The core performance indicators of high current generators include output current range, current stability, response time, and waveform quality. The output current range must be selected based on actual needs; too small a range will not meet testing requirements, while too large a range will waste resources. Current stability directly affects the accuracy of test results, especially important in precision measurements. Response time reflects the device's ability to quickly adjust to current changes, which is crucial for scenarios requiring frequent current adjustments. Waveform quality relates to the purity of the current; a high-quality waveform reduces interference to the device under test.
