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 4.13 & 4.14.11).
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).
5.2.3
Trigger Out
Trigger Out function is an active high output signal located on the Rear Panel DB26 J1.23. There
are three available trigger out modes: OFF, FSTR, TRIG. Each mode depends on the setting of
current and/or voltage programming mode (refer to [SOURce]:CURRent:MODE <DSC> and
[SOURce]:VOLTage:MODE <DSC> commands).
Programming mode NONE (for Current and Voltage mode, both set to NONE)
•
OFF Mode – No trigger output signal.
•
TRIG Mode – Trigger is generated if output state changes.
•
FSTR Mode – Trigger is generated in case of output state change (ON/OFF), voltage
programming value update or current programming value update.
Programming mode WAVE or LIST (for Current or Voltage mode)
•
OFF Mode – No trigger output signal.
•
TRIG Mode – Trigger is generated if the LIST or WAVE sequence is completed.
•
FSTR Mode – Trigger is generated every step (after completion).
To enable Trigger Out signal functionality, refer to the Front Panel menu operation (refer to section
1.8) or to the communication command OUTPut:TTLTrg:MODE <DSC>.
5.2.4
Trigger Delay
Trigger Delay function provides the ability to delay the LIST or WAVE sequence execution following
a Trigger In. Trigger delay can be set via the Front Panel menu (refer to section 1.8) or the
communication command TRIGger:DELay <NRf+>.
To override trigger delay, use the TRIGger[:IMMediate] command. TRIGger[:IMMediate] disregards
trigger delay setting. Trigger Delay function range is 0 ~ 10 seconds, in steps of 1 mSec.
