SYSTem:VERSion?
This command queries 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, 1996.0).
*IDN?
This query command reads 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):
HEWLETT-PACKARD,E3633A or E3634A,0,X.X-X.X-X.X
