mete Posted January 6, 2022 Share Posted January 6, 2022 I wonder the purpose of the series resistor on the signal wire on the high speed probe. Is there anything I should be careful about when probing with them ? Link to comment Share on other sites More sharing options...
0 attila Posted January 6, 2022 Share Posted January 6, 2022 Hi @mete The embedded resistors in the HS probes are to reduce the signal reflections that could cause oscillation/ringing. Link to comment Share on other sites More sharing options...
0 mete Posted January 6, 2022 Author Share Posted January 6, 2022 Thanks @attila, does the probing point make any difference ? or in other words, is there a case it could be better to use a normal probe/without the resistor ? Link to comment Share on other sites More sharing options...
0 attila Posted January 6, 2022 Share Posted January 6, 2022 Hi @mete The high speed adapter/probes are important above 100MHz sampling, for signals above 50MHz or for phases below 10ns. The twisted wires are useful to reduce crosstalk. https://digilent.com/reference/test-and-measurement/digital-discovery/reference-manual Link to comment Share on other sites More sharing options...
