#142422 - MSC1211- probe
Responding to: ???'s previous message
I am not sure what you mean by a properly tuned prob.I am using
LeCroy
PP007-WS
/10
500 MHz
10Mohm 9.5 pF

probe.

I am also seeing the exact same thing on the EVM. so either both are fine or I am doing something wrong on both! but my board doesn't do anything. again the downloader doesn't complain but nothing changes...As in the PSEN is still outputting althought the program doesn't set it to.

I really appreciate any thoughts on furthur debugging directions.

thakns,
vida
