P6106A Instruction Manual 1

P6106A Passive Probe

Thank you for choosing a Tektronix passive probe. This manual provides the

information necessary to begin making measurements with your P6106A probe.

Topics are presented in the following order:

HDescription—A description of the probe and its options.

HSafety—A review of important safety considerations.

HInstallation—Information about attaching the probe to an instrument, and

attaching accessories to the probe.

HOperating Considerations—Information about using the probe.

HMaintenance—Instructions for cleaning the probe and replacing major

assemblies.

HReplaceable Parts—An exploded view of the probe and a list of replaceable

parts.

Description

The P6106A is a miniature, 10X-attenuating passive probe that is compatible

with general purpose oscilloscopes having a 1 MW input impedance.

The P6106A is compatible with Tektronix oscilloscopes that automatically detect

and display the attenuation factor of the attached probe.

The P6106A has a ground-reference push button that momentarily grounds the

probe output. This feature allows you to quickly identify the oscilloscope display

associated with one of several attached probes as well as making ground-refer-

enced measurements easier.

The P6106A is available with the following cable lengths:

Standard 2 meters

Option 01 1 meter

Each probe option is fully compatible with Tektronix accessories for miniature

probes.

2P6106A Instruction Manual

Installation

This section describes both attaching the probe to an oscilloscope and using the

standard accessories with the probe.

The probe uses a BNC connector to attach to an oscilloscope input connector. To

ensure optimum performance from your probe/oscilloscope measurement

system, verify that the probe and oscilloscope are appropriately matched. The

oscilloscope input impedance should be 1 MW. The oscilloscope input capaci-

tance should be between 15 and 35 pF. Refer to “Compensation Range” in

Table 1 on page 8 for more information.

Your P6106A is shipped with the following accessories:

HThis instruction manual—Read these instructions to familiarize yourself

with he features, specifications, and operation of the P6106A passive probe.

HAccessory pouch—(not shown) Use the accessory pouch to store the probe

and its accessories when they are not being used.

HAdjustment tool—Use the insulated adjustment tool to adjust the low

frequency trimmer in the probe compensation box.

HIC protector tip—Use the IC protector tip to keep the metal sleeve of the

probe tip from accidentally shorting together the leads of an IC or other

circuit element. The shape of the protector tip helps you place the tip

accurately onto an IC lead.

HRetractable hook tip—Use the retractable hook tip to make hands-free

measurements. The hook tip attaches to components having leads, such as

resistors, capacitors, and discrete semiconductors. You can also grip stripped

wire, jumpers, busses, and test pins with the retractable hook.

For maximum flexibility with the hook tip, use the twelve-inch ground lead.

For precise measurements at high frequency, however, long ground leads

may have too much inductance. In these cases you should use the five-inch

ground lead.

To remove the hook tip, simply pull it off the probe. Reinstall it by pushing

it firmly onto the probe tip.

HGround cover—Use the protective ground cover to keep the metal sleeve of

the probe tip from accidentally shorting circuit elements to ground. Remove

the ground cover before installing the retractable hook tip.

HMarker rings—Use the marker rings to help you keep track of individual

probes and signal sources when you have a complicated test setup. Use the

marker rings whenever you want to identify a particular probe for any

reason.To make probe identification easy, clip matching colored rings onto

the probe cable and tip as shown.

HThree-inch ground lead—Use the Three-inch ground lead to establish a

ground reference for your measurements. Whenever freedom from aberra-

tions and amplitude accuracy are more important than probe reach and

flexibility, use the shortest ground lead possible.

To attach the ground lead to the probe, insert the spring clip into the

receptacle as shown. If the alligator clip is not attached, screw it onto the

threaded end of the lead.

HFive-inch ground lead—Use the long ground lead when a long reach is

important and high-frequency information is not. Because of the high

inductance associated with long ground leads, you should not use them for

precise measurements above approximately 30 MHz (or for pulses with rise

times less than about 11 ns). Long ground leads are ideal for quick trouble-

shooting when you are looking for the presence or absence of a signal and

are not concerned with the precision of the measurement.

The five-inch ground lead attaches in the same manner as the three-inch lead.

HAlligator clip—Use the alligator clip with one of the ground leads. Screw

the alligator clip onto the threaded end of a ground lead.

Operating Considerations

This information in this section will help you make the most effective use of

your P6106A probe.

HReadout pin—The BNC connector of the probe includes a spring-loaded pin

that connects to a mating contact ring on certain oscilloscopes. These

oscilloscopes recognize the attenuation factor of the probe and automatically

correct the oscilloscope indication of scale factor. You can determine if your

oscilloscope supports this feature by watching the oscilloscope vertical scale

factor readout when attaching the probe. If the displayed scale changes by a

factor of 10—for instance, from 10 mV to 100 mV—your oscilloscope

supports this feature.

HGround-reference push button—Press the ground-reference push button to

momentarily short the signal output of the probe to ground (the signal under

test is not affected). Using the ground-reference push button allows you to

quickly note or verify the ground reference of a DC measurement. If your

oscilloscope is displaying several traces, pressing the ground-reference push

button also helps you to identify which trace is associated with the probe.

WARNING. To avoid electric shock when using the probe, keep fingers behind the

guard on the probe body.

In order for an amplitude measurement to be meaningful, you must give the

measurement some point of reference. The ground lead provides access to this

ground reference.

When you subsequently touch your probe tip to a circuit element, you introduce

additional resistance, capacitance, and inductance into the circuit (Figure 1).
