Re: 577D1 Phantom base current

Here is a idea

If someone with a 577 curve tracer try this test, install a transitor and with the step generator set to single and increase the collector voltage does the display indicate some current. Does moving the step generator amplitude proportionally effect the amount of current displayed?

I am thinking if someone could duplicate this with a good known 577 we will see if this is by design or if it is a fault.

Thanks
