The First One - The world’s first RF multimeter

 Powerful Features
  • Test frequencies up to 3GHz
  • 1Hz stepping over the entire frequency range
  • >110dB dynamic range *
  • Tracking receiver & narrowband detection
* in accordance with Technical parameters

Main Features
  • Transmission test (tuning diplexer and filter, testing amplifier and inspecting the directivity of antennas)
  • Reflection test (examining quality of antenna system and feeder system, a tracking receiver is used to improve the noise performance)
  • Spectrum display and field strength detection (inspecting radio frequency emissions / searching interference sources)

  • KC901H is designed for debugging RF devices, such as diplexer, filter, amplifier, splitter, combiner, and testing standing wave of antennas and insertion loss of feeders.
  • To test a transmitter or receiver, add external attenuator to extend input power range
  • Perform field strength measurement and interference detection in most frequencies.
  • Detect the fault point of cables / speed factor measurement.

A standard packing includes:
  • KC901H
  • Charger
  • Strap
