E3632A User’s Guide 49
The following statement shows how to display a message on
the front panel from an Agilent controller.
DISP:TEXT ‘HELLO’
Firmware revision query
The power supply has three microprocessors for control of
various internal systems. You can query the power supply to
determine which revision of firmware is installed for each
microprocessor.
You can query the firmware revision from the remote
interface only.
The power supply returns four fields separated by commas
and the fourth field is a revision code which contains three
numbers. The first number is the firmware revision number
for the main processor, the second is for the input/output
processor, and the third is for the front- panel processor.
Remote interface operation
*IDN?
The above command returns a string in the form:
HEWLETT-PACKARD,E3632A,0,X.X-X.X-X.X
Be sure to dimension a string variable with at least
40 characters.
SCPI language version
The power supply complies with the rules and regulations of
the present version of Standard Commands for
Programmable Instruments (SCPI). You can determine the
SCPI version with which the power supply is in compliance
by sending a command from the remote interface.
