5G mmWave Power Supply Testing: Lead Drop and Remote SENSE
In RF validation, lead resistance can create a difference between the programmed voltage and the DUT supply rail. Measure the DUT voltage during the r…
RFIC Validation: How a 0.3V Lead Drop Changes Your Test
A 60A current through a 5mΩ total force-loop resistance produces a calculated 0.30V drop. On a nominal 3.30V rail that leaves 3.00V at the DUT. This i…
High-Current Programmable DC Power Supply: Remote Sense and Wiring Guide
Remote SENSE can reduce steady-state voltage error caused by power leads. Whether it is required depends on loop resistance and the DUT voltage tolera…
Remote SENSE on a DC Power Supply: 4-Wire Wiring and Limits
Remote SENSE uses separate feedback leads to regulate voltage near the DUT. It compensates power-lead drop only within the instrument’s documented lim…
