Tool/software:

Hi team,

My customer had a couple of questions regarding EMI testing with this device. Can you please help answer them?

1. Is radiated EMI measurement data available at the ~500MHz range, preferably up to 1GHz? Looking for CISPR 25 compliance

2. How to measure percentage of variance from the center frequency when spread spectrum is turned on?

Thank you in advance!

Hi Andrew,

Thank you for sending that over to me. Are you able to comment on how they can measure the percent variance from the center frequency in terms of the frequency range spread spectrum is affecting?
