Re: New Chat: Question: Understanding a scope probe #chat-notice
Can we please use the normal message board, and NOT chats? A bit confusing.
To OP Henry:
VTVMs had various Zin and probes, some had different Rprobe in AC and DC inputs.
Best ref for scope probes in general:
Tektronix Circuit Concepts "Oscilloscope Probe Circuits Concepts" everything from passive/active/Zo, DC-many GHz.
Worthwhile to have the printed booklet.
