  • Resolution: An expanded meter scale that enables resolution to a few hundredths of a dB
  • Range: Selectable offsets provide full scale ranges 0, 3, 6, 12, and 18 dB preserving the high resolution for most noise figure measurements
  • Dynamic Range: Will provide accurate measurements over an input signal level window of better than 65 dB
  • Level Indicators: LED indicators provide a positive indication that the input signal level is within the instrument's dynamic range
  • ENR Calibration: Permits the user to calibrate the instrument directly from the front panel for a noise generator ENR range of 14.0 to 16.5 dB
