Unable to measure frequencies beyond 9.6MHz

Post by Arjun »

Hello,

I have the 2205A picoscope and I am trying to measure the frequency that I generate using the SI5351 breakout board. I have been having trouble measuring the frequencies above 10Mhz that I generate using the breakout board. I can assure that the breakout board is genuine. I am able to measure the frequencies that are below 9.6Mhz, but when I program the breakout board to generate beyond 10Mhz, the frequency saturates to 9.6Mhz. I am using the analog channel A and I have kept the probe's slider in position X10. Can you please let me know what the issue could be?

Hi Arjun,

Could you post a psdata file of the measurement, and an image, or images of how you have set everything up. Also, where did you get the SI5351 breakout board from, and how are you controlling it?
Regards,
