Abstract
A baseband measurement system includes a host and a Digital Immediate Frequency (DIF) subsystem. The DIF subsystem includes both hardware and software components, such as, for example, a microprocessor and its associated software, a FPGA, one or more ASICs, and memory. The baseband measurements are processed using the FPGA, ASICs, and the microprocessor and its software. The microprocessor controls the flow of the data in and out of the memory and distributes the processing tasks to both the hardware and software components in a cooperative manner. The microprocessor orchestrates the measurements and processing by operating as a measurement state machine. Selection of the proper component is based on the type of measurement and its processing requirements, as well as the current state of the hardware and software components. The host receives the processed data and performs post-processing operations if needed. The host also displays the processed data.
