General

What is AWGN?

Additive white Gaussian noise has a Gaussian PDF (histogram) in the time domain, and a flat PSD (power spectral density) in the frequency domain. Noisecom specializes in high crest factor, (>18 dB, or > 7σ) noise sources for use in Jitter applications, and high power flat spectrums for signal interference, or satellite communication link testing.

What is ENR?

ENR (excess noise ratio) is the ratio of a hot source Th to a cold source Tc, displayed on a logarithmic scale. The purpose of this scale is to compare two temperatures and convert this difference into power values that conventional electrical instruments cannot measure. These values can be used to calculate parameters like noise figure. A popular scale comparing thermal noise power at -174 dBm/Hz  (1mW@ 50Ω) to the average outside air temperature at 62.3° F can be used to calculate the noise figure of an external antenna system.

Custom Products

Can I order additional calibration points for my noise source?

Yes. Please consult the factory, or your local representative for available frequencies and pricing.

Does Noisecom have custom solutions?

Yes. Please contact the factory, or your local representative for specific frequencies, power levels, or form factors.

Does Noisecom have GPIB & Ethernet drivers for their instruments?

Yes, follow this link to the National Instruments developers zone for all available Noisecom drivers:  http://www.ni.com/devzone/idnet/  and type “Noisecom”

Does Noisecom manufacture audio white noise generators for public spaces?

No. We manufacture RF and Microwave AWGN for telecommunication impairment and calibration standards.

Does Noisecom provide customer modifications to existing product lines?

Yes, Noisecom does provide custom solutions for existing product lines. Please contact Sales directly either by phone, or email.
