Title:
測定機器及び混合信号取込みシステム
Document Type and Number:
Japanese Patent JP5603171
Kind Code:
B2
Abstract:
A mixed signal acquisition system for a test and measurement instrument allows configuring of the number of analog and digital channels in use. The instrument includes an analog input interface and an N-channel logic input interface for receiving an analog signal and an N-channel logic signal, respectively. An A/D converter converts the analog input signal into an N-bit digital signal, and N latch circuits latch the N-bit logic signal. A multiplexer selects either the N-bit digital signal from the A/D converter, or the N-bit logic signals from the N latch circuits, and the selected signal at the output of the multiplexer is stored in an acquisition memory. By controlling the multiplexer selection, the number of analog channels and the digital channels can be controlled.
