Calibrating and Adjusting
This chapter explains how to adjust the oscilloscope for optimum
operating performance. You should perform the hardware adjustments
and self-calibration according to the following recommendations.
• Perform hardware adjustments every 12 months or after 2,000 hours
of operation.
• Perform self-calibration:
• every 6 months or after 1000 hours of operation
• if the ambient temperature is >10 °C from the calibration temperature
• if you want to maximize the measurement accuracy
The amount of use, environmental conditions, and experience with other
instruments help determine if you need shorter adjustment intervals.
In this chapter, you will:
• Adjust the power supply
• Perform self-calibration
• Adjust the display
Let the Equipment Warm Up Before Adjusting
Before you start the adjustments, let the oscilloscope and test equipment
warm up for at least 30 minutes.
