Operating the Probe
Introduction
Introduction
The 1141A probe with the 1142A Probe Control and Power Module
allows measurement of small differential signals in the presence of
much larger common- mode signals. It has the following major
features:
■
200 MHz bandwidth
■
Variable offset
■
dc reject
■
ac coupling
■
Remote operating capability
The variable offset capability can be used to measure small ac
signals in the presence of much larger dc levels. Remote operation
of key features allows the use of the probe system in automatic test
situations.
The probe can be used with an oscilloscope, spectrum analyzer, or
any instrument where differential probing is required and a
compatible 50
Ω
input is available.
