E5071C - constant VSR circle "overlay" possible?

Hello

I'm imagining that, via a VB macro or possibly a CSV import, it should be possible for me to construct a constant Z circle on the Smith chart for VSWR = some value (e.g. 2, 2.4, 3 etc. to correspond with typical return losses).

I don't know how to program VB macros and I don't know if that approach would be pertinent. please couold someone suggest (a) is this possible and (b) how might I go about it?

It doesn't have to function as a limit line - just a visual reference so I can see how much of my locus is wrapped up (inside the e.g. VSWR=2 circle). A fixed circle (VSWR=2) would be fine, an adjustable one (user selects from three fixed values for example) would be even nicer.

Thanks for any help on this matter

Simply create an S1P file with in MA format with constant M and A varies from 0-360 degrees over your span of interset. Import the S1P file and there you have it.
