Quote from aminucd on 31/07/2023, 23:45Hi,
I have a question regarding the RF mixers in use in SPECTRANV6 RSA250X. From the above schematics, I understand that IQ mixers have been used. I wonder if there is any mechanism (e.g. a 90 Hybrid coupler) to reject the frequency images from the mixer products. Do we expect to see the frequency images in the spectrum analyzer?
Thank you
