2Hz ? I thought it they were a pulse on the even second, thus actually
0.5 Hz ?
I wonder how the PPS Driver in NTP would react to that (either 2Hz, or
0.5Hz pulses). I guess if it really is 2Hz, then one of Tom's PICs
could be used to drop it to 1 Hz
But if it's 0.5 Hz, I wonder if a modification to the ATOM driver
or underlying PPS code would be needed
Or is the 2Hz signal coming off the SCPI port ?
Iain (and yes, like others, I am interested)
