HP 70427A Microwave Downconverter
downconverter's input attenuator is set to zero and the signal goes directly to
the IF amplifier.
The μW LO output is connected to the external mixer's LO input. The
external mixer generates harmonics internally. One of these harmonics
mixes with the input signal to produce an IF between 5 MHz and 1.2 GHz.
The HP 70427A includes the functions of the HP 70428A Microwave
Source. When the module is used as a downconverter, the source hardware
functions as the internal local oscillator (LO). When the
