The HP 71708A microwave source makes an excellent substitute LO
for your radar system, phase noise measurement system, or test source
for microwave receiver testing. It provides the lowest AM phase noise
of any commercially available microwave source and provides up to +16
dBm of output power. The standard HP 71708A has a frequency resolution
of 600 MHz. If finer frequency resolution is required, Option 002 and
an HP 8662A synthesized signal generator can be added to provide
resolution of 0.1 Hz. Components of the HP 71708A include the HP 70428A
microwave source module and the HP 70004A color display/mainframe.
