Applications:
Noise sources are used for signal jamming/impairment and reference level comparison. They are essential in testing environments for measuring noise figure and gain, and for calibrating antenna power levels.
Noise Figure Measurement:
Accurate noise figure measurements require good match or low VSWR ratio between the noise source output and the DUT. Calibration is crucial for measurement accuracy.
Satellite Channel Impairment:
Performance of BER vs Eb/No is tested using precise bit-energy to noise-density ratios, with modulation and coding designed for noise-limited communication systems.
System jitter can significantly affect circuit behavior by altering transition timing and narrowing the persistence eye opening on test receivers, leading to higher Bit Error Rates (BER). Noise, although typically unwanted, can be used to introduce precise disturbances in high-speed data systems to evaluate component interoperability and establish a jitter budget. White Gaussian noise, resembling real-world interference, can be injected to create amplitude modulation (AM) or phase modulation (PM) jitter, affecting both amplitude (dV) and time (dT). Properly generated noise follows a Gaussian distribution and can be used to vary the Signal-to-Noise Ratio (SNR) in digital circuits, aiding in jitter budget establishment. Noisecom offers various noise injection models for jitter testing, including the J7000A series and NC1000 series modules.
Application Section: Antenna Reference Sources
All objects emit white noise proportional to their temperature, which can be measured remotely using a radiometer. A noise-injection radiometer compares the noise power from an object with an internal white noise reference source, eliminating errors due to gain variation and impedance mismatching. The effective noise temperature at the radiometer input is calculated and compared with two internal reference temperatures. Noisecom’s NC346 and NC5000 Series provide efficient white noise sources for these applications.
Diode
Noisecom’s noise diodes are essential for broadband noise generation with a flat frequency response. They deliver symmetrical white Gaussian noise and flat output power when properly biased. Available in various package styles, these diodes are suitable for audio, RF, and microwave applications. The NC100 and NC200 Series are for audio and RF, while the NC300 and NC400 Series are for microwave applications.
