Describe the signal
Channel count, input level, impedance, coupling and useful frequency range determine the front-end requirements.
MINGDEYANG / ENGLISH PREVIEW
From an analogue signal
to a defined data path.
Plan the input, sampling, FPGA processing and host connection as one system.
DEFINE THE CHAIN
Define the capture
Specify sampling rate, resolution, trigger, synchronization and capture duration.
Plan the host path
Specify interface, operating system, transfer rate, file format and the software functions you need.
Evaluation first.
Adaptation by scope.
The AD9653 and Kintex-7 configuration is a starting point for discussion. Changes to the analogue front end, transfer interface, firmware or host software are assessed against your requirements.
See the evaluation configuration →Make the result measurable
Agree the hardware and software versions, input conditions, capture mode, test duration and acceptance criteria. These details should accompany any performance evidence used for your project.
