6-3. Summary of Commands and Queries
The following is an alphabetical list of all 5500A Calibrator commands and queries,
including common commands and device-dependent commands. Each command title
includes a graphic that indicates remote interface applicability, IEEE-488 and RS-232,
and command group: Sequential, Overlapped, and Coupled.
IEEE-488 (GPIB) and RS-232 Applicability
IEEE-488 RS-232
xx
Each
command and query has a check box indicating applicability to IEEE-488 (general
purpose interface bus, or GPIB) and RS-232 remote operations. For sorting purposes,
this list ignores the * character that precedes the common commands.
Sequential Commands
Sequential
x
Commands executed immediately as they
are encountered in the data stream are called sequential commands. For more
information, see “Sequential Commands” in Chapter 5.
Overlapped Commands
Overlapped
x
Commands that require additional time
to execute are called overlapped commands because they can overlap the next command
before completing execution. To be sure an overlapped command is not interrupted
during execution, use the *OPC, *OPC?, and *WAI commands to detect command
completion. For more information, see “Overlapped Commands” in Chapter 5.
Coupled Commands
Coupled
x
The commands OUT, WAVE, DC_OFFSET,
CUR_POST, and HARMONIC are coupled commands because they “couple” in a
compound command sequence. Care must be taken to be sure the action of one
command does not disable the action of a second command and thereby cause a fault.
For more information, see “Coupled Commands” in Chapter 5.
BOOST

(Boost command) Activate or deactivate a 5725A Amplifier and set the source
preference to the 5725A Amplifier or to the 5500A Calibrator. An error is reported if the
5725A Amplifier cannot be turned on or off for the present output.
Parameters: ON (activates the connected 5725A Amplifier)
OFF (deactivates the connected 5725A Amplifier)
Example: BOOST ON
Activate the connected 5725A Amplifier if the last OUT command selected an output
supported by the connected 5725A Amplifier.

(Boost query) Return whether or not the 5725A Amplifier is in use for the output and
which output is being boosted.
Responses: VOLTAGE (sourced by the 5725A Amplifier)
CURRENT (sourced by the 5725A Amplifier)
OFF (not sourced by the 5725A Amplifier)
Example: BOOST? returns OFF
Return OFF when the 5725A Amplifier is not in use, or not connected.
