[Boatanchors] Inexpensive Scope Probes

[Glenn Little WB4UIV]

While in the navy, we ordered a Tektronix scope probe.
Due to competitive bids and "specs" we received a knock off probe.
When I attempted to measure a clock waveform in a computer with the 
prescribed scope and this probe, the waveform would change depending 
on where along the lead you placed your hand or the position of the 
lead relative to the chassis of the computer.
The next order was specified "do not substitute" and we did receive a 
genuine Tektronix probe.
There was no problem measuring the clock waveform with this probe.

Buyer be ware with cheap probes.
Probably useable for audio, but very questionable above a few MegaHertz.

It all depends on how much you want to trust the waveform displayed 
on the scope to be an accurate representation of the measured circuit.

Just my experience.
I will only use quality probes.
