Abstract

The method includes the following steps: Agilent86100A wideband samploscope with a double microwave diode balance sampling head circuit is selected as pulse signal generator; plug-in component is installed; the voltage is set in -300mV-50mV or +50mV-+300mV; Agilent86100B wideband samploscope for TDR signal is selected to match the delay of Agilent86100A wideband samploscope; a time domain reflectometer plug-in is installed; the trigger signal of Agilent86100A wideband samploscope is sent out; the signal triggering end of Agilent86100A wideband samploscope is connected to the TDR signal generating end of Agilent86100B wideband samploscope; its cable is connected to the input end of Agilent86100A wideband samploscope; adjusting vertical sensitivity and horizontal sensitivity of Agilent86100A wideband samploscope; setting the offset voltage of Agilent86100A wideband samploscope as zero; adjusting the delay time until Agilent86100A wideband samploscope generates high speed pulse signals. Its equivalent step impulse source has 8ps rise time.
