HP 3336B User Manual

Model 3336A/B/C
Up to 15 instruments (including the controller) may be connected in an HP-IB system. The
HP-IB cables have identical stacking connectors on both ends so that several cables can be
connected
to
a
single
source.
As
a
practical
matter,
avoid
stacking
more
than
three
or
four
cables on any one connector. If the stack gets too large, the force on the stack can produce
enough leverage to damage the connector mounting. Be sure that the connector screws are
tightened
firmly
in
place
to
keep
it
from
working
loose
during
use,
and
be
sure
to
observe
the
CAUTION of Figure 2-2.

The 3336A contains metric threaded HP-I8 cable mounting
studs as opposed to English threads. Metric threaded -hp-
10833 A, 8B, C, or D HP-iB cable lockscrews must be used
to secure the cable to the instrument. Identification of the
two types of mounting studs and lockscrews is made by
their color. English threaded fasteners are colored silver and
metric threaded fasteners are colored black. DO NOT mate
silver and black fasteners to each other or the threads of
either or both will be destroyed. Metric threaded HP-/B cable
hardware illustrations and part numbers follow.

System
components
can
be
interconnected
in

However,
to
achieve
reliable
system
performance,
proper
voltage
levels
and
timing
relationships
must
be
maintained.
If
the
system

is
too
long,
the

cannot
be
driven
properly
and
the
