Electron Reversing Device

Poynt:

I am unsure about the output impedance of the square wave generator.  I was under the impression that it was new hardware, a "transformer output."  The current is up to 100 mA, so perhaps Tinman can clarify that.

I will drop in a resistor and play with it.  It would be fun illustrating how a high output impedance in the square wave generator "sucks the life" out of the circuit.

I didn't set up a simulation profile so I will look into that.  Nothing happens right now, no sim sceen.  In the back of my mind I was hoping that the software would set up some default sim parameters.  That will be easy to set up myself.  I also assume it will be trivial to copy the conventional schematic into a simulation schematic if that's the case.

I seem to recall a story about development on the student version being abandoned.  The program install and GUI feels like it is about 10-12 years old.  Not sure if it is multi-threaded/multi-processor aware, but it's not that important.  I upgraded my solid-state drive recently and the program runs like lightning.  It's a complex program but definitely feels like it was written for scientists and engineers.  Although complex with lots of files to manage, it isn't in a stupor because of bloatware.

Gee wiz,
A Rookie mistake MH    

Although I guarantee your first effort posted above looks like a picasso
compared to mine...............

Poynt:

I got a basic simulation running by starting the Orcad Capture program in Administrator mode in Windows 7.  You have to right-click on the program shortcut to do that.

I got a simple RC circuit to run and saw the plot.

Now my problem is that if I add a diode, then the simulation fails because it can't find the model for the diode.  I just added "d" to the schematic, a basic diode.  So I hope to figure that out soon.

ERROR [NET0085]   Part D2 has no 'MODEL' property

I tried starting the simulation program in Administrator mode ahead of time but that didn't work.  I also tried adding the available libraries in the pspice directory to the simulation program but that didn't work.

MH,

In the student version pspice (nom.lib) library, is there no diode with a part number?

You will be looking for "D1NXXXX".

MH,

I see also that you are running your FG at 10MHz. You sure you want it that high?

Also, I think the FG output is +/- 6V.

It also appears that you have two FG's overlayed on each other. You need to delete one.
