Main Features

  • Vector network analyzing up to 20GHz
    1Hz frequency step
  • Good accuracy and anti-interference ability
  • Abundant functions and easy to carry

Main Functions

  • Transmission measurement S21(Filter adjustments, measuring amplifiers, verifying
    directivity of antennas)
  • Reflection measurement S11(Impedance matching network adjustment, antenna
    feeding system quality evaluation. Except for the KC901Q, which requires an external coupler to measure S11, the coupler can be purchased separately.
  • RF source and audio signal source
  • Time domain reflection(DTF) measurement
  • Limited Spectrum display and field strength observation

Recommended Applications

The KC901 is mainly used for adjusting various RF circuits, such as filters, amplifiers, splitters, combiners; testing input/output impedance, evaluating antenna feeding system and detecting equipment’s signal amplitudes at all levels. It can also do field strength measurement, which is useful for checking  the correct operation of low powered devices with integrated antennas and when searching for interference sources etc.
