Caution
This instrument contains relays that have a long, but finite
lifespan. When programming the instrument from the IEEE Bus
take care to not constantly exercise them.
To maximize the lifespan of the relays, observe the following good-practice points when
controlling the Instrument from the bus:
1.
Minimize the number of output operate and standby transitions (:OUTP ON | OFF)
that are sent to the instrument.
2. Minimize the number of resets (*RST) sent to the instrument when the output is on.
3. Avoid repeatedly changing between functions (Sine, AM, FM etc) with the output on.
4. Group similar setup points (level and frequency) together rather than send sequences
of disparate setup points.
Introduction
This part of Chapter 4 documents the SCPI (Standard Commands for Programmable
Instruments) Command Set for the Instrument. The commands are presented in a series of
tables that are organiged by functional subsystems, power, AM, FM, Sweep, etc. Also
included are the common commands and the Status Registers. Each table represents a
functional grouping and is preceded by an identifying second order heading. Formal table
headings and introductory paragraphs have been omitted for clarity.
