1GHz active probe project feedback

<< < (5/5)

lasmux:
And we're back to 1GHz bandwidth, with about 1.05pF input capacitance (150Ohm load at 1GHz).

riscy00:
I doing the active probe thing to do, can you share your schematic? thanks

jonpaul:
At 1 GHz much simpler to make passive Zo probe at zero cost...

50 Ohm coax><BNC cable

Place 450 or 4950 Ohm 1/4 or 1/8 W avial R in series, probe with end of R.

Use on 50 Ohm scope.

10X or 100X cant blow up, BW can be 2..4 GHz.
