Appendix C: Interface Specifications
This appendix describes details of the GPIB remote interface of the oscilloscope.
Normally, you will not need this information to use the oscilloscope, but the
information is useful when connecting to controllers of unusual configuration.
GPIB Function Subsets
The oscilloscope supports many GPIB function subsets, as listed below. Some of
the listings describe subsets that the oscilloscope does not support.
H SH1 (Source Handshake). The oscilloscope can transmit multiline messages
across the GPIB.
H AH1 (Acceptor Handshake). The oscilloscope can receive multiline
messages across the GPIB.
H T5 (Talker). The oscilloscope becomes a talker when its talk address is sent
with the ATN (Attention) line asserted. It can send both response data and
status information when responding to a serial poll. It ceases to be a talker
when the talk address if another device is sent with ATN asserted. The
oscilloscope has talk-only capability for hardcopy operation.
H L4 (Listener). The oscilloscope becomes a listener when its listen address is
sent with the ATN (Attention) line asserted. The oscilloscope does not have
listen-only capability.
H SR1 (Service Request). The oscilloscope asserts an SRQ (Service Request)
line to notify the controller when it requires service.
H RL1 (Remote/Local). The oscilloscope responds to both the GTL (Go To
Local) and LLO (Local Lock Out) interface messages.
H PP0 (Parallel Poll). The oscilloscope has no parallel poll capability. It does
not respond to the following interface messages: PPC, PPD, PPE, and PPU.
The oscilloscope does not send out a status message when the ATN
(Attention) and EOI (End or Identify) lines are asserted simultaneously.
H DC1 (Device Clear). The oscilloscope responds to the DCL (Device Clear)
and, when made a listener, the SDC (Selected Device Clear) interface
messages.
