Complete the following for bode loop testing:

1. Cut the connection from R15 to TP3 (24 V). This cut is bridged with 49.9 Ω and is called R100.
2. On the PCB, cut the TP8 connection to U2–13. R10 (power good pullup) is not populated.
3. Populate TP8 with a green through-hole test point (Keystone 5116) and tie to a connection between R100 and R115. TP8 becomes a signal injection point for the bode plot.
4. Use a network analyzer such as the Bode 100 from Omricon Lab with the following:
   • V1 measured between injection point TP8 and ground TP10
   • V2 measured between V_OUT TP3 and ground
   • Actual signal injection between TP8 and TP3
