Signal power setting
Configures RF power.
Received Satellite Power
Specifies the power of one GPS, Galileo, GLONASS, BeiDou, and QZSS satellite.
The power can be changed for every system individually if selected in GNSS simula-
tion.
External Power Attenuation
Specifies external power attenuation.
External attenuator is recommended for levels below -120 dBm for the following rea-
sons:
●
The level uncertainty increases for lower levels
●
The maximum attenuation of the internal step attenuator is -150 dBW. Lower levels
are achieved by reducing the internal amplification. The signal level goes down, but
the noise floor remains at a constant level. Applying an external attenuator instead
decreases the signal level and the noise floor to the same degree, thus maintaining
the dynamic range.
●
The minimum of the level setting range is -200 dBW. Attenuators are the only way
to reach even lower levels
