Can open/short/load correction data be entered in the 4285A from an external PC over GPIB?

The 4285A does not have GPIB command to enter open/short/load compensation data transferred from an external PC. Alternatively, it is possible to perform open/short/load compensation with an external PC. This method can also be expanded to multi-channel compensation for a scanning measurement system.

A sample program is described in Application Note "Effective Impedance Measurement Using OPEN/SHORT/LOAD Correction" available from application notes list on the Keysight 4285A website. (Note: You need to translate the 4194A sample program into 4285A program using GPIB commands for the 4285A.)
