| Today's most
accurate frequency counter
With a built-in Rubidium
atomic resonance-controlled frequency reference, the PM
6685R is the most accurate frequency counter on the
market and it has the additional benefit of full
portability.
High stability, high
accuracy and short warm-up time make this instrument
ideal for high-accuracy calibration procedures outside
the calibration laboratory environment, such as in base
station transmitters of large telecommunications
networks like GSM.
The short warm-up time
makes that the PM 6685R is ready for use quickly, for
example after transport or change of location inside a
building.
