JFW Industries model 50AA-097 LC Handover Test System with Manually Variable Attenuators

Manual handover test system for handover testingManual Handover Systems

JFW’s manual handover test systems provide a simple solution for RF testing wireless devices by combining our manual rotary attenuators and RF power divider/combiners into a convenient benchtop enclosure.  All of the internal RF components are passive so no power supply is needed to operate the test systems.  Simply turn the knobs to adjust each attenuator setting.  Adjust a single manual attenuator to perform a signal fade test.  Use two manual attenuators simultaneously to perform a manual handover test.

Manual 4 x 1 LC Handover System

The below block diagram is an example of a manual 4 x 1 LC handover test system. Four different communication standards (i.e. Wi-Fi, WiMAX, LTE) can be connected to the four input ports. Each communication standard can be attenuated to different levels. The output port containing all four communication standards is then connected to the handheld device.

Manual 3 x 4 LC Handover System

The below block diagram is an example of a manual 3 x 4 LC handover test system. Three different communication standards (i.e. Wi-Fi, WiMAX, LTE) can be connected to the input ports. Each communication standard can be attenuated to different levels. The three communication types are combined together and then split into four signals. This configuration allows testing of four handheld devices at the same time.
