ABSTRACT:
Apparatuses for a test and measurement instrument provide an instrument capable of handling acquisition, transfer, analysis, and display of large quantities of waveform data and complex waveforms. The apparatus for a test and measurement instrument consists of multiple processors with each processor being connected to its own memory controller. Each memory controller is connected to its own memory. The processors are connected in a circular arrangement by multiple high-speed interconnects. A bridge is connected to at least the first and last processors. A system bus connects the bridge to an acquisition module. The acquisition module has a signal bus interface with the system bus being connected to the acquisition module and having its own acquisition hardware. The acquisition hardware is a direct memory access machine that can transfer data to any portion of the memory. There is a signal source connected to the signal bus interface.
