Pickering 40-295-121 PXI Programmable Resistor Module
The Pickering 40-295-121 programmable resistor module is a compact solution designed for precision resistance synthesis in modular test systems. The module supports PXI Specification 2.2 and fits standard 3U PXI and cPCI chassis. It uses a 33 MHz 32-bit backplane interface. The 40-295-121 PXI resistor module provides 1 Ohm resolution that enables precise incremental adjustments for resistance chain configurations. The module uses accurate fitted resistors that maintain ±0.5% tolerance from 0 Ohm to 1 M-Ohm ranges. The tolerance changes to ±1% for resistance values above 1MOhm ranges. The 16-bit configuration provides 2 Ohm residual resistance values and the 24-bit alignment provides 3 Ohm residual resistance values. The 40-295-121 PXI resistor unit offers 8-bit and 12-bit configuration that provides 1.5 Ohm residual resistance values.
The resistor module supports a maximum switch voltage rating of 100 V. The module handles a maximum switch current of 0.5 A during active switching operations. The design supports a maximum carry current of 1.0 A under continuous load conditions. It supports a maximum power rating of 0.5 W during resistive operation. The operating temperature range spans from 0°C to +55°C. The module tolerates humidity levels up to 90% non-condensing. The module supports operational altitudes reaching 5000 m and supports storage temperatures from -20°C to +75°C. The 40-295-121 resistor module achieves an operate time below 0.5 ms. The release time also remains below 0.5 ms for consistent switching performance. The unit withstands more than 1x10^8 operations at low power loads and more than 1x10^6 operations at full power loads. The PXI resistor module contains various CE and UL certifications for electrical and mechanical reliability. Local Bus support is not implemented. Trigger Bus and Star Trigger support is also not implemented for this module.
The Pickering 40-295-121 PXI programmable resistor module operates within 3U PXI and 3U cPCI chassis without modification. The module also supports installation in legacy peripheral slots of PXI Express systems. The hybrid peripheral slot compatibility supports broader system integration flexibility. The stable switching behavior supports repeatable calibration tasks for test benches. The consistent resistance synthesis function supports deterministic control schemes within modular instrumentation architectures requiring impedance states. The 40-295-121 PXI programmable resistor unit supports workflows that require predictable resistance construction under software control.
