Appendix C: Interface Specifications
This appendix describes details of the GPIB remote interface of the oscilloĆ
scope. Normally, you will not need this information to use the oscilloscope,
but the information is useful when connecting to controllers of unusual configĆ
uration.
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 mesĆ
sages 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 the controller sends
its talk address 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 controller sends another device's talk
address with ATN asserted. The oscilloscope has talkĆonly capability for
hard copy operation.
H L4 (Listener). The oscilloscope becomes a listener when the controller
sends its listen address with the ATN (Attention) line asserted. The oscilĆ
loscope does not have listenĆonly capability.
H SR1 (Service Request). The oscilloscope asserts the SRQ (Service ReĆ
quest) 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 simultaneousĆ
ly.
H DC1 (Device Clear). The oscilloscope responds to the DCL (Device Clear)
and, when made a listener, the SDC (Selected Device Clear) interface
messages.
H DT1 (Device Trigger). When acting as a listener, the oscilloscope reĆ
sponds to the GET (Group Execute Trigger) interface message.
H C0 (Controller). The oscilloscope cannot control other devices.
H E2 (Electrical). The oscilloscope uses tristate buffers to provide optimal
highĆspeed data transfer.
