Noise Generators and NPR Tests

Noise Generators and NPR Tests

Applied Instruments Inc. has a range of Test Signal and Noise Generators to assist organisation in the field and in the lab to verify quality of transmission lines and circuits delivering an agreed SLA.

The NS-3 Broadband RF Noise Generator provides an extremely flat AWGN (Additive White Gaussian Noise) signal from 5 to 2150 MHz. The output level adjusts in 0.1 dB steps over a 30 dB range.The bench-top configuration is standard and an optional two unit rack enclosure is available. The RS232 or USB remote control interface simplifies its use in automated test and factory ATE environments. The NS-3’s combination of range, versatility and value make it the ideal general purpose broad-spectrum signal source for bench and ATE applications, including C/N, BER, MER, PER testing and rain fade simulation.

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.

RF Noise Generator for Testing and Aligning 

 


 

 

 

 

 

 

It generates a wide, flat, RF noise-signal. The NS-1 is popular for testing network components and aligning a building’s coaxial cable network.The NS-1’s signal is injected into the network at point A. Using a signal receiver, such as a signal level meter (like Applied Instruments’ AI Turbo S2) or spectrum analyzer, the NS-1’s signal is received at point B. The frequency response of the network, between points A and B, is obtained. This measurement allows the user to verify the integrity of cabling and its associated connections at all frequencies between 5 and 2150 MHz.

Additional information on the NS-1 can be found in the Datasheet that can be downloaded from above.

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.

For HFC Active Components the NPRT 2200™ comes in a compact two-rack unit enclosure that is well suited for laboratory and factory ATE production environments. The NPRT 2200’s low cost and unsurpassed accuracy provide an unprecedented value.
