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 information

Press 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 information

Selects 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 information

Press this softkey and turn the V0 knob to set a proper attenuation factor to match your connected probe.

Channel Key -> Invert Softkey help information

The Invert softkey changes the orientation of the displayed waveform's voltage.

Channel Key -> Units Softkey help information

Press this softkey to select the measurement units V (Volts) if connect a voltage probe, and select A (Amps)

if connected a current probe.

WisdomAugust

Channel Key -> Deskew Softkey help information

Press 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 information

Sets the waveform display to expand or compress about the center screen or channel's ground when

you adjust the volt/div setting.

WisdomAugust

Channel Key -> Label Softkey help information

Press this softkey to enter the Label Menu.

Channel Key -> Label -> Display Softkey help information

This softkey enables or disables the display of the channel label.

Channel Key -> Label -> Preset Softkey help information

Select the preset label from CH1, CH2, CH3, CH4, CLK, DATA, CS, MISO, MOSI, RX, TX, IN, and OUT.

Channel Key -> Label -> Edit Softkey help information

Press 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 information

Press this softkey to return to the previous menu.

WisdomAugust

Channel Key -> Impedance Softkey help information

The default input impedance of the oscilloscope channel is 1MΩ.

Math Key help information

You can press the Math key to access the add (+), subtract ( - ), multiply ( * ), divide ( / ), FFT

( Fast Fourier Transform), integral ( ∫dt ), differential ( d/dt ), square root ( √￣ ), and expression functions.

WisdomAugust

Math Key -> Operator Softkey help information

Press this softkey to select your desired math function.

Mathematical Operations

+ - Adds the waveform voltage values of source 1 and source 2 point by point and displays the result.

-  - Subtracts the waveform voltage value of source 1 from the waveform voltage value of source 2 point by

point and displays the result.

* - Multiplies the waveform voltage value of source 1 by the waveform voltage value of source 2 point by

point and displays the result.

/ - Divides the waveform voltage value of source 1 by the waveform voltage value of source 2 point by

point and displays the result.

WisdomAugust

Transforms

FFT - Converts a time-domain waveform acquisition to frequency domain components.

Function Operations

∫dt -  Calculates the integral of the selected source.

d/dt - Calculates the discrete time derivative of the selected source.

√￣ - Calculates the square root of the selected source.

Expression - Lets you create custom math waveform expressions that incorporate active and reference

waveforms, measurements and numeric constants.

WisdomAugust

Math Key -> Operator -> +, -, *, / -> Source 1 Softkey help information

Source 1 selects the channel for the first term of math function.

Math Key -> Operator -> +, -, *, / -> Source 2 Softkey help information

Source 2 selects the channel for the second term of math function.

Math Key -> Operator -> ∫dt, d/dt, √￣ -> Source 1 Softkey help information

Source 1 softkey selects the channel for the source.

Math Key -> Operator -> ∫dt -> Settings Softkey help information
