ERR?
Syntax:
ERR?
Response:
Returns the error number and a description of the error: e.g., 107,”Frequency above maximum; maximum frequency
is 20.1 GHz” (e.g. following a CW40GZ command).
Description:
This command reports the next entry in the instrument’s error queue. There may be up to 20
messages in the queue; the messages are reported out oldest first. The error report consists
of an error number followed by a description of the error. If the error queue is empty, the error
report is
0, No error
. If the queue fills up, the last (newest) error report is replaced with
350,
Queue overflow
.
*IDN?
Syntax:
*IDN?
Description:
The instrument identification string can be requested with this command. The following string
will be returned: Giga-tronics, model number, serial number, version and build number, such
as Giga-tronics, 12520A, 992604, 1.05-44.5.
*RST
Syntax:
*RST
Description:
This command will cause the instrument to reset. The reset conditions are:
Frequency:
Minimum
Level:
0 dBm
ALC:
