A keen 8-station, transceiver-oriented RF testbed are build to check on the latest transceiver product line getting phased selection software
Counted Overall performance
The exam configurations having researching the brand new waveform machines is actually found in the Contour 4. For it take to, the same electronic info is applied to all the waveform generators. An excellent calibration is completed along the channels by the modifying the new NCO phase to guarantee the RF indicators come into stage during the 8-way combiner and you will coherently mix.
Within our review i located the third harmonic was continuously coordinated around the streams, the image regularity was continuously uncorrelated, while the LO volume varied dependent on start-right up conditions
Second we’re going to tell you try research contrasting spurious for the LOs and you can NCOs ready to go on the same volume vs. spurious when the LOs and you may NCOs was offset when you look at the regularity. The new transceivers used show a keen LO contained in this a two-route product (find Contour 1), very into the 7 RF streams there are five other LO wavelengths. (mais…)
