Frequency 1 (Hz) - sets the output frequency or the start frequency of a sweep.  The lowest frequency available is 10Hz.  The upper frequency limit will depend on the soundboard.  Frequency can also be set as musical pitch where, for example, 4 is the fourth octave and A is the note.

Sweep - when set the output sweeps between Frequency 1 (Hz) and Frequency 2 (Hz).

Invert - inverts the output waveform.  Really only relevant when generating tonebursts.

Sine - sets the output waveform to a sine wave.

Shortcut - Ctrl+I

Triangle - sets the output waveform to a triangular waveform.  Only available at one tenth of the maximum frequency available, typically 2,000Hz.

Shortcut - Ctrl+G  Selects Triangle and sets (%) to 50.

Shortcut - Ctrl+W  Selects Triangle and sets (%) to zero.

(%) - sets the symmetry of Triangle and Mark/Space waveforms.  Only available when either Triangle or Mark/Space are are selected.  (%) can be set in the range 0-100.

Mark/Space - sets the output waveform to a mark/space waveform.  Only available at one tenth of the maximum frequency available, typically 2,000Hz.

Shortcut - Ctrl+Q  Selects Mark/Space  and sets (%) to 50.

Noise - sets the output to white noise.

Out - the slider sets the output volume.

Mute - when set mutes the output.  (If Sweep is set then when Mute is cleared sweeps run continuously until Mute is selected again.)

Line/Mic - These option buttons select the input line.

Mute - when unset SigJenny acquires and displays the selected input line.
