I have a 5203 scope that I am happy with and I like the picoscope program. I have used it for 3-4 years now.
For my current project, I need to measure noise in the 100MHz-200MHz band. The noise floor of the 5203 is a little too high, to be effective in this project.
I know that you have developed a number of new scopes since I bought my 5203. Are there any of them, which was a lower noise floor, and also has a sample rate of 500 MHz or more?
