Control Commands - HP 4934A Operating And Calibration Manual

Control Commands
Control commands change the 4934A's operation. Control commands emulate a
front-panel key; sending a command is comparable to pressing the corresponding
key. Another set of commands (query commands) retrieve results from the unit
(see
Query Commands,
page 7-8).
When the 4934A accepts a command it returns OK to the controller. Unknown
commands cause the unit to return ERR. Inappropriate commands are ignored.
