Value-Added Engineering
NWS possesses unique knowledge in the design of high capacity systems for the delivery of video and data information. The accumulated knowledge of every project NWS has worked on since 1984 is refined and transferred into your project, thereby increasing the total value of your system beyond the price of its components.

Our commitment to testing offers a good example. When building a client's head end, NWS quality assurance and testing practices incorporate rigorous test procedures:
  • Spectrum Analyzers are used for signal level, 2nd and 3rd harmonic and spurious emission content, carrier to noise ratio, head end system tilt and balance measurements. The spectrum analyzer is also used for aural carrier deviation, EMI (electromagnetic interference), and ingress measurements.
  • Strength Meters are used for detecting system levels/balance/tilt at either the head end or at the final cable drop to achieve proper signal level. System levels reaching the end drop will be within 0 to +10 dBmv and have a carrier to noise level greater than 48dB, and conform to CATV standards set forth in the Code of Federal Regulations.
  • Calibrated Precision Demodulator is used for demodulation of the CATV video signals, calibrated to NIST traceable standards.
  • Waveform Monitors and Vectorscopes are used for measuring the quality of the video demodulated by the precision demodulator.
By performing these tests on all NWS integrated head ends, NWS ensures superior picture quality and data transfer rates.
