Fellow time-nuts,
To support the kind of burst measurements I am playing around with it
would be good to be able to generate bursts of transitions rather than
even clocks. Depending on the counter it may be simple (say using a
HP5372A) or a little more difficult (DTS 2070C).
Creating a burst of 10 kHz transitions for 10 or 100 ms should be
possible to do in the PIC code with some hacking.
Similarly creating a burst of 5 or 10 MHz clocks for 1 ms should not
be too hard by sniffing the clock after the input shaper and the
enable pulse from the PIC.
I thought I would bounce this and see if people have any ideas other
than mine... anyone else interest...
Cheers,
Magnus
Since an external gate is required to implement the 5/10MHz clock burst
it would be simpler to have a selectable pulse width for say the PPS
output and use this to gate either the 5MHz/10MHz or 10kHz as required.
