Hewlett-Packard
instruments use a
two-section,
eight-cligit
serial
number,
that
is,
000-00000.
The first
three
digits
are
an
identification
number;
the
last five
digits
are
the instrument
serial
number.
If
the
identification
number on the
instru-
ment daes not
agree
with
the
identification

The
-hp-
Model 6960A
DC
power supply produces a
regulated
DC
voltage
conti-
nuously
adjustable
from 0 to 36 V up to a
current
of
300 rnA, or from 0 to
18
V up
to a
current
of
600
rnA,
according
to
which
range
has
been
selected
by means
of
the
front
panel
push
buttons.
The supply makes load

performance
idepencient
of
external

influences,
has
very
low source
impedance
and
excellent
regulation
against
change
in
line
and
load.
This supply
is
especially
useful as a source
of
power for transistor
circuits
because
it
features
a
