Operating the spectrum diagram

Instead of using the buttons to adapt the diagram to your needs (e.g. Fcent to set the center frequency), touch functions allow a quicker and more convenient operation.

For information about the button functions see here.

Selecting the center frequency

The center frequency is marked by a dashed line in the middle of the diagram.

To center a frequency tab on the frequency scale below the X-axis and drag the wanted frequency to the center line.

Zooming the frequency span

To zoom in:

Tap inside the diagram and drag to the right.

The dragged range is highlighted in grey.

When releasing the touchscreen, the frequency range is zoomed to the highlighted range.

 

To zoom out:

Tap inside the diagram and swipe to the left.

With each swipe the frequency span is doubled.

Fitting in the level automatically

Tap on the icon in the lower left corner of the window.

The level range of the measured spectrum is fitted to the diagram.
(This is identical to Auto Range in the Config menu but allows a much faster operation).
