HP 10400A OPERATING NOTE
INTRODUCTION
The HP 10400A Miniature Passive Probe family
offers modular construction and improved
reliability. Modular construction allows
individual replacement of probe tips, cables,
and chassis assemblies which reduce probe
replacement and repair costs. Improved cable
and strain relief design Increase reliability.
Hewlett-Packard miniature probes significantly
reduce the problem of probing densely
populated IC (integrated circuit) components
or the characteristically minute conductors on
IC boards. These small, lightweight probes
allow measurements that were previously very
difficult, while reducing the hazard of shorting.
The probe body fits in the hand as comfortably
as a pencil. Two accessories that further
simplify and improve connection to dual in-line
packages are the IC grabber (included
accessory) and the IC Test Clip (HP Model
10024A, available accessory).
DESCRIPTION
The HP 10400A Miniature Passive Probe family
consists of fourteen probes and includes: two
1:1 probes for high impedance inputs, eight
10:1 probes, one 100:1 probe for low
capacitance loading and large signals, and
three probes for oscilloscopes with 50 ohm
inputs. HP 10431A and HP 10441A include a
probe sensor on the chassis assembly that
enables HP 54111D and HP 54112D Digitizing
Oscilloscopes to read the probe attenuation
factor.

ACCESSORIES SUPPLIED
The following accessories are supplied with
each probe of the HP 10400A family:
General Purpose Grabber. One general
purpose grabber is supplied with each probe
model. The general purpose grabber is
attached to the probe tip for use on 1C pins
and other typical circuit measurements. HP
Part Number 5061-6160,
Integrated Circuit Grabber. One integrated
circuit (IC) grabber is supplied with each probe
model. The IC grabber is attached to the
probe tip to allow easy and firm grip to an IC
without the hazard of shorting adjacent pins
on the IC. HP Part Number 5061-6161.
Ground Lead. One ground lead with alligator
clip is supplied with each probe model. The
ground lead has a ferrite bead included in its
construction which reduces noise In the
measured signal. HP Part Number 5061-6162.
Barrel Insulator. One barrel insulator is
supplied installed on the tip of each probe
model. The barrel insulator prevents possible
shorting of probe tip and circuitry. Use barrel
Insulator with the general purpose grabber for
correct fit of grabber.
Accessory Package. One accessory package
is supplied with each passive probe. The
accessory package contains: four grounding
spanners, one barrel insulator, eight colored
cable markers, and one adjustment
screwdriver.

ACCESSORIES AVAILABLE
The following accessories may be ordered for
use with the HP 10400A Miniature Passive
Probes:
HP Model 10024A. IC clip provides easy
probing and good high-frequency grounding of
dual in-line packages and includes four
insulated circuit interface pins. Additional
circuit interface pins are available in packages
of twelve pins. Each pin has a tip on the end
so that probes such as those on HP logic
analyzers may be connected for fast,
functional checks of circuit operation. The HP
10024A is shown in figure 1.
HP Model 10211 A. IC clip, same as HP
10024A except for 24-pin integrated circuits.

HP Models 1250-2427 and 1250-2428. PC
(printed circuit) Board Miniature Sockets, ideal
for breadboard circuit applications where it is
desirable to make a reliable circuit connection
between the miniature probe tip and a test
circuit. (Soldering the probe tip in place is not
recommended.) The sockets are also useful in
production PC board applications as an
oscilloscope test point. The HP 1250-2427
plugs into the socket parallel to the circuit.
