Vertical calibration is the process of adjusting the vertical scale of an oscilloscope to ensure that the displayed signal amplitude matches the actual value. This usually involves using a standard signal source of known amplitude for comparison and adjustment.
Horizontal calibration is the process of adjusting the horizontal scale of an oscilloscope to ensure that the displayed signal frequency matches the actual value. Again, a standard signal source is required for calibration.
The trigger calibration criterion is to ensure that the oscilloscope can capture and display signal waveforms stably. This requires adjustments to the trigger mode and trigger level to achieve optimal triggering.
When calibrating an oscilloscope, it is recommended that the following steps be followed: first, consult the oscilloscope's instruction manual to understand the specific calibration methods and procedures; then, prepare the required calibration equipment and tools; perform step-by-step calibration in accordance with the manual's instructions and record the calibration results; and, finally, verify the calibration results to ensure that the oscilloscope's performance meets the specifications.
If you are not familiar with the calibration of oscilloscopes or encounter difficulties, it is recommended to contact the customer service or technical support team of the oscilloscope brand for assistance. Meanwhile, oscilloscope brands such as DYNAM provide online calibration guides and video tutorials and other resources to help you better complete your oscilloscope calibration.
