<p>
<P>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.</P>
<P>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. Despite its compact
dimensions, the PFM3000 incorporates a large 8 digit LCD. Annunciators are
provided for measurement function, measurement time, overflow, trigger activity,
low battery, and measurement units.</P>
<P>Despite its wide frequency range the PFM3000 has a power consumption that
enables it to operate for many hours from a PP3 size battery. A push-to-measure
capability gives an instantaneous reading followed by an automatic power down
after 15 seconds. This provides greatly extended battery life where continuous
monitoring of the signal is not required.</P>
<P>Bench-top use The PFM3000 has the performance needed for many bench-top
applications, and its built-in tilt stand sets the display at a convenient
angle.</P></p>
