R&S Essentials high-precision
power supplies for peak power By Shivam Arora, Product Manager power supplies & LCR meter, Rohde & Schwarz
he R&SNGL, R&SNGM and R&SNGU have easy-to-use interfaces, fast load regulation and high-speed logging of measured values. When combined with different application tools, they are ideal for optimising and testing IoT and mobile devices as well as characterising semiconductors.
T Demand for mobile IoT devices continues to
grow. Energy efficiency is a key requirement along with connectivity. The devices must deliver optimal performance, consume minimal amounts of energy and be as durable as possible.
High-precision power supplies for IoT applications
Along with rapid voltage and current fluctuations during operations, minimal power consumption in standby mode also makes testing a challenge for many energy-efficient devices. R&S Essentials high-precision power supplies address these challenges with exceptional accuracy and rapid load recovery times, making them ideal for the complex IoT applications. The integrated Rohde & Schwarz ammeter can measure current drain from nanoamps to amperes in a single pass, with no additional measurement sweeps needed. The R&SNGU series has current
resolution up to 100 picoamps and is ideal for applications with quiescent current levels over 100 nanoamps, including NB-IoT, LTE-M, 2G, BLE, ZigBee and Wi-Fi.
Identify battery-intensive
processes faster The battery cycle and battery modelling tools let users create battery models with defined charging and discharging for pulsed and
constant current sources. The tools are ideal for battery characterisation and qualification testing. The battery simulation function can realistically simulate the power supply in battery-operated devices.
The integrated ammeter records the power consumption of an IoT device in real time while the logging and charting tool saves and displays the information in a live chart to help identify battery-intensive processes and minimise power consumption.
