A&D Board User Manual and Test Procedure

24. [ ] While watching the TDS210 CH1 Pk-Pk display, adjust the A&D AMPLITUDE knob to obtain

approximately 1V Pk-Pk (Hint: adjust TDS210 CH1 VOLTS/DIV as needed). While watching the TDS210

CH1 Freq display, adjust the FREQ knob to obtain a 1 kHz square wave (Hint: adjust TDS210 SEC/DIV as

needed). See Figure 16.

25. [ ] Set the A&D SHAPE toggle to “SIN” for Sine Wave output.

26. [ ] Use the A&D AMPLITUDE knob and FREQ knob to obtain a 1 kHz sine wave at 1V Pk-Pk. Did you

need to adjust the A&D FREQ knob? See Figure 17.

27. [ ] Disconnect the mini-grabbers from the A&D board and turn off the oscilloscope. Return the scope

probe to the wall rack in the CEL. Remove the 10k

Ω resistor from the A&D board.
