1.5 Connection to the DAQ device
The DAQ device must be properly connected to the circuit in order to
sense the voltage. Figure 1- 6 shows the screw terminal block where
you will need to connect the wires. The screw terminal block is
connected to Agilent USB DAQ with a SCSI cable. Both the signal and
ground needs to be connected, as voltages are “relative”
measurements. Pin 1 is the analog input channel 1 (called channel
101 in the program), and pin 39 is the analog ground. Wire pin 39
with a black or blue wire to your ground strip on the protoboard, and
wire pin 1 with a yellow or white wire to your signal.
