I/O Card Offers Logic Analysis and Pattern Generation

May 13, 2021

Measuring just 168 mm x 107 mm (6.6 in. x 4.2 in.), a new digital I/O card from Spectrum Instrumentation (the M2p.7515-x4) economically generates and acquires digital signals. With 32 channels running at up to 125 MHz, the half-length PCIe card simply plugs into a PC to make a versatile tool for fast logic analysis or pattern generation.

In acquisition mode, the channels are compatible with 3.3 V and 5 V TTL signals. In generation mode, they deliver output levels of 0.2 V for low and 2.8 V for high states, with a high impedance load. With a range of different acquisition and replay modes plus 1 GB of on-board memory, the cards can acquire or generate almost any signal pattern. Modes include single shot, multiple or burst, gated, sequence and FIFO streaming. With transfer speeds of 700 Mbps over the PCIe bus, it is possible to load new data to memory while replaying previously stored signals.

For applications requiring more channels, Spectrum offers the Star-Hub clock and trigger distribution system. This option enables up to 16 different M2p-series cards - digitizers, arbitrary waveform generators or digital I/O cards - to share a common clock and trigger. A single system with 512 fully synchronized digital I/O channels is possible, and synchronization to other devices is realizable using a direct external clock or the reference inputs.

Running Windows or Linux operating systems, the cards are fully programmable and come with support for C++, LabVIEW, MATLAB, Visual Basic .NET, Python and other popular languages. SBench 6, Spectrum’s own software, is also available for signal generation, acquisition, display, processing, storage and reporting.

The M2p.7515-x4 is available to order now and has an exceptional five year warranty.
