60 6000L Series Oscilloscopes Service Guide4 TroubleshootingTable 12 Equipment Required to Troubleshoot the OscilloscopeTo check out the oscilloscope1 Disconnect any external cables from the front panel.2 Disconnect the power cord, then remove the cabinet following the instructionson page 73 for Keysight 6000L Series models.3 Connect the power cord to the rear of the oscilloscope, then to a suitable acvoltage source.The oscilloscope power supply automatically adjusts for input line voltages inthe range of 100 to 240 VAC. Ensure that you have the correct line cord. Thepower cord provided is matched to the country of origin.TEquipment Critical Specifications Recommended Model/PartDigital multimeter Accuracy ±0.05,% 1 mV resolution Keysight 34401AOscilloscope Capable of measuring ≥ 500 MHz signal. 1MΩ input impedance.KeysightDSO6102A, MSO6102A,DSO6102A, or MSO6104ACAUTION USE AN EXTERNAL FAN TO AVOID OVERHEATING COMPONENTS !When you remove the oscilloscope cover and main shield, use an external fan to provide continuous airflow over the heat sinks. Air flow over the heat sinks is reduced when the cover and main shield areremoved, which leads to higher than normal operating temperatures. Have the fan blow air across thesystem board where the heat sinks are located. Otherwise, damage to the components can occur.WARNING HAZARDOUS VOLTAGES EXIST — HIGH VOLTAGE IS PRESENT ON DSO6000L SERIES POWER SUPPLYHEAT SINKS !The power supply heat sinks of the 6000L Series oscilloscopes are at a high potential. This presents anelectric shock hazard. Protect yourself from electric shock by keeping this area covered or by not comingin contact with the heat sinks when the power cord is attached to the oscilloscope!CAUTION Use only the power cord that came with the oscilloscopeThe power cord provided is matched to the country of origin of the order.
