System-Related
Commands
System-related commands are used to place the instrument in a
known state, clear the instrument to its defaults, or to query the
generator for its errors or identity. The following is an overview
of the system-related commands.
The query:
SYSTem:ERRor?
reads one error from the error queue. A record of 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 r0, "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:ERR
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 version number. The command returns "Racal
Instruments,3152A,0,1.0". (Assuming the firmware revision is
"
0
")
