Solutions for Internet of Things Testing By Rigol, Available from Instruments 4 Engineers

 What is IoT?  In basic terms it is the concept of connecting any device with an on and off switch to the Internet (and/or to each other).The phrase was originally coined back in 1999 by Kevin Ashton and later was discussed more in depth in 2009Technology has changed drastically since 1999 including the challenges engineers face in regards to developing and testing the latest technology and the exciting ideas tomorrow.

Iot Power Analysis

Debug & Analysis of Power Requirements:

Deciding the balance between function and battery life is one of the most important steps in IoT Development. Some of the questions engineers often struggle with questions like should I use a larger battery or should we reduce radio communication?

Learn our approach to understanding your power usage and avoid design requirement changes that can derail your IoT product. You can avoid derailing your Internet of Things product by understanding power usage and avoiding design changes.  

Increase your knowlege of how your IoT project will consume power and shorten battery life start with a test regiment of baseline power analysis. Engineers should consider  the nominal power usage, the boot up energy requirement, and the power used by peripherals that will be needed. Engineers can reduce the risk of design changes late in the project by iteratively testing power usage while updating the software and hardware configurations on their platform.   In the video below Rigol demonstrate IoT Power Managerment.

Radio Internet of Things Power Usage 2.4GHz:

One of the important power uses of an IoT device is it’s RF output power, but how much power does it take to run the entire RF peripheral and how do you optimize it? Evaluate RF power throughout development and characterize power use in different modes.

Whatever your IoT passion, your product likely connects wirelessly to a network, sensors, or both. In the 2.4 GHz band Bluetooth, Wi-Fi, Zigbee many other wireless protocols compete for data bandwidth. Evaluating the battery implications of exchanging RF data is an important element in understanding the overall operation of any IoT device. Using a IoT development platform we compare methods for measuring the power consumed by different radio operating modes.  Instruments used in the below video and application notes are Rigol DSA800 Series Spectrum Analyzers,Rigol DS/MSO4000 Oscilloscopes, Rigol DP800 Power Supplies, and R1002C current probe.




The Rigol DSA800 series spectrum  analys

ers maybe suitable for some parts of Zigbee applications. Although demodulation of Zigbee signals are not possible,frequency analysis is possible and monitoring the 3rd harmonic of 2.4 GHz signals (excludeds Rigol DSA815).

Wireless Sensor Characterization

Characterize ASK/FSK Sensor Communication:

Many IoT sensors connect wirelessly to the main application platform over one of many ASK or FSK protocols from 800 or 900 MHz bands up through 2.4 GHz. Characterizing how these sensors perform in real world environments is critical to understanding how best to implement network communication, range, and sensor deployment.

Even the simplest sensors and communication protocols need to be characterized before sending an the device to market. Characterize error budgets for timing, radio power, and modulation settings in a real environment before critical baseband data errors effect performance. Use a Spectrum Analyzer’s real time bandwidth to analyze the RF signal.
