1-2200 MHz NOISE GENERATOR
NG-283
1 GENERAL
1.1 Description
The NG-283 is a handheld broadband white gaussian noise generator, which is
an ideal tool for testing coaxial networks, components and aligning coaxial cable at all
frequencies between 1 and 2200 MHz.
This instrument is powered by a rechargeable Li-Ion battery or connecting to a
electricity network. The NG-283 allows the user to perform several actions in
combination with a field meter or a spectrum analyser. Among the possible uses are:
frequency response obtained both from active and passive circuits, impedance
matching measurement and stationary wave ratio in association with a reflection bridge,
and detection of abnormalities in transmission lines. These are some functions that the
NG-283 noise generator is a great help for.
