Gw Instek GDS2204E (200MHz 4 channel DSO) review
nctnico:
I have been wanting to do an interesting experiment for a while now to see if there is a (practical) limit to the SPI decoding speed. I had to wait though for an FPGA project to come along so I didn't have to build a test setup for one simple test. I created a simple SPI signal generator which just outputs incrementing values (LSB first) with an SPI clock frequency of 125MHz and fed it into the GDS2204E. It turns out it can decode and trigger SPI at this speed just fine even though the clock signal looks like a sine wave.

Nice job on the review.
MT:
Great review, from where did you say you bought it?
nctnico:
I got it from a Dutch dealer called Eleshop.nl

Pity that the review is mostly text, and hardly any screenshots!
