I managed to take a photo at the scope screen showing the 1 pps pulse from an old FE-5680A (the one that does not need the 5V and does not output the oscillator signal - just the 1pps).
Exposure was 30 sec, F9. The signal was barely visible with naked eye, and some jittering is present. The room of course was in complete darkness, but the reflex of the stand-by led of another instrument can be seen... 73 Alberto I2PHD http://dl.dropbox.com/u/15089947/1pps.gif _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
