Service & Support

Noisecom can provide NIST traceable calibrations that include certificates.

Noisecom will provide both initial (if applicable) and final data on all calibrations.

Noisecom recommends a calibration cycle of one year on all equipment under normal usage.

Yes, Noisecom can calibrate and repair other manufactures devices. Please contact Noisecom sales for pricing and product availability for this service.

Noisecom warranties all new products to be free from defects for a period of 1 year.

Repairs have a six months warranty.

Outside the United States you should contact your local distributor, found here. When a unit is returned from outside the United States the customer is responsible for all shipping charges (incoming and return) as well as all custom fees and duties.

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.

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.
