Title: Rigol Scope Probe to BNC Adapter
Post by: Electro Fan on May 11, 2015, 06:08:09 am
Anyone have a good source in the U.S. for the BNC to scope probe adapter shown at about 14:35 into Dave's video - that would work with a Rigol RP3300A (10:1) probe?  (Is the Rigol probe 3.5mm? 

Also, how about the banana plug binding post insert that makes the 90 degree banana plug to banana plug connection (also at 14:35)?

If you want to look at PSUs, "high" impedance is irrelevant: just use ordinary 50ohm cable terminated in 50ohms at the scope.

If you want to look at digital signals, use a  "low impedance Z0 probe" - which peversely has a higher impedance than so-called low impedance probes.

Bit of discussion on exactly this on the last page of this thread:
