Using the Oscilloscope
The Scope Channel Menu
Probe field
You use the Probe field to set the probe attenuation factor for the input
channel currently displayed in the Input field.
Probe attenuation factor
The probe attenuation factor can be set from 1:1 to 1000:1 in
increments of one. When you select a probe attenuation factor, the
actual sensitivity at the input does not change. The voltage values
shown on the display (V/div, offset, trigger level) are automatically
adjusted to reflect the attenuation factor. The marker and automatic
measurement voltage values change when a Run is initiated and the
next acquisition is displayed.
Coupling field
You use the Coupling field to set the input impedance for the channel
currently displayed in the Input field.
Coupling field selections
When you select the Coupling field, a pop-up appears that shows the
input impedance values available. The selectable values are 1MW / DC,
1MW / AC, and 50W / DC.
CAUTION:
The maximum input voltage for the 50W / DC Coupling field selection is 5
Vrms.
