16 bit multi-purpose digitizer
The MX.49xx cards allow recording of up to four channels with sampling rates of 25 MS/s or two channels with sampling rates of 50 MS/s. These cards offer outstanding A/D features both in resolution and speed for PXI. The cards can be switched between Single-Ended inputs with a programmable offset and true differential inputs. If used in differential mode each two inputs are connected together reducing the number of available channels by half. The 16 bit vertical resolution has four times the accuracy compared to 14 bit cards and sixteen times the accuracy compared with a 12 bit card. All boards of the MX.49xx series may use the whole installed on-board memory of up to 64 MSamples, completely for the currently activated number of channels.

FIFO modeThe 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.
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.
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.
PXI TriggerThe 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.
Spike TriggerThe trigger event is a slope inside the signal that is larger (or even smaller) than a programmed slope. Internally the difference of two adjacent samples is calculated and then compared to the programmed trigger level. This trigger mode allows the detection of signal distortions as needed for power line monitoring.
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.
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.
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.
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.
With a simple software command the inputs can individually be switched from single-ended (in relation to ground) to differential, without loosing any inputs. When the inputs are used in differential mode the A/D converter measures the difference between two lines with relation to system ground.
Digital Inputs (Optional)
This option acquires additional synchronous digital channels phase-stable with the analog data. When the option is installed there are 16/32 additional digital inputs which can be individually mulitplexed into the analog data in different formats reducing the analog resolution.
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.
