Registers

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.

*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.

SYST:VERS?

will return the SCPI version to which the unit complies (for example 1997-0).

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.
