A Sample Program for Setting Measurement Conditions
The following is a sample program for setting measurement conditions. The program is
given the file name setup.bas and stored on the sample program disk.
This program resets the Agilent 4294A, then makes the settings shown below, and finally
delivers the completion message when the settings are completed.
