P6460 data acquisition probe.
INTRODUCTION
The P6460 is a 100 MHz data acquisition probe suitable for
use with the 1240/
1241 Logic Analyzer 1240D1 and 1240D2
Acquisition Cards and the DAS
91 A24 and 91 AE24 Data
Acquisition Modules. The P6460has nine data channels and
a clock line. When used with the DAS, one
of the data
channels serves as a clock qualifier.
The P6460 probe can also be used with the following DAS
modules:
91 S16/32 Pattern Generation Module
92A16/16E Data Acquisition Module
92S16/32 Pattern Generation Module
These Instructions contain the service information for this
probe.For convenience, put a copy
of them in theback of the
service manual for the logic analyzer that the probe will
usually be used with.
Labels
Two labels are included with yourprobe.Theone with an 8in
theupperleftcorner and a C/Q in the upperrightcorner is for
use with 1240/
1241 Logic Analyzer. The label with a Qin the
upper leftcornerand a
CK in theupperright corn er is foruse
with DAS91A24 and
91 AE24 Data Aquisition Modules.
Operator's Infor mat ion
This manual contains primarily service information. For
operator's information, refer
to the operator's manual of the
instrument that the probe is
to be used with, either the
1240/1241 Logic Analyzer Operator's Manual or the
DAS 9100 Series Operator's Manual.

GROUND CONNECTIONS AND
FREQUENCY
For clock operating fr equencies up to 25 MHz, the 10-inch
lead sets (012-0747-00 or 012-0800-00) with one USER'S
GND lead connected are sufficient.
F
or clock operating frequencies above 25 MHz but below 50
MHz, 10-inch lead sets may be used if both USER'S GND
leads are connected.
For freq uen cies above 50 MHz and noisy environments, be
sure
to use the 5-inch lead sets (012-0987-00) and both
USER'S
GND lea ds with alligator clips.

STATIC PRECAUTIONS
Staticdischargecandamage any semiconductor
in this instrument.
Observe the following precautions to avoid stat ic damage:
1. Minimize handling
of static-sensitive components.
2. Transport and store static-sensitive components or as-
semblies
in their original containers, or on a metal rail, or
on conductive foa
m. Label any package that contains
static-sensitive components
or assemblies.
3. Discharge the static volta
ge from your body by wearing
a wrist strap while handling these components. Servic-
ing static-sensitiveassembliesshould
be performed only
in a static-free
work s tat ion by qualified service
perso
nn e l.

4. Nothing capable of generating or holding a stat ic charge
should be allowed on the work station surface.
5. Keep the component leads sho rt ed together whenever
possible.
6. Pick up co mp onents by the body, never by the leads.
7. Do n ot slide the components over any surface.
8. Avoid handling components
in areas that have a floor or
wo rk-surface covering capable of generating a stat ic
charge.
9. Use a soldering iron that is connected to earth ground.
10 . Use only special anti-static suction type or w ick type
desolder
in g tools.
NOTE
Damage to electrical components may not be
immediatelyapparent. Always followthe precau -
tionary measures listed above when handling
static-sensitive components.

PERFORMANCE CHECK
Specification Checked
The input resistance of each channel should be 1 þÿM©± 1%.
Required Equipment
One digital multimeter with at least 0.2% accuracy at 1 þÿM©.
For example, the Tektronix DM 50 10.
Procedure
1. With the probe disconnected, measure the resistance
between the input
to the channel you are checking and
any other channel. Call this value
Ra.
2. Next, measure the resistance between the input to the
channel you want
to measure and a third channel. Call
this value R
b.
3. Finally, measure the resistance between the two other
channels. Call this value R
e.
4. Calculate the value of the input resistance of the original
channel using:
Ra + Rb - Rc
Rinput = 2
