Settings softkey
The (settings) softkey opens the measurement dialog for setting additional basic
measurement parameters.
Configuration preset softkeys
The (preset configuration) softkeys recall previously assigned measurement con-
figurations, defined for dedicated measurements. You can assign up to three predefina-
ble configuration presets.
How to: see Section 8.7.2, "Using the configuration preset function", on page 92
Signal parameters
