PXI precision resistor modules achieve high accuracy

Pickering Interfaces Ltdvisit website

 

Pickering Interfaces is expanding its range of PXI precision resistor modules with the introduction of two new models. The 40-261 is a two-channel resistor module offering excellent resolution and accuracy and is available in two resistance ranges. The resistor channels cover the range of 1.5ohm to 2.9kohm or 10ohm to 36kohm, with setting resolutions of less than 2mohm and 15mohm, respectively.

The model 40-297 is a range of high-density resistor simulators with a broader resistance range and higher channel count, but lower resolution than the 40-261. It is available in three standard configurations having resistance ranges of 1ohm to 230ohm, 2ohm to 13.5ohm and 3ohm to 1.5Mohm, with 18, nine and six channels, respectively. The six-channel version has a setting resolution of 0.125ohm.

Both models have software interfaces based on simple resistance calls for each channel, enabling users to just request the resistance value required. The modules include calibration data so that the driver can select the nearest value of resistance available.

Both modules occupy just one 3U PXI slot and accurately reflect the behaviour of precise resistor values since they use switched resistor networks.

David Owen, Business Development Manager for Pickering Interfaces, comments: "These resistor modules are part of our expanding range of resistor simulation solutions. The availability of a wide range of solutions allows users to select the best cost and performance solution for their application, and the use of simple resistance calls for control greatly simplifies the user's task in simulating resistors accurately regardless of which model is chosen. The new models complement the existing 40-260 and 40-262 PXI resistor simulators."
