Reference
Each of the data screens always displays a reference info bar across the top.
This bar always shows tiles displaying the reference phase, frequency, detected harmonic,
sine out amplitude and dc level. Each of these parameters can be adjusted using the knobs
and buttons in this section of the front panel.
Touching one of these tiles brings up a numeric keypad for direct entry.
