VSWR-Plot interrupted


 

Hi Rune,
I tested a BP-filter and I am wondering why the VSWR plot is interrupted. If you take a look at the attached screenshot, there is no VSWR line from about 268MHz till 846MHz. A tested LP-filter shows a similar symptom.
Would you please take a look at it?
Did anybody of the group see similar VSWR plots?

Kind regards
Norbert, DG1KPN


 

Hello Norbert,
thank you for trying out the software! The VSWR plot is set by default to
only show values up to a max of 25 - and the "draw lines" command isn't
*yet* clever enough to draw a line to a point that doesn't exist :D So for
that reason, it shows as interrupted, because the values are far too large.

If you set the VSWR data axis max to 100, it should draw bigger values, if
I recall correctly.

It's a feature, not a bug! .. but I'll probably fix it anyway ;-)
