Re: A technique for testing a DUT with reduced power


Thanks for sharing - I had plans to do this very same thing for testing bandpass filters that utilize a LNA, so as to prevent overloading. My interpretation of the effect shown with the attenuators added, is the detected result appears to be down closer to the noise floor of the device... not a major game changer - you can still get the results you're looking for when testing for the cutoff of a bandpass filter, or similar device...
