6-1. Introduction
This section documents remote commands for the 5790A AC Measurement Standard.
Remote commands duplicate almost all activities that can be initiated from the front panel
in local operation.
Table 6-1 summarizes the commands by function. Following the summary table is a
complete alphabetical listing of all commands complete with protocol details. First is a
list of the IEEE-488.2 Common Commands, followed by a list of the 5790A Device-
Dependent Commands.
Separate headings for each command in the listing provide the parameters and responses
(if any), and an example for cases in which the parameters are not self-explanatory.
Response formats, e.g., CRD (Character Response Data), IAD (Indefinite ASCII), and
Binary Block Data, are defined in Table 5-3. Refer to "Using Commands" in Section 5
for meaning of "overlapped," and "long-term" notations in the following command
descriptions. (All commands are sequential unless otherwise noted.)
Table 6-1. Command Summary by Function
IEEE-488.2 Common Commands
*CLS
Clears status. Clears the ESR, the ISCR, and the error queue. Terminates a ending
operation complete command (*OPC).
*ESE Sets event status enable register, described in Status Information section below.
*ESE?
Returns the decimal equivalent of the event status enable register, described in
Status Information section below.
*ESR?
Returns the decimal equivalent of the contents of the event status register (ESR)
and clears it.
*IDN?
Identification query. Gives an <IAD> that identifies the Model number, instrument
serial number, and firmware revision levels
*LRN?
Returns <IAD> which when sent to 5790A restores it to the state in effect when the
*LRN? command was executed.
*OPC
Generate the operation complete message in the Event Status Register when all
pending device operations have been finished
*OPC? Reply with a 1 when all pending operations are complete.
*OPT? Queries which hardware and software options are installed
*PUD
Protected user data command. This command allows the user to store a string of
bytes in a nonvolatile location in the 5790A. This command works only when the
CAL switch on the 5790A back panel is in the ENABLE position (otherwise an
execution error occurs). An execution error also occurs if the argument is over 64
bytes long.
*PUD? Protected user data query
*RCL Restores the 5790A setup from a previous setup saved by *SAV.
*RST
Reset. Resets the state of the instrument to the power-up state, except
autotriggering is stopped.
*SAV Saves the current 5790A setup into setup save area for later use by *RCL.
