Return Path Noise Power Ratio Test Set
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. A graph of NPR versus input power
illustrates the linear dynamic range and intermodulation distortion
characteristics of the DUT.
Our NPRT 2200 performs the measurements outlined in the SCTE 119 spec,
but in an easier and more automated manner. The NPRT 2200 maintains
constant total power with notch in and out. And with the included
NprGraph program on the PC, the measurements are automatic and the
program plots out the curve and calculates the dynamic range.
