Pasternack has extensively expanded their line of coaxial packaged noise sources that cover frequency bands ranging from 100 kHz to 60 GHz. They have various types of noise source designs available including octave band and broadband noise sources, amplified noise sources, noise sources with integral isolators, and precision calibrated instrumentation grade noise sources.
The new noise sources might generally be used as a reference source to measure system level noise figure for test and measurement applications. More specific applications could involve system and component level wireless testing, signal simulation, evaluating analog and DOCSYS CATV systems to improve the dynamic range of analog-to-digital converters by dithering and reducing correlated noise. Additional applications could involve simulation of RF jamming systems for missile guidance, use as a source for bit error rate (BER) testing for SATCOM and digital radio systems, and a source for Gaussian jitter for testing of optoelectronic devices.
With 30 different models, Pasternack's portfolio of coaxial noise sources boast a wide range of output ENR levels from 7 dB to 35 dB. The amplified models have output power levels ranging from -14 dBm to +10 dBm. Circuit board designs use packaged noise diodes and other discrete components that are tuned for optimum performance. Assemblies are enclosed in rugged metal packages with a variety of DC and output RF connector options. Most models in this family are designed to meet MIL-STD-202F environmental test conditions and all models are EAR99.
