Hi Bruce,
?
I use a large wattage attenuator followed by a lower wattage step attenuator. ?The first is sized for the max power I plant to test (either 50 or 100 watt, 40 or 50 dB). ?This allows me to adjust the level for best accuracy and to validate that the SA is not suffering from signal compression.?
You will most likely spend more on the attenuators than the tinySA if you are going to measure anything over 10 watts.?
example of 2 watt step attenuator:

I use one like this after a 100 watt 50 dB fixed attenuator?
