Pickering Interfaces has released additional programmable resistors under its PCI and PXI series, which expand the selection of number of resistor channels, resistance range, and the resistance setting solution.

The product expansion features a resolution ranging from 0.125? to 2? and resistor channel counts from 3 to 18. Resistor values up to 1.51M? can be simulated.

The company has also unveiled its PCI Programmable Resistor & Relay Card and a PXI Programmable Resistor & Relay Module, which offer lower densities for simulating resistors with 12 versions, having resolution ranging 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 test systems.

All of the PCI and PXI resistors are programmed by the use of resistance calls from the driver. This driver uses calibration data from the module to give the best setting available to the user, as well as return the theoretical value of the resistor. The resistors feature basic accuracy of 0.2% resolution for the 40-297 and 50-297, and 1% resolution for the 40-293 and 50-293.
