Description
Currently, we're sampling with 50 MHz and the target is running at ~5 MHz for ECDSA captures to keep a 10x oversampling ratio (some of this work is not yet in the repo). Above 50 MHz it seems the synchronization between multiple runs/segments is lost. We should re-investigate this with an updated Husky firmware.

Research direction
Start by reproducing ECDSA captures above 50 MHz with updated Husky firmware, comparing synchronization across multiple runs and segments. Done when higher sampling rates retain synchronization while preserving the intended oversampling relationship for the approximately 5 MHz target.
