Why Choose the MTM-PM-1?
Built for Battery-Powered Device Testing
Exceptional transient response handles the demanding current spikes from cellular radios and other battery-powered devices. Exceeds 3GPP battery emulator specifications—no compromises when testing wireless devices.
RF-Clean Power Option
Switch to fully linear mode for noise-sensitive RF testing. No switching noise to contaminate your measurements. When thermal headroom matters more, enable the SMPS pre-conditioning stage.
Precision Measurement Built In
Monitor output current with 50µA resolution. Track device and equipment temperatures with the on-board sensor or optional K-type thermocouple. Analog current output available for third-party data acquisition.
Production-Ready Durability
Part of Acroname's Manufacturing Test Module (MTM) series, ruggedized for CM and OEM environments worldwide. All pin interfaces include reverse polarity and overvoltage protection.
Flexible Integration
Connect directly to a host PC via USB, or network with other MTM modules over I2C. Program with the BrainStem API (C++, Python) or run standalone embedded programs.
