General Information

The M2i.72xx Express pattern generator series gives the user the possibility to generate digital data with a wide range of output levels. For every 4 bit the LOW and HIGH levels can be programmed from -2.0 V up to +10.0 V. Even at high speeds you are not limited concerning the maximum output swing. This enables the user to drive devices of nearly any logic family, like ECL, PECL, TTL, LVDS, LVTTL, CMOS or LVCMOS. The potentially necessary differential signals are generated in hardware, so that only one data bit is used for each pair of differential signals.

In contrast to the parallel PCI buses PCI Express slots contain serial point to point connections. Each connection pair (lane) is able to reach a burst connection speed of 250 MBytes/s. The Spectrum PCI Express cards base on the most commonly used x1 lane slot type. One advantage of the PCI Express technology is the direct connection of each slot allowing a full transfer bandwidth for each single card. On the software side there is no difference between PCI/PCI-X or PCI Express. PCI Express is the bus standard for PC based systems for the next couple of years. Today's State-of-the-art motherboards normally have a couple of PCI Express slots but only one or two PCI-X slots. Spectrum's PCI Express x1 cards can be used in any standard PCI Express slot be it x1, x4, x8 or x16. Only some dedicated PCI Express graphics slots may not work.

BaseXIO (Optional)

The BaseXIO option offers 8 asynchronous digital I/O lines on the base card. The direction can be selected by software in groups of four. Two of these lines can also be used as additional external trigger sources. This allows the building of complex trigger conjunctions with external gated triggers as well as AND/OR conjunction of multiple external trigger sources like, for example, the picture and row synchronisation of video signals. In addition one of the I/O lines can be used as reference clock for the Timestamp counter.

FIFO mode

The FIFO mode is designed for continuous data transfer between measurement board and PC memory (up to 245 MB/s on a PCI-X slot, up to 125 MB/s on a PCI slot and up to 160 MB/s on a PCIe slot) or hard disk. The control of the data stream is done automatically by the driver on interrupt request. The complete installed on-board memory is used for buffer data, making the continuous streaming extremely reliable.

System Star-Hub (Optional)

Using the System Star-Hub for M2i series cards it is possible to synchronize several systems with each other having the same advantages that the standard Star-Hub gives. The system star-hub allows to extend the number of synchronous channels or set up multiple synchronous data streaming systems either for data storage or online calculations.

Repeated Output

When repeated output is used the data of the on-board memory is replayed continuously until a stop command is executed or N times. As trigger source one can use the external TTL trigger or the software trigger.

Sequence Replay Mode

The sequence mode allows to split the card memory into several data segments of different length. These data segments are chained up in a user chosen order using an additional sequence step memory with the ability to program loops and triggers and to reload data while output is running.

Single Restart

When this mode is activated the data of the on-board memory will be replayed once after each trigger event. As Trigger source one can use the external TTL or software trigger.

Singleshot Output

When singleshot output is activated the data of the on-board memory is replayed exactly one time. As trigger source one can use the external TTL trigger or the software trigger.

Star-Hub (Optional)

The star-hub is an additional module allowing the phase stable synchronization of up to 16 boards in one system. Independent of the number of boards there is no phase delay between all channels. The star-hub distributes trigger and clock information between all boards. As a result all connected boards are running with the same clock and the same trigger. All trigger sources can be combined with OR/AND allowing all channels of all cards to be trigger source at the same time. The star-hub is available as 5 card and 16 card version. The 5 card version doesn't need an extra slot.

External Trigger

All boards can be triggered using an external TTL signal. It's possible to use positive or negative edge also in combination with a programmable pulse width. An internally recognized trigger event can - when activated by software - be routed to the trigger connector to start external instruments.

Gated Replay

The Gated Sampling option allows data replay controlled by an external gate signal. Data is only replayed if the gate signal has a programmed level.

Multiple Replay

The Multiple Replay option allows the fast repetition output on several trigger events without restarting the hardware. With this option very fast repetition rates can be achieved. The on-board memory is divided in several segments of same size. Each of them is generated if a trigger event occurs.

Pulsewidth Trigger

Defines the minimum or maximum width that a trigger pulse must have to generate a trigger event. Pulse width can be combined with channel trigger, pattern trigger and external trigger. This makes it possible to trigger on signal errors like too long or too short pulses.

External Clock

Using a dedicated connector a sampling clock can be fed in from an external system. It's also possible to output the internally used sampling clock to synchronize external equipment to this clock.

High Precision PLL

The internal sampling clock of the card is generated using a high precision PLL. This powerful device allows to select the sampling rate with a fine step size making it possible to perfectly adopt to different measurement tasks. Most other cards on the market only allow the setup of fixed sampling rates like 100 MS/s, 50 MS/s, 25 MS/s, 10 MS/s, ... without any possibility to set the sampling rate to any value in between.

Reference Clock

The option to use a precise external reference clock (normally 10 MHz) is necessary to synchronize the board for high-quality measurements with external equipment (like a signal source). It's also possible to enhance the quality of the sampling clock in this way. The driver automatically generates the requested sampling clock from the fed in reference clock.

3rd Party Drivers

A lot of third-party products are supported by the Spectrum driver. Choose between LabVIEW, MATLAB, LabWindows/CVI and IVI. All drivers come with examples and detailed documentation.

Programming Examples

Programming examples for C++, Delphi, Visual Basic, C#, J#, VB.Net, Java, Python and LabWindows/CVI are delivered with the driver. Due to the simple interface of the driver, the integration in other programming languages or special measurement software is an easy task.

Linux

All cards are delivered with full Linux support. Pre compiled kernel modules are included for the most common distributions like RedHat, Fedora, Suse, Ubuntu or Debian. The Linux support includes SMP systems, 32 bit and 64 bit systems, versatile programming examples for Gnu C++ as well as the possibility to get the driver sources for own compilation.

Remote Server (Optional)

Using the Spectrum Remote Server it is possible to access the M2p/M2i/M3i/M4i/M4x card(s) installed in one PC (server) from another PC (client) via local area network (LAN), similar to using a digitizerNETBOX. To operate it the remote server option has to be activated by a software license for any of the Spectrum cards in the remote system.

SBench6

SBench 6 is a powerful and intuitive interactive measurement software. Besides the possibility to commence the measuring task immediately, without programming, SBench 6 combines the setup of hardware, data display, oscilloscope, transient recorder, waveform generator, analyzing functions, import and export functions under one easy-to-use interface.

Windows

This standard driver is included in the card delivery and it is possible to get the newest driver version free of charge from our homepage at any time. There are no additional SDK fees for the classical text-based programming. All boards are delivered with drivers for Windows 7, Windows 8 and Windows 10, all 32 bit and 64 bit.
