  • Page 5: Introduction

    PREFACE Introduction The SignalOn Series RF Switch Module is designed to be installed in the 8- or 20-position SignalOn Series chassis. Each RF switch module occupies two positions in the chassis. The mechanical dimensions, cable management, and aesthetics of the RF Switch Module are compatible with the SignalOn product line. The system is designed to accommodate superior cable management and ease of use.

  • Page 9: Product Description

    CHAPTER 2: PRODUCT DESCRIPTION PRODUCT DESCRIPTION Product Description Primary function of the module is to monitor the RF signal gain on the operating primary “A” input, and switch to the backup “B” input if the gain of the primary path rises, or falls below the calibrated RF input level of the unit. If the “A” input side goes above, or falls below the threshold of the unit, the RFSM quickly switches the input from the failed input to the secondary input.

  • Page 11: Applications

    CHAPTER 3: APPLICATIONS APPLICATIONS Applications Typical applications of this switch are to protect two optical to RF receivers, or redundant amplifiers. In this setup, the RFSM can independently protect one or two pairs of receivers, or amplifiers. Once the RFSM detects a signal level rising above, or falling below the preset threshold level, it switches from A to B or B to A for that RFSM.

  • Page 19: Input Rf Level Calibration

    CHAPTER 6: SYSTEM OPERATION 6.1. Input RF Level Calibration Calibration is performed using the SET button. The RFSM compares each RF input level to a user-selected ±3 dB or ±6 dB switching threshold, and to minimum/maximum input limits. To pass calibration, when B-Relative-To-A Mode is selected, the power level of B must be within the threshold window of A.
