• “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.
Setting Up Channels
Each channel has its own separate Menu. The items are set up
separately according to each channel.
1. Setup Channel Coupling
Note：
● The oscilloscope vertical response rolls off slowly above its
bandwidth. 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 noting 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.
