The EVM software also provides the option to save all registers to a file or to load registers from a file.

4 Initial EVM Setup and Basic Test Procedure

The fastest way to get the AFE722x EVM up and running is to follow this operating procedure:

• Two signal generators should be connected to the clock and data input of the EVM - preferably with

bandpass filter and 10-MHz reference locked for coherency.

• Clock input should be connected to CDC AUX IN input for AUX clock setup and the clock generator

amplitude should be set to ~10–13 dBm.

• TSW1400 or TSW1405 (RX) capture card should be plugged in to the AFE722x EVM and connected

to the PC via USB.

• TSW1400 or TSW1406 (TX) pattern generation card should be plugged into the AFE722x EVM and

connected to PC via Ethernet cable.

• All appropriate power supplies should be connected – blue LED (D2) on AFE722x EVM indicating

power good status.

• After performing USB reset in AFE722x EVM software, the flashing USB warning sign should

disappear indicating successful USB communication.
