Simulating Target Response

[Dean Sarelius]

Use the SPICE command .step to vary the resistance, use a very high value for no target, like 100 MOhm. It will run a simulation for every value of R in the list.

Hi Teleno,
I downloaded a Pspice simulation not sure who it was maybe moodz and have been studying the attached simulation polar2b but can not see where the coupling co-eficient K has been specified for the targets..?
I can see K1 , K2 etc but they dotn appear to be spice controls just text as far as I can tell..?
Its ok if you are unable to help with this question as I have several other simulators I can try this circuit with like Multism, Circuitmaker and Proteus.
