Digital data acquisition card takes up to 720MBit/s rates

February 29, 2016 // By
The Spectrum M4i.77xx series of Digital Data Acquisition cards represent a major performance breakthrough for test engineers who require high-speed digital data logging with multi-channel logic analysis over extended time periods. Based on Spectrum's proven M4i series PCI Express (PCIe) platform the cards are small and compact.

Each card comes equipped with 32 fully synchronous channels, large 4 GB on-board memory and a PCI Express x8 Gen 2 interface that offers outstanding data streaming performance. If more channels are needed, up to eight cards can be linked together with Spectrum's Star-Hub clock and trigger distribution system that fully synchronizes up to 256 channels.

Five different models are available with two offering differential inputs, for LVDS, (LV)PECL, (N)ECL and other differential signals, and three models with single-ended inputs for logic levels of 1.2, 1.5, 1.8, 2.5, 3.3, and 5.0 V. The cards are equipped with two VHDCI connectors for the digital channels as well as for the external trigger, clock input and clock output. These connectors also provide two separate multi-function inputs/outputs that can be individually programmed to perform different operations such as trigger out, status output (armed, triggered, ready, etc.) as well as providing additional asynchronous I/O lines.

Top of the range for the single-ended cards is the model M4i.7730-x8 that offers an internal data rate of 720 MBit/s. Other models are available with 125 and 250 MBit/s performance. For the models with differential inputs, the M4i.7735-x8 also boasts an internal data rate of 720 MBit/s while the more economical M4i.7725-x8 offers 250 MBit/s performance. The cards are fully programmable and work with Spectrum's own SBench 6 control software.
