National Instruments PXIe-5665 PXI Vector Signal Analyzer
The PXIe-5665 (Part Numbers: 781426-01, 781426-02, 781426-03, 781428-03, 781774-01, 781428-04, 781775-01, 781774-02, 781775-02, 781995-01, 781996-01, 781774-03, 781775-03, 781995-02, 781996-02) is a high-performance Vector Signal Analyzer from National Instruments. There is no one physical device called the PXIe-5665- instead, the model name refers to the interconnected use of the PXIe-5622 IF Digitizer. PXIe-5603 (or the PXIe-5605) RF Signal Downconverter. and the PXIe-5653 RF Analog Signal Generator from NI.
This Analyzer has varying bandwidths, onboard memory sizes, frequency ranges, and channel counts, as well as a preamplifier available for several of the part numbers. The NI PXIe-5665 frequency measurement bandwidth ranges from 20 hertz to 14 GHz. The typical value of resolution bandwidth offered by the device is 3 dB. The PXIe-5665 also includes a reference for internal frequency, which is 10 megahertz.
The PXIe-5665 modular Vector Signal Analyzer incorporates three-stage superheterodyne technology for analysis. The instrument has the capability to operate in RF list mode. The Analyzer also incorporates various tools for customization of the equipment settings. It allows the users to make use of different modulation schemes. This enables a low-cost solution for various industrial requirements. The NI PXIe-5665 also offers a wide range of measurement applications, which enables the users to perform critical measurements with high accuracy. The measurements included are for GSM, EDGE, WCDMA, Bluetooth and other communication standards.
The PXI-5665 Vector Signal Analyzer has a noise value of -165 dBm/Hz between 300 MHz and 1.7 GHz. The instrument also offers an onboard memory for various RF analysis requirements. The size of the memory is 256 MB maximum. It also offers one or two input channels. The nominal value for the input impedance of the device is 50 ohms.
The PXI-5665 is Obsolete and no longer available from National Instruments (NI), but the Vector Signal Analyzer will remain available in perpetuity with Apex Waves!

National Instruments PXIe-5665 Frequently Asked Questions
Question: What parts comprise the PXIe-5665?
Answer: There is not a singular physical device named the PXIe-5665; instead, the PXIe-5665 is comprised of several models. The PXIe-5665 3.6 GHz VSA is comprised of the PXIe-5653 Analog Signal Generator, the PXIe-5622 IF Digitizer, and the PXIe-5603 RF Signal Downconverter. However, the PXIe-5665 14 GHz VSA is comprised of the PXIe-5653 Analog Signal Generator, the PXIe-5622 IF Digitizer, and the PXIe-5605 RF Signal Downconverter.
Question: Under which circumstances should the NI PXIe-5665 be self-calibrated?
Answer: The NI PXIe-5665 should be self-calibrated when it is initially installed and connected, when there is a physical modification to one of the system parts, when there is a different type of system cabling added, when the system is in a setting where external factors like temperature could impact the measurements, or when the module exceeds a temperature or time limit.
Question: What is the tuning resolution of the PXIe-5665?
Answer: 533 nHz is the tuning resolution of the PXIe-5665.
