the commands are executed programmatically by the controller,
PeakTech
®
1100 performs special
functions requested by the controller.
4.3.4. GPIB Input Command Types
There are 3 types of GPIB input commands; Parameter, Enumerated, and Direct commands. These
are described in the following sections.

PeakTech
®
1100 (e.g., Frequency,
Levels, etc.)
Parameter command format:
