M78 - 4-Channel Digital Oscilloscope

PDF¤U¸ü

Product Description

The M78 is based on the M-Module ANSI mezzanine standard. It can be used as an I/O extension in any type of bus system, i.e. CPCI, PXI, VME or on any type of stand-alone SBC. Appropriate M-Module carrier cards in 3U, 6U and other formats are available from MEN or other manufacturers.
The M78 is an M-Module for acquisition of up to four analog and eight digital signals with a wide bandwidth at a maximum resolution of 12 bits and a sampling rate of up to 50MS/s. A local 16MB RAM buffers the converted values. The buffer contents can be transferred to the host.
The M-Module has onboard input signal conditioning. This is implemented adding a small PCB, which guarantees maximum flexibility for manifold applications.
Variable trigger functions permit application of the M78 as a genuine digital storage oscilloscope and implementation of modular multichannel systems. Typical applications include simulators, analysis systems, high-speed data loggers or automotive diagnostic systems.
The M78 is software compatible with the 1-channel 12-bit/40-MHz oscilloscope M67.
