Chapter 1 Overview
Noise is propagated through diverse routes such
as communication lines and power supply lines.
Many cases of trouble, including false operation
and malfunction caused by noise, are currently on
the rise. To avoid such trouble, it is essential to
identify the noise frequency bands and routes
through which noise enters, and to take appropri-
ate corrective action.
The 3144-20 NOISE SEARCH TESTER can
search for noise frequency bands and routes of
penetration by simply clamping the 9741 CLAMP
ON VOLTAGE SENSOR to the line being mea-
sured.
Moreover, the logging function of the instrument
enables long-time monitoring. The USB interface
allows recorded data to be transferred to a PC,
displayed in graphs, and output to a printer.
