Performance Tests (Keysight N7841A Software Package)

Performance Tests (Keysight N7841A Software Package)
The performance tests section of the Keysight N7841A software package verifies the electrical performance
of your N9912A analyzer. The software automatically configures your analyzer to execute the performance
tests.
The N7841A software package is not included with the analyzer; it must be ordered separately. It can be
downloaded from the Internet and a license purchased on-line, or it can be ordered on a CD-ROM. Go to
www.keysight.com/find/calibrationsoftware for further information.
There are:
• Four tests for the general functionality of the analyzer.
• Seven additional tests for the SA (spectrum analyzer) functions.
Total test time will vary from 7 to 36 minutes depending upon options installed.
