Bluetooth® Low Energy Current Consumption using the CX3300

Application Notes

New information technology, the Internet of Things (IoT) is changing our lives. The Bluetooth low energy (BLE) standard is aimed at IoT applications and dramatically extends battery life. In order to implement it, there is a need to reduce the amount of unused power from existing devices, and engineers are therefore exploring component level dynamic current consumption, which is difficult to measure, especially for lowpower devices used in IoT enabled products, because of the limited dynamic range, large measurement noise and limited bandwidth.

The CX3300 Series Device Current Waveform Analyzers allows you to visualize wideband low-level, previously unmeasurable or undetectable, current waveforms. The mainframe has either 2 or 4 channels to receive signals from the current sensors and digitize them by a maximum of 1 GSa/s and a 14-bit or 16-bit wide dynamic range. There are five current sensors that can detect a wide range of dynamic currents from 150 pA level up to 100 A, with a maximum of 200 MHz bandwidth.
