OrCAD Pspice Users: How do I....?

[jmcoreymv]

I drew out a simple circuit in orcad. What I want to do is have some switch that either opens or closes at t=0, and then have pspice show me the transient response to whatever variable im measuring. Anyone know how to do this?

what are you trying to do exactly?

what type of circuit is it?

 

[jmcoreymv]

Its a basic RLC circuit with a few resistors placed here and there and a voltage source. I have a switch that I want to close at t=0 (which basically disconnects a resistor), and I want to measure the current source through the inductor. I have everything setup except the switch.

use a voltage source with a square wave of really long period, it'll have the same effect.

That wont allow me to disconnect one of the resistors at t=0.

do you have Pspice Schematics by any chance?

 

[jmcoreymv]

I believe so. v9.1

 

[brunswickite]

schematics has a switch, component that you can play with

 

[jmcoreymv]

I guess maybe I dont have pspice schematics, I have Capture, and the Pspice simulator.

In the EVAL library there's 'Sw_tClose' and 'Sw_tOpen'. These are switches, the TCLOSE and TOPEN values are the time in seconds when the switch changes state.

I just did a quick search for an eval library and nothing turned up. Do you think you could email it possibly?

 

[Yomicron]

you've got mail

Awesome, thanks. I used the closing switch and it worked great.
