Chapter Six: SPECTRUM ANALYSER CONTROL
This chapter described how to control Spectrum Analyser from the server
machine. Sgpib programming commands and some useful Spectrum Analyser
programming commands will be described.
6.1 HP 8591 EM Spectrum Analyser Programming Commands
Because there are hundreds of programming commands, author only lists some commands which
used in this project. See total Programming Commands in 8590 Series Programming Compatibility
Guide (2001).

CF (Center Frequency): Specifies center frequency.

CONTS (Continuous Sweep): Sets the spectrum analyzer to the continuous sweep mode.

FA (Start Frequency): Specifies the start frequency.

FB (Stop Frequency): Specifies the stop frequency.

ID (Identify): Returns the Spectrum Analyser model number to the controller.

IP (Instrument Preset): Performs an instrument preset.

MKCF (Marker to Center Frequency): Sets the center frequency equal to the marker
frequency and moves the marker to the center of the screen.

MKPK (Marker Peak): Positions the active marker on a signal peak.
If an active marker is on the screen, the MKPK parameters move the marker as follows:
HI (highest) moves the active marker to the highest peak.
NH (next highest) moves the active marker to the next signal peak of lower amplitude.
