User Manual waveform. You can use this mode to reduce random noise. High Resolution (HR): This mode uses a kind of ultra-sample technique to average the neighboring points of the sample waveform to reduce the random noise on the input signal and generate much smoother waveform on the screen. This is generally used when the sample rate of the digital converter is higher than the storage rate of the acquisition memory. Note: "Average" and "HR" modes use different averaging methods. The former uses "Multi-sample Average" and the latter uses "Single Sample Average". Time Base: The oscilloscope digitizes waveform by acquiring the value of an input signal at discrete points.
The time base helps to control how often the values are digitized. Use the SEC/DIV knob to adjust the time base to a horizontal scale that suits your purpose. Push the UTILITY button and press Acquire softkey to set the acquisition parameter. Peak Detect Normal Acquire and accurately display most waveform. Detect glitches and eliminate the possibility of aliasing. Mode Average Reduce random or uncorrelated noise in signal display. The number of HR averages is selectable.
YT format shows the vertical voltage in relation to time (horizontal YT scale); XY format displays a dot between CH1 and CH2 each time when Disp Mode XY a sample is acquired, where the voltage or current of CH1 determines the X coordinate of the dot (horizontal) and the voltage or current of CH2 Roll determines the Y coordinate (vertical). For detailed information, refer to descriptions on XY format in the following text. Averages 4, 8, 16, 32, 64, 128 Select the number of averages by pressing F3 or F4. Memory Depth 4K, 8K, 16K, 4M, 8M The maximum single-channel display is 8M. 2.12.2. XY Mode The XY mode is used to analyze phase differences, such as those represented by Lissajous patterns.
The format plots the voltage on CH1 against the voltage on CH2, where CH1 is the horizontal axis and CH2 is the vertical axis. The oscilloscope uses the untriggered Normal acquisition mode and displays data as dots. The oscilloscope can acquire waveform in YT mode at any sampling rate. You may view the same waveform in XY mode. To perform this operation, stop the acquisition and change the display mode to XY. 2.12.3. Roll Mode In Roll mode, the waveform display rolls from right to left. No trigger or horizontal offset control of waveform is available during Roll Mode, and it’s only available when set to 100ms/div or slower. 2.13.
Display The waveform display is affected by settings of the oscilloscope. A waveform can be measured once it is captured. The different styles to display a waveform on the screen give significant information about it. Push the [Display] button and the following menu appears. 48 / 67 Options Settings Comments Options Settings Comments
