Handover Test Systems

Family of handover test systems designed for cellular handover testing. Internal step attenuators allow the RF signal between the network access points and the handsets to be dynamically faded up/down.  The Ethernet/Serial models run our latest generation 3.x.x firmware that features easy to use ASCII formatted commands.

Full Fan-out Handover Test Systems
This type of fan-out provides connections for multiple handsets and multiple network access points.  The RF signal between each handset and each access point can be faded up/down.  The full fan-out handover test system is constructed with power divider/combiners on both halves of the matrix with a step attenuator on every path through the matrix.  Every RF path through the matrix can have its own unique attenuation setting.

4X4 Full Fan-out Handover System:  16 step attenuator, 16 RF through paths
8X8 Full Fan-out Handover System:  64 step attenuators, 64 RF through paths

Limited Fan-out Handover Test Systems
A 4X1 limited fan-out has connections for a single handset and four network access points.  The internal step attenuators can fade the RF signal from each access point to the handset.  The limited fan-out handover test systems are constructed with a step attenuator on each input port with a power divider/combiner to combine all signals onto a common path.  This design limits the number of step attenuators to be equal to the number of input ports.

4X1 Limited Fan-out Handover System:  4 step attenuator, 1 RF through path
8X1 Limited Fan-out Handover System:  8 step attenuators, 1 RF through path

Manual Handover Test Systems
Full fan-out or limited fan-out configurations but with manual step attenuators. These models require no AC power.
