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.

ERFORMANCE

EST

ATA

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.

Option

1 = Stnd

2 = TTL*

NSTALLATION

OTES

(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.
