“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.
NOTE:
The oscilloscope’s vertical response rolls off slowly above its
specified bandwidth. Therefore, the FFT spectrum can show valid
frequency information higher than the oscilloscope’s bandwidth.
However, the magnitude information near or above the
