LabMaster 10 Zi Oscilloscopes

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
female connector with a male-male 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 1.85 mm high-bandwidth electrical paths are comprised of two
items – the precision female connector and a male-male barrel adapter.
The female connector is mounted into the oscilloscope connector panel.
It is a low-loss connector that is designed for frequent
connect/disconnects.
