Operation
System Description
Since the HP 85105 mm-wave controller includes RF and IF switching
hardware, the system may also be configured for coaxial measurements from
45 M Hz to 50 GHz. This is achieved by the addition of a coaxial test set that
has convenient switching between coaxial and waveguide test sets. If the
optional microwave test set is installed in the system, the RF signal, 20 MHz
IF signals, and phaselock control signals pass through the test set controller
before entering the HP 8510C IF/detector section. You can add two
additional coaxial test sets to the system by adding external RF and IF
switching hardware. This is described in Chapter 6, "HP 85105A mm-Wave
Controller".
