Release 3.0 223
Appendix D. GPIB
Overview
This power supply can be programmed from a remote terminal using a General
Purpose Interface Bus (GPIB) interface. Communications over the GPIB interface
meet IEEE 488.2 standards and are SCPI compliant.

Codes and Standards

The GPIB interface of the this Programmable DC Power Supply has been
implemented according to IEEE standard 488.1-1987, “IEEE Standard Digital
Interface for Programmable Instrumentation.”
The communications protocol complies with IEEE 488.2-1992.

Message Terminators

The GPIB End of message (EOM) terminators can be the END message (EOI), the
ASCII code for line feed (LF) or both.
The power supply terminates responses with line feed (LF).

Address Range

Primary
Address
The power supply will respond to any GPIB address in the range 1 to 30.
Secondary
Address
The power supply does not support secondary addressing.

Service Request and Polling

The power supply's serial poll responses and SRQ generation use an IEEE 488.2
reporting structure. See“Status Registers” on page 142.
The Request Service bit (bit 6) in the Status Byte will generate a service request
(SRQ) on the GPIB.
The power supply can be set up to generate a service request (SRQ) at power-on. Use
the command:
SYSTem:COMMunicate:GPIB:PONSrq [ON|OFF|1|0]
