Wideband Communications between the RDA and RPG

The Radar Data Acquisition Unit (RDA) and the Radar Product Generator (RPG) are linked by a “wideband” communications line that provides high speed, full duplex (simultaneous, two-way) data transmission. These transmission lines are capable of transmitting the four channels of base data (reflectivity, velocity, spectrum width, and dual-polarization) from the RDA to the RPG.

NOTE: While the dual-polarization channel is available prior to the WSR-88D dual-polarization installation, base data will only be transmitted in this channel after the RDA has been upgraded to dual-polarization.

Depending on the distance between the RDA and RPG (and the locally available services) the wideband link for a particular WSR-88D site may be any one of the following:

• Direct Wire Link,
• Private T1,
• Telco (Commercial) T1, or
• Microwave Line-Of-Sight (MLOS).
