White Gaussian Noise Generator – WGN Series
-
The WGN outputs very accurate, high quality white Gaussian noise. The output level can be set as Noise Density or Noise Power in a selectable bandwidth. Factory calibration over the entire frequency range yields 0.25 dB absolute accuracy. The noise power can be varied with 0.015 dB resolution over a 60 dB range. A user supplied signal can be injected into the instrument to combine with the noise. The instrument utilizes dBm‘s proprietary microprocessor controlled attenuator with 0.015 dB resolution, providing an extremely accurate output.
Applications
- Bit error rate and SINAD testing
- Modem and receiver characterization
- Channel impairment tests
-
- On/off control of both the signal path and the noise output
- 60 dB noise power range, typically -103 dBm/Hz to -163 dbm/Hz
- Frequency range 100 – 3000 MHz
