Current Measurements of MCU Low-Power Mode Transition with CX3300

Application Notes

The microcontroller (MCU) is at the heart of a low-power device, and the MCU offers various powersaving modes to meet the demands of long battery life. However, engineers are required to carefully study the behavior of a low-power device and often perform complex debugging operations in order to realize the device’s appropriate performance while power saving at the same time.

 

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.

 

The CX3300 Series also features useful analysis capabilities such as Automatic Power and Current Profiler, Power Measurement Wizard, FFT Analyzer and Statistical Analysis functions, which accelerate the analysis of the measurement data without the need to use external analysis utilities.

 

With this new and powerful analyzer, you can achieve critical mission on power and current consumption reductions by precisely measuring, previously unmeasurable or undetectable, wideband low-level current waveforms.
