■

“GND” Coupling: Use GND coupling to display a zero-volt waveform.

Internally, the channel input is connected to a zero-volt reference level.

■

Fine Resolution：The vertical scale readout displays the actual Volts/Div

setting while in the fine resolution setting. Changing the setting to coarse does

not change the vertical scale until the VOLTS/DIV control is adjusted.

■

Wave Cancel：Press the menu button for the channel to display its vertical

menu. Push the menu button again to remove the waveform.

Note：● The oscilloscope vertical response rolls off slowly above its bandwidth ,

which depending on the model, or 20 MHz when the Bandwidth Limit

option is set to “On”. Therefore, the FFT spectrum can show valid

frequency information higher than the oscilloscope bandwidth. However,

the magnitude information near or above the bandwidth will not be

accurate.

● If the channel is set to DC coupling，you can quickly measure the DC

component of the signal by simply nothing its distance from the ground

symbol.

● If the channel is set to AC coupling，the DC component of the signal is

blocked allowing you to use greater sensitivity to display the AC

component of the signal.
