National Instruments NI-5793 RF Adapter Module for FlexRIO

The NI-5793 (Part Number: 782512-01) is a 200 MHz Bandwidth, 200 MHz to 4.4 GHz frequency range, RF Adapter Module for FlexRIO. This module is outstanding, given its size. The RX dynamic range is more prominent than 105 dB, with a noise figure under 8 dB at 2 GHz. The LO phase noise of this model is superior to 94 dBc/Hz at 2.4 GHz and at 10 kHz balance, while the loopback error vector size (EVM) is under 1.5 percent. All details are regular and some require FPGA-based redress calculations, which are given as illustration code.

The NI-5793 FlexRIO RF Adapter Module and the PXI platform offer a way to ADC and DAC information synchronization, which is vital for channel extension. Twelve bidirectional computerized I/O lines steered from the FPGA to a connector on the connector module empower advanced device under test (DUT) control and straightforward advanced conventions. When users share triggers between various gadgets, proliferation delays on the signal way makes the trigger land at various circumstances on every gadget. The synchronization library utilizes the CPTR to back off the trigger assessment rate. All gadgets must create a CPTR signal that is equivalent in frequency and phase adjusted.

With the NI-5793, once the CPTRs are adjusted, users can synchronize an edge over different FPGAs. The master gadget distributes the signal over an FPGA I/O line. All gadgets screen the same FPGA I/O line. The edge is synchronized at the following CPTR edge. After all the gadget CPTRs are adjusted, an edge felt on the FPGA I/O lines is checked at a similar clock cycle over every one of the gadgets.
