Be sure to be aware of your device's maximum permissible input power level (I'm not sure what it is for a tinySA). If measuring a 100W transmitter with an analyzer whose maximum input level is 10mW, you'll need 10 dB more attenuation - this could be in the form of a fixed attenuator on the output of the directional coupler. Or, better yet, just turn the transmitter down to a 10-watt (or less) output if using a 30dB coupler.
