This section describes how to properly set up the connections on the EVM
6.1 EVM Connections
1. If you haven’t done so, connect the USB cable from the MSP430 Launch Pad to your PC.
2. If you haven't done so, connect the TDC7200EVM to the MSP430 Launch Pad via J1 and J2 as shown
in Figure 6 .
3. Setting the Dual Channel Function Generator (for example: Tektronix’s AFG3102):
(a) Set channel 1 of the dual function generator to as follows (see Figure 5 ):
(i) Pulse 1-Cycle
(ii) Burst mode
(iii) Freq = 40kHz
(iv) Delay = 0s
(v) Amplitude = 3.3Vpp
(vi) Offset = 1.65V
(vii) Duty = 20%
(b) Set channel 2 of the dual function generator to as follows (see Figure 5 ):
(i) Pulse 1-Cycle
(ii) Burst mode
(iii) Freq = 40 kHz
(iv) Delay = 19us --> this is the time-of-flight (TOF)
(v) Amplitude = 3.3 Vpp
(vi) Offset = 1.65 V
(vii) Duty = 20%
