NMA 2500 SERIES DUAL BIAS NOISE MODULES 10 MHZ TO 8.5 GHZ 5V and 12V Bias DESCRIPTION REV 6.2008 NMA 2500 MODULES MODEL NMA2510 NMA2511 NMA2512 NMA2513 NMA2514 NMA2515 NMA2516 NMA2517 FREQUENCY 10MHz - 1.0GHz 10MHz - 1.5GHz 10MHz - 2.0GHz 10MHz - 4.0GHz 100MHz - 6.0GHz 30MHz - 3.0GHz 7.8GHz - 8.5GHz 2.0GHz - 8.0GHz 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 flexibitlity 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.

PERFORMANCE TEST DATA 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 CDROM or floppy disk. The data points consist of power spectral density at discrete frequency points across the frequency band. APPLICATIONS ■ Frequency response built-in-test (BIT) for communication receivers ■ Antenna/RF front end testing ■ 70/140 MHz & L-Band modem BER testing ■ Noise and interference simulation ■ Jamming / jamming simulation ■ Power distribution calibration of multiple receiver systems USEFUL NOISE CONVERSIONS 0 dB ENR = -174 dBm/Hz Power (dBm) = N0 +10log (BW) where: N0 = Noise spectral density in dBm/Hz BW = Bandwidth in Hz (equ 1) (equ 2) HOW TO ORDER NMA-25XX-XX Option 1 = Stnd 2 = TTL* INSTALLATION NOTES (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.
