IsClockwise [Antenna]

Value Type: Boolean.

Range/Units: 0 (CCW) or 1 (CW).

Default Value: 1.

Change Dynamically? Yes (use RDACS Config Configuration

Antenna

command).

This variable sets the default antenna direction when the antenna scan mode is PPI.

6.6 LevelN Section

This section is repeated multiple times (for example, Level0, Level1...Leveln). Each

instance is a conversion table that translates engineering units to display, or color,

levels. There are three types of products emanating from the RVP7: (1) R - reflectivity,

(2) V - velocity, and (3) W - spectrum width. At least three Level table sections should be

created, one for each product table. In practice, additional tables can be created with

different thresholds to better match the range of values encountered in a particular

mode. For example, if two different modes acquire velocities at different PRFs, the range

of unambiguous velocities will be different and it may be desirable to map these into

different display levels.

For a given mode, which is specified in the ModeM section, the desired LevelN section

is selected by the RLevel, VLevel, and WLevel variables. For example, if in Mode3 and

VLevel=2, the threshold values in Level2 are used for velocities in Mode3.

The total number of level tables is recorded in the NumLevels variable in the

Master section. If you add or remove a section, be sure to update

NumLevels.
