NI 5600 RF Downconverter Module Block Diagram
The NI 5600 RF downconverter module translates any 20 MHz-wide band of incoming signal to center at 15 MHz. Thus the downconverter module converts any block of spectrum, up to 20 MHz wide and centered anywhere between 9 kHz and 2.7 GHz, to an IF band between 5–25 MHz. The NI 5600 hardware always downconverts a 20 MHz band. This IF band is then passed to the NI 5142 digitizer module for further processing.
The following figure shows the NI 5600 block diagram.
