Reference
4.4.3.1.3 Ratio Reference
If the Tuned RF Level is to be displayed relative to a reference, enter the value as a ratio reference using this key.
4.4.3.1.4 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.
