TEST AFE5808/08A

8.2 Step 2: Single Tone FFT

• Select the Single Tone FFT page at the TSW1250 GUI.

• Connect Channel 1 of the AFE5808/08AEVM to a signal generator through an LP filter. If an LP filter

is not present, the result will not be good.

• Set the amplitude of the signal generator to -25dBm.

• Set the frequency of the signal generator to 2.00439453M to match the GUI.

• Change the window option to Hanning. This is because the input signal and the onboard CMOS clock

are noncoherent.

• Press the Capture button to get the test result.

• Repeat for Channel 2 through Channel 8.
