Pickering: Relay Self Test for PXI Switching
Multi-slot matrix modules.
Clacton-on-Sea, UK — Verification and diagnosis of complex switching operation in a test system has always been an issue, especially in the PXI platform. For this reason, Pickering Interfaces is introducing built-in self test to certain models of its PXI switching modules. This feature is called BIRST, or Built In Relay Self Test.

The first range of modules with built in self test have been released and include: 40-560A BRIC 150V, 0.5Amp, 1 Pole Matrix Relay Family; 50-561A BRIC 150V, 0.5Amp, 1 Pole, 1 Pole Screened, or 2 Pole Relay Matrix Family; 40-562A BRIC 150V, 1Amp, 1 Pole, 1 Pole Screened, or 2 Pole Relay Matrix Family; 40-563A BRIC 40V, 0.25Amp, 1 Pole Solid State Matrix Family; 40-584 128 X 2, 300V, 2Amp, 1-Pole VHD Matrix Module; 40-585 64 X 4, 300V, 2Amp, 1-Pole VHD Matrix Module; 40-586 32 X 8, 300V, 2Amp, 1-Pole VHD Matrix Module; 40-587 16 X 16, 300V, 2Amp, 1-Pole VHD Matrix Module; 40-527 64 X 2, 300V, 2Amp, 1-Pole HD Matrix Module; 40-528 32 X 4, 300V, 2Amp, 1-Pole HD Matrix Module; 40-529 16 x 8, 300V, 2Amp, 1-Pole HD Matrix Module.

The BIRST tool allows the user to easily check system switching operation on command. BIRST will identify any relay failures in the switch module and is capable of detecting relays with deteriorating contacts which may indicate they are in the process of failing. To conduct a test, the user simply disconnects the switching module from the UUT and runs the supplied application program. No supporting test equipment is needed; the test simply runs and identifies the position of any defective or suspect relays within the module.

Over time, the BIRST solution will also be applied to other PXI modules as well as the company's LXI product family, which include a range of very large matrices.

The company is also introducing a new range of scalable RF matrix switching solutions with LXI-compliant Ethernet control. The new solutions use an innovative construction that allows the company to create almost cable-free RF matrices in 50Ω and 75Ω with frequency coverage up to 3GHz. The first product introductions are 32 X 16 and 32 X 8, but the construction methods used allow the creation of a wide range of other matrix sizes.
