P3 VGA Question

[Elecraft mailing list]

I know the resolution is better on a VGA monitor than on the original P3 display. I also know that the VGA monitor has more pixels in the horizontal dimension than the P3. However it is obvious to me that the digital processing for the VGA provides much better resolution than the P3. My question how it is done? Does the VGA FPGA have more bins?  Or some other SDR/display design?   Thanks, Doug K6JEY

Hi Doug,

The P3/SVGA board does its own 2048 point FFT on IQ data that is passed down from the P3 front panel. The sampling rate is the same for either the P3's LCD display or the SVGA.   There's also a bunch of black magic to take care of things like fixed tune and receive path gain calculation.  

Kindly,

Paul
