Original poster: "Michael H Nolley by way of Terry Fritz <twftesla-at-qwest-dot-net>" <nolleym-at-willamette.edu> If the TSG were to be used on a DC coil, the timing issue would be non-existent, am I correct? If so, how configurable could you make the TSG bps? It would be cool if you could adjust the breaks between 1 and several hundred bps. --Mike
