Why didn't you show CISPR results up to 2GHz?
Why didn't you show CISPR results up to 2GHz?
On behalf of David Carr:
We did test up to 2 GHz since the internal switching frequency of the product is above 108 MHz and below 500 MHz. Above 1 GHz the performance is well below the limits so we focused on the 30 MHz to 1 GHz band in the webinar. In this frequency range there are tighter limits and the fundamental switching frequencies and harmonics fall in this band. Most of the power is contained within these harmonics. We can provide plots showing performance above 1 GHz if that’s important for your application.
