The CL-SIP365, Microwave Communications Trainer, includes a basic microwave link which consists of transmitter panel, receiver panel, plus microwave components for transmission line studies. For experiments 16-18, two additional panels are required, one from the Optoelectronics Trainer (CL-SIP375-3P) and one from the Digital Communications Trainer (CL-SIP397-3P). One S300PB Panel Base will also be necessary for these experiments. The CL-SIP365 comprises a transmitter that radiates a modulated signal on either 3.5 or 4 MHz.

The radiated signal can be modulated by 5 kHz tone, 750 and 1800 Hz audio tones. The transmitter can also be voice modulated from a panel-mounted microphone. All tone oscillators are controlled by crystal-controlled synthesized circuitry. Filters are provided to eliminate either upper or lower sidebands. A spectrum analyzer is built into the panel and enables the user to observe the carrier with upper and lower side bands. Switches and controls are provided for suppressing the carrier and filtering out either the upper or lower side band. The panel can be used in conjunction with the single-sideband receiver (CL-SIP329BC). The course provides for approximately 69 hours of instruction.
