"Auto"
The RF attenuation mode is selected automatically.
The signal attenuation is selected automatically according to the sig-
nal strength.
This mode works best with clean signals. In difficult receiving condi-
tions, the "Low Noise", "Normal" or "Low Distortion" modes can be
more stable.
When monitoring signals with mostly constant signal levels, it is also
recommended that you use the "Low Noise", "Normal" or "Low Distor-
tion" mode.
If the R&S
EVSF1000 has to adapt the attenuation frequently, indica-
ted by a frequent clicking noise from the attenuator, spikes can occur
in the trace.
Remote command:
RF Mode
Defines the RF attenuation mode to be used.
"Low Noise"
15 dB pre-amplification
Provides a high sensitivity. Suitable when scanning the area for dis-
tant signals.
"Norm"
0 dB
Provides a normal sensitivity.
"Low Dist"
15 dB attenuation
Provides a low sensitivity. Suitable when analyzing a nearby signal, to
avoid overload due to high-level signals.
Remote command:
Transducer Correction
Configures the level correction. The specified value is added to the measured power
levels to compensate for an inherent offset by the measurement setup, for example the
antenna.

Setting the Measurement Time (MTime)

: [d]
The measurement time determines the interval at which new measurement results are
displayed. Internally, values are captured every 100
ms, that is: 10 per second. (With
the High Measurement Rate option R&S
