Waveform viewer math

Is there a way to display waveform viewer math for the two cursor values? Examples would be to calculate delta T between two cursors, and also 1/deltaT…Useful for seeing the frequency of oscillation.

Similarly, nice to display deltaY…example, measuring the dB difference between first and second harmonic as displayed in FFT.

I’d guess it’s in there somewhere, but I didn’t spot it…

When you have two cursors, the delta value is displayed in the status bar when your mouse cursor is in the plot pane (black area). In Qspice, the last clicked cursor becomes the active cursor, and the delta is calculated as the active cursor minus the inactive one. You can move the active cursor using left and right arrow keys and the delta value will keep updating. (update Qspice to latest version as Mike just added this)
