General Information

The 17 models of the M2i.30xx series are designed for the fast and high quality data acquisition. Each of the (up to four) input channels has its own A/D converter and its own programmable input amplifier. This allows the recording of signals simultaneously on all channels with 12 bit resolution without any phase delay between them. The extremely large on-board memory allows long time recording even with the highest sampling rates. All boards of the M2i.30xx series may use the whole installed on-board memory for the currently activated number of channels. A FIFO mode is also integrated on the board. This allows continuous acquisition of data for online processing or for data storage to hard disk.

The PCI bus in the form that is used today was first introduced in 1995. The last years it has been the most common platform for PC based instrumentation boards. Nowadays PCI based systems are more and more superseded by PCI Express based systems. Its world-wide range of installations, especially in the consumer market, still makes it a platform with good value. Based on the PCI bus the PCI-X bus was specified for applications needing a higher data throughput. On the PCI-X bus there are bus frequencies up to 133 MHz and data bus widths up to 64 bit available. The M2i and M3i cards use the PCI-X bus with 66 MHz to gain a high data throughput. All PCI and PCI-X cards from Spectrum are compatible to PCI as well as to PCI-X with 33 MHz up to 133 MHz bus frequency.

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.

Ring buffer mode

The ring buffer mode is the standard mode of all oscilloscope 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/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.

ABA Mode

The optional ABA mode combines slow continuous data recording with fast acquisition on trigger events. The ABA mode works like a slow data logger combined with a fast digitizer. The exact position of the trigger events is stored as timestamps in an extra memory.

Channel Trigger

The data acquisition boards offer a wide variety of trigger modes. Besides the standard signal checking for level and edge as known from oscilloscopes it's also possible to define a window trigger. All trigger modes can be combined with the pulsewidth trigger. This makes it possible to trigger on signal errors like too long or too short pulses.

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 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.

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.

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.

Digital Inputs (Optional)

This option acquires additional synchronous digital channels phase-stable with the analog data. When the option is installed and activated additional digital inputs are stored in the unused bits of each ADC word (2 digital inputs on 14 bit A/D and 4 digital inputs on 12 bit A/D)

Programmable Input Amplifiers

The analog inputs can be adapted to real world signals using a wide variety of settings that are individual for each channel. By using software commands the input termination can be changed between 50 Ohm and 1 MOhm and one can select an input range matching the real world signal.

Programmable Input Offset

Most of the Spectrum A/D cards offer a user programmable signal offset opening the Spectrum boards to a wide variety of setups. The signal offset at least covers a range of +/-100 % of the currently selected input range making unipolar measurements with the card possible. Besides this the input range offset can be programmed individually allowing a perfect match of the A/D card section to the real world signal.

Pseudo Differential Inputs (Optional)

With a simple software command two single-ended inputs can be combined to one differential channel. The difference is calculated in hardware on the digital side. The difference calculation is done in real-time using the current sampling rate of the card. Both inputs of the difference signal are still related to GND.

3rd Party Drivers
