Can you believe that?The world’s first RF multimeter !
——KC901H (the world’s first RF multimeter) network analytical rf multimeter
"One size fits all",as this honour,KC901H is one kind of all-round instrument that can be fully used in many types of radio-frequency test, what’s more, it is the world’s first RF multimeter.
KC901H is a radiofrequency multimeter,which is a scalar network
analyzer with field strength meter, signal generator, spectrum display and other features built in, for spotting and solving various kinds of problems on field for RF technicians and enthusiasts with maximum usability and portability.With carefully designed PCB and high quality components, KC901H comes with a reliable but cost reduced metal enclosure, which makes it a reasonably priced instrument without sacrifices on performance and functionality for Radio Amateurs.

Figure 1: the appearance of KC901H
We scale back part of the inputs such as appearance, while spare no expense in the design of the circuit part, which not only increases the practicability of the instrument, also makes it possible for everyone to afford the price.
Compared with the same type of device, KC901H is the first and the only product that is less than thousand dollars currently, however, its performance and quality are as wonderful as the best and high cost products in the market.
Highlights
- Test frequencies up to 3GHz
- 1Hz stepping over the entire frequency range
- >110dB dynamic range
- <3dB uncertainty
- Tracking receiver & narrowband detection
Main Features
- Transmission test (debugging 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)
Applications
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.
By properly increasing the number of external attenuator it can also be used to debug a loop of RF transmitter and receiver.
Perform field strength measurement and interference detection in most frequencies.
Detect the fault point of cables / speed factor measurement.
Example
Figure 2: Rocket fan finds a beacon through the directional antenna( tgo in Inner Mongolia, YT-4 rocket lanching test)
In professional communication engineering, radio and television transmitters maintenance and so on, KC901H is often used to measure the standing wave of antenna, check the feeder and debugfilter.
Of course, it also can be used to measure the field strength,detect and evaluate the coverage. As for radio amateurs, it is a long story for application,they will play out a lot of practical usages cleverly relying on the basic functions of KC901H.
For example, if grafted in after the probe, we can detect each section of the RF circuit, and if connected to a directional antenna ,we can locate the source of the disturbance signal.
As KC901H becomes more and more popular among radio amateurs, many friends experience the process of objective and quantitative test the first time,and truly feel that analyzed with instrument is of vital importance to improving quality and efficiency of DIY.
