National Instruments PXI-5600 Downconverter

The National Instruments PXI-5600 (Part Number: 778283-01) is a broadband Downconverter, capable of vector RF estimations in a minimized 3U PXI module. The NI PXI-5600 highlights a wide real-time bandwidth capacity of 20 MHz, an exceptionally stable time base, and great integration with PXI digitizers for RF examination applications. The PXI-5600 gives remarkable frequency attributes over its working scope of 9 kHz to 2.7 GHz. It gives a typical noise density of <-140 dBm/Hz and more than 80 dB of intermodulation spurious-free dynamic range, while the typical phase noise is <-94 dBc/Hz at a 10 kHz offset.

The NI PXI-5600 Downconverter also offers an Ultra-high Stability Timebase. The PXI-5600 offers an amazingly high-security timebase with a frequency stability of ±20 ppb and recurrence exactness of ±50 ppb, making it helpful for a scope of automated applications, where remarkable frequency precision is required.

The noise and distortion qualities of the PXI-5600 are steady and repeatable over an extensive variety of time and temperatures. For instance, at a 1 MHz estimation data transfer capacity, a - 30 dBm input signal regularly has a single, unaveraged, estimation repeatability of under 0.2 dB. The PXI-5600 utilizes a software compensation strategy that lessens amplitude error to under 0.2 dB over a 20 ˚C change.

The PXI-5600 operates using the NI-RFSA 2.1 and/or the NIPXI-5600 Support driver software. Installing the software requires the presence of an Application Development Environment (ADE) such as LabVIEW, LabWindows/CVI, Microsoft C/C++s. Also, additional software such as the modulation toolkit and the Spectral Measurements toolkit are provided by NI. The spectral measurement toolkit is essential to using the RF vector analyzer. The device has 6 connectors: FREQ REF IN, 10 MHz OUT, PXI 10 MHz I/O, OUTPUT, and INPUT connectors. It has a recommended warm-up time of 20 minutes; and should be calibrated at least once a year.

This model offers 20 MHz real-time bandwidth, a High-stability timebase (10 MHz OCXO), ±20 ppb frequency stability, ±50 ppb frequency accuracy, >80 dB spurious-free dynamic range, <-135 dBm/Hz average noise density, and +30 dBm full-scale input range. The device has the dimensions: 3.9 x 6.3 in.
