4.4.14.1.4 Ratio Mode
The ratio and previous ratio functions permit any measurement result to be scaled to a reference. The reference
may be either a measurement result or a keyboard entry.
The Log/Linear key enables measurement results to be displayed in linear or logarithmic units, both absolute and
relative. Examples of absolute units are kHz and mV (linear), or dBm (logarithmic). Examples of relative units
are % and dB. When the instrument displays dB as a relative unit, the "REL" indicator is shown on the display.

4.4.14.2.1 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.
