EXTRIG?
Returns the internal or external trigger setting.
Parameter
None
Response
(Integer) 1 for external trigger, or 0 for internal trigger
FAULT?
Returns the first error code contained in the Product error queue, and then
removes that error code from the queue. You can use the EXPLAIN? query to
get an explanation string for a specified error code. (See the ERR? command,
which returns both the error code and the explanation string.)
A zero value is returned when the error queue is empty, so to read the entire
contents of the error queue, repeat FAULT? until the response is "0".
Parameter
None
Response
(Integer) The error code
FIRSTIN
Sets the input (INPUT 1 OR INPUT 2) chosen at power-up or reset. The setting
is saved in nonvolatile memory.
Parameter
INPUT1 or INPUT2
FIRSTIN?
Returns the setting of FIRSTIN; the input (INPUT 1 OR INPUT 2) chosen at
power-up or reset.
Parameter
None
Response
(CRD) INPUT1 or INPUT2
FORMAT
Use with extreme care. Restores the contents of the non-volatile memory to
factory defaults. The non-volatile memory holds calibration constants and setup
parameters. All calibration data is permanently lost. The Calibration security state
must be set to OFF and the CALIBRATION MODE state must be set to
SERVICE to replace ALL or CAL data, or an execution error occurs.
Parameter
• ALL (Replaces the whole contents with defaults)
• CAL (Replaces all cal constants with defaults)
• SETUP (Replaces setup parameters with defaults)
