INTRODUCTION
The EVAL-AD8332/AD9238 and ADC evaluation board is a
fully integrated dual-channel differential variable gain amplifier
(VGA) and analog-to-digital converter (ADC) on a single
board. When connected to a multipurpose HSC FIFO board
and operated with the accompanying software, ADC Analyzer™,
it can convert and display analog waveforms processed by the
VGA or perform FFTs and display up to six harmonics. It can
be operated with its onboard clock or from an external clock for
coherent sampling. Figure 2 is a simplified functional block
diagram of the system.
Space is provided for a differential filter (with up to four poles)
between VGA and ADC.

Figure display of an FFT performed on both channels of the AD8332 using the same 1 MHz input signal that is used for the 1 MHz waveforms. A splitter must be used if both LNA channels are driven. Figure 12 and Figure 13 are individual channel FFTs, a useful tool to observe channel isolation ...
