Gordon, It would appear the AC coupling capacitor which has impedance enough at 150 KHz to cause 3 dB loss in the 50 Ohm circuit, but also that it's low enough R&S can warrant the receiver to meet published specs above 1 MHz. What does CISPR-16 say? Does a receiver have to be flat all the way down? One could easily "calibrate out" this kind of response in software.
