OUTPut:RELay {OFF | ON}
Set the state of two TTL signals on the RS-232 connector pin 1 and pin 9. These
signals are intended for use with an external relay and relay driver. At
*RST
,
the
OUTPUT:RELay
state is OFF. See ‘‘
Disconnecting the Output Using an
’’, on page 56 for more information.
N o t e
Do not use the RS-232 interface if you have configured the power supply to output
relay control signals. Internal components on the RS-232 circuitry may be damaged.
OUTPut:RELay?
Query the state of the TTL relay logic signals.
SYSTem:BEEPer
Issue a single beep immediately.
SYSTem:ERRor?
Query the power supply’s error queue. A record of up to 20 errors is stored in
the power supply’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 you have
read all errors from the queue, the
ERROR
annunciator turns off and the errors
are cleared. See ‘‘
’’, starting on page 121 for more details.
SYSTem:VERSion?
Query the power supply to determine the present SCPI version. The returned
value is of a string in the form YYYY.V where the ‘‘Y’s’’ represent the year of
the version, and the ‘‘V’’ represents a version number for that year (for example,
1997.0).
*IDN?
Read the power supply’s identification string. The power supply 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 a revision code which contains three numbers. The first
number is the firmware revision number for the main power supply processor;
the second is for the
input/output
processor; and the third is for the front-panel
processor.
The command returns a string with the following format (be sure to dimension
a string variable with at least
40 characters
):
