Hi Bob It's certainly very much from the same family, these seem to be a couple of years more recent but obviously aimed at the same spec, and I don't doubt they're going to behave in basically the same way, but given that such things are firmware driven that doesn't exclude possible quirks. By way of example, I'm running this on an indoor antenna right now, not bad but satellites do drop in and out, and at times I'm seeing very noticeable step changes in the DAC voltage on this one as that happens. Warren S has commented on this with the Thunderbolt so it's no great surprise but I am a bit surprised by the extent, a Mark Sims online plot from 2012 shows some correlation on an NTGS50AA but not as noticeable as this, and I don't recall seeing anything quite so pronounced on a Thunderbolt. Similarly, other than scaling, the DAC voltage on PPS plots are just about identical. Again not a problem, but I was just curious to see if anyone had compared the two side by side.
