The measured level is about 2.5 dB below the actual input level.  The markers are not accurate.  It measures, for example, -2.5 dBm at one point but when you drop the marker to a point where the level is -80 dB, it will still measure about -2.8 dBm.   While turning the knob to move marker, frequency, amplitude, etc., the value jumps back and forth.  For example move the marker up with the turn knob  will cause it to jump back and forth to lower frequencies then higher frequencies back to lower...  This makes it very hard to get to the frequency you want to reach.  There is a spike at 10.09MHz that never disappears at a level of about  -69 dBm.  The buttons on the unit need to be pushed pretty hard to make them do anything.  The noise floor gets pretty high at the higher frequencies.
