Hi All,

As title says i would like to know how to display dB vs frequency in orcad pspice. I have versions 9.2 and 10.3 but in both versions is seems rather difficult to configure the graph how i would like it.

basically i am designing filters and would like to display the relevant gains in dB at certain frequencies on a graph. dB on Y axis frequency on X axis.

If anyone can help that would be great.

Thanks

Andy
 

Dear friend

(OrCAD 9.2)
Setting: AC Sweep/Noise.
For example: AC Sweep Type= Logarithmic/Decade
Start Freq=0.1Hz, End Freq=2MegHz, Points/Decade=1000.

Go to Menu bar : PSpice/Markers/Advanced/dB Magnitude of Voltage.
Then put the VDB marker on the output node.

See an example:





Best wishes :D
 
Thank You, i knew there would be some way of doing it.

Points going your way :)
