PXI And IVI Compliance Switching ModulesSource: Dow-Key Microwave Corp.
The RF switching modules are design for complex test setups and sophisticated switching requirements.
The module is configured as a non-blocking crossbar with 4 inputs and 4 outputs. The coaxial switch operates between DC to 18 GHz and the module occupies 4 slots of a 3U PXI chassis. The switch is equipped with (5) external semi-rigid cables that are arranged such that a 4x4 matrix configuration is created. By removing some or all cables, it allows the user to reconfigure the module to sets of standard coaxial switches e.g. SPDT, DPDT (Transfer), SP4T etc. Further by adding external 50 W loads one can configure the matrix to a terminated switch. Note that the provided software package supports any reconfiguration that is possible within the 4x4 matrix.
Datasheet: 14F3S-1/4x4 PXI RF Switching Module
The switching module is configured as a non-blocking crossbar with 2 inputs and 5 outputs. The coaxial switch operates between DC to 18 GHz and the module occupies 4 slots of a 3U PXI chassis.
Datasheet: 14F3S-1/2x5 PXI RF Switching Module
This switching module can be populated with maximum (3) miniature coaxial switches and with any SP3T, SP6T, Dual SPDT (two SPDT in one switch), and DPDT (Transfer) switch. Thus, it can be reconfigured as one desires. The operating frequency for each switch is from DC to 26.5 GHz and the module occupies 2 slots of a 3U PXI chassis.

Software Control (Applies to all modules):
Graphical User Interfaces (GUIs) are provided in LabVIEW, LabWindows/CVI, and Visual Basics to allow the user to control the switch easily. For advanced programming, VISA and IVI drivers are included such that one can program and control the switch in any way desired using e.g. LabWindows/CVI (NI developed ANSI C-based programming), LabVIEW, Visual Basics, C or any other desired programming language or platform.
