I got some more probes recently. Decided to test them like the other one.

The Setup:I used a noise source to generate a signal from DC to 500MHz. The impedance of the source being 50Ohms, a 50Ohms Terminator was connected directly on the output of the noise source. The probe under test was connected to the termination with a bnc-to-probe adapter. The other end of the probe was connected to an Oscilloscope (Lecroy WavePro 960, 16GS/s, 2GHz bandwidth).

Lecroy PP005, 500MHz probe:I must say I'm really impress with this one. I was expecting a lot worst, but the PP005 is a really good passive probe.

Tektronix P6046, 100MHz differential probe:Please note, this is not really a fair comparison since I had to use the probe in a single ended configuration (not differential) Nevertheless, the impressive part is that this probe has a 100MHz bandwidth at 1X.
