Deepace KC901V 6.8GHz Handheld Network Analyzer Review, Teardown & Experiments

In this episode Shahriar reviews the Deepace KC901V 6.8GHz handheld network analyzer. This battery-powered instrument is an RF multi-instrument integrating VNA, spectrum analyzer, field strength meter, and a low-frequency signal generator. It can also perform signal port vector measurement and 2-ports simple vector network analyzing (S11, S21). The review is organized as follows:

01:24 – Instrument overview & block diagram.
05:36 – Full teardown along with RF and digital board analysis.
14:30 – Power on, calibration and S11 measurement of an antenna.
23:46 – Calibration for S21 and measurement of a tunable filter plus phase shifter.
32:23 – Distance to fault measurement of an SMA cable chain.
36:24 – Spectrum analyzer measurements and limitations.
43:16 – Signal generator measurements and issues.
48:20 – Other features and concluding remarks.
50:07 – Giveaway!

    Excellent video- thank you for all that hard work and very informative information.

    My unit has not yet arrived but after seeing this, I can hardly wait and have a very good idea of what to expect.

    You did an excellent job and all those hours of work are much appreciated.

    Best Regards,

    In the video you mention that this is not a “full” 2-port vector network analyzer but do not qualify that beyond pointing out that it does not have sufficient mixers. I am curious to know what is the missing measurement functionality that one would normally expect in a 2-port VNA ?
