Zmod Scope input filters

[Todd-Kairos]

I see that the Zmod Scope 1410-40 has been deprecated (max sampling rate of 40 MHz), but the 1410-105 and 1410-125 variants are still available (max sampling rates of 105 and 125 MHz respectively). I'm considering switching to a board that is capable of a higher sampling rate. I suppose these boards each have different input filters, tuned relative to their respective maximum sampling rates? Or do they all have the same input filtering regardless of sampling rate? The answer will determine whether we need to add an external filter to achieve the same performance when switching board models.

Thanks.

Hi @Todd-Kairos

Beside the ADC speed grade, the Zmod Scope revC 40 had bandwidth, one capacitor value difference from 105 and 125 variants.
The newer revD 125 uses a different amplifier on the input stage, due to parts availability, EOL.
