Hi Erik, as a further test, I turned off Channel Power and went to a normal spectral screen. As seen in the attached photo, all is now normal, the marker freq and levels are shown as well as the MK#2/MK#3 Delta. Apparently the Marker readouts are disabled when in Channel Power mode (and perhaps other modes as well).?

Ted,
? You have to take into consideration the purpose of the automatic Channel Power Measurement feature which is to measure the percentage of the total power in each band.? Since this measurement is integrated across each band, a single point marker reading is not really applicable.? This is pretty much standard for any? spectrum analyzer with an automatic Channel Power Measurement feature and not particular to the tinySA.
? If you are interested in a in only a single point power measurement then it is more appropriate to disable the Channel Power Measurement and return to normal swept measurements as you did in your second example.
? If you have a special need for measuring marker frequencies that you have turned on while in the automatic Channel Power Measurement mode, and you are connected to a PC, you can read the marker frequencies and level in dBm using the
marker?console command.? As an example,
marker 1 should return info in the following format,??
