Hello miyagi, many thanks for sharing your result and congratulations to enjoying good tool. Your scope show now SDS2504X Plus, while other methods result in SDS2354X Plus. Please do you have a possibility to measure your scope fastest rise time, and/or the frequency response?
Some owner share 650ps to be reached with SDS2354X Plus and Leo's pulse generator, or 600 to 650MHz -3dB bandwidth. Of course, with only one channel active of the pairs 1+2 and 3+4.
Would be interesting to know, whether there is still headroom in above values.
Once again, many thanks
