We have two sources and we want to be able to measure their
frequencies at the same time. We want to get a time record
of frequency each second. Apparently, what is meant
by a "two channel" frequency counter is that you get the
frequency of either channel A or channel B but not both
at once. Some can also measure the ratio of A to B, but
that doesn't work for us.
We seem to be left with using a separate counter for each
source and doing data logging with time stamping. We can then
reconstruct the two frequency records after the fact in a spread sheet.
There is the problem of synchronizing the time stamping
clocks in the two counters.
Can anyone on the list point me to a true two channel
counter that would just measure the two sources? We are
working around 200 MHz, but could possibly prescale.
Thanks
