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). |
I understood. A Network Analyser has a calibrated scale display incorporated so that you do not need markers. The precision of the scale is the limiting factor here and I do not think a separate marker source is the answer. More expensive Network analysers have the precision. The cheaper device I suggested the software client may provide sufficient precision to negate the need for a separate marker.
The HP8600a/HP8601a combo sits in between a more modern and expensive Network Analyser and the older sweep gen/ marker solution but is much more efficient. It's versatility is you can use it as an accurate signal source which can be AM and FM modulated. And than be quickly switched to sweep mode with up to five markers with the flip of a few switches.
I shall purchase a Tiny SA as I would like to explore it.
