Performance Tests (Agilent N7841A Software Package)
The performance tests section of the Agilent N7841A software package verifies the electrical
performance of your FieldFox 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.agilent.com/find/calibrationsoftware for further information.
There are seventeen performance verification tests that test for the general functionality of the analyzer
and the SA (spectrum analyzer) specific functionality.
Total test time may be up to 3 hours depending upon model and options installed.
Details for these tests and recommended troubleshooting information can be found in the N7841A help
file.
