* “E/F M40X” or “E/F USER” is displayed in MEAS area on the screen.
* “USER” is the original compensation data which is created by the user.
(Refer to “25.8 Writing of Original Compensation Data” for the details.)
* The spectrum may exceed the area on the screen depending on the antenna gain compensation.
The unit of amplitude axis automatically changes into [d Bμ V/m].
* The optimum center frequency and frequency span are automatically set according to the antenna.
In addition, a spectrum other than the frequency range of the antenna is not displayed.

* The following are the data when the antenna is connected to RF input directly with no obstacles around.
Actually, the directivity changes due to the human body when handling the unit.
* However, the data of M405 is the reference data which is included the influence of the human body.
