Table 6-6. Command Summary (cont.)
Status Commands
IDN? Returns the detailed instrument ID and software version information.
MODE?
Returns the operating mode (MEASUREMENT, CALIBRATION, DIAGNOSTIC,
CALWAITING).
MODESTR? Returns a string that describes what a calibration or diagnostic procedure is doing.
ONTIME? Returns the time in minutes since the power was turned on.
5790B Calibration, Testing, and Diagnostics Commands
ABORT Aborts a measurement, calibration, or diagnostic procedure.
CAL_AC Begins an interactive ac calibration procedure for an ac range.
CAL_AC?
Lists the steps of an interactive calibration procedure or a portion of a procedure as
it would run when requested with a CAL_AC command with the same parameters.
CAL_BACKUP
Makes it so that the next CAL_NEXT command redoes the previously finished
calibration step.
CAL_CLST? Lists the symbolic names for all the calibration constants for a specified range.
CAL_CONST? Returns the value of a particular calibration constant.
CAL_COUNT? Returns the number of times the Calibration state has been unsecured.
CAL_DATE Sets the verification date to the date returned by the internal clock/calendar.
CAL_DATE?
Returns the verification date or the most recent calibration. See the command
description for more information.
CAL_DAYS?
Returns the number of days elapsed since the last verification or calibration. See
the command description for more information.
CAL_DC
Begins a calibration procedure for a dc range. As in CAL_AC, this merely specifies
which step the next CAL_NEXT command does.
CAL_DC?
Lists the steps of an interactive calibration procedure or a portion of a procedure as
it would run when requested with a CAL_DC command that uses the same
parameters.
CAL_FPT
Corrects the reference given for an ac calibration step after the fact, and as a result
changes the resulting calibration constant or constants.
CAL_FPT?
Supplies the first two parameters to be used with a CAL_FPT to correct the next
calibration step to be performed.
CAL_FREQ
Executes the frequency calibration procedure. An error is generated if the
frequency or amplitude measurement is out of range. If an error occurs, the
frequency calibration procedure is not executed.
CAL_I2 Begins the INPUT 2 vs. INPUT 1 calibration procedure.
CAL_I2? Lists the steps in the INPUT 2 vs. INPUT 1 calibration procedure.
CAL_INPUT? Returns the input to which the reference will be applied for the next calibration step.
CAL_INTV
Sets the calibration interval. This is stored in nonvolatile memory and used to
calculate the output uncertainty.
