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.

Specification definitions:
Noise Spectral Density,
No is the noise power normalized to a 1Hz bandwidth
expressed in units of dBm/Hz
Flatness
is specified over the given frequency range. It is the decibel difference
of the high peak to the low peak.
Min Output Level
is the threshold where the noise spectral density output must
not fall below anywhere within the frequency range.
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.
