanced trigger or “pre-trigger”).
Trigger
The Power Module generates a SYNC whenever it
receives a trigger (either hardware or software trigger).
Using this SYNC generation mode enables the XMP 2600
to generate a hardware signal in response to a software
event.
How to select the event that generate a SYNC
To select the event that will cause the power module to generate a SYNC proceed as
follows:
Select the power module to program (see: first operation steps chapter
for details).
Select the SYNC parameter (use the up / down selection keys) and
enter programming mode (press the SET key) or enter programming
mode and then select the SYNC parameter (see: Programming power
module parameters in the basic operation chapter).
Use the UP / DOWN selection keys to select the desired event that will
cause the power module to generate a SYNC.
Proceed to program other power module parameters or exit
programming mode by pressing the SET key.
Output ramping
What is
output
ramping?
Output ramping is a feature of the XMP’s Power Modules that enable them to
produce a gradual linear smooth change in their output. The change in a Power
Module’s output can be either a voltage change or a current change.
