GPS7500 Noise & Interference Generator

The Noise Com GPS7500 Noise & Interference Generator is ca-

pable of generating up to 40 MHz bandwidth of arbitrary wave-

forms for the test of susceptibility of GPS receivers to jamming,

pulsed, CW, noise and any interference which we could imagine.

A modular approach provides for expandability with additional

independently programmable generators for L1, L2 or L5 bands.

This unique combination allows for a single instrument to sup-

port today’s as well as possible future GPS standards.

Benefits

Integrated Approach: Contains one or optionally two indepen-

dent arbitrary waveform generators. This allows for simultane-

ous testing of the L1 and L2 or L5 frequencies.

Value: Built-in GPS signal and interference combiner, Gaussian

noise source and power meter for automatic high and low power

level calibrations.

Protected Investment: As additional independent bands are

needed the GPS7500 can be easily upgraded. Arbitrary wave-

form generator allows creation of any interference or jamming

waveform which we could image.

True “Standard” for GPS: The GPS7500 was designed to support

all of the current GPS tests of susceptibility to noise and interfer-

ence of DO-229, DO-235 and DO-253.

Ease of Use: Access table of pre-stored GPS testing parameters

made by pressing one button. Cursors automatically lead to GPS

standard template, giving the operator a quick view of all neces-

sary test criteria.
