  * Frequency accuracy equal to the selected resolution bandwidth
  * Spur free dynamic range when using a 30kHz resolution bandwidth of 50dB
  * Manually selectable resolution filters of 3, 10, 30, 100, 300, 600kHz. Automatic selection of one of the 57 resolution filters.
  * Optional 25dB to 40dB frequency dependent input attenuator. The power level error with this attenuator activated increases to +/- 10dB
  * On screen resolution of 51, 101, 145 or 290 measurement points.
  * Scanning speed of over 1000 points/second using largest resolution filters.
  * Automatic optimization of actual scanning points to ensure coverage of the whole scan range regardless of the chosen resolution bandwidth
  * After a small HW modification it is possible to Listen to the demodulated audio
