开云体育I have a 5300A measuring system readout with a
5302A 50 Mhz counter.? When I first turn the unit on, with the function
knob dialed to "check" the counter reads 10.0000 Mhz but after it warms up for a
few minutes, the counter begins to read 9.9999999 MHz.? If I plug a cable
from the front bnc to the timebase output it reads 10.0000 Mhz.? I have
adjusted the crystal frequency to give correct readings from a more accurate 10
Mhz reference.? Is the check function supposed to read 9.999999 or is it
supposed to read 10.0000000?? I don't have a manual, so I don't
know.
?
Thanks,
