Functions and Advantages

8-Channel Modular Power Analysis Platform

The IT2705 is a powerful and efficient modular power analyzer that supports installation of up to 8 different types of modules (DC source, bidirectional source, regenerative load, SMU). With a full-color touchscreen, it allows real-time monitoring of all channel parameters and supports various meter view modes such as View1, View4, and View8. All modules can operate synchronously, enabling unified control and monitoring of input, output, and
load—avoiding the complexity of combining multiple bench-top instruments.
It is particularly well-suited for DC-DC module testing, integrating source and load into one frame to complete power supply, loading, measurement, and data acquisition in one unit. This significantly improves R&D efficiency. At the same time, the modular design supports flexible replacement and upgrades, meeting evolving testing requirements and helping to maximize long-term return on investment.

Scope view

All IT2705 modules are equipped with a scope sampling rate of up to 200 kHz, supporting high-bandwidth, real-time monitoring of DUT's voltage, current, and power waveforms. No external current probes, current clamps, or voltage probes are required, allowing complete capture of power-on/off transients, load switching, and interferences. This significantly simplifies the testing and improve analysis efficiency. Additionally, the IT2705 front panel is equipped with scope control keys (including trigger, single capture, run/stop, time base adjustment, etc.), making debugging more intuitive and efficient.

Arb Mode

The IT271XX / IT273XX / IT275XX / IT278XX modules are all equipped with high-performance Arbitrary Waveform (ARB) output capability, allowing users to define voltage, current, power, or resistance values that change over time for precise output sequences. This enables accurate simulation of voltage transients, dropout events, load pulses, and other dynamic behaviors at the DUT input. A variety of built-in standard waveform types are provided, including sine, pulse, trapezoid, exponential, step, ramp, staircase, and user-defined waveforms (supporting up to 128-point data import).ARB functionality is widely used in battery operating condition simulation, DC-DC stability testing, and communication device activation behavior analysis and so on.

Battery Simulation

The IT273XX / IT278XX modules support battery simulation functionality, accurately replicating the voltage-current behavior of real batteries under different states of charge (SOC). Users can set key battery parameters such as open-circuit voltage, internal resistance and capacity. The system dynamically adjusts the output voltage based on the DUT’s current request, simulating the real charge/discharge process of a battery. Compared to real batteries, the simulator offers higher repeatability, making it especially suitable for scenarios such as development of battery powered devices , validation of power management IC, and more.
