14 bit multi-purpose digitizer
The 6 models of the M3i.41xx series are designed for the fast and high quality data acquisition. Each of the input channels has its own monolithic A/D converter and its own programmable input amplifier. This allows the recording of signals simultaneously on both channels with 14 bit resolution without any phase delay between them. The card uses only one A/D converter even when running with 400 MS/s, guaranteeing best signal quality without any interleaving technology. The extremely large on-board memory allows long time recording even with the highest sampling rates.

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.
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 modeThe 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.
Star-Hub (Optional)The star-hub is an additional module allowing the phase stable synchronization of up to 8 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 4 card and 8 card version. The 4 card version doesn't need an extra slot.
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. Trigger conditions can be combined with logical conjunctions like OR to adopt to different application scenarios.
All boards can be triggered using a separate external trigger signal with a two level programmable window comparator. It's possible to use positive or negative edge. An internally recognized trigger event can - when activated by software - be routed to a multi purpose i/o connector to start external instruments.
Multi Purpose I/OThe 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.
TimestampThe 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.
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 PLLThe 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 ClockThe 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.
Selectable AC/DC CouplingEach analog channel contains a software selectable AC/DC coupling. When using the DC coupling all frequency parts of the signal including the DC offset are acquired. Selecting the AC coupling will only acquire frequency parts of the signal that are above a defined minimum bandwidth.
The on-board calibration can be run on user request and calibrates the amplifier against a dedicated internal high precision calibration source. After this calibration data is stored permanently in an on-board EEPROM and is automatically used for further acquisitions.
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 AmplifiersThe 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.
Selectable Input PathFor each of the analog channels the user has the choice between two analog input paths, both offering the highest flexibility when it comes to input ranges. The Buffered path has 1 MOhm termination that allows to connect standard oscilloscope probes to the card. The HF path on the other hand provides the highest bandwidth and the best signal integrity having a fixed 50 Ohm termination.
Selectable Low Pass FilterEach analog channel contains a software selectable low-pass filter to limit the input bandwidth. Reducing the analog input bandwidth results in a lower total noise and can be usefull especially with low voltage input signals.
Multi Purpose I/O
All M3i cards offer two universal multi purpose I/O lines, which can be separately programmed as either input or output. When used as outputs, these lines can be used to output card status signals like trigger-armed or to output the trigger to synchronize external equipment.
SMA Connectors (Optional)As an alternative to the standard SMB and MMCX connections the card can also be equipped with SMA connectors. The SMA connections are available for the analog input signals as well as for two of the additonal connections. These connections must be defined on the purchase order and can be a selection of: Trig-In, Trig-Out, Multi-Purpose X0, Clk-In, Clk-Out.

There are no additional SDK fees for the classical text-based programming. All boards are delivered with drivers for Windows 7, Windows 8, Windows 10 and Windows 11, all 32 bit and 64 bit.
