Description
The PXIe-5644 is a versatile vector signal transceiver that comes with a variety of specifications designed to meet various testing and measurement needs. This model has been assigned part numbers 782376-01 and 150818E-02L, indicating its unique identification for order and support purposes.
With a bandwidth of 80 MHz, this device is capable of handling a wide range of frequencies, specifically from 65 MHz to 6 GHz. This range ensures that it can be used for a variety of applications, from low-frequency signals to high-frequency wireless communication testing. The initial adjustment accuracy is specified as ±200 × 109, and it has an aging factor of ±1 × 10-6 per year, showcasing its reliability over time.
The amplitude range stretches from the average noise level to an impressive +30 dBm, providing a wide dynamic range for signal generation and analysis. The RF reference level resolution and range are guaranteed to be ≥60 dB in 1 dB nominal steps, which allows for precise control over signal levels. Additionally, the timing resolution of less than 1 Hz ensures high accuracy in timing-sensitive applications.
For connectivity, the PXIe-5644 utilizes an SMA (female) connector with a 50 Ω nominal input impedance, AC coupled, ensuring compatibility with a wide range of RF equipment. The device is designed to be highly compatible with software, supporting NI-RFmx, NI-RFSA, NI-RFSG, LabVIEW, LabVIEW FPGA Module, and LabVIEW Real-Time Module (optional), providing flexibility in application development and integration.
The digital I/O connector type is VHDCI, indicating a high-density cable interface that allows for a compact and efficient connection. The absolute maximum input range for the digital I/O is specified as -0.5 V to 4.5 V, and although the nominal input impedance for the digital I/O is not specified in this document, it is designed to match industry standards for high-performance digital communication.
