Spectrum Unveils Small Size & Low Cost Digital I/O Card

Spectrum has launched a new Digital I/O card from Spectrum Instrumentation that offers engineers and scientists a cost-effective way to generate and acquire fast digital signals.

SpectrumThe model M2p.7515-x4 is a half-length PCIe card that measures just 168 x 107 mm (6.6 x 4.2 inches) in size.

Carsten Gralla, Managing Director at Spectrum Instrumentation, says: “The M2p.7515-x4 is our smallest Digital I/O card to date. It’s been designed to deliver a nice balance between price and performance, giving users a cost-effective solution whenever fast digital signals need to be acquired, generated and analyzed. It also complements our analog signal acquisition and generation products, fitting in perfectly with the mid-range M2p.59xx Digitizer series with 5 to 125 MS/s and 16-bit, plus the AWGs of the M2p.65xx series with 40 to 125 MS/s and 16-bit. These Digitizers and AWGs of the M2p family offer up to 8 channels per card.”

The tiny form factor means that it can be inserted into almost any desktop PC, turning it into a powerful tool for applications such as logic analysis or pattern generation. The card features 32 parallel channels that can be clocked at speeds up to 125 MHz.

The channels are accessed from two standard Hirose FX2 connectors located on the front panel.

When set for digital acquisition, the channels offer 3.3 V and 5 V TTL compatibility, making them suitable for use with a wide range of digital signals. In generation mode, the cards typically deliver output levels of 0.2 V for low states and 2.8 V for high states into high impedance.

Designed for maximum versatility, the cards come with 1 GByte of onboard memory as standard and a variety of different acquisition and replay modes.

For example, when generating patterns, the cards can operate in Single-shot, Multiple Replay (Burst), Gated Replay, Sequence and FIFO modes.

These modes make it possible to generate almost any signal pattern. It’s even possible to load new data to the onboard memory while replaying previously-stored signals.

Furthermore, the ability of the cards to use FIFO streaming, with a top transfer speed over the PCIe bus of 700 MB/s, enables users to generate constantly changing digital patterns for very long periods.
