Hi Justin,
thanks for your answer.
So turning off the image/spur rejection will not solve the problem?
And if I set the VBW to 1/10 of the RBW and measure below 42MHz (I measure from 20 to 40kHz or 60 to 100kHz) I dont have to substract 3dB from the measurement.
I will try it with the SA44B at first.
