Probes
Teledyne LeCroy offers a variety probes for use with your oscillocope.
The types compatible with the LabMaster 10 Zi are listed below. Visit
teledynelecroy.com for specifications and ordering information.

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. These probes are typically low-bandwidth and
require an adapter to connect to the 2.92 mm and 1.85 mm
interfaces on the 10-xxZi Acquisition Modules.

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. Some models of differential probes may
require an adapter to connect to the 2.92 mm and 1.85 mm
interfaces on the 10-xxZi Acquisition Modules.
Connecting to 1.85 mm Probe Interfaces
Teledyne LeCroy's LabMaster 10 Zi oscilloscopes utilize a 1.85mm probe
interface for inputs up to 65 GHz. This interface consists of a precision
male connector with a female-female barrel adapter and a LEMO power
and communication connector. It offers 50 Ω input impedance only.
For additional connection interface information, refer to Dual Channel
Acquisition in the online help.
The male connector is mounted onto the oscilloscope connector panel
when delivered.
The female-female barrel adapter inserts into the male connector.
Grasp the outer ring of the female connector, insert the barrel adapter,
and hand tighten. Then, use a torque wrench to ensure the proper
insertion force for the best connection.
