Hi all,
I want to measure the NF of a downconversion mixer with an IF of around 100 kHz. Can anybody reccommend equipment to do this? Currently I am using an ESA spectrum analyzer with built in noise personality (it uses the Y-factor method), but the analyzer is not designed to be used below 10 MHz (although it will output data). So i'm worried that the measurement results are far off.
Another method I thought of using is the gain method where I don't need a noise source. Is this method considered accurate for my application. The DUT gain is around 30 dB and the RF frequency is 2.4 GHz.
thanks, Aaron
