    @henrik_stenlund I tried the SD card before and after the update and it worked fine for me. Maybe you should try a different SD card and see if it works?

    That is good to hear.

    I did finally get up the courage to try the update and it seems to work fine on my KC901V. Thank you for continuing to keep our product up to date and fixing bugs - M John Ellis

    I am having trouble with the V1.2.3 for KC901V while saving a measurement data to a microSDHC. That operation did succeed earlier but now it completely refuses. Please check

    it now can go down to 0 Hz which sounds good, but measurement error at this ultra low freq still not fixed so this feature is still rather useless, for example its still cannot show impedance of a DUT correctly (other than 50 ohm load), the same with magnitude and phase of gain and loss etc.. fwiw.. looking forward for the next FW update, thumbs up anyway..

    I'm always nervous about updates but the last one was a good one. Has anyone had a problem with this update?
