If you send out the pulse and nothing comes back, the device you sent it to is terminated correctly at the far end, so there is no reflection. If it isn't terminated correctly you will see a return pulse, upright or inverted, and if the device isn't correctly terminated at the sending end you will see successive reflections, decreasing in amplitude due to the losses in the device. It's a rather attractive technique. -- OOO - Own Opinions Only. With best wishes. See www.jmwa.demon.co.uk Quid faciamus nisi sit?
