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 [...]
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 [...]
Remote SENSE vs Local Sensing: A High-Current Buyer Checklist
Remote SENSE can reduce steady-state voltage error caused by power leads. Whether it is required [...]
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 [...]
High Precision Programmable DC Power Supplies: Accuracy vs Resolution
Display digits and setting resolution are not accuracy. Evaluate setting/readback accuracy, range, temperature coefficient, regulation, [...]
Programmable DC Power Supply Benefits: What Automation Adds
Programmability can make setpoints and records repeatable, reduce manual adjustments and integrate a supply into [...]
Variable DC Power Supply Manufacturers: 2026 Buyer Checklist
Build a supplier shortlist from documented models, required options and support. Manufacturer names alone do [...]
How to Choose a Programmable DC Bench Power Supply
Choose from the actual test sequence: required operating points, timing, source/sink behaviour and measurements. Confirm [...]
How to Use a Programmable DC Power Supply Safely
Begin with a known output-off state and verified limits. Automation should explicitly configure settings, read [...]
