Numeric entry for Reference Value. The Reference Value entry button is only visible if Reference Type is set to Reference Value. Select displays the Reference Value field toolbar and allows entry of values in Units. Depending on instrument settings, allows entry of a value in dB (shown below), dBm, Degrees, Henrys (H), Farads (F), or Units.

Searching From
Toggles between Maximum and Beginning. Searching From is only visible if Reference Type is set to Reference Value. Note that if there is only one bandwidth present in the entire sweep, the SearchingFrom field is irrelevant since both should give same result. However, if there are multiple bandwidths, then the beginning will find the first bandwidth.
Searching From → Maximum: If Maximum is selected, the algorithm will first search for the maximum value and start searching left and right for the target value from the position of the maximum value.
Searching from → Beginning: If Beginning is selected, the algorithm will search for the target value from the starting point (i.e. point 0 is search range off or search range starting position).
Note: The above settings are per-marker so there can be 12 different configurations that the user can set. Also, as the display readout is tied to the marker, the functionality does need the marker to be turned on but the calculation and searching is irrelevant to the marker.

Example Reference Value (dB) Field Toolbar.
Searching From
Toggles between Minimum and Beginning. This field is only visible if Reference Type is set to Reference Value. Note that if there is only one notch present in the entire sweep, the SearchingFrom field is irrelevant since both should give same result.
