[time-nuts] FE-5680A 1 pps photo

[Alberto di Bene]

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...
