General Information

The MX.70xx series of fast digital I/O boards offers a resolution between 1 bit and 32 bit with a maximum sampling rate of 125 MS/s (60 MS/s). Every 16 bit / 32 bit of the board can be separately programmed for input or output. The on-board memory of up to 128 MByte can be completely used for recording or replaying digital data. Alternatively the MX.70xx can be used in FIFO mode. Then data is transferred on-line to PC memory or hard disk. The internal standard synchronisation bus allows synchronisation of several MX.xxxx boards. Therefore the MX.70xx board can be used as an enlargement to analogue boards.

Based on the CompactPCI 3U standard the PXI (PCI eXtensions for Instrumentation) enhancement was defined especially for the measurement user. In this specification additional lines for measure ment purposes are defined. There is a high-quality 10 MHz reference clock, as well as a star trigger and a trigger bus. The Spectrum boards support all these features, most notably with the help of the reference clock and the star trigger module for an easy combination of products - in including those from different companies. Since September 2003 Spectrum is a member of the PXI system alliance. The Spectrum PXI cards run in a plain CompactPCI 3U slot as well as in a dedicated PXI 3U slot. If using the MX series in a plain CompactPCI slot the PXI features will not be available.

FIFO mode

The FIFO mode is designed for continuous data transfer between measurement board and PC memory (with up to 100 MByte/s) 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.

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.

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.

PXI Star Trigger Card (Optional)

The MX.9010 is a special PXI star trigger card designed for the Spectrum PXI products. It allows to route clock and trigger synchronously to all PXI slots that are connected to the star trigger slot. The PXI reference clock is overwritten and external trigger events are synchronized to the sampling clock.

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.

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.

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.

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.

Pattern Trigger

For every bit of the digital input the pattern trigger defines individually the expected level or sets the bit to "don't care'. In combination with pulsewidth counter and edge detection the pattern trigger could be used to recognise a huge variety of trigger events.

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.

PXI Trigger

The Spectrum cards support star trigger as well as the PXI trigger bus. using a simple software commend one or more trigger lines can be used as trigger source. This feature allows the easy setup of OR connected triggers from different cards.

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.

PXI Reference Clock

The card is able to use the 10 MHz reference clock that is supplied by the PXI system. Enabled by software the PXI reference clock is feeded in the on-board PLL. This feature allows the cards to run with a fixed phase relation.

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.

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.
