Description

I. Product overview
Type: medium frequency digitizer
Main functions: On-board signal processing (OSP), including orthogonal digital down conversion (DDC), real-time digital down conversion and anti-aliasing filtering.
Applications: Very suitable for communication applications, capable of processing high-speed, high-precision IF signals.
Two, the main characteristics
High performance sampling:
With a sampling rate of up to 150 MS/s, high-speed IF signals can be captured in real time.
The resolution reaches 16 bits, providing high precision signal digitization.
High dynamic range front-end:
Equipped with a high dynamic range front end to ensure signal accuracy and stability during digitization.
High throughput interface:
Through the PXI Express interface, NI PXIe-5622 can carry out long-term inventory of IF data streams with high throughput to meet the requirements of long-term monitoring and recording.
Flexible bandwidth configuration:
Support 3 to 250 MHz bandwidth in direct path mode, or 50 MHz bandwidth with a center frequency of 187.5 MHz, to meet the requirements of different application scenarios.
Orthogonal digital Down Conversion (DDC) :
Orthogonal digital downconversion with up to 60 MHz IF bandwidth supports efficient processing and analysis of complex signals.
