practically speaking it is USELESS!!! it is completely uncalibrated and, even following the poor calibration instructions, doesn't help. and I am not talking of 1 or 2 dB but 10 and even more dB according to the frequency and the level of the incoming signal. in the attached picture you can see an FM video signal. the central carrier is the video one while the 2 lateral are the audio carriers, 6.5 MHz apart. at a RBW=100kHz the 3 are so distorted that it's impossible to analyze them! more over the 2 audio carriers seem to be some 28 dB down the video one: and that's not true! they are 15 dB down when measured with my spectrum analyzer!!! so this equipment is really useless and I am completely unsatisfied!
