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.

Method and system for distributed baseband measurements

Power levels for a code-division multiple access (CDMA) signal with layered orthogonal codes are displayed. When displaying power levels for multiple code layers, a power level for each active code channel is displayed using a bar. A width of the bar indicates in which code layer each active code channel is active. A color of the bar also can be used to indicate in which code layer each active code channel is active. For example, a power level for each active code channel is displayed using a hollow bar and a power level for each inactive code channel is displayed using a line. Alternatively, a power level for each inactive code channel is displayed using a hollow bar and power level for each active code channel is displayed using a solid bar. When displaying a power level for a single code layer, a power level for each active code channel in the single code layer is displayed using a hollow bar, and a power level for each code channel which is inactive in the single code layer is displayed using a line. Alternatively, when displaying a power level for a single code layer, a power level for each active code channel in the single code layer is displayed using a solid bar, and a power level for each code channel which is inactive in the single code layer is displayed using a hollow bar.
