Using an active probe or FET probe is an effective way to measure high speed signals.
Even when using a passive probe, you can effectively reproduce waveforms with less ringing or overshoot by devising different ways to connect to ground.
Features
The PBL5000 low-capacitance "transmission line" probe (passive) features both 10:1 and 20:1 attenuation.
This probe requires a 50 Ω scope/termination and can be used with any oscillscope with a BNC input.
The change in attenuation is realized by changing resistance on the tip of the probe;
Can also be used with DC Block 701975.
For use with a scope which does not have a built-in 50 Ω termination, please purchase a 700976 50 Ω external (BNC) pass-thru terminator.
