System Information Commands

These commands are used to obtain system-level information.
*IDN?
This IEEE488.2 Common Command queries the instrument for the
identification string. The returned string will contain the manufacturer
identification, the model number, the serial number, and the firmware
revision.
SYSTem:ERRor?
This query returns a variant of the instrument's error queue. Errors are
retrieved in first-in-first-out (FIFO) order. The first error returned is the
first error stored. See the " Error Messages" chapter on page 165 for the
error numbers and messages.
Depending upon your programming environment, this query may return
an integer containing the error number, or a variant containing the error
number and error message.
When all the errors from the queue are read, the errors are cleared and
the ERROR annunciator turns off. When the queue is empty, each
following SYSTem:ERRor? query returns: +0, "No error". To clear all
error numbers/messages in the queue, execute the *CLS command or
power-on the instrument.
The queue holds a maximum of 10 error number/message pairs. If the
queue overflows, the last error number/message in the queue is replaced
by: -350, "Queue overflow". The least recent error numbers/messages
remain in the queue, and the most recent are discarded.
SYSTem:VERSion?
This query returns a string indicating the SCPI version implemented on
the mainframe control board. The string is in the form: "Version A.02.00"
SYSTem:CTYPE? <slot>
This query returns a string containing the module identification in the
specified slot. The slot parameter is a decimal ranging from 0 to 9
(mainframe dependent). Valid slot numbers are:
3499A slots 0 through 5
3499B slots 0 through 2
3499C slots 0 through 9
