Hacking a Tektronix Oscilloscope to1GHz!

Episode 50 #tektronix #1ghz #hack Lately I have run out of bandwidth, trying to measure signals from pulsed Lasers. My fastest oscilloscope was a hacked DS1054z at 100MHz, nowhere near fast enough to measure nanosecond pulses. I picked up a Tektronix TDS754C from eBay. This scope has a beautiful CRT display, and is already a decent scope, but bought it with the sole purpose of hacking it to 1GHz, and whilst I am at it, increasing the memory ;-) These hacks are pretty straightforward and effectively turn a TDS754C into a TDS784C, though there is a trap with rise-time measurement...
