SYSTem:VERSion?
Query the power supply to determine the present SCPI
version. The returned value is a string in the form of
YYYY.V where the Y represents the year of the version and
the V represents the 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.
*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
(make sure to dimension a string variable with at least 40
characters):
Agilent Technologies,E3640A,0,X.X-Y.Y-Z.Z
(E3640A model)
*TST?
Perform a complete self- test of the power supply and return
0 if the self- test passes or 1 or any non- zero value if it fails.
If the self- test fails, an error message is also generated with
additional information on why the test has failed.
