General Information

The M2p.75xx series of fast digital I/O cards allow to acquire or replay digital patterns with a programmable speed of up to 125 MS/s. The direction can be switched by software between input (digital data acquisition) and output (digital pattern generation). The on-board memory of 1 GByte can be completely used for digital pattern. Furthermore the on-board memory can be switched to a FIFO buffer allowing to continuously stream data in either output or input direction.

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 powerful x4 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. PCI Express is today's bus standard for PC based systems. Spectrum's PCI Express x4 cards can be used in any standard PCI Express slot with x4, x8 or x16. They physically do not fit into one lane (x1) PCIe slots.

FIFO mode

The FIFO mode is designed for continuous data transfer between measurement board and PC memory or hard disk. The read (acquisition) transfer rate reached depends on the motherboard and can be up to 700 MByte/s on a PCI Express x4 Gen1 slot. 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.

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.

Ring buffer mode

The ring buffer mode is the standard mode of all acquisition boards. Data is written in a ring memory of the board until a trigger event is detected. After the event the posttrigger values are recorded. Because of this continuously recording into a ring buffer there are also samples prior to the trigger event visible: Pretrigger = Memsize - Posttrigger.

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 allowing all channels of all cards to be trigger source at the same time. The star-hub is available as either piggy-back version (extending the width of the card) or as extension version (extending the length of the card to full length).

External Trigger Input

The boards can be triggered using an external trigger input, that has the same exact interface capabilities as the installed data lines, either single-ended with programmable threshold or differential.

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.

Gated Sampling

The Gated Sampling option allows data recording controlled by an external gate signal. Data is only recorded if the gate signal has a programmed level. In addition a pre-area before start of the gate signal as well as a post area after end of the gate signal can be acquired. The number of gate segments is only limited by the used memory and is unlimited when using FIFO mode.

Multi Purpose I/O

The card offers universal multi purpose I/O lines, which can be separately programmed as either input or output. These lines can be used as additional TTL trigger inputs for more complex trigger conditions.

Multiple Recording

The Multiple Recording option allows the recording of several trigger events with an extremely short re-arming time. The hardware doesn't need to be restarted in between. The on-board memory is divided in several segments of the same size. Each of them is filled with data if a trigger event occurs. Pre- and posttrigger of the segments can be programmed. The number of acquired segments is only limited by the used memory and is unlimited when using FIFO mode.

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.

Timestamp

The timestamp option writes the time positions of the trigger events in an extra memory. The timestamps are relative to the start of recording, a defined zero time, externally synchronized to a radio clock, or a GPS receiver. With this option acquisitions of systems on different locations can be set in a precise time relation.

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#, VB.Net, Java, Python, Julia 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.

SCAPP - CUDA Interface (Optional)

The SDK option allows to directly transfer data between the Spectrum card and a NVIDA CUDA GPU card. The GPU card is optimized for parallel data processing. The package comes with a number of detailed examples like FFT or block average. The package also supports Nvidia Jetson Xavier AGX devices.

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.
