Re: 8566 to measure 100W FM transmitter

Re: 8566 to measure 100W FM transmitter
I would take care in how you are sampling the signal. If you are concerned with harmonics of the transmitter, the sampling method might incur different losses at the fundamental than at the harmonic,

Re: 8566 to measure 100W FM transmitter
I would use a directional coupler such as a HP778D to get a 20 dB sample. Then pad the sample port with a 30 dB pad. That will get you to 1 mW into the SA. Note that the 778d is rated for 50 watts cw.
