13. [ ] Turn the TDS210 SEC/DIV knob clockwise to indicate 10us/division.

14. [ ] Gradually turn the A&D FINE FRQ (5 kHz to 20 kHz) knob clockwise and verify that the frequency

increases up to approximately 20 kHz at 10V Pk-Pk as shown in Figure 12.

15. [ ] Keeping the A&D AMPLITUDE knob turned fully clockwise, set the A&D OFFSET SW to “ON”.

16. [ ] Gradually rotate the A&D OFFSET knob in both directions. Notice that the waveform becomes flat on

the top or bottom, as the function generator output approaches the power supply limits. The OFFSET

control can be used to compensate for component variations.

17. [ ] Set the A&D OFFSET SW to “OFF”.

18. [ ] Set the A&D SHAPE toggle to “SQ” for Square Wave output.

19. [ ] Verify that the output is a square wave of approximately 20 kHz at approximately 13V Pk-Pk as shown

in Figure 13.

20. [ ] Turn the TDS210 SEC/DIV knob counter-clockwise to indicate 50us/division.
