Re: ADL5380 DSB NF Measurement

Hello HJ,

A standard agilent NF meter (like the N8974A) by its nature is measuring DSB.  In the case of the ADL5380 the DSB number of one channel (I or Q) is measured and reported.  Because the ADL5380 is an I/Q demod, when you take into account that the actual output is the complex I/Q output it turns out that the DSB number reported for 1 channel, is the same as the SSB number for the demod complex I/Q output.
