Diode testing is very simple. put your digital multimeter in continuity/diode test range. In forward bias it will show some reading in range of 200 to 600 and in revese bias it will show opwn (i.e. 1 digit will be displayed on left most side of meter). if it is open in both side or buzzer sounds it is bad. to measure frequency you can use oscilloscope of frequency counter.
