Roll: In Roll mode, the waveform display rolls from right to left. Trigger or horizontal offset control of waveforms is available during Roll Mode, and it‟s only available when set to 100ms/div or slower. Press Time->Mode to change the display mode to Roll , the time/div will be changed to 100ms/div automatically. Scan: In Scan Mode, the waveform display scan updates from left to right. In Scan mode, trigger and horizontal offset control of waveforms are available during Scan Mode. This mode is only available when set to 100ms/div or slower. Generally, used for measuring low frequency signal. When the time/div is 100ms/div or slower, the oscilloscope automatically enters the scan mode.
Vertical System Vertical system can be used to adjust the vertical scale and location and other settings of the channel. Each channel has a separate vertical menu, and each channel can be set separately. 1. Vertical Position Press Channel -> F1 to select the channel, and press Up or Down direction keys to move the vertical position of the selected channel. 2. VOLTS/DIV Settings The range of Volt/div is 10mV/div-10V/div (1X), or 100mV/div-100V/div (10X), 1V/div-1000V/div (100X), step by 1-2-5. Press Channel->F1 to select the channel, and press Right or Left direction keys to change the Volt/div of the selected channel. 3. Channel Setting Menu On/Off On Off Turn on the waveform display.
Turn off the waveform display. DC passes both DC and AC components of the input signal. AC blocks the DC component of the input signal and attenuates signals below 10Hz. GND disconnects the input signal. DC AC GND Coupling 1X 10X 100X 1000X Probe Selects a value according to the probe attenuation factor so as to ensure correct vertical readouts. Reduce bandwidth to 6MHz when using a 1X probe. Limits the bandwidth to reduce display noise; filters the signal to eliminate noise and other unnecessary HF components. BW Limit On Off Invert On Off The invert function turns the displayed waveform 180 degrees, with respect to the ground level.
When the oscilloscope is triggered on the inverted signal, the trigger is also inverted. 13 Options Settings Comments
