Concerto for IoT: Maximizing Battery Life

Monitoring battery drain is critical to designing and building IoT devices. Whether it’s your first project or your magnum opus, the right conductor provides insight and improves device performance. Rely on Keysight low power test solutions to be your conductor. These powerful analysis tools measure dynamic current, current pulses and sleep/wake cycles to visualize and characterize your device. When everything works in concert, you get a clear picture of battery life

RESOLUTION & ACCURACY

  • Measurement resolution should be more precise than the IoT device. But resolution is not enough—a large accuracy error can leave you with a false reading 

  • The resolution of the conductor’s trained ear picks up every nuance in a piece of music. And because he has perfect pitch, the accuracy error is very low. The patron in the front row hears the same music, but he’s missing the subtleties

WIDE DYNAMIC RANGE

  • IoT devices spend most of the time in low-power mode, with high peaks during active state. Your test instrument needs to measure this wide range, so make sure the instrument’s measurement range encompasses the min/max currents of the device.

  • A conductor evaluates a wide dynamic range too, from the faintest strings of the harp to the powerful sound of a trumpet. And if a musician in the orchestra misses even the quietest note, the conductor will hear it. 

CURRENT PULSES & SLEEP/WAKE CYCLE

  • Most of the time your IoT device is idle. Then it kicks into action, does its work, and goes right back to sleep. Your test instrument needs to measure these long standby periods and extremely short pulses

  • The conductor listens to the music and knows just the right moment to intersperse a long period of quiet flute with staccato percussion

COST-EFFECTIVE TEST 

  • Be efficient—keep testing costs as low as possible while still maintaining accuracy

  • Be efficient—keep testing costs as low as possible while still maintaining accuracy

MULTIPLE DEVICES & TEST POINTS

  • High-volume manufacturing requires a high-throughput test instrument that can analyze multiple devices and specifications at once 

  • A good conductor can lead a seven-piece chamber group or a seventy-piece orchestra with ease, depending on what is needed

RANGE OF SOLUTIONS

  • Every application is unique, and a one-size solution does not fit all. Choosing the right test instrument can save time, budget, and improve results

  • A talented conductor knows how to tease out the best performance, whether in a symphony hall or a high-school gymnasium
