请问LED灯管需要测试阴极电压，电流吗？
背景描述：一根LED灯管，替换传统荧光灯管，兼容电子镇流器。看到一份测试计划上要求25KHZ下测量DCVoltage，DCcomponent（直流分量）还要测试阴极左右两端的电压，电流，直流电压，直流分量（CathodeMeasurements (left/right)），现在有一台高频基准镇流器问题：直流电压怎么测试？测哪个位置？阴极两端的电压电流怎么测？测哪个位置？直流分量是要计算的，但是实测的直流电压是平均值还是峰值？Sample Number
Target Lamp17W/24T8
Circuit ApplicationInstant Start (IS)
Reference Ballast60Hz25kHz
Lamp Measurements:
Voltage, V
Current, A
Power, W
DC Voltage, V dc
DC component1,% dc
Cathode Measurements(left/right):
Voltages, V--N/A
Currents, A--N/A
DC Voltages, V dc--N/A
DC components1,% dc--N/A
1 The calculated DC component ofthe voltage waveform (% dc) equals its DC measurement (V dc) divided by itsRMS measurement (V) multiplied by 100.
求指教谢谢
