Install the oscilloscpe interface program elab_01_08_00.exe. This program will allow you to view the oscilloscope trace files. The oscilloscope trace archive traces.zip contains the test data from the trial runs performed in Physics class. The drop height for all the trials is 58cm. One low-going pulse is generated every time the wheel completes one rotation. One rotation is 11.6cm. Five pulses is 58cm.
Start the elab-080 program under the Dynon Instruments folder. The program will pop up a message indicating that an oscilloscope could not be detected. The The program will work regardless of weather the scope is connected or not, the only difference is that the oscilloscope interface controls will not work. Click file -> import dso/la data. Select the .dla trace file for a trial run. On the dso tab, shift the ground offset with the large blue arrows so the ground reference (GND on the left side of the oscilloscope window) is as low as it will go. Then scale toward V (smaller) or mV (bigger) until the trace is as large as it will get before going off the screen. S zooms out and mS zooms in (seconds and milliseconds). Set timing cursors on the oscilloscope window (right click -> set timing cursor) to determine the delay between pulses. Important: always measure the RISING edge of the pulse (transisition from low to high) for precise results. If both timing cursors are set, the lower number in the parentheses is the difference in time between the two cursors. ms = 1/1,000 second and us = 1/1,000,000 second.
