Product Overview
ZT-24RFX8 is a “full fan-out” or “fully non-blocking” matrix. These systems use a combination of
programmable attenuators and splitter / combiners to provide a completelyflexible set of paths between the
input and output ports. The configuration is analogous to a switch matrix except any individual path can be
“on” (0 dB attenuation), or “off” (max attenuation), or any specific path loss in-between. In addition, all
inputs can connect simultaneously to all outputs,and all paths are bi-directional.
This completely flexible set of path characteristics is ideal for cellular transceiver and handover test
requirements, particularly complex LTE eNodeB applications. Multiple signal sources and interferers can
be combined into any combinationof DUT at precisely tailored signal levels.
The matrix is housed in a 5U height, 19-inch rack chassis with SMA RF connectors on the front and rear
panels. The system can be controlled via USB or Ethernet (supporting SSH, HTTP & Telnet network
protocols). Full software support is provided, including our user-friendly GUI applicationfor Windows and a
full API with programming instructions for Windows and Linux environments (both 32-bit and 64-bit
systems).
