14. SCPI Command Reference
14.1 Introduction
Related Commands
Where appropriate, related commands or queries are included. These are listed because they
are either directly related by function, or because reading about them will clarify or enhance
your understanding of the original command or query.
This chapter is organized as follows:
•
Subsystem commands, arranged by subsystem
· IEEE 488.2 common commands
These commands still available to the user for the RS232C interface.
14.2 Subsystem Commands
Subsystem commands are specific to AC source functions. They can be a single command or
a group of commands. The groups are comprised of commands that extend one or more levels
below the root. The description of common commands follows the description of the
subsystem commands.
The subsystem command groups are listed in alphabetical order and the commands within
each subsystem are grouped alphabetically under the subsystem. Commands followed by a
question mark (?) take only the query form. When commands take both the command and
query form, this is noted in the syntax descriptions.
14.2.1 Measurement Subsystem
This subsystem programs the current and voltage measurement capability of the P Series AC
source.
Subsystem Syntax
:MEASure
:CURRent?
Returns the rms value of current
:VOLTage?
Returns the rms value of voltage
MEASure:CURRent?
This query returns the rms value of the output AC current being sourced at the output
terminals. Note that the output relay must be closed to obtain current flow.
