Overview EN 3 Overview 3.1 Preparation before testing Before conducting testing, users need to first prepare as follows: 1. Power on 2. Warm up (run the oscilloscope for at least 30 minutes) 3. Self correction Power on When the oscilloscope is powered on, press the power button in the lower left corner of the front panel to start the oscilloscope. During the startup process, the oscilloscope performs a series of self checks, and the startup screen appears after the self check is completed.
If the oscilloscope cannot start normally, please refer to the "Troubleshooting" section in the “DPO7000 User Manual” to identify and resolve the cause, and then perform self calibration and performance testing. Preheat Turn on or run the oscilloscope for at least 30 minutes. Self correction Before calibration, please ensure that the oscilloscope has been preheated or operated for more than 30 minutes. 1. Firstly, confirm to disconnect all input channels. 2. Enter the oscilloscope function, click on [Utility] -> More -> System -> SelfCal menu and follow the instructions on the display screen to perform calibration. Calibration takes approximately 2-3 minutes. 3.
Under the oscilloscope function, click on the [Acquire] -> Acquisition method menu, set the acquisition mode to average, and set the average number of times to 16. 4. Set the vertical gear of each channel to 2 mV/div and check the offset degree of each channel waveform. If the deviation is greater than 0.5 div, recheck the surrounding area for interference signals, etc., and perform calibration again after checking for errors.
