90 Keysight E3633A and E3634A Service Guide
An Example Program of Excel 97 for Calibration
This section contains an Excel Macros (Visual Basic® for Applications) program
for calibration over the GPIB interface. This program makes software adjustments
to the E3633A power supply using a current shunt and a digital multimeter which
is connected to the controller. In this program a 0.001 ohm current shunt is used.
Be sure to change the value of the variable “shunt” to the value of the current
shunt used and the GPIB address for the power supply and the digital voltmeter.
