    This is probably the dumbest question in the world, but I am a PSpice dummy!! I am trying to simulate a 2-pole low pass filter in Orcad 16.0 Lite, and I have gotten the schematic to work, and a nice Bode plot, but I need the calculated data (the calculated Vo magnitude and the calculated Vo angle). How do I make this data table appear??? I have entered my cutoff frequency as measured as a range (9 Hz to 9kHz). Our book says use "VPRINT", but I can't find it in the part library. Any help is greatly appreciated!:confused:

    you can add a trace to the chart. either on the tool bar or through a right click.

    Thank you! So, if I add the trace, it will show me the data? Where do I find the VPRINT marker?

    you can add a trace and then save the trace to a data file.

    how to read that data file is another question for another day, :).

    Okay it asks me for an expression when I go to add trace. What expresssion do I put in the box? I am trying to find calculated Vo magnitude and phase angles of a 2 pole low pass filter; filter 1 has 2.2 K R and 470 nf; #2 has 22 K R and 47 nf. I have a range of 9 Hz to 9 KHz of fc, decade sweep with 1 point per decade.

    The Vo is over the 47 nf cap in the 2nd pole filter.
