I purchased a KC901S+ and arrived this week.
But S11 functions not working properly. Not showing S11 data (VSWR/RL/Pha/ Smit/Imped) Very small change with Port1. When I chose Sys cal/ Corr OFF.
Then I tried Func + Shift+7+ SYS recal. and SYS calibrated, then it will work almost correctly. But when I reset, again not work Sys CAL and not work in "corr OFF" selection also.

All other functions working correctly.
Spectrum analyzer working
Field strength working
RF source working.

What may be the problem ? It is return to you is very expensive and i need again pay customs duty. Already I paid large amount as customs duty.

If you can give me correct solution i can check here, because We have all service facility here for Hantek Oscilloscope and Spectrum analyzer and other product.
We have LeCroy 4Ghz DSO also for testing and calibration.
Please help me. very urgent.

    Save the cal data to a card is a good way to improve the instrument experience. we will try to do more development in software to make our instrument more easy to use
    Be of normal mechanical function
    Even the manufacturer knows this.

    Try it with a dummy load attached.
    50 Ohms

    I have the same device.
    Ask the manufacturer.If there is no log in the error list, it is judged normal.

    Yes, after my SYS calibration, it will work almost perfectly but if some one do "reset all", SYS cal will lose. again need calibration. SYS cal not saving to factory default. .
    Can you give me the link of kc901sP exclusive firmware ?

    KC951011 N type 6GHz OSL calibration kit.
    You can do it with another Cal Kit.
