8 bit high speed digitizer
The 9 models of the M4x.22xx-x4 Express series are designed for the high speed data acquisition. Each of the input channels has its own A/D converter and its own programmable input amplifier. This allows the recording of signals simultaneously on all channels without any phase delay between them. 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.
FIFO modeThe 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 1.7 GByte/s on a PXI Express x4 Gen2 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.
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 and a second separate external trigger with a single programmable level 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.
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.
PXI Reference ClockThe 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.
High Precision QuartzThe internal sampling clock of the card is generated using a high precision Quartz Clock which can be divided by a huge number of dividers to generate the sampling clock.
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.
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 range can be set to a value matching the real world signals. The high precision, high bandwidth 50 ohm inputs are optimized for acquisition of high bandwidth signals.
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/OAll M4i cards offer three 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.
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, Windows 10 and Windows 11, all 32 bit and 64 bit.
