Justin, Andrew,
This is still a problem. In fact, I can now reproduce it on two different SH units (SA124A & SA44B). Perhaps it could be the that the amplitude or the modulation format of the measured signal is affecting the measurement algorithm? My radio puts out +20dbm with a OQPSK signal. Your measurements above were made at -40dbm, not sure of the modulation. There shouldn’t be a difference, but there is. As stated earlier, I have verified my measurement with a Rhode & Schwartz spectrum analyzer at my FCC test lab. How do you propose we address this?
