New two- and four-channel modules combine complex stimulus generation, lower per-channel costs and long-term support

MUNICH, Nov. 10, 2026 /PRNewswire/ — Pickering Interfaces today launches its 41-621 PXI and 43-621 PXIe arbitrary waveform generators at electronica in Munich. Designed for applications including avionics functional test, full authority digital engine control (FADEC) testing, multi-channel sensor simulation and legacy automated test equipment upgrades, the modules deliver up to four channels in a single 3U slot.

The new product family offers the highest PXI/PXIe channel density for arbitrary waveform generators operating above 20 MHz. With twice as many channels per slot as comparable two-channel solutions, the four-channel models help engineers reduce chassis space and system cost. Pickering estimates a per-channel cost advantage of approximately 40% for the four-channel version over competing solutions.

“Engineers need to reproduce increasingly complex signals while keeping test systems compact, affordable and supportable,” said Tom Sarfi, Product Line Manager at Pickering. “These modules bring more waveform-generation channels into a single slot, helping customers reduce system footprint and cost without sacrificing stimulus flexibility. Combined with our long-term support, they provide a practical foundation for new test systems and legacy ATE upgrades.”

Each channel features a 16-bit digital-to-analog converter operating at up to 250 MSamples/s, 128 MSamples of onboard waveform memory and output amplitudes up to 20 Vpp into a high impedance load. The modules generate sine waves up to 40 MHz and support standard and arbitrary waveforms, enabling engineers to reproduce complex sensor signals and other test stimuli.

Built-in capabilities include AM, FM, chirp, frequency- and phase-shift keying, pulse-width modulation, and frequency sweeps. Channels can be synchronized and phase aligned within a module and across multiple modules, supporting coordinated stimulus generation for multi-channel test applications.

Available in two- and four-channel versions, the arbitrary waveform family gives engineers a choice of PXI or PXIe platforms. The PXI models also operate in Pickering’s LXI and LXI/USB modular chassis, providing Ethernet- or USB-controlled alternatives. Software support includes LabVIEW, Python and C#, alongside a soft front panel for configuring common waveforms, importing custom waveforms and setting up sweeps.

The modules include a standard three-year warranty and Pickering’s long-term product support, typically spanning 15–20 years or more. For more information, visit www.pickeringtest.com.
