A new class of PXI/PXIe simulation modules delivers real-world analog signals at up to 130,000 RPM, enabling ultra-precise testing of high-speed servo systems in mission-critical applications.
Pickering Interfaces has expanded its 41-670 (PXI) and 43-670 (PXIe) resolver simulator family to support high-speed simulation of up to 130,000 RPM. Designed to meet the rising demands of aerospace, automotive, and defense sectors, these modules offer best-in-class performance for testing embedded control systems reliant on high-speed resolvers and variable differential transformers (LVDT, RVDT).
The key features are:
- Available in 2- or 4-bank configurations (model dependent)
- Each bank simulates 5-, 6-, or dual 4-wire resolver/VDT signals
- Supports up to 4 or 8 simulation channels per module
- Ideal for compact, high-density testing of multi-axis systems
Modern embedded control systems require accurate high-speed resolver testing to detect subtle software bugs and validate dynamic behavior. Pickering’s new modules simulate multiple resolver pole pairs with up to 80kHz excitation frequencies—ensuring greater signal fidelity, lower noise, and superior responsiveness. Unlike FPGA-based emulation, these modules employ onboard transformers to produce true analog output, delivering real-world accuracy and high-resolution angle simulation even at top rotational speeds.
The integrated relays allow short/open circuit simulation per channel, minimizing external hardware needs for fault injection. Additionally, programmable phase delays help engineers simulate sensor imperfections, aiding robust software validation. The new high-speed PXI resolver simulators bring unmatched realism and scalability to embedded servo system testing—delivering compact form factor, high signal fidelity, and configurable fault insertion in a single module. Backed by a three-year warranty and long-term support, it’s a future-ready solution for mission-critical hardware-in-the-loop (HIL) testing.
