Calibration (10x1000 Pulse Option)
The 10x1000 Pulse Option calibration involves calibrating the 10 Amp peak pulse
current, the Auxiliary Power Source and the several available loads. Please refer to
Figure 13-39 which shows the 10x1000 Pulse Option Calibration window. A short
circuit (Cal Fixture) is placed across the device socket terminals for calibration.

Confirm, by checking both boxes, that the Self-Test has been run and the
Calibration Fixture is installed.

Auxiliary Power Source
o
Enter the desired Bias Voltage (usually the Bias voltage being used
the HldOvr tests)
o
Click the “CAL: AUX SRC” button

The Aux Src voltage is confirmed through a 200 Ohm 0.1%
resistor on the 10x1000 board both in the Positive and
Negative directions.

The offset corrections are displayed.

10 Amp Peak Pulse Current
o
Click the “CAL 10x1000” button

The peak current is measured and, if necessary, corrected,
automatically to 10.2 Amps minimum.

The peak current is displayed.

Loads
o
Select which load to calibrate and click the “CAL xxxmA” button.
o
The selected load is driven with the corrected Auxiliary Source Bias
Voltage and the current is displayed.
Click the “Repeat” button in the
lower left of the PCW main window and then slowly adjust the correct
potentiometer until the load current is correct.
o
The load current is displayed.

These calibration factors are stored in memory and will be used until the
5000 Series Test System is powered down. To save these calibration factors
for use after the system is powered down, click the “Save / Exit” button.
