      Hi again,

      I repeated the test with the slowest speed setting with the 3dB and 6dB attenuators in line before doing the calibration. I then took a picture of the display for the 4dB and 6dB stepped attenuator results as I previously did. It did not seem to make much difference.

      Hi.

      Thanks for the feedback. In the field strength mode ,the speed is set at medium and I thought it was for all the tests, but I can easily repeat it with a slower speed. I wondered why there was the kick at the start of the sweep and that might explain it.

      Please keep this suggestion for a software change under consideration. It helps avoid confusion when using AF and RF signal generator functions. The fact the unit defaults to generator off at times to save battery capacity is fine but the user needs to know that they should not be expecting an output. 54 days ago

      John,

      No problems. Strangely enough, the KC901V is helping me understand some limitations in my other test equipment as I go.

      I left out the picture of the added 3 and 6db attenuators.

      Lala land,
      OK, good observation and fair point. Ugly but functional works for me until I had something better.

      Post a picture of you wonderful workbench and you interesting testing with the KC901V and we will have something to talk about.
