GETTING STARTED GUIDE
PXIe-5668
Up to 26.5 GHz PXI Vector Signal Analyzer
Note
Before you begin, install and configure your chassis and controller.
This document explains how to install, configure, and test the PXIe-5668. The PXIe-5668 is a
26.5 GHz or 14 GHz modular vector signal analyzer (VSA). The PXIe-5668 ships with the
NI-RFSA instrument driver, which you use to program the device. You can also use NI-RFmx,
available at ni.com/downloads, to program the device.
The PXIe-5668 comprises the following devices:
•
PXIe-5606 RF Signal Downconverter (PXIe-5606) RF downconverter
•
PXIe-5624 IF Digitizer (PXIe-5624) intermediate frequency (IF) digitizer
•
PXIe-5653 RF Analog Signal Generator (PXIe-5653) synthesizer/local oscillator (LO)
source module
In this document, PXIe-5668 refers to both the PXIe-5668 26.5 GHz VSA and the PXIe-5668
14 GHz VSA unless otherwise specified.
