Pickering Interfaces, a leading provider of modular signal switching and instrumentation for use in electronic test and simulation, is expanding its range of PCI and PXI Programmable Resistors.

Expansion of existing range

The existing PCI High-Density Precision Resistor Card (model 50-297) and PXI High-Density Precision Resistor Module (model 40-297) have been expanded to increase the versions offered from 6 to 42; each version offers users the choice of the number of resistor channels, resistance range and the resistance setting resolution. Depending on the version the resolution is from 0.125? to 2? and resistor channel counts from 3 to 18. Resistor values up to 1.51M? can be simulated.

New product introduction

Pickering is introducing the new PCI Programmable Resistor & Relay Card (model 50-293) and the new PXI Programmable Resistor & Relay Module (model 40-293) offer lower densities and cost solutions (compared to similar products) for simulating resistors with 12 versions available having resolution from 0.25? to 2? and channel resistor channel counts of either 2 or 4. In addition, each of the 12 versions has the option of adding 8 SPDT relays which can be used for other switching functions within a test systems their use potentially saves the addition of further switching products within a test system.

All of these PCI and PXI resistors are programmed by the use of resistance calls from the driver, the driver uses calibration data from the module to give the best setting available to the user and can also return to the user the theoretical value of the resistor. Basic accuracy is 0.2% ± resolution for the 40-297 and 50-297 and 1%± resolution for the 40-293 and 50-293.

By offering the programmable resistors in different form/factors with the same options Pickering Interfaces continues to promote its test solutions in multiple platforms, allowing the user to choose the most appropriate platform for their test system.

Pickering Interfaces supports all of their manufactured products with a standard three-year warranty and guaranteed long-term product support. Pricing and availability information is supplied on their web site www.pickeringtest.com.
