SCPI Commands for Digital Interfaces

Triggering Triggers are event-driven signals that instruct power supplies to change their output. Commands Triggering provides a method to control changes in the power supply’s output and to

program several power supplies to react at the same time. Triggering is useful in manufacturing processes where power requirements change as the machinery performs different operations.

CAUTION

Setpoint limits do not apply to triggered setpoints.

To program triggers:

1.Configure the desired output levels as a result of a trigger.

VOLTage:TRIGgered {<voltage>MAXMINDEF} CURRent:TRIGgered {<current>MAXMINDEF} POWer:TRIGgered {<power>MAXMINDEF}

The user can choose to set all or any one of voltage, current, and power triggered levels.

DEF (DEFault) means that when a trigger is received, no change will occur.

2.Specify a trigger signal source.

TRIGger:SOURce {BUSEXTIMMNONE} Where:

•BUS means the trigger source is the IEEE 488.1 GET or “*TRG”

•EXT means the source is the external trigger line

•IMM means the trigger source is the SCPI command INIT:IMM

•NONE means triggering is disabled. See , p. 109.

Auto Auto Sequencing allows users to program a sequence of steps. Each step has the Sequencing properties of voltage, current, power limits, and OVP limit. The steps are either

programmed to run for a predetermined length of time or are programmed to pause and wait for a trigger.

CAUTION

Setpoint limits do not apply to auto sequence programmed setpoints.

Programmed sequences can run one time only, or repeatedly up to 9999 times or infinitely. You can store up to 10 sequences of 99 steps each. The duration of each step may range from a minimum of 10 milliseconds to a maximum of 99 hours.
