Ooh. Nice.

I looked closely at BitScope when I needed an oscilloscope. Although the design philosophy is great (open), and having mixed signal capabilities in one box is desirable, I decided that the specs were just too compromised to justify the price. You can do better with used brand name stuff on ebay - In my case I scored a TDS360 for an absolute steal.

The Ant16 doesn't look that much cheaper - it's only about $40 less but you lose 18 channels! The Ant8 is certainly cheap if you live with only 8 channels.

The two pen units are novel, but too limited for their price. Most of the time you want to analyse a signal with respect to another - and you can't do that with a single channel. The Ant8 is a much better choice than either IMO.

The Tech-Tools and the Intronix units both look to raising the bar though. Let us know how you get on with the new toy!
