RigExpert REAMP Power Consumption Logger for Low-Power Electronics

RigExpert REAMP Power Consumption Logger helps developers measure and analyse the electrical demand of low-power electronics. It combines one current measurement channel with two voltage channels, allowing consumption and selected circuit voltages to be recorded together. USB connectivity links the instrument to a computer for control, graphical analysis and data logging, supporting investigation of operating modes and changes in device behaviour.

Current and Voltage Measurement

The RigExpert REAMP current channel measures from 10 µA to 1 A, while two voltage inputs monitor points of interest on the device under test. Sampling is selectable from 10 Hz to 10 kHz, with the highest rate available in single-channel operation only. Instantaneous readings, averaged values and zoomable traces help users examine short events alongside longer operating periods without relying solely on a multimeter reading.

Adjustable Power for the Device Under Test

RigExpert REAMP can supply the connected device with 1.8–5.2 V in 50 mV steps, supporting repeatable tests at selected operating voltages. The instrument receives power through USB and includes a rechargeable lithium-ion battery to support cases where DUT consumption exceeds 500 mA. Output-current protection limits are separate from the 1 A current measurement range and must not be treated as additional calibrated measurement capacity.

Synchronisation, Logging and Analysis

TRIG and SYNC connections coordinate acquisition with external equipment or the target board. Timed and continuous measurement modes support different test durations, while REAMP software provides graph navigation, consumption averaging and analysis of saved logs. Data can be reported in graphical or tabular form and exported as CSV or XLSX files. Battery-life estimation tools help relate measured consumption to an intended autonomous power source.
