System-Related
Commands
Using The Instrument 3-42
System-related commands are used to place the instrument in a known state,
clear the instrument to its defaults, or query the generator for system errors or
identification. The following is an overview of the system-related commands.
The query:
SYSTem:ERRor?
reads one error from the error queue. Up to 30 errors can be stored in the
generator's error queue. Errors are retrieved in first-in-first-out (FIFO) order. The
first error returned is the first error that was stored. When all errors have been
read from the queue, the generator returns +0, "No error".
If more than 30 errors have occurred, the last error stored in the queue (the
most current error) is replaced with -350,"Too many errors". No additional
errors are stored until all errors have been removed from the queue. The error
queue is cleared only when power is cycled off or after the execution of a *CLS
command. The *RST command does not clear the error queue.
The query:
SYST:ERRor?
queries the system error queue and returns a string with the following format:
-102,"Syntax error". A complete list of errors that can be detected by the
generator is given in Chapter 4.
The query:
SYSTem:VERSion?
queries the generator to determine the present SCPI revision and returns a
string similar to "1993.0"
The query:
*IDN?
reads the generator's identification string. The generator returns four fields
separated by commas. The first field is the manufacturer's name, the second
field is the model number, the third field is not used (always "0") and the fourth
field is the firmware revision number. The command returns "Racal
Instruments,3162B,0,1.0".
The commands:
RESet
*RST
reset the generator to its default state. The *RST and RES commands have no
effect on status registers, VXIbus states, or SCPI command set.
