R&S®TS-PIO3B Digital I/O Module and Coil Driver

The R&S^®TS-PIO3B is a versatile digital I/O module with 64 channels that can be operated on all CAN bus slots both in the R&S^®CompactTSVP and in the R&S^®PowerTSVP.

The R&S^®TS-PIO3B offers eight ports with eight digital I/O lines each that have MOSFET output drivers. The circuitry is designed to drive RF relays with all common control voltages. The high current-carrying capacity makes the module a universal coil driver.

Owing to its layout as a "short" card in the European format, the module can be integrated into the front area of the R&S^®CompactTSVP. To allow standardized distribution of digital control ports, the R&S^®TS-PTRF signal port and transmission module is available. Directly off-the-shelf RF relays or up to eight R&S^®TS-PXM1 switching extension modules can be connected to this module. Arriving from the front, DUT signals can also be fed through to the R&S^®TS-PIO3B module either directly or via a test fixture.

The R&S^®TS-PIO3B module is supplied with an IVI-Ccompliant LabWindows/CVI driver, which offers function panels and online help as a common feature. Alternatively, all switching functions can be called via the generic test software library (GTSL) switch manager.

The R&S^®TS-PIO3B features are completely described in the GTSL software framework and are delivered to the user as a DLL file to support their use in various programming environments.

The built-in selftest capability of the module provides fast diagnostics to verify base interface functionalities. The scanning tool derives the VISA address by a mouseclick and enables the user to verify proper interface operation at a glance.

• Eight quasi-bidirectional digital I/O ports with 8 bits each, i.e. 64 digital I/O signals are available
• Cost-effi cient digital I/O module with large number of channels
• Outputs with MOSFET driver transistors in open drain
