NI PXIe-5645R

The PXIe-5645, previously known as the PXIe-5645R.

The PXIe‑5645 combines a vector signal generator and vector signal analyzer with FPGA-based real-time signal processing and control into a single device, also known as a VST. Because of this software-designed approach, the PXIe‑5645 offers the flexibility of a software defined radio architecture with RF instrument class performance.

The PXIe‑5645 features a high-performance, differential or single-ended baseband I/Q interface. This interface allows the PXIe‑5645 to address many additional applications, such as testing both the upconverted RF and downconverted baseband signals of a device with a single instrument.

The NI PXIe-5644R/5645R/5646R are comprised of a vector signal generator, vector signal analyzer, and digital I/O, the NI PXIe-5644R/5645R/5646R RF vector signal transceivers (VSTs) combine multiple instruments into a single PXI Express module. Backed by software to support the latest RF standards, including 802.11ac and LTE Advanced, NI vector signal transceivers boast the performance and flexibility of an R&D-grade box instrument with the speed, low cost, and small form factor of a manufacturing test system. In addition, NI vector signal transceivers have a user programmable FPGA at their core, making them software-designed instruments. This allows users to customize the firmware of their instrument down to the pin.

Note:

NI vector signal transceivers feature a zero-IF receiver; allowing it to have higher potential bandwidths, lower cost, less power consumption, and a smaller footprint when compared to heterodyne receivers. Other advantages include simpler designs with single LOs, and high selectivity, which allows separation of adjacent channels whose signals overlap.

Note:

The NI vector signal transceiver RF transmitter uses direct RF up conversion from differential baseband I/Q, which up converts the baseband signal from DC to RF at the configured LO frequency.
