The NMA 2500 Dual Bias Noise
Module is a compact high power
noise source ideal for appliations
in jamming, dithering, built-in test
and calibration. The dual bias
voltage allows for greater flexibitli-
ty in system integration and lower
power consumption. The NMA
2500 is packaged in a sealed
housing for ease of integration
into a wide range of military and
commerical applications.

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.

(1) Should be mounted to a thermally conductive baseplate
(2) Select style code T for mechanical clearance of
mating SMA (m) connector nut with respect to
thermally conductive baseplate
(3) Warning: when using a narrow band filter following the
noise module, use a 3 dB or reater pad to prevent
damage caused by refective power.
