HP 8590 E & L Series Spectrum Analyzers and HP 8591C Cable TV ...

Saving and Recalling Instrument States
The spectrum analyzer’s control settings (or its “state”) can be saved with a computer and
retrieved later to streamline test sequences or repeat manual measurements. Control settings
can be stored in one of eight state registers in the spectrum analyzer, in computer memory, or
on a computer disk.
The first program in this section demonstrates techniques for saving an instrument state, along
with its current trace A data. The second program demonstrates how the state information and
the trace data is read from the computer and returned to the spectrum analyzer.
If you wish to save states in the spectrum analyzer, see the descriptions of the save state
(SAVES) and recall state (RCLS) commands in Chapter 5.

The following two programs read and store a trace from the spectrum analyzer.
