Figure 2-7, Figure 2-8, Figure 2-9, and Figure 2-10 show the test setup for LMX2820 phase noise measurement, transmitter performance (SFDR, IMD3) measurement, receiver SNR measurement, and channel-to-channel skew measurement for multiple AFE7950s, respectively.

Use the following steps for each test setup:

1. Connect a 12-V/3-A power supply to the J23 connector of the clocking board.
2. Connect two separate 5-V/4-A power supplies to the J35 connector of both AFE7950EVMs.
3. Connect two separate 5-V/3-A power supplies to the J11 connector of each TSW14J56EVM.
4. Follow the programming sequence in Section 2.1.2 for each board based on the test setup.
