I have an EIP Model 548 counter with a YIG-tuned front end that can be
programmed to scan over narrow frequency ranges. By feeding the rubidium
oscillator under test into the 10 MHz clock input of the counter, is there any
reasonably simple way to directly measure the frequency of a GPS satellite
transmission so as to ascertain the accuracy of the rubidium source? The
counter has
an input sensitivity in the order of about –25 dBm -- not sufficient to
measure directly from an amplified antenna, but perhaps through an amplifier.
I
am not sure whether the input YIG tuner selectivity is sufficient to separate
transmissions from the various satellite’s (or are they TDMS?). What do you
think?
