>> Attenuation: Ratio of the output signal to the input signal. Attenuation should remain constant
decreasing by 3dB only as the frequency increases to the maximum bandwidth.
>> Bandwidth: The maximum -3dB frequency that can be expected.

>> Cable Length: Length of the cable from the end of the probe to the end of the connector. It is
important to use a probe with just enough cable length for your needs. Long cables increase the
capacitance and propagation delay of the probe.
>> Compensation Range: The range a probe can be compensated to match the input capacitance of
the test equipment it is being used with.
>> IEC 1010: Probes with the IEC 1010 category rating have been designed for safety.
>> Input Impedance: The total resistance and capacitance as measured at the tip of the probe. This
specification is used to define the loading effect of a probe. At frequencies under 1MHz the input
resistance of the probe will have the most influence. At higher frequencies the input capacitance will
have the most influence.

Oscilloscope / Differential Probe Selection
Selecting the correct oscilloscope probe ensures accuracy and can
improve the performance of your test instrument. TPI offers a
wide range of high quality oscilloscope probes designed to
meet the most demanding applications.
The IP series monolithic probes have switchable
attenuation and are available in 60 and 250MHz. These
probes are ideal for technicians that need a basic oscilloscope
probe.
The slimline design P and SP series probes are available in fixed or switchable attenuation.
These series of probes are perfect for the technician needing additional features such as
replaceable cable and interchangeable probe tip. The compensation adjustment for these probes
is located in the BNC to eliminate noise pickup.

TPI also offers three models of high voltage differential probes all with high common mode
rejection, wide bandwidth, and fast rise times. Differential probes enable the viewing of signals
not referenced to earth ground and provide better performance than a matched pair of single
ended oscilloscope probes when measuring these types of signals.
Several important factors must be taken into account when selecting the proper probe.
• The probe should have sufficient bandwidth and rise time for the test instrument and
application. Choose a probe with at least an equal bandwidth as the scope it will be used with.
For best performance a probe with twice the bandwidth as the scope should be selected.
• For oscilloscope probes, the input capacitance of your oscilloscope should
be within the compensation range specification of the probe. In
addition, if your oscilloscope has readout function, select a
probe with this capability.

Refer to pages 2-3
for specifications.
• For differential probes, make sure the maximum
differential voltage is adequate for your application
and the common mode rejection specification meets
the requirements of the tests being performed.
Refer to the oscilloscope and differential probe specification tables
to select the correct probe for your application.
