DESCRIPTION
1-20.
The 5355A plug-in unit, when used with a 5345A Electronic Counter provides measure¬
ments of CW or burst frequencies from 400 MHz to 1.6 GHz. Since the 5345A has a range of Oto
500 MHz, the 5345A/5355A combination offers frequency measurement capability from 0—1.6
GHz. Frequencies up to 40 GHz may be measured by use of the accessories described in the
following paragraph.
1-21.
For higher frequency measurements, the 5356A, 5356B, or 5356C Frequency Converter
Head is used. The heads use the single sampler, harmonic heterodyne technique to downconvert
the Input signal frequency. The 5356A allows measurements from 1.5 to 18 GHz,the5356B allows
measurements from 1.5 to 26.5 GHz, and the 5356C allows measurements from 1.5 to40 GHz. The
head connects to the signal source and the attached 5V2 foot cable connects to the multipin
connector on the front panel of the 5355A.
1-22.
Signals in the 0.4 to 1.6 GHz range are sent through a prescaier (divider) in the5355A to the
IF circuits. Signals in the 1.5 to 40 GHz range are sent through the down-converter head to the IF
circuits. The 5355A automatically acquires the input CW or pulsed rf signal and under control of
its microprocessors algorithm, routes the down-converted signal to the 5345A mainframe to be
counted and displayed.

SERVICE EQUIPMENT AVAILABLE
1-24.
A kit of extender boards is available to allow servicing printed circuit assemblies while
extended from the instrument. The extender boards allow the assemblies to be extended from
their pi ug-in connectors for monitoring with appropriate test equipment. The HP part number of
the kit is 05355-60100. Refer to paragraph 8-183 for detailed information.

RECOMMENDED TEST EQUIPMENT
1-26.
The test equipment listed in Table 1-3 is recommended for use during performance tests,
adjustments, and troubleshooting. Substitute test equipment may be used if it meets the required
)
characteristics listed In the table.
