I need an accurate, (preferably xtal controlled), device to give me a pulse
marking each hour, to time stamp my 3 seismographs 24/7
I need one pulse at 1am and two pulses at 2am,
10 pulses at 10am and so on.
It can be either 12 or 24 hour markers
(1 to12 or 1 to24 pulse outputs)
The pulses can be at the any voltage or even a relay on/off/on/off..... to give
the hour number.
Does anyone know such a device on the market, please?
I have searched the net but cannot find anything.
At present, about 3 times a day, I listen to pips on the radio
and bang my foot on the ground (!) the number of hours to give
pulse markers on seismograph trace recordings.
It works OK but isn't very scientific :-)
