NI PXIe-5653 Calibration Procedure

Software

Calibrating the NI 5653 requires you to install one of the following packages on the calibration 
system. 

NI-RFSA 2.4 or later

NI-RFSG 1.7 or later

Note

NI-RFSG automatically installs when you install NI-RFSA.

You can download all required software from 

ni.com/downloads

.

The software supports programming the calibration procedures in the LabVIEW, C, and 
LabWindows

/CVI

 application development environments (ADE). When you install the 

software, you need to install support only for the ADE that you intend to use.

Documentation

You might find the following documents helpful as you perform the calibration procedure:

NI 5665 RF Vector Signal Analyzer Getting Started Guide

NI RF Signal Generators Help

NI PXIe-5665 Specifications

The latest versions of these documents are available on 

ni.com/manuals

.

Test Equipment

Table 1 lists the equipment NI recommends for the performance verification and adjustment 
procedures. If the recommended equipment is not available, select a substitute using the 
minimum requirements listed in the table.
