DPO6000, MPO6000 Series Digital Fluorescent Oscilloscope Product Manual V1.3 By selecting the horizontal time base knob {turn the front panel horizontal time base knob}. By changing the acquisition method {press Utility-> Acquisition-> Acquisition Mode on the front panel} Note: The current waveform sampling rate is displayed in the status bar at the top of the screen. Horizontal control system Time base mode On the front panel, press the front-panel Utility-> Acquisition-> Display Mode menu. The F2 display mode control menu allows the user to select the desired time-base mode. DPO6000 / MPO6000 series oscilloscopes include three time base display modes:
YT mode, XY mode, and rolling mode [YT mode is the default]. YT mode In this mode, the Y-axis represents the amount of normal voltage and the X-axis repre- sents the amount of time. Note: In this mode, when the horizontal time base is set to 100ms or more, the instru- ment enters the scan mode. In YT mode, when the horizontal time base is set to 100ms/div or slower, the oscillo- scope enters the scan mode. In this mode, the oscilloscope first collects the data to the left of the trigger point, and then waits for the trigger condition. Then continue to com- plete the waveform to the right of the trigger point and display the currently acquired waveform data. Note:
It is recommended to set the “channel coupling” mode to “DC” in the scan mode to observe the low signal frequency. YT single window display mode 28
