KC901S+ is a multipurpose RF instrument integrating a VNA (vector network analyzer), spectrum analyzer, field strength meter, and an extra low-frequency signal source. It can do complete single port vector measurement and 2-ports simple vector network analyzing.

Main Features

  • Vector network analyzing up to 4GHz
  • 1Hz frequency step
  • Good accuracy and anti-interference ability
  • Abundant functions and easy to carry (Weight less than 1kg)

Main Functions

  • Transmission measurement (Filter adjustments, measuring amplifiers, verifying directivity of antennas)
  • Reflection measurement (Impedance matching network adjustment, antenna feeding system quality evaluation)
  • RF source plus an extra audio signal source
  • Spectrum display and field strength observation (potentially used for inspecting a radio station’s emission performance, or for searching for the interference sources)

The differences between the KC901S+ and the KC901S

  KC901S+ inherited the advantages of KC901S, and made great improvements.

  • The S21 of KC901S+ can measure phase and group delay.
  • The frequency range of the KC901S+ from 9kHz to 4GHz.
  • The flow direction of signals measured by S21 of KC901S+ are opposite to KC901S, the use of methods are exactly the same with the KC901V.
  • The accuracy of S11 has greatly improved.
  • Spectrum function of KC901S+ support 1, 3, 10, 30KHz RBW, 901S only support 7.5KHz .

Recommended Applications

  • KC901S+ 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 level. It can also do filed strength measurement, which is useful during miscellaneous kinds of search for interference source etc.
  • Combining intelligence in the community, KC901S+ is the tool to study RF for students and hobbies. In professional situations, it is used in communication engineering, antenna manufacturing, daily maintenance of broadcast, RF circuits development and so on. KC901S+ improves working efficiency, ease the weight burden and improve working quality.
