HP 70428A Microwave Source program example
This program example first resets the instrument and then sets it up to output
a 2.4 GHz signal at +10 dBm with a 100 MHz phase-lock-loop bandwidth of
53 Hz and a 600 MHz bandwidth of 4 KHz. A short routine at the end of the
program checks and displays any HP 70428A errors.
Comments for the program follow the program listing.
