Reply to "Design of a $10-20 DCS-TIU Port Tester Tool?"

Regarding the AC-power version. I realize this measures the DCS amplitude with no load on the TIU output except the tester itself (or an oscilloscope). That said, since the tester is such a minimal load, is there any chance it can be powered by the TIU output itself?

That would make for a simple 2-wire connection. I'm imagining the temptation will be great to see how the LEDs blink at various points on a large layout (no trains, just the track). Not clear where you'd get the AC power in such a situation. But then, ironically, the tester would need a 22uH choke!
