National Instruments PXIe-5667 PXI Vector Signal Analyzer

The PXIe-5667 (Part Numbers: 782366-01, 782366-02, 782366-03, 782367-01, 782367-02) is an advanced Vector Signal Analyzer from National Instruments. The instrument comes with the onboard memory to enable various RF measurements. The PXIe-5667 is not a singular physical part- instead, iti refers to the interconnected use of many NI modules. These modules include an RF Downconverter Module (the PXIe-5605), an IF Digitizer Module (the PXIe-5622), a LO Source Module (the PXIe-5653), an RF Preselector Module (the PXIe-5693), and an IF Conditioning Module (the PXIe-5694).

The size of the memory is 64 MB or 256 MB.  The Analyzer provides a frequency range from 20 Hz to 3.6 GHz or 7 GHz. The instrument offers optimized solutions for various testing requirements, such as spectrum monitoring. The PXIe-5667 can be used for the following applications: interference detection, spectrum regulation, and radio monitoring, as well as many applications that involve ITU standards.

The NI PXIe-5667 allows the user to implement sub-octave pre-selection of the bandwidth. The instrument also has a low value for noise figure which is less than 12 dB. The instrument comes with seven built-in IF filters to further enhance the measurement capabilities of the device. Their bandwidth value ranges from 30 kHz to 50 MHz. The hardware modules of the PXIe-5667 Analyzer are interconnected through coaxial cables. Their connectors are the SMA type.

The PXIe-5667 Vector Signal Analyzer strictly follows the industry standards, enabling the user to integrate it with ease for measurement applications. The value for the average noise level of the instrument is -161 dBm per hertz for the frequency range from 87 MHz to 1.5 GHz. The instrument offers an instantaneous bandwidth value of 25 MHz. The device also has the capability to offer the third order intercept of +21 dBm.
