Using the latest release of PS 7 T&M, on a M1 maccbook pro, MACOS Sonoma 14.6 , PicoScope 2204A

Using the Channel Options Invert function I notice that it stops inverting at sample rates of 2us or faster. Is this expected behavior?

This occurs when the number of samples across the screen drops below 2000 and the software switches on sin(x)/x interpolation which you will see in the Timebase button with the number of samples in a bracket. This has been reported to the development team.

The work around is to use a Maths Channel for invert rather than the Channel Option.
