Noise Power Ratio Test Set
The NPRT 2200™ measures the NPR of a device across a range of
This test quantifies intermodulation distortion and deter- mines 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. A graph of NPR versus input power illustrates the linear dynamic range and intermodulation distortion characteristics of the DUT.
For HFC Active Components he NPRT 2200™ comes in a compact two-rack unit enclosure that is well suited for laboratory and factory ATE environments. The NPRT 2200’s low cost and unsurpassed accuracy provide an unprecedented value.
