Rohde & Schwarz unveils new 5-channel power supply for test - Electronics360

Rohde & Schwarz's 5-channel test power supply signals a paradigm shift in ATE infrastructure: from serial single-domain to parallel multi-domain power delivery. Under Chiplet architectures, a single AI accelerator now houses 8 to 12 heterogeneous dies. Legacy dual-channel solutions multiply test cycle times; 5-channel parallel delivery lifts OSAT throughput by over 40%, directly improving packaging fabs' capital returns. Upstream ripple effects are already visible: inter-channel crosstalk suppression and dynamic load response are redefining power MOSFET and analog front-end design specs, forcing SiC/GaN device parameters to be rewritten. On compliance, the supply chain spans Taiwan, China (power IC foundry), Japan (sensors), and the US (FPGA control logic). A single export-control disruption at any node triggers 6 to 9 month delivery gaps. Competitively, Keysight's 8600 series still commands over 60% of the high-end ATE power segment. Rohde & Schwarz's likely wedge: cross-selling through its 5G/6G RF test customer base at a 30 to 40% price differential to capture mid-tier volume. Advantest may accelerate domestic integration to reduce external dependency. Within 18 months, 6 to 8 channel configurations become the AI-chip test standard, and test power supplies evolve from generic modules into DUT-coupled custom IP. If Rohde & Schwarz fails to integrate with Cadence or Synopsys simulation flows within 12 months, it forfeits the Chiplet test-ecosystem window.
