5820A
Operators Manual
FAULT?
(IEEE-488, RS-232)
This is provided for 5700A compatibility. ERR? is preferred.
(Fault query) Returns the first error code contained in the 5820A Calibrator error queue,
then remove that error from the queue. After obtaining the error code, use the EXPLAIN?
command to view an explanation. A zero value is returned when the error queue is
empty. To read the entire contents of the error queue, repeat FAULT? until the response
is 0. (Only system errors appear in the error queue.)
Response:
Example:
Return the first error code in the error queue, number 539. To view an explanation of the
error, enter the command EXPLAIN? 539.
FORMAT
(IEEE-488, RS-232)
(Format command) Use with extreme care. Restores the contents of the nonvolatile
memory device to factory defaults. The memory holds calibration constants and setup
parameters. You lose all calibration data permanently. The CALIBRATION switch on
the rear panel of the 5820A Calibrator must be set in the ENABLE position or an
execution error occurs, except for FORMAT SETUP.
Parameter:
Example:
Replace the setup parameters with the default setup values (below). (The FORMAT ALL
command is the same as FORMAT CAL and then FORMAT SETUP.) The FORMAT
SETUP command also clears the *PUD string (see the *PUD command) and SRQSTR is
set to "SRQ: %02x %02x %04x %04x" (see the SRQSTR command) and SPLSTR is set
to "SPL: %02x %02x %04x %04x" (see the SPLSTR command).
