The Zebra Controller is the PC interface that enables a user of the Zebra CDMA source to control and configure the unit for desired performance. The Zebra Controller is designed to allow the user to quickly create or load a waveform and send it to the Zebra through a serial connection for transmission. Zebra Controller allows the user to load either pre-defined or custom waveform parameters into the Zebra for transmission at the appropriate time. Zebra Controller also allows the user to mark a specific waveform as the default. This allows the Zebra to operate individually without the PC by transmitting the waveform that has been marked as default. Parameters for waveforms can be created in Zebra Controller and then saved to disk for use at a later time. These saved waveforms can then be read back into the application software for loading and playing on the Zebra.

Zebra Controller also allows the user to select a clock source. The Zebra can use its internal clock or either one of two distinct external clock sources. The Zebra controls allow the user to read and send parameter information to and from the Zebra, create data for the current bank for transmission, as well as start and stop transmission. Power for Pilot, Sync, and Paging channels can be manually selected. Any remaining power will be distributed among the active traffic channels.

Another feature of the Zebra Controller is its ability to activate multiple carriers. Each waveform may have different carrier setups. The level of each of the carriers is between 0 and -40 dBm. If the particular carrier is active, it will show up as a solid green rectangle on the display. If the carrier is not active, it will show up as a hollow rectanglewith a dashed outline.

What is the difference between the Rhino and Zebra products?
Rhino is a portable frequency source while Zebra is a wideband CDMA source designed specifically for the laboratory.
