Agilent Technologies L4445A manual

Microwave switch driver for easy routing of high frequency signals in your system

The L4445A allows you to control switches, attenuators and other devices close to your device under test. The L4445A combined with the 34945EXT provides the power and control signals to drive up to 64 switch coils—that’s 32 standard SPDT switches.

The L4445A can be extended by adding additional 34945EXT extenders. The first 34945EXT is powered by the L4445A. You can add up to seven additional 34945EXT extenders with user supplied power. Multiple switch operations are performed in sequential order, or for faster, simultaneous switching, you can connect an external power supply to the 34945EXT.

The digital outputs can also be used to drive LEDs for indi- cation of the switch position. The L4445A/34945EXT also has digital inputs so that you can read back the actual position of the switch or attenuator.

The L4445A comes with a standard 9-pin connector for simple connection to the 34945EXT. The Y1150A-Y1155A distribution boards plug onto the 34945EXT and are used to route the power and control signals from the driver to the switches using user supplied cables. This enables simple connections to the external switches without a lot of complicated wiring.

The following microwave switches and attenuators are supported with the Y1150A- Y1155A distribution boards:

•N181x/U9397x series SPDT switches

•8762/3/4 series SPDT switches (screw terminals)

•8765x coaxial switches

•8766x/8767x/8768x multiport switches

•87104x/106x/L710xx/L720xx multiport switches

•87406x series matrix switches

•87204x/206x series multiport switches

•87606x series matrix switches

•87222x/L7222 transfer switches

•849x series attenuators

•8490x series attenuators

•Screw terminal connections

Ethernet connectivity enables simple connection to the network and remote access to measurements

The Ethernet interface offers high-speed connections that allow for remote access and control. You can set up a private network to filter out unwanted LAN traffic and speed up the I/O throughput, or take advan- tage of the remote capabilities and distribute your tests world- wide. Monitor, troubleshoot, or debug your application remotely. Ethernet communication also can be used with the support of LAN sockets connections.
