PSPICE changing the Phase Angle

Fri May 27, 2005 11:13 pm   

What's the best way to change the phase angle of an ac sign wave? For
example, I'm trying to sim costas loop, and I need a 90 degrees phase
shift from the VCO output.

I'm sorry, but I'm lost. I'm new to pspice... how would you implement
this?
I'm creating somthing like a costas loop, and I need a variable VCO
with 0 and 90 degrees phase shift at a variable freq.
