1. Check your working environment. Use the site check form to guide your needs such that your instruments have maximum protection and minimum damage risk. Bench Instrument Site Check Table
  2. Comply with your ESD procedures and guidelines. If you do not have an appropriate form you can use this one. 10 Steps Daily ESD Self Check
  3. Refer to the specific Instrument Operation Manual. There are always guidelines on maximum power thresholds for RF and Microwave equipment and ESD and DC damage levels.
  4. Ensure connectors, adaptors & cables are the correct sizes and in good condition. Always use torque wrench and gauge tools and follow Keysight cable & connector care procedures.
  5. Check the input signal when applying these signals to sensitive measurement devices. Properly apply DC blocking capacitors or attenuators as necessary. When using external DC bias, make sure the external power supply is suitable. Check that it will not supply too much current, is within the stability tolerance and does not have significant switching transients. Follow the appropriate process for removing the DC Bias source from the test instrument to ensure no damage.
  6. Control your environment. Maintain temperature & humidity with a satisfactory range within the instruments specification and prevent large fluctuations.
  7. Periodically check and clean the air vents of your instrument. Inadequate airflow can result in excessive internal temperatures which can lead to instrument failure. If your instrument has fans, and perhaps fan filters, ensure that these elements are cleaned periodically.
  8. Check the recommended Calibration interval. Return the instrument to the Keysight Service Center for Calibration before the Cal due date is reached. Follow Keysight recommended Cal interval, send back instrument to Keysight Service Center for Calibration before Cal due date.
  9. Do not move the instrument if the disk/floppy driver is running. Always follow the defined procedures to power on and shut down the instrument. Many instruments use standard PC based operating systems that require the user to shut down in an appropriate way to prevent loss or damage to the instrument’s system configuration settings or saved data.
