4.4.3.2 Meas Setup
Displays the measurement setup menu for the TRFL Measurement when the TRFL
Measurement key has been
selected in the
Measure menu.
4.4.3.2.1 Accuracy
This parameter is used to set average accuracy mode which can take effect on the actual average time used in this
measurement. There are two modes that can be selected by user, they are Normal accuracy and High accuracy.
The two modes can be explained as follows,
• Normal accuracy mode is the default state of this parameter. In this setting, the standard deviation of
uncertainty of measurement level is set to 0.027 when SNR>30dB or 0.1 when SNR<30dB.
• High accuracy mode will set the standard deviation of uncertainty of measurement level as 0.027 when
SNR>30dB or SNR<30dB.
4.4.3.2.2 IF BW
This parameter allows you to set IF BW. The following options can be selected:
10 Hz (default) Use this setting to measure lower signal levels, but it cannot tolerate poor residual FM noise
from the source.
75 Hz This setting tolerates measuring poor residual FM noise better and can measure a signal level
8.75 dB higher than the 10 Hz setting.
30 kHz Use this setting for measuring drifty sources.
200 kHz Use this setting for measuring drifty sources.
