Hi Valentin87,

 

Precise schematics are generally classified as NI Confidential.  Here is some public information which may help you:

 

https://www.ni.com/documentation/en/oscilloscope-device/latest/usb-5133/overview/

  • 40 mVpk-pk to 40 Vpk-pk input range
  • 1 MΩ input impedance
  • AC, DC and GND coupling

GUID-AAD006DA-C780-49B6-8DA6-9D32A4B3BCC6-5.5x8.5%20-%20a5

 

Sorry that this is maybe an oversimplified answer to your request.

 

If you can be more specific in your questions about the input circuit, I may be able to provide some more detailed answers.

The spec additionally tells :

Input impedance 1MOhm || ~17pf

AC cutoff 12 Hz (3db) ...

 

Hook up a NVA and you can measure all properties you migth need 😉

 

 

However a bit more documentation as can be found in other digitizer/scope devices from NI should be standard!
