Section 7: TSP command reference Model 2657A High Power System SourceMeter® Instrument Reference Manual

7-36 2657A-901-01 Rev. B/December 2012

Details

Data for pulsed voltage measurements are stored in the reading buffer specified by the buffer input parameter.

This function configures a linear pulsed current sweep with a voltage measurement at each point. Measurements

are made at the end of the ton time.

The magnitude of the first pulse will be start amperes; the magnitude of the last pulse will be stop amperes.

The magnitude of each pulse in between will be step amperes larger than the previous pulse, where:

step = (stop - start) / (points - 1)

This function does not cause the specified smu to output a pulse train. It does check to see if all the pulse

dimensions can be achieved, and if they can, assigns the indicated tag or index to the pulse train.

Set up a pulsed sweep that will use System

SourceMeter

instrument channel A. The pulsed

sweep will start at 10 mA, end at 50 mA, and return to

a 0 mA bias level between pulses. Each pulsed step

will be on for 15 ms, and then at the bias level for

100 ms. The voltage limit will be 500 V during the

entire pulsed sweep. The pulse train will be

comprised of 20 pulsed steps and the pulse train will

be assigned a tag index of 3.
