4.3.16 System menu
The System Menu lists the system-related settings of the 4041 series spectrum analyzer. In addition to date and
time, date format, system language, network settings, frequency reference, etc., there are special menus such as
zero frequency calibration and GPS function (option).
The 4041 series spectrum analyzer is featured with zero frequency calibration function, allowing users to perform
zero frequency calibration when needed. When the accurate measurement frequency amplitude of the signal is
lower than 5 MHz, pay attention to the zero frequency signal value. When the zero frequency signal is above -20
dBm, the zero frequency calibration is required to avoid gain compression caused by excessive zero frequency
signal.
The GPS function is an option of the 4041 series. It can be realized through an external GPS antenna. Users can
view the current number of satellites, latitude and longitude, and altitude information.
