DSO Nano peaking of input

H, I just got my DSO Nano v 1.3 three days ago

I have a question: The test waveform showing quite a bit of peaking. Why? (Capacitors C0, C5, C3A, C4A, C6A are not installed)



We have calibrated the capacitor on each DSO to meet most applications, but it might not be the exact match. If you need more precise measurement, you could adjust the capacitors further to get a perfect waveform.


OK, I understand. FYI these capacitors are traditionally adjustable in 'scopes, but understand that there is no room, and access to adjustment during test.
