The CNG-1-26/180 is a noise generator from dBM. A noise signal generator is a type of electronic test equipment that produces a noise, or random signal, to test an electronic product’s frequency response, noise figure, and other important parameters. Pink noise is a random signal that the generator filters to have an equal amount of energy per octave.
- C/N, C/No, Eb/No, and C/I modes
- 1 or 2 independent RF channels
- Continuous input power monitoring
- Uninterrupted signal path during calibration cycle
- IEEE-488.2 interface
The dBm CNG-1-26/180 is a complete line of fully automated carrier to noise generators that sets and maintains a highly accurate ratio between a user-supplied carrier and internally generated white Gaussian noise. The instrument operates over a wide range of power levels and are compatible with both digital and analog modulation formats. The modular design of the CNG provides one or two totally independent RF channels to allow simplex, diversity or duplex testing. Precise carrier-to-noise (C/N) or carrier to interference (C/I) ratios may be programmed and the CNG will measure the carrier signal and accurately adjust the power of the internal AWGN source to maintain the desired ratio. The dBm CNG-1-26/180 IS available for Cellular, PCS, CATV and SATCOM test applications.
