USB-based Oscilliscope suggestions?
(OP)
Hey all
Sorry if this has been beaten to death, but I didnt see anything in my search on USB->PC oscilliscopes.
Most of my work is automotive, but sometimes I need to be able to tap in to verify phasing on stepper motors, or to look at a CAN bus, etc. Im looking for a relatively inexpensive and portable 2 channel (4 would be great, but probably too ostly) DSO. Absolute accuracy is not really a primary consideration for me (Im fine with +/- 10%), and I expect that 25-50mhz is adequate for fine detail on serial protocols like I2C. Im using a Fluke 123 now, which has only 512 data points, and that is far too limiting. Any suggestions? I saw a few models on Ebay in the $200 range, but have no idea if they are worth their weight in water.
Any suggestions or links to threads on this would be appreciated-
Regards,
Rob

Thanks, yes I found them yesterday doing some searching. Looks to me like they are in the $700-$1000 range though, and Im looking for something probably in the $300-$400 range if such a beast exists. I should have posted that, as the term 'relatively inexpensive' is pretty mushy.

A search on google for "USB ocilloscope" yields TONS results.

I have a Tektronix handheld that's really nice but not as nice as the $3500 price tag would imply.

I remember reading a review of several USB-based hobby-level o-scopes/DLAs within the last year, but I can't recall where... maybe Circuit Cellar Ink or Electronics Design?

That never happens to my LeCroy four channel 200 MHz scope. Also, the Pico Technology repair and guarantee policy leaves a bad taste.
I have been more lucky with my TiePie HS4. It is a four channel USB scope with a somewhat lower (can't remember now) band-width and higher vertical resolution, WS 424. It costs about same as the 3206, but has four channels. I use it a lot when travelling (laptop + HS4 + probes fit together in computer bag) and it has never let me down. The TiePie software is "new think" and it can do lots of things I never thought of before. It also has a very nice feature that lets you install many of them on one laptop (powered hub needed) so you can have a fast 12 or 16 or (perhaps even more) channel system at a very interesting price.
