I am working with an STM32F405. Planning to use Segger J-link probe and J-scope combination to visualize RAM variables over the JTAG/SWD/SWO interface. does anyone know what is the maximum sampling frequency I can achieve with the STM32F405?

Segger quotes the J-link Ultra+'s target interface speed at 50MHz and an "unlimited sampling bandwidth, limited by the bandwidth of the debug interface"... Ideally I would like to plot 4 floats at atleast 10kHz sampling rate.

Sounds like something you'd discuss with Segger's sales/support reps

Got a more utilitarian approach here, saving data to SD Cards, or plotting via attached LCD or monitors.
