to connect a 25 GHz probing system using 2.92 mm and LEMO connections
for connection to a ProLink input.
Connecting the ProLink Probe Adapter is done in a similar way as
connecting a ProLink Interface Adapter.
Probes
Teledyne LeCroy offers a variety of passive and active probes for use with
your X-Stream oscilloscope. Vi

ordering information.
Current Probes - Current Probes measure the current passing
through a wire; current probes do not use the traditional probing
style of placing a tip onto a test point. Instead, a wire is placed inside
the jaw of the probe, which allows the probe to measure the current
(in Amps).
Active Probes - There are two different types of active probes:
single-ended and differential.
Single-Ended - A single-ended active probe is associated with
measuring voltages at high frequencies. Measurement with an active
probe requires a test point and a ground point. The ground (also
called earth) acts as a zero reference for the test point
measurement.
Differential Probes - Differential active probes are like two probes in
one. Instead of measuring a test point in relation to a ground point
(like single-ended active probes), differential probes measure the
difference in voltage of a test point in relation to another test point.
Passive Probes - Passive probes measure voltages at lower
frequencies (<500 MHz). They have higher input capacitance (input
C) and do not need power to operate (unlike active probes). At
higher frequencies, higher input capacitance loads the test circuit,
