A Keysight oscilloscope is an instrument used to measure and display the waveform of an electrical signal. When using an oscilloscope, the setting of the trigger level is very important because it determines when the oscilloscope starts acquiring and displaying waveforms. In this article, we will discuss the importance of Keysight oscilloscope trigger level setting and how to set it correctly.
The trigger level refers to the voltage level at which the trigger triggers and starts acquiring waveforms. Setting the trigger level correctly ensures that the waveform is displayed stably on the screen without runout or distortion. The trigger level is usually set according to the characteristics of the signal being measured, such as the amplitude, frequency, and waveform shape of the signal.
When setting the trigger level, you first need to select the appropriate trigger mode, such as edge trigger, pulse trigger or ** trigger, etc. The position of the trigger level and the voltage level are then adjusted according to the characteristics of the signal being measured, so that the trigger can accurately capture the desired signal waveform. Typically, the trigger level should be set at the beginning of the signal waveform to ensure that the waveform is displayed stably on the oscilloscope screen.
In addition to the basic trigger level settings, advanced trigger settings are sometimes required, such as setting the trigger delay, trigger pulse width, and trigger slope. These advanced settings can help users capture and display specific signal waveforms more precisely, especially for complex signals or noisy noise.
In conclusion, the correct setting of Keysight oscilloscope trigger levels is important for accurately visualizing and analyzing the signal waveform. By understanding the characteristics of the signal under test and setting the appropriate trigger mode and level as needed, you can ensure that the oscilloscope can stably display the desired waveform and help users better perform signal analysis and troubleshooting.
