Reply To: Preselection filters

Hi Justin,
Thanks for the reply.
I was looking at making a 250kHz wide adjustable BPF but that is way too tricksie. And making a switched version doesnt help, requires a massive number of filters…

So I’m just looking at breaking it up into the standard CISPR22 intervals with selectable HPF and LPF sections.

I looked at mini-circuits but that approach is going to add up pretty quickly.
I’d love a BB60C, however I cannot justify it for a personal purchase as it is compounded by the requirement for a new laptop too (to get USB3).
The office has shelled out for a NI VST but this is currently used in the factory for 3G radio compliance validation.
