Agilent Technologies 6843A, 6834B, 6814B Programming Output Transients, Step, PULSe, List, FIXed

4 - Programming Examples

Programming both the current and the voltage range in one program message unit can be done in any order and will not cause an error if the final combination specifies a valid current limit for the indicated range. If the commands

VOLTage:RANGe 300

CURRent 10;:VOLTage:RANGe 150

are sent, no error will be generated because the combined current limit and voltage range specified on the second line are within the output ratings of the above models.

Programming Output Transients

Output transients are used to:

υSynchronize output changes with a particular phase of the voltage waveform.

υSynchronize output changes with internal or external trigger signals.

υSimulate surge, sag, and dropout conditions with precise control of duration and phase.

υCreate complex, multi-level sequences of output changes.

υCreate output changes that have rapid or precise timing requirements.

The following ac source functions are subject to transient control:

AC output voltage

Frequency

Phase

Waveform shape

AC voltage slew rate

Frequency slew rate

DC output voltage (Agilent 6811B/6812B/6813B only)

Peak current limit (Agilent 6811B/6812B/6813B only)

The following transient modes can be generated:

STEP	Generates a single triggered output change.
PULSe	Generates an output change which returns to its original state after some time period.
LIST	Generates a sequence of output changes, each with an associated dwell time or paced by
	triggers.
FIXed	Turns off the transient functions, which means that only the IMMediate values are used as
	the data source for a particular function.
NOTE:	At *RST all functions are set to FIXed, which turns off the transient functions.
