Basic Operation select major or minor window. When the major window is selected, the F1 button provides the same functions as it provides in single-mode window. When the minor window is selected, press TIME/DIV button to scale the waveform whose magnification is up to 1000. 5.2.1 Scan Mode Display (Roll Mode) With the TIME/DIV control set to 80ms/div or slower and the trigger mode set to Auto, the oscilloscope works in the scan acquisition mode. In this mode, the waveform display is updated from left to right without any trigger or horizontal position control.
5.3 Vertical Controls Vertical controls can be used to display and remove waveforms, adjust vertical scale and position, set input parameters and perform math calculations. Each channel has a separate vertical menu to set. See below for menu description. 1. VERTICAL POSITION Bar: Move the channel waveform up and down on the screen. In dual-window mode, move the waveforms in both windows at the same time in a same direction. Two channels correspond to two bars. 2. Menu (CH1, CH2): Display vertical menu options; turn on or off the display of channel waveforms.
DSO1000B(V) Series HandHeld Oscilloscope User Manual 18 Options Settings Comments Coupling DC AC GND 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. Ground disconnects the input signal. 20MHz Bandwidth Limit Unlimited Limited Limits the bandwidth to reduce display noise; filters the signal to eliminate noise and other unnecessary HF components. Volt/Div Coarse Fine Selects the resolution of the VOLTS bar. Coarse defines a 1-2-5 sequence. Fine changes the resolution to small steps between the Coarse settings.
Probe 1X 10X 100X 1000X 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. Invert Off On Inverts the waveform relative to the reference level.
