The ITS-9020 Transmission-Reflection Test
Set is a flexible, modular instrumentation system designed to measure
transmission loss and reflectivity of materials at various frequencies in both waveguide and free-space environments.
The Test Set consists of three modules that are combined to
create a complete measurement system. Transmitter modules (Model ITS-9021) consist
of a phase-locked dielectric resonator oscillator (PLDRO) followed by an active
frequency multiplier to generate MMW frequencies in popular waveguide bands from 26 GHz to 110 GHz. The RF output goes to a variable,
manual attenuator, and then connects to a transmit antenna.
Receiver modules (Model ITS-9022) have a similar PLDRO and
multiplier combination that form a local oscillator that drives a balanced
mixer. Received signals are downconverted to a fixed IF and then
amplified and filtered. The IF output
from the Receiver module connects to the common ITS-9020 Processing module for
The ITS-9020 Processor provides IF amplification, filtering,
gain control, and log detection. In addition, it also supplies DC power for the
remote transmitter and receiver modules as well as a 100 MHz reference for the
PLDROs. An internal processor provides Ethernet connectivity and control of the
various programmable parameters for the system. An integrated LCD and keypad
provides a local power and status display as well as allows system parameters to
be set manually.
