The purpose of this lab was to familiarize students with analog oscilloscope and hardware for circuit design The lab has two parts the first part is to generate waves using a bit file given in the lab Our task is to learn how to calibrate and adjust the oscilloscope so we can read clearly what our hardware has generated The second part of the lab allows us to create a simple schematic using the Xilinx ISE Project navigator for we are going to be using the BASYS2 board extensively for the remaining of the quarter Part One OscilloscopeBefore we start measuring any waves using the oscilloscope it is important for us to calibrate the scope in order to have crisp readings When I probed the calibrated outputs the square waves displayed on the phosphorus screen were quite fuzzy At the base of the probes for CH1 and CH2 I turned the flathead screws counterclockwise to make the signal clear and readable After calibration we use the Adept software to program a bit file into the BASYS2 board It is given in our lab handout that signals of the bit file provided ce100bit outputs signal to JB-1 and JB-4 connector of the board To read the signals off these connectors we obtained 3 pins 2 of the pins go into the connectors we are reading the signals from and 1 pin goes into ground on the JC connector 5th pin We then connect the oscilloscope to each outputting pin and each probe has an alligator clip that connects to the same ground Immediately we noticed that the two signals have very different frequencies Figure 1We noticed that on the oscilloscope screen although calibrated the waves have fuzzy edges The professor noted that this may be caused by the clock pulses of the processor Also looking at wave from JB-4 there are noticeable bumps between wave propagations it is unclear that whether or not this
