SCPI Commands for Digital Interfaces
142 Operating Manual for XDC Series Power Supply
Identification
Query
The identification query command returns a string that states the manufacturer,
model, serial number, and firmware revision.
*IDN?
may return “Xantrex, XDC 60-100, 100000, 3.000/0/0/0000.
Option
Identification
Query
*OPT?
or
SYST[<channel>]:OPTion?
The option identification query returns a string listing any reportable options that are
installed in the power supply. Reportable options are GPIB and CANbus, but may
include others in the future. A zero will be returned if no options are installed.
Example:
*OPT? may return "GPIB, CANBUS" to indicate that both the GPIB and CANbus
(Multichannel/Current Share) options are installed.
SCPI Version
Query
SYST:VERS?
will return the SCPI version to which the unit complies (for example 1997-0).
Status
Registers
The Status Register structure is mandatory for SCPI and IEEE 488.2 compliance.
The register bits are defined by the SCPI and IEEE 488.2 standards.
Each status register has a Condition, Event, and Enable register and transition filters.
See “Status Register Commands” on page 157 for commands to read or change their
values.
Condition Register
Transitions of the condition register are automatic and reflect the condition of the
instrument at the moment. Reading a condition register has no effect on the contents.
Event Register
The event register bits are set automatically to correspond with changes in the
condition register. The rules are dependent on the positive and negative transition
registers. Reading an event register clears it. The *CLS command clears all event
registers.
