Meaning
Precision power profiling hardware combined with synchronized software logging enables continuous current and voltage measurement during low-power device optimization. The Otii Arc acts as both a programmable power supply and a high-speed sampling measurement unit for battery-operated hardware. Current measurements ranging from nanoamperes during deep sleep to amperes during active radio transmission are captured at high sampling frequencies.
Hardware engineers utilize these measurements to isolate energy-draining software loops and quantify energy budgets. The unit integrates with build pipelines to automate power regression testing during firmware development.
Measurement Precision
Dynamic range switching allows capture of rapid current spikes without losing baseline sleep state accuracy. Operating the Otii Arc reveals microsecond-level power transients caused by internal module wake-up sequences. Sub-microampere accuracy during sleep phases ensures realistic battery lifetime projections for low-duty-cycle IoT devices.
High sampling rates prevent aliasing of fast RF power bursts.
Power Emulation
Programmable output voltage profiles simulate real battery discharge curves under dynamic load conditions. Utilizing the Otii Arc allows developers to recreate high internal resistance scenarios seen in depleted lithium primary batteries. Testing under emulated low-voltage conditions exposes brownout behavior without physically degrading chemical cells.
Controlled voltage stepping confirms firmware graceful shutdown routines under depleted battery conditions.
Automated Pipeline
Scripting interfaces allow automated execution of current profiling tasks within continuous integration environments. Integrating the Otii Arc into automated test racks ensures every firmware release is validated against baseline energy limits. Automated alerts flag unexpected increases in average power consumption before code reaches production.
Continuous power monitoring prevents regression bugs from reaching deployed hardware.
