调节探头补偿 To Adjust the Probe Compensation
频率补偿 Frequency Compensation
使用探头进行测试前,首先检查探头的
频率补偿,将其调至与所使用的示波器
匹配。一般示波器的前面板上都有一个
校准信号输出端,将探头连接至此信号
输出端(探头衰减设为 10X),令示波器
显示测试方波信号。将补偿调节棒插入
探头前端的补偿调节孔并顺时针/逆时
针转动调节棒直至示波器显示正确补偿
的方波(方波上方平整)。
Before taking any measurement using a probe, first check the
frequency compensation of the probe and adjust it to match
the oscilloscope used. Generally, the oscilloscope provides a
calibration signal output terminal at the front panel. Connect
the probe (set the probe attenuation to 10X) to the signal
output terminal to display a square waveform on the
oscilloscope. Insert the adjustment tool into the
compensation adjustment hole at the probe head and rotate
it clockwise/counterclockwise until the properly compensated
square waveform is displayed (flat-top square waveform).
