“1:1”, “1:10”, “1:100” or “1:1000” – probe attenuation ratio
WARNING: Selection of improper probe attenuation ratio may result in
incorrect information about voltages.
Click or to select coupling. Click to ground input.
If the external attenuation is enabled in the options the external attenuation controls
are available in the top of the panel.
Fig. 4.1.12.2. – External attenuation controls
External attenuation controls allow you to measure the voltage on the divider where
the software automatically calculates voltage on the divider input.
WARNING: In case you are using 1:10 probe, don’t use external attenuation
controls to perform transformation. Please always use above mentioned controls
to set the probe attenuation.
Click the button to open the window where you can select the divider attenuation.
