Oscilloscope Probe Specifications

FAQ

Can TPI oscilloscope probes be used with Tektronix and Hewlett

Packard scopes?

Yes, TPI oscilloscope probes can be used with most major brands

of scopes.

Why is selecting a probe with the correct bandwidth important?

Choosing a probe with the correct bandwidth enables you to use

your scope to its full potential.

Why do TPI oscilloscope probes have a compensation range

and compensation adjustment?

Since the input of every oscilloscope is different our probes have

a compensation adjustment so the capacitance of the probe can

be adjusted to match the capacitance of the scope input. The

compensation range is the range of adjustment available.

Matching probe and scope capacitance is important to prevent

waveform distortion.

Differential Probe Specifications

What is the benefit of a probe with X1 and X10 switchable

attenuation?

Passive X10 probes allow you to read a signal 10 times the

amplitude of that viewed with a X1 probe. Example: an eight-division

graticule on 5V/Div setting would display a 40 volt peak-to-peak signal

using the X1 setting. You can view a 400 volt signal using the X10

setting.

What is readout?

Readout is an activator pin that protrudes out of the BNC connector of

an X10 or X100 probe that completes a circuit. There are contacts

around the BNC connector on the front of the oscilloscope and the

attenuation is automatically set. If your scope does

not have contacts around the BNC connector, it does not need this

feature.

What probe should I buy?

Select a probe that is at least the same bandwidth as the oscilloscope

you intend to use; however, for optimum performance, select a probe

with two times the bandwidth of your test instrument.

FAQ

What can you measure with a differential probe?

With 20 MHz bandwidth, a switchable attenuation of 20:1,

and 200:1 (part no. ADF25), you can measure high-voltage

circuits, motor speed controls, power supply design, and

high-power electronic converters.

What comes in the probe set?

You will receive one differential probe, 2 probe tips, and 2

retractable sprung probes for accessing small wires for

measurements.

Why is common rejection ratio (CMMR) important for

differential probes?

CMMR is a measure of how well a differential probe will

reject signals common to both test points, leaving the

desired signal to be displayed by the scope

What does the maximum differential voltage specification

tell me?

This specification provides you with the maximum voltage

between the inputs the differential probe can be subjected to.

This is important because the maximum voltage should never

be exceeded.

What is input impedance?

Impedance is a measure of how much a signal will be

restricted. In general, it is best to have high resistance and low

capacitance to ensure signal quality, accuracy of tests, and to

ensure the probe doesn’t load down the circuit under test.
