Reset the instrument to its default settings.
Set the source function to current and turn on source readback.
Set the digitize function to voltage and the digitize voltage range to 20 V.
Set the digitizer sample rate to 25000 readings per second.
Set up a pulse train with a bias level of -1 A and a pulse level of -3 A. Set the train to create three pulses with
a pulse length of 10 ms and an off time of 90 ms. Set the pulse voltage limit and the bias voltage limit to 15 V.
Start the pulse train.

•
Voltage: -100 V to 100 V
Details
This command manually selects the measurement range for the specified source.
If you select a specific source range, the range must be large enough to source the value. If not, an
overrange condition can occur.
If an overrange condition occurs, an event is displayed and the change to the setting is ignored.
The fixed current source ranges are 1 µA, 10 µA, 100 µA, 1 mA, 10 mA, 100 mA, 1 A, 4 A, 5 A, 7 A,
and 10 A. Note that if the 10 A range is selected, the maximum source output level is 7.35 A unless
pulsing is active.
The fixed voltage source ranges are 200 mV, 2 V, 7 V, 10 V, 20 V, and 100 V.
When you read this value, the instrument returns the positive full-scale value that the instrument is
presently using.
