Dave investigates how the front end bandwidth limiting works on the Rohde & Schwarz 1202 series oscilloscope. Is the bandwidth limit set just by the LMH6518 front end Variable Gain Amplifier chip through the SPI bus? See the extended 50 minute version here that has much more detail and mucking around trying to get the R&S1202 to probe itself. https://www.youtube.com/watch?v=HiqtXdK1Dtk Forum: http://www.eevblog.com/forum/blog/eevblog-879-rs-1202-scope-bandwidth-hack-investigation/ EEVblog Main Web Site: http://www.eevblog.com The 2nd EEVblog Channel: http://www.youtube.com/EEVblog2 ... https://www.youtube.com/watch?v=3THvWEKGOwE
