The NMA 2400 Noise Module is
ideal for applications like jamming
and built-in-test where high power
and small size are required. The
internally regulated driver provides
long term highly stable noise out-
put. Optional TTL is available for
microprocessor control.
Each NMA 2400 model is designed
for easy integration into a wide
range of equipment, from test sets
to radar units.

Each unit ships standard with a spectrum analyzer plot
of the noise output.
Upon special request, Micronetics can supply tabular
data in text file format on CD-ROM or floppy disk. The
data points consist of power spectral density at discrete
frequency points across the frequency band.
