Julien Sarrade from Keysight explains how to measure the power consumption of you IoT Device: how power is going into the LED display, or the supporting components and how much is eventually ending up in the RF signal. The measurement equipment is a Keysight N6705C Power Analyzer. This analyser provides unrivaled productivity gains for sourcing and measuring DC voltage and current into the DUT by integrating up to 4 advanced power supplies with DMM, Scope, Arb, and Data Logger features. The N6705C eliminates the need to gather multiple pieces of equipment and create complex test setups including transducers (such as current probes and shunts) to measure current into your DUT. The DC Power Analyzer also eliminates the need to develop and debug programs to control a collection of instruments and take useful measurements because all functions and measurements are available at the front panel.
