Keysight Mobile Communication DC Sources

This video introduces Keysight Mobile Communication DC Sources, specialized for testing digital wireless devices such as smartphones, tablets, wearables, and RF communication modules. These DC sources provide clean, stable, and responsive power optimized for fast‑changing digital power demands. With precise voltage and current control, low ripple, and integrated measurement capabilities, they ensure accurate characterization across RF, wireless, and mobile‑device test workflows.

A fast transient response enables the supply to follow the rapid current changes typical of mobile devices during transmit/receive bursts, processor load steps, and wireless subsystem activity. This responsiveness helps prevent device shutdowns, brownouts, and false test failures. Low output noise ensures reliable RF performance, making these DC sources suitable for sensitive receivers, PA testing, and mixed‑signal wireless architectures. Built‑in voltage, current, and power measurements provide instant visibility into device behavior without requiring external meters.

Programmability through USB, LAN, and GPIB interfaces enables integration into automated test setups, allowing engineers to remotely control operating profiles, run automated sweeps, and capture performance data. With up to 20 A and 20 V per output—on one or two channels—for up to 100 W total power, these DC sources support diverse mobile‑device power configurations. Optional digital voltmeter and battery‑emulation functionality further enhances testing accuracy by simulating real battery conditions under dynamic loads.
 

Key features include:

• Fast Transient Response: Handles rapid load changes typical of smartphones and wireless devices.
• Low Output Noise: Provides clean, stable power with minimal ripple for sensitive RF measurements.
• Built‑In Measurements: Monitor voltage, current, and power in real time without external instruments.
• Programmability: USB, LAN, and GPIB interfaces support remote control and automated test integration.
• High Output Capability: Up to 20 A and 20 V per output, with one or two outputs and up to 100 W total power.
   

Keysight Mobile Communication DC Sources provide fast transient response, clean output, integrated measurement functions, and automation‑ready control—delivering precise, stable power ideal for verifying digital wireless devices and RF subsystems across R&D and production applications.
