Can I change x-axis unit for Viva PSRR plot from Output setup?

Hi,

I run xf analysis to get PSRR, but I do not sweep vs frequency as usual, but vs a voltage. However, Viva x-axis unit is still "Hz". How can I change this, best permanently and only for this specific plot output (because I have also psrr vs f in another test).

Bye Stephan

    Stephan,

    I don't see this behaviour (and I find it surprising) - I am not seeing units at all if I sweep a design variable, or if I sweep a voltage source, the x-axis is in V, or a current source it's in A. I had a small problem that the direct plot form didn't seem to work - nothing got plotted (I need to check this) but plotting from calculator functions or the results browser all worked fine.

    I suggest you contact customer support - maybe there's some specifics in this case which are causing this issue.

    Hi Andrew, thanks for your great effort. I found a mistake in my setup. With sweeping of a variable I got now no unit, which is reasonable. The mistake was in the analysis setup: frequency vs variable. Frequency was set accidentially.

    Bye Stephan
