The NoiseCom UFX series is a line of precision broadband noise generators engineered to deliver white Gaussian noise across wide frequency spectra for signal jamming, testing, and calibration applications. Microprocessor-controlled instruments, UFX models combine compact design with stable performance and operate via front-panel controls or remote IEEE-488 (GPIB) command. Selectable frequency ranges span 10 Hz to 4 GHz across the product line, with output power up to +30 dBm and attenuation control from 0 to 127 dB in 1 dB steps (0.1 dB optional). A true RMS power meter accurately measures Gaussian noise signals with crest factors to 18 dB across a −55 dBm to +5 dBm range.
