NPRT 2200 Base Unit

NPRT 2200™ (5 - 300 MHz) Return Path Noise Power Ratio Test Set [Datasheet] * [Operation Manual] The NPRT 2200™ measures the NPR of a device across a range of power levels.This test quantifies intermodulation distortion and determines the dynamic range of optical transmitters, amplifiers and other active HFC network devices.The included PC software uses predefined test setups to run a “Power Sweep” series of NPR measurements and graph the results. The measurements are compared to a threshold value to determine the acceptable operating power or dynamic range of the device. Results may be stored on the PC for further analysis and the graphs may be printed. The NPRT 2200™ inserts calibrated levels of White Gaussian Noise (WGN) through a Device Under Test (DUT), and then measures the noise level at a frequency where a notch filter is located.The NPR is the ratio of the output power without the notch compared to the power with the notch filter.
