Hi,
I'm looking for some (technical!) information on the HP E2447AA or
E2447AB probe pod (for using a HP logic analyser to monitor a 68000 CPU).
I need to probe a DIP64 packaged 68HC000, but the E2447AA/AB are for PGA
parts. So I figured I'd make a "top hat" PCB to adapt the 68k to a bunch
of HP transition headers.
The E2447AA delays the UDS and LDS signals before passing them to the
analyser. Does anyone know how much of a delay is introduced compared to
the original signal?
Thanks,
Phil.
