No, I did not check the condition of the BATTLY
. If I turn the analyser off and pull out the power plug for a while then I still have the calibration. I assume if I can readout the resolution bandwidth calibration it is still working. What do you think of these values? About the noise level, yours is much better
. I have measured about -141dBm/Hz. During this noise floor measurement I observed an other issue. At a certain setting I saw repeating spurious tones in the noise floor and if I turned the marker readout off the spurious tones disappeared. Does this ring a bell to you Jeremy? Is this a problem in the display part? What I have mentioned before I have to check the analyser completely but that is a lot of work.
I have attached two pages out of the manual. You have to adjust the RF level in range, thanks.
