Enter values of resistors and capacitors to set Fc  (See Android Electrodroid APP :) )

Set signal generator frequency.

Use mouse wheel in bode plotter (F in yellow triangle bottom right) mode to adjust dB & phase angle scale

Drag horizontal scale to change frequency.

Drag the dots on the waveform to move the cursor and change the measurements on the graph taskbar.

Enter frequency and values of R & C to confirm where -3dB point is.  Remember that the frequency is a logarithmic scale - not evenly distributed.

Use camera icon to save copy of your circuit in black ON white.  

Use print screen to include Bode plotter / Oscilloscope waveforms.
