Introduction
To get the most out of your
oscilloscope, you need the right
probes and accessories for your
particular applications. Whether
you need the high bandwidth and
low loading of an active probe, an
easy way to connect to surface
mount ICs or a passive probe to
measure high voltages, there are
a wide selection of high-quality
probes and accessories for your

How To Select A Probe
Selecting the correct probe for your
oscilloscope measurement should not
be difficult. This brochure provides
suggestions on how to make the best
decision. Following is a list of probe
parameters you need to consider when you
select a probe for a given measurement.
Maximum input voltage (Vmax)
Probe tip form factor
To ensure user safety, help protect the
oscilloscope input from destructive
voltage, and avoid damage to the probe,
select a probe that is rated for a higher
voltage than the signal you intend to test.
Attenuation
Probe compensation range
Your probe must make a reliable
connection to the test point, and you may
want it to grab the test point. Generally,
this requires a small and light probe and a
tip or grabber that is compatible with the
test point. SMT and fine-pitch geometries
make this issue especially critical.
Choose the attenuation ratio of the probe
(1:1, 10:1, 100:1, 1000:1) to match the test
signal amplitude to the oscilloscope’s
vertical sensitivity range. Higher attenuation
probe allows the measurement range of a
scope to be extended, and lower attenuation
probe allows for lower noise measurement.
Most passive probes have a specification
that lists the oscilloscope input
capacitance range over which they can
be used. When choosing a passive probe,
be sure that the oscilloscope’s input
capacitance lies within the probe’s
compensation range or you will not be
able to adjust the probe to achieve a
correctly compensated square wave signal.
Bandwidth (BW)
The probe’s rated bandwidth should
match the oscilloscope’s and be adequate
for the test signal. However, at higher
frequencies, grounded lead inductance and
input capacitance often influence system
performance more than probe bandwidth.
Input resistance (Rin)
Input impedance is used to describe the
loading effects of a probe. At DC and low
frequency ranges, the probe’s resistive
component is the main factor that loads
down the circuit under test. However, as the
frequency goes up, the capacitance of the
probe tip, in parallel with the DC resistance,
starts to reduce the input impedance of the
probe, resulting in greater loading and a
more adverse effect to the target.
Input capacitance (Cin)
Excessive input capacitance (sometimes
called tip capacitance) slows down the
system’s pulse response. Usually the least
input capacitance possible is best.
Probe output termination
Most oscilloscopes have 1-MΩ and/or
50 Ω input resistance. For proper signal
transfer and optimum signal integrity, it’s
important that the probe’s R and C match
the R and C of the oscilloscope it is to be
used with. For example, 50 Ω terminated
probes should be used with 50 Ω scope
inputs. Similarly, 1 MΩ terminated probes
should be used on scopes with a 1 MΩ
input resistance.
Probe interface
Most Keysight oscilloscope probes offer
either a BNC type of probe interface or
the AutoProbe interface. The AutoProbe
interface is an intelligent communication
and power link between compatible
probes and the Infiniium or InfiniiVision
Series oscilloscopes. The AutoProbe
identifies the type of probe attached
and sets up the proper input impedance,
attenuation ratio, probe power, and offset
range as needed.
Single-ended, Differential or
InfiniiMode Probe
Two most common voltage probe types
are single-ended and differential probe.
Differential probes measure the voltage
difference between any two input points
in contrast to a single-ended probe,
which measures input voltage relative to
ground. Differential probes are especially
popular for measuring high-frequency
signals or signals where neither are
referenced to ground. Differential probes
use a differential amplifier to convert
the difference between two signals into
a voltage that can be sent to a typical
single-ended scope input.
A differential probe can be used to make
single-ended measurements by using its
negative input as a
ground reference contact and there
are several advantages to using a
differential probe to make single-ended
measurement. New InfiniiMode probes
offer multiple modes that can measure
single-ended, differential, and commonmode characteristics of a differential
signal with a signal connection.

Types of Probes
Passive probes
The most widely used type of oscilloscope probe is the “passive
probe.” Passive probes are also the most rugged and economical.
There are no active components such as transistors or amplifiers in
the probe, and therefore passive probes do not need to be powered.

Types of Probes (Continued)
Single-ended active probes
Active probes contain a small, active amplifier built into the probe body near the probe
tip. This arrangement makes it possible to keep the probe input capacitance very low,
usually less than 2 pF. This low capacitance results in high input impedance on high
frequencies. It has the best overall combination of resistive and capacitive loading. With
such low loading, active probes can be used on high-impedance circuits that would
be seriously loaded by passive probes. Active probes are the least intrusive of all the
probes.

Differential active probes
A “differential” probe is an active probe that has two inputs, one positive and one
negative, as well as a separate ground lead. It drives a single-terminated 50-Ω cable to
transmit its output to one oscilloscope channel. The output signal is proportional to the
difference between the voltages appearing at the two inputs. A differential probe is used
to look at signals that are referenced to each other instead of earth ground and to look at
small signals in the presence of large DC offsets or other common mode signals such as
power line noise.

Current probes
Current probes sense the current flowing through a conductor and convert it to a voltage that can
be viewed and measured on an oscilloscope. Keysight current probes use a hybrid technology
that includes a Hall-effect sensor, which senses the DC current, and a current transformer, which
senses the AC current. Using split core construction, the current probe easily clips on and off of
a conductor, making it unnecessary to make an electrical connection to the circuit. Measurement
bandwidths from DC to 150 MHz are available. The new N7040A/41A/42A is a family of Rogowski
AC current probe for measuring large AC current conveniently. These probes have a flexible
clip-around sensor coil that can easily be wrapped around current carrying test points for
measurement and can measure large current without increase in transducer size.
