The PFM3000 offers high sensitivity frequency measurement from 3Hz to more than 3GHz in two overlapping ranges.
Period measurement is also provided from 8ns to 330ms.
The PFM3000 uses a continuous reciprocal measurement technique to provide high resolution at all frequencies with rapid update.
It offers high sensitivity across the whole frequency range.
A low pass filter can be selected to reduce high frequency signal noise at lower frequencies.
