Low Power Consumption
Low power consumption
The ENERGY STAR® program is designed to help businesses and individuals save money and protect the climate through superior energy efficiency. Measurements of standby, idle state, and sleep mode power may be required as well as the normal on mode power.
Tektronix power analyzers provide accurate measurements of both power and energy consumption in watt-hours (W-h). Simultaneous measurements of power, power factor, total harmonic distortion and harmonics are available, as required by ENERGY STAR. Features such as a color graphics display and 1- click set up help speed measurements while the included PWRVIEW PC software captures data for seamless analysis and reporting.
Power consumption measurements on portable battery operated devices
For battery operated IoT devices, or medical sensors, it is must to know the battery life to secure operation. For wearable gadgets it is also good to know how long the device will operate. This requiers knowledge of the current consumption profile of the device and the battery which is used. This application note describes a combination of instruments to create battery model and measure power consumption.
Ulta low Power measurements of wireless sensors
the currrent consumption of a wireless battery operated sensor, in eg IoT applications, has several stages. From deep sleep levels with hardly consumption up till a stage where data are transmitted and the consumption can be decades higher as in deep sleep. The several stages could be short in time, and can include several current decades. To measure this current consumption profile, a high sampling current meter is required, which can also measure currentls on several decades.
