AFE5832 32-Channel Analog Front-End Evaluation Module (EVM Rev. A)

Equipment:

Signal generators (with low-phase noise) must be used as source of the input signal for

optimal performance. An onboard crystal oscillator option is provided so that an external clock source is
not needed for basic capture. Additionally, for best performance a band-pass filter (BPF) is recommended
on the analog input signal to attenuate the harmonics and noise from the signal. For coherent sampling or
custom sample rate, an external clock is provided to J39 or J56 (GUI configuration is required for the
external clock configuration). For more information on clock configuration, see
