New switching modules

Pickering Interfaces, a leading provider of modular signal switching and instrumentation for use in electronic test and simulation, has launched four new switching modules. These products include a new PXI signal insertion and monitor matrix, and updates to their PXI microwave multiplexers, PXI high-density large matrix BRIC range and PXI fault insertion switches.

“Test engineers continue to request more choice, higher density and additional features in switching,” noted Keith Moore, managing director at Pickering Interfaces. “We consistently invest heavily in R&D to provide the right amount of switching to meet our customers needs – we have introduced over 20 new and updated LXI, PCI and PXI switching products in the last year alone.”

The new PXI Signal Insertion and Monitor Matrix (40-525A) – a 34x4 matrix with both switched and direct connection paths to the X and Y-axis. This matrix permits test signals to pass thru the switched X-axis to the unit under test (UUT) on the direct X connection, the switch allowing each thru path to be opened to disconnect the stimulus signal. The direct Y-axis to the matrix allows the user to monitor the signals with test equipment, such as an oscilloscope or DMM, the matrix allowing the test equipment to connect to any of the 34 thru connections.

The 40-525A signal insertion and monitor matrix uses electro-mechanical relays that are capable of switching currents up to 2A and voltages of up to 300VDC or 250VAC. User connections are provided on an easy to use 78-way D-type connector which is fully supported by Pickering Interfaces' range of connector accessories.

The PXI Large Matrix BRIC Update (40-565B) – now with 20% density improvement over previous models, these high-density large matrix modules are able to switch up to 2 Amps at 200VDC/140VAC. These PXI matrix BRIC modules are available in 2, 4, or 8-slot PXI sizes for most high performance PXI matrix requirements. With this high level of switching density, these BRIC matrix modules allow a complete functional ATE system to be housed in a single 3U PXI chassis.
