Description Frequency Converter
                                    The Hewlett-Packard Model 5254C Frequency Converter is a
plug-in unit which extends the frequency measuring
capability of an HP Electronic Counter from . 15 to 3. 0 GHz
(150 MHz to 3000 MHz).

The stability and accuracy of the basic counter are retained
by multiplying a 10-MHz signal, derived from the 1-MHz
internal tizne base of the counter, to 50 MHz and selecting
a harmonic frequency between 200 and 2950 MHz. This known
harmonic of 50 MHz is then heterodyned with the INPUT
signal. The resulting difference frequency, if between 1 MHz
and 53 MHz (bandwidth of amplifier in plug-in) is counted
and displayed by the counter. The frequency of the INPUT
signal is then indicated by the combination of the MIXING
FREQUENCY control (in gigahertz; front panel of plug-in) and
the digital display of the counter (in megahertz).
