The 40-261 is a new generation of PXI based programmable resistors that features high resistance setting resolution and excellent resistance stability and accuracy through the use of innovative switching networks and software correction techniques. Each module supports two identical resistor channels that can be set to values of between 1.5Ω to 2.9kΩ or 10Ω to 36kΩ with a precision of better than 2mΩ (40-261-001) or 15mΩ (40-261-002) making the 40-261 ideal for simulating sensors that can be accurately controlled to fine values. Thanks to the use of innovative technology the 40-261 ensures all resistance values can be set – no missing values because of switch resistance or resistor tolerance. Applications include air bag squib, strain gauge and temperature dependent resistor emulation.
