Channel Key -> Coupling Softkey help information
Sets the channel's input coupling to DC, AC, or GND to suit your measurement needs.
* DC (direct current) - Displays the whole input signal including constant positive or negative voltages.* AC ( alternating current) - Blocks the steady voltage and displays small variations.* GND (ground) - Sets the display to 0V before you do any measurement.
Channel Key -> BW Limit Softkey help informationPress this softkey to enable or disable the bandwidth limit for the selected channel. When you turn on the Bandwidth Limit 20M, the channel's maximum bandwidth is set to 20MHz to eliminate noise and unwanted high-frequency content.
Channel Key -> Adjust Softkey help informationSelects Fine or Coarse adjustment for the volt/div knob.* Fine (variable) - Adjusts the channel sensitivity in small increments.* Coarse (fixed) - Sets the channel sensitivity in a 1-2-5 step sequence.
Channel Key -> Probe Softkey help informationPress this softkey and turn the V0 knob to set a proper attenuation factor to match your connected probe.
Channel Key -> Invert Softkey help informationThe Invert softkey changes the orientation of the displayed waveform's voltage.
Channel Key -> Units Softkey help informationPress this softkey to select the measurement units V (Volts) if connect a voltage probe, and select A (Amps) if connected a current probe.
Channel Key -> Deskew Softkey help informationPress this softkey and turn the V0 knob to set the desired deskew time between analog channels. Setting range: -100 ns to 100 ns.For nanoseconds range measurement, even a small transmission delay of the probe cable may bring measurement errors. The Deskew lets you calibrate the probe cable-delay of the corresponding channels.
Channel Key -> Expand Softkey help informationSets the waveform display to expand or compress about the center screen or channel's ground when you adjust the volt/div setting.
Channel Key -> Label Softkey help informationPress this softkey to enter the Label Menu.
Channel Key -> Label -> Display Softkey help informationThis softkey enables or disables the display of the channel label.
Channel Key -> Label -> Preset Softkey help informationSelect the preset label from CH1, CH2, CH3, CH4, CLK, DATA, CS, MISO, MOSI, RX, TX, IN, and OUT.
Channel Key -> Label -> Edit Softkey help informationPress this softkey to display the Label Edit Virtual Keypad on the screen. Then, use the V0 knob or touch gestures (if touch screen enabled) to edit your waveform label and press Enter key on the keypad to create a new channel label.
Channel Key -> Label -> Return Softkey help informationPress this softkey to return to the previous menu.
Channel Key -> Impedance Softkey help informationThe default input impedance of the oscilloscope channel is 1MΩ.
