OUTPut:RELay {OFF|ON}
Sets the state of two TTL signals on the RS-232 connector. These signals are
intended for use with an external relay and relay driver. At
*RST, the
OUTPut:RELay state is OFF. Refer to “Disconnecting the output using an
external relay” on page 73 for more information.
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 are stored in
the power supply’s error queue. Errors are retrieved in the 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. Refer to Chapter 4, "Error Messages" 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 represent the year of the
version, and the V represents a version number for that year (for example,
1997.0).
SYSTem:COMMunicate:GPIB:RDEVice:ADDRess {<numeric value>}
SYSTem:COMMunicate:GPIB:RDEVice:ADDRess?
Set or query the bus address of the peripheral device. Changing the address
with this command does not affect the address of the peripheral device. It does
affect the address to which data is sent by the instrument.
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.
