Oscilloscope positive duty cycle search

We have shared with you the pulse width search function of the ZDS2022 oscilloscope. The oscilloscope search function is practical and convenient. However, some users are not very familiar with the search function of the ZDS2022 oscilloscope. In fact, the ZDS2022 oscilloscope has a powerful full hardware search function, which is not only fast, but also includes multiple search types such as edge, pulse width, rise/fall time, cycle/frequency, duty cycle and runt.

　　In this video, we will witness the positive duty cycle search function of the ZDS2022 oscilloscope.

　　We press the [Horiz] key to set the storage depth to the maximum value of 112Mpts, turn the horizontal time base knob to adjust the horizontal time base to 5ms/div, press the [Measure] key, open the search setting option, set the search enable to ON, set the search mode to positive duty cycle, set the qualifier to less than, set the less than value to 30%, and press the [Single] button. We can see the search results in the upper left corner of the screen.
