I have a strange behavior of my pico scope 5444b. I was measuring a 16MHz SPI signal. The lines looks like bandwidth limited to 1MHz. With a cheap 5MHz limited scope the signal looks much better. On a Test with a function generator i could observe the same behavior (BNC to BNC connected). Rise time of the signal is about 18ns. With a 10:1 probe the signal looks better but still not good (rise time of about 8ns).
What can I do?
