Pspice measurement results

dirkoson

 Hello,

I have generate a bode plot. I want to get the gain value which is fallen to -1dB based on the gain value at 1kHz. I know I could take the cursors, but I want to take the measurement results.

For example 30.3dB at 1kHz and 29.3dB at x kHz.

I thought I can  take the function: bandwidth(1,dB_level) from the measurement results. I write Bandwidth(  DB(V(Uaus1)/V(Uein)) , 1 ) but I get no result.

 

Can everone help me, please?

Best regards

Dirk

     Hello,

    thank you for your answer and for the note, with the  YatX function. And you say, I should modify the YatX function. I have tried to create a new measurement expression, but it is not possible. I open Trace >measurement > New. Then I copy the data of an existing file, for example YatX an push ok. But there is no new Measurement. Can I only modify an existing measurement?

    Do you know sources, about this theme, that I can reading about this?

     

    Best regards
