RCA 9TC240 Alignment...The start of my education (I hope!)

I think you misunderstood. The TinySA is a sweep source. You set the start & stop frequency and sweep rate and it outputs swept RF. Newer versions also output a trigger pulse to sync your scope.

What it does not have is markers. For that you can use a second RF generator and loosely couple it at the injection point.

I think it is a great option for an accurate, easy to use sweep alignment tool.

My main issue is the small size. If I were using it regularly, I'd opt for the much bigger and more capable tinySA Ultra. I believe it can output two frequencies so it might be possible to sweep one output and use the other for a marker.

(edit)
Took a quick look at the specs. https://tinysa.org/wiki/pmwiki.php?n...calDescription
The second output is for calibration and only does 30, 15, 10, 4, 3, 2 or 1 MHZ

So perhaps use a TinySA Ultra for sweeping and TinySA basic for the marker (or any other RF generator for that matter).
