I am having trouble measuring the amplitude of a 97 MHz signal with an oscilloscope with a bandwidth of 100 MHz

First, I designed a Colpitts oscillator with a frequency of around 94-97 MHz. I added a common emitter amplifier to the design to increase the output amplitude of the oscillator, then I connected the ...

What does the bandwidth of a probe mean?

For example, when I have the P2221 ( http://www.farnell.com/datasheets/1808826.pdf ),The bandwidth when setting it to 1x, would only be 6Mhz. Looking at the input resistance and input capacitance: \$ \...

Is this a good design & layout of an active differential 'scope probe?

This question is an extension of Homebrew differential 'scope probe. I thought I should make this a new question though. I need to measure a 100Mb/s LVDS signal to check its integrity. I will try to ...
