TEWKSBURY, Mass. - Pickering Interfaces has introduced three PXI/PXIe analog output modules designed for signal sourcing and sensor simulation in functional test and hardware-in-the-loop (HIL) applications.

The new modules include multi-channel waveform generators, precision digital-to-analog converter (DAC) outputs, and high-density thermocouple simulators. The modules are designed to provide embedded controllers with simulated analog, sensor, and waveform conditions from compact, modular test systems.

The 41-770 PXI and 43-770 PXIe DAC modules provide up to four isolated analog output channels in a single 3U PXI/PXIe slot. Each channel is independently programmable across multiple voltage and current ranges, with voltage outputs up to ±40 V and current outputs up to ±20 mA. The modules can simulate open-circuit conditions for fault-injection testing and include hardware interlocks to help protect the device under test (DUT) and test system.

The 41-625 PXI and 43-625 PXIe waveform generators provide up to 32 independent output channels in a single 3U PXI/PXIe slot. The modules support waveform generation from DC to 300 kHz and can simulate accelerometers and other multi-channel stimulus conditions. Each channel includes independent memory for sine waves, standard waveforms, and user-defined arbitrary waveforms, with software-controlled frequency adjustment using direct digital synthesis. Trigger functions enable external instruments to initiate waveform generation and frequency sweeps.

The PXI 41-761A analog output and thermocouple simulator modules provide microvolt-level thermocouple sensor simulation with built-in fault insertion. The modules provide independently isolated, two-wire low-voltage outputs covering common thermocouple ranges and support multiple cold-junction configurations. With up to 32 fully isolated channels per slot, the modules enable high-density thermocouple simulation without external switching or system expansion.

The modules support HIL simulation, functional test, sensor simulation, production test, and fault-injection applications. PXI and PXIe variants include driver support for Windows and Linux operating systems, along with APIs for C, Python, C#, MATLAB, Simulink, and LabVIEW.
