ESCRIPTION

Micronetics NMA-WiFi series products

are specifically designed to perform

interference tests for 802.11a, 802.11b

and ISM products in general. The

Gaussian output can simulate noise

from other ISM devices sharing the

same spectrum as well as thermal

noise. By setting up an exact signal to

interference ratio, one can measure bit

error rate (BER) as well as test how

well the system operates under real

world conditions in general.

The devices consist of a stable noise

source and multistage amplifier for high

output Gaussian noise output. The

units have a built-in voltage regulator

so output is stable even if your supply

voltage is not. They can be ordered

with optional TTL control to switch the

noise off or on from microprocessor

control. Lastly, the units are calibrated

for noise spectral density output cen-

tered at each channel so you know pre-

cisely your interference signal level.

PECIFICATIONS

- Operating Temperature:

-55 to +95 C

Specification definitions:

- Storage Temperature:

Noise Spectral Density, No is the noise power normalized to a 1Hz bandwidth

expressed in units of dBm/Hz

-65 to +125 C

- Supply Voltage:

+15 VDC

- Temperature Stability:

Flatness is specified over the given frequency range. It is the decibel difference

of the high peak to the low peak.

.025 dB/ C

Min Output Level is the threshold where the noise spectral density output must

not fall below anywhere within the frequency range.

- Output Impedance:

50 ohm

- Peak Factor: 5:1

- VSWR: 1.5:1 max.

- Calibration data in dBm/Hz

Max Output Level is the threshold where the noise spectral density output must

not fall below anywhere within the frequency range

_______________________________________

Calibration: The WiFi and WiFi5 modules are calibrated as noise spectral

density output at spot frequencies corresponding to the center frequency of

each 802.11a and 802.11b frequency. For Bluetooth or other ISM devices,

specify the spot frequency points you desire. Data is supplied as a tabular

print-out and is available in space delimitated text file format.
