Meet my new friend the logic analyser!

Its time to step my game up. So I've decided to acquire the immese value for money Saleae Logic Analyser. This baby will allow me to analyse and record a bunch of stuff that really cant be handled with a sound card and an oscilloscope alone. (namely serial digital audio prior to being sent to DACs)

As a test to see if everything works, and that i can get sufficient time resolution on this, ive done a simple setup which consists in a 4Mhz clock and a Hex inverter (74LS04). I done my recording test using 24Mhz on my MacBookPro's USB2 port. And im quite happy with the results. Not bad for 15 minutes of unboxing the thing!
