Headend/Hubsite RF multi-carrier CW test signal generator.
The Model 1685 is a headend/hubsite RF multi-carrier generator. It is custom-built and can be built in configurations from 1 carrier up to 8 carriers with any carrier frequencies from 5 MHz up to 1200 MHz. Each CW carrier can be activated individually or simultaneously. The RF carriers generated are extremely clean and stable, thus making the 1685 an ideal instrument for testing/aligning the CATV forward band.
