electronica_2010Pickering Interfaces shows BIRST on LXI devices

26 October 2010 - Pickering Interfaces has continued in 2010 to regularly release a steady flow of new products in both the LXI and the PXI platforms. Amongst a variety of products, also the European Launch of BIRST (Built-In Relay Self Test) on LXI devices will be shown at electronica 2010 on Booth A1.530.

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 has developed a range of PXI modules with built in self-test This feature is called BIRST, or Built In Relay Self Test. The first PXI modules with built in self test have been released a year ago and new launches continue to include BIRST in PXI matrix modules. At electronica 2010 BIRST on LXI Devices will be shown for the first time in Europe – and demonstrated on a 60-555 LXI matrix.

In addition all Pickering Interfaces products are now fully LXI compliant to the latest 1.3 specification, significantly increasing the number of LXI products available with the most recent additions to the standard. Pickering Interfaces is committed to following the LXI standard’s evolution and adopting its newest features to improve user experience of Ethernet controlled instrumentation.

New PXI products on display:

• 41-743 Single Channel Power Supply

The 41-743 is a single channel power supply capable of providing 2A at output voltages up to 20V and 0.8A up to 48V. The powers supply includes remote sense connections to allow load sensing at the end of cables. A voltage monitor and programmable current limit is included and the module supports PXI Triggering as well as external triggering. Backplane power is derived from the two slots the module occupies to allow the 41-743 to generate the full output capability without the use of an external power source.

• 40-737 High Channel USB Multiplexer

The 40-737 is an 8 to 1 multiplexer for switching datacomms signals and has been specifically designed for routing USB. The data signal paths are 2-pole arranged as differential pairs as defined by the USB standard. The signal pair have a controlled 100 ohm differential impedance and the multiplexer has been designed for minimum insertion loss. The power paths are designed to ensure minimum loss of the USB power.

• 40-755 50 Ohm RF Multiplexer with 10 off SP4T switches to 1.8 GHz

The 40-755 is a high density low cost solution for RF switching which is available in 2 mechanical formats. The 2 slot version supports RF switching to 1.8 GHz, the single slot version uses a multipole connector suitable for use to 500 MHz (a connector limited bandwidth.

• 40-582 2-Pole 16x16 Matrix Module

16x16 2-pole matrix module with BIRST self test in a single PXI slot

• 40-331 and 40-332 High Voltage (1000 Volts) Matrix & Multiplexer modules

• 41-752, a recently introduced Battery Simulator, which is being used by automotive customers to test battery management systems for electric vehicles.

Developed in association with DMC, a systems integrator based in Chicago, the 41-752 is a 6 cell battery simulator that provides up to 300mA of current from each cell. The output voltage from each cell is fully adjustable up to 7V and each cell includes its own sense lines to improve regulation performance. Each cell can be configured to operate as a current sink in a battery charging circuit of up to 100mA. Cells and modules can be series connected to emulate the battery stacks being used in new generation electric vehicles. More than 100 cells can be stacked in series in a single Pickering Interfaces PXI or Modular LXI Chassis to allow the testing of battery management charging systems. The independently controlled channels allow the cells to be set to different output voltages to simulate different charge and capacity states. A safety interlock system can be used to ensure that voltage generation is inhibited when the cables are disconnected from the front panel. Outputs are made available on high voltage D Type connectors permitting the generation of voltages of up to 750V.
