[time-nuts] Why are 1PPS signals so skinny?

[SAIDJACK at aol.com]

Hi Rick,
 
one reason why we "happy blink" at 1/2Hz :)
 
There are other offendors as well, such as the processor and GPS going  
through the hoops once per second, but the 100mA surge from the 1PPS output  
driver trumps all else.
 
bye,
Said

FWIW, the  E1938A oscillator control board had a "happy light" LED
that flashed 1 time  per second, and sure enough this corrupted the
power supply and affected  some applications.  We added a command
to turn it off.
