3 Operating Modes
3.1 Scalar Chart Mode
In the Scalar Chart mode, a user-selectable parameter is plotted over the user-specified
frequency range.
One adjustable marker can be used to display the frequency and value at the marker position.
The marker position can either be user-selected or automatically tracked. See section 2.6.
The measurements can be stored at any time on the internal disk by using the save file
operation. See section 2.8.
The Run/Hold [ ] button controls the run status. The measurements can be stopped at any time
by pressing the Run/Hold [ ] button and resuming them by pressing this button again.
