M2p.5943-x4, 16 bit 125MS/s 8 channel SE/DIFF signal capture card. Image with introductory video link describing dynamic performance, operating modes and software interface

The M2p.59xx series are Spectrum's latest release in their modular card series. Being modular means a wide choice of signal capture speeds, with models providing 5, 20, 40 , 80 and 125 mega samples per second A/D converters, all with high resolution (16 bit) performance. The card interface to the computer is x4-lane PCI express interface providing transfer speeds up to 700MBytes per second. This allows real time streaming to the computer without data bandwidth restriction for most versions of the M2p.59xx and where the fastest cards exceed this the deep 1 Gbyte on board memory, fitted as standard, still provides plenty of storage space.

The M2p.59xx uses a compact half-length PCI-express card length (168 x 107mm). This allows it to fit into a computer case of virtually any size. Although compact, these cards are highly versatile and feature rich. Each channel has a separate ADC and a fully individual programmable input amplifier with ranges between 200 mV and 10 V, with input offset for unipolar measurements. Models are available with up to 8 single-ended channels, easily switched via a software setting to provide up to 4 differential channels. All channels operate in perfect synchronisation. An integrated calibration circuit, excellent dynamic performance and ultra low internal noise all work together to provide precision results.

An optional digital card module (M2p59.xxxx-Dig) adds an extra 16 digital inputs. These are synchronised to the analogue sampling. This extends on the multi-purpose digital lines already available on the card. The connection to external equipment is via a second card mounted next the the M2p card. Please see the "Mixed-Mode" link lower down his page for more information.

Up to 16 M2p digitiser cards can be synchronised to expand the number of channels in one system, formore information see the Star Hub option below. Extensive support for programming includes Visual C++, Borland C++, Gnu C++, LabVIEW, MATLAB, Visual Basic, VB.NET, C#, J# and Delphi code.

Enhancements included more info

  • ABA mode - Variable sampling speed, jump to fast capture on trigger
  • Multiple Recording - multiple sequential signal capture using fast repetitive triggers, auto re-arm
  • Gated Sampling - signal recording length controlled by trigger level
  • Time stamp - records the time of each trigger event

Special (cost) options

  • Mixed-Mode operation - 16 additional digital multi-purpose I/O lines
  • Synchronisation Star Hub - Sample and trigger synchronise up to 16 cards
  • Remote Server - Programme, control and monitor Spectrum M2p, M2i, M3i or M4i cards in a remote location
  • SCAPP software - Access a CUDA-based GPU directly from the digitiser card. A very powerful way to digitise and process signals.
