Some good news again =)

I got to better control pulses (I need to really read more carefully  datasheets), got acquisitions at 64Msps, really looking good, and got some (badly formed at the moment) images!

Acquisitions - going to specs at 64Msps. Thanks David =)

Pulser: getting 200ns wide 75V pulses (blue is the pulse with a piezo on, in yellow is the 'damping' control signal.

Getting some images from a "damaged" probe

More on the log!
