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.
Sequence Mode
Supports Sequence waveform mode, allowing multiple different types of waveform segments (e.g., DC output, trapezoidal waveforms) to be combined into a complete sequence file and executed automatically in a predefined order. Each segment can be individually configured with duration and repeat count. It is suitable for simulating scenarios where a DC-DC power module transitions from normal supply to fault or abnormal conditions, as well as for testing response to multi-step load variations. It significantly enhances test automation and repeatability.
Const Dwell Arbitrary (CDARB)
Supports importing user-captured data to generate arbitrary waveform output with constant dwell time. In this mode, all waveform points use a uniform dwell time and are executed sequentially at equal intervals. It supports importing up to 8000 points of voltage, current, power, or resistance waveform. Users can freely set the output duration, with the system defaulting to the fastest slew rate between points.
