This is a 3.5mm to BNC adapter. You can hook any BNC probe to the 3.5mm connector of the Xprotolab Portable.
If you order two or more of these adapters for the Xprotolab Portable, keep in mind that you cannot put two of these on adjacent inputs, they are too wide and will not fit. You can order the 3.5mm to BNC converter cable instead.
CONGRATULATIONS for a great customer support. I am getting acquainted with my Xprotolab that I received day before yesterday. I tried the Live Support and it was EXCELLENT. Gabriel answered all my questions. I am a very happy customer. Tony Stepke ACS Consulting Company PO box 190 New Hyde Park NY 11040
