Hello everyone, previously we used the Nth edge trigger function to trigger an under-amplitude signal. So, what exactly is Nth edge triggering? Today we will discuss the Nth edge triggering of the ZDS2022. The Nth edge trigger of the oscilloscope, as the name implies, triggers on the Nth edge, but it is necessary to determine … Read more
How do we calculate the positive duty cycle for such a narrow pulse on the screen? We set the horizontal time base to 200us/div, allowing us to observe its two cycles. Since the pulse is too narrow, using traditional manual measurement with cursors is not the best option. What methods can the ZDS2022 provide? The … Read more
Some signal features are difficult to determine in the time domain, but can be easily analyzed in the frequency domain. For example, the noise characteristics of a DC power supply require the use of Fourier analysis to convert time-domain signals into frequency-domain signals. The ZDS2022 oscilloscope features up to 4Mpts of FFT analysis sample points, … Read more
Are you still searching for the keys on the oscilloscope’s front panel one by one to find the storage function? Then starting a complicated series of operations just to store a waveform! The ZDS2022 oscilloscope will brighten your day with its one-button waveform storage! At this moment, the oscilloscope screen displays a triggered waveform of … Read more
For different channel input signals, sometimes we want one channel signal to meet one condition while another channel waveform meets a different condition, achieving a logical “AND” combination for the channels. For example, how can we trigger channel 1 on a high level while triggering channel 2 on a rising edge? The ZDS2022 oscilloscope not … Read more
Hello everyone, in the previous episode of our 100-episode practical video series, we shared the pulse width search function of the ZDS2022 oscilloscope. The oscilloscope’s search function is practical and convenient. However, some users are still not very familiar with the search function of the ZDS2022 oscilloscope. In fact, the ZDS2022 oscilloscope has a powerful … Read more
During the technical exchange meetings of oscilloscopes, we learned that some customers need to understand the rise slope of CAN signals. They usually measure some values and then calculate manually. The ZDS2022 oscilloscope will save you a lot of time by displaying the results directly without manual calculations! The operation is very simple. First, connect … Read more
When analyzing the characteristics of a signal, it is necessary to examine the measurement results of various parameters of that signal. The ZDS2022 oscilloscope is equipped with the capability to measure 51 different parameters. This video demonstrates this function in practice. Typically, when analyzing the characteristics of a signal, we rely on the measurement results … Read more
To measure the functionality of an oscilloscope, the trigger module is generally a point of focus. In fact, the triggers used internally in oscilloscopes are divided into analog triggers and digital triggers. The ZDS2022 oscilloscope uses a digital trigger, which results in low signal jitter and high trigger sensitivity, with dynamic adjustment available! We discovered … Read more
The ZDS2022 oscilloscope’s hundred technical exchange meetings are still in full swing. Through communication with a certain customer, it was learned that one of their samples may have abnormal waveforms at the moment of power-up. Today, we will use the ZDS2022 to capture the power-on signal multiple times and observe the real-time comparison of multiple … Read more
