Small Size, Powerful Features

We pack a Programmable power supply, Counter/Timer, and a voltmeter into a package not much larger than a USB memory stick.

Furthermore, The programmability allows power supply waveform generation, power supply control from the other instruments, or just measurement decoding/unit conversion, all without programming!

The Power Supply
Any power supply can provide you with a steady DC voltage. The difficulty lies in generating the power supply waveforms you need to design for and validate against. PocketFrog is favorite among embedded programmers because it enables them to simulate battery charge/discharge, battery insertion, power drop-out, and automotive cold crank easily. This capability allows for the testing of load shedding and data backup software.

The Counter/Timer
Unlike many counter/timers, PocketFrog provides you with a simultaneous display of frequency, period, pulse width high, pulse width low, duty cycle, and total edge count. Any of these measurements can be used in calculations for power supply voltage or current. Additionally, if these measurements are sensor readings, you can utilize calculations to convert them to standard units, such as °C or PSI.

The Voltmeter
The Calculation features also allows validation of sensor measurements with the ability to enter conversion equations in the GUI.

Math functions allow users to define functions of any measurement, such as a voltmeter reading or frequency. This allows you to measure the voltage on a thermistor and not only measure the voltage, but also the temperature in real world units. For example, the pulse duty cycle from an automotive ECM can be measured and can display its representation in standard units, like LED brightness or vent angle.

The math functions within the host application can also establish relationships between instruments. For example, you can make measurements with the counter/timer and control the power supply voltage, which could control a motor. There are measurement safety limits, so if a measurement goes beyond specified bounds, you won’t subject your circuit to potentially dangerous voltage levels.

The PocketFrog comes to the rescue of those who have to work in small areas. Taking up only about 4 square inches of bench space, it gives back valuable bench space that older power supplies and counters take up. Even if you need the external power adapter, that can set on the floor out of the way. And if you choose the USB Power delivery version, you now can work where there is no access to AC power and still have a power supply that can deliver 40 Watts by using a 60 watt or greater USB power delivery power bank.
