Trigger System
The Trigger system, consisting of Trigger In and Trigger Out functions, provides the ability to
synchronize sequencer arbitrary waveforms. In addition, the Trigger Out function provides the
ability to generate trigger signal, if power supply output state or voltage / current programming
value has changed.
5.2.1
Trigger Initialize
Trigger In initialization is required to activate Trigger In function. The activation is available via the
Front Panel (refer to section 1.8) or the communication command INITiate[:IMMediate].
If continuous re-initialization is required, activate the system to be able to receive Trigger In signal
continuously via the Front Panel (refer to section 1.8) or the communication command
INITiate:CONTinuous <Bool>. Continuous re-initialization allows immediate triggering, thus
preventing the need for re-initialization.
5.2.2
Trigger In
Trigger In function triggers an execution of a sequence (LIST or WAVE) loaded into an active
memory cell.
There are three available triggers in the sources:
•
External trigger (rear panel DB26 J1.22) – Positive edge triggered pulse.
•
Front Panel trigger - Current or Voltage encoder press. Active only when power supply
output is ON and the display shows the measured voltage and current.
•
Communications trigger - *TRG or TRIG command (refer to sections 4.14 & 4.15.11).
Trigger In signal source selection is available via the Front Panel menu (refer to section 1.8) or via
the communication command TRIGger:SOURce <DSC>. BUS represents front panel or
communication command; EXT represents external trigger (Rear Panel DB26 J1.22).
