12 bit transient recorder
The MI.31xx series allows recording of two, four or eight channels with samplerates of 1 MS/s, 10 MS/s or 25 MS/s. Due to the proven design a wide variety of 12 bit A/D converter boards for PCI bus could be offered. These boards are available in several versions and different speed grades making it possible for the user to find an individual solution. As an option 4 digital inputs per channel could be recorded synchronously. The installed memory of up to 256 MSample will be used for fast data recording. It can completely be used by the currently active channels. If using slower samplerates the memory is switched to a FIFO buffer and data will be transferred online to the PC memory or to hard disk.

The cascading option synchronizes up to 4 Spectrum boards internally. It's the simplest way to build up a multi channel system. On the internal synchronisation bus clock and trigger signals are routed between the different boards. All connected boards are then working with the same clock and trigger information. There is a phase delay between two boards of about 500 picoseconds when this synchronization option is used.
Extra I/O (Optional)
The Extra I/O module adds 24 additional digital I/O lines and 4 analog outputs on an extra connector. These additional lines are independent from the standard function and can be controlled asynchronously. There is also an internal version available with 16 digital I/Os and 4 analog outputs that can be used directly at the rear board connector.
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 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.
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 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.
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.
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.
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.
Programmable Input OffsetMost 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.
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.
