If your graph seems to go horizontal during the run - i.e. it follows the right sinusoid up to a point, and then just becomes a constant - check in the MATLAB command window to see if there is an error about the sampling rate.  If there is, go into the DAQrunner.m program and change the sampling rate from 5000 to 1000.

Through Section 6.3.3

Wide view of PBB 272 with LM 324 attached.
Closeup of the LM 342 with buffer wiring on the right and and OpAmp 1 copy wiring on the left.

This part involves wiring the three operational amplifiers used for this experiment. Note that amplifier "2" - which is on the bottom right of the chip in the pictures - is not used for this lab.

Through Section 6.3.4

CB-68LP connections showing four analog input measurements (green/black pairs), two analog outputs (red), and both AI and AO grounds.
Right side of Blue Row showing ground and ACH reference wires.
Closeup of breadboard showing four dark green measurement lines and two red DACOUT lines from CB-68LP.

This part involves wiring the measurement lines from the DAQ card through the CB-68LP to the PBB 272.
