When you say emulate, are you trying to simulate it on a spice model, or do a real test with a simulated line? If the latter you are probably best to get a reel of cable from the local radio Shark or similar store, and find the inner end, and connect both ends to your circuit. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
