If any of you have any expirience with PC-based PCI/USB oscilloscopes which are student-affordable, please share as well. Ideally, it would be a hardware being able to measure signals up to 50-60Mhz. I did however a bit of Googling and this was one of the most interesting devices: http://www.pctestinstruments.com/ Unfortunately, this product works only under Windows and the company's response about any kind of support for POSIX-compliant systems was *very* strong "NO". They claimed they have several clients working with their product under Wine and VMWare. -- Wojciech A. Koszek wkoszek@FreeBSD.org http://people.freebsd.org/~wkoszek/
