Description
Open a listbox and use the
knob to select the attenua-
tion of the digital selection
(option).
Press 'ENT' to confirm.
Default: 0 dB
If the attenuator in the digital selection is activated, i.e.
the display shows 20 dB, the input signal will be atten-
uated by about 20 dB. This function can be used for
particularly difficult collocation situations to improve
the large-signal behaviour of the receiver.
Navigate to the subdomain Split Site. The first menu is the
Split Site 1/2 menu (see sect. 3.4.3 Menu Split Site 1/2
(3041)).
Start the calibration (see sect. 7.1.1 Synthesizer Calibra-
tion)
Switch the Rx antenna ON
or OFF.
This option is set to ON by default for R&S EK4100
Systems. When set to OFF manually, transmissions
are enabled.
Default: OFF
