HP 1630D

Connecting the HP 1630
and
HP 1631 logic analyzers to
minicomputers is
facilitated through
minicomputer interfaces for
three of the
most popular
minicomputer buses :
HP 10275A PDP-11
UNIBUS
U
Interface
HP 10276A
LSI Q-BUS
C
Interface**
HP 52126A
MULTIBUS
Interface ***
The interface boards plug
into the
respective buses . A ribbon
cable
extending from the
board can either be
connected to
the logic analyzer, or for
convenience
through the HP 10320A
user-definable
interface module with
an
HP
10269B probe interface .
Switches
on each interface board
qualify
information routed to the
logic
analyzer
or preprocessor by the
selected
activity
type . Any combination of
monitored
activities may be selected
for
a logic
analysis measurement
.
