16 bit Arbitrary Waveform Generator
The M4x.66xx-x4 series arbitrary waveform generators (AWG) deliver the highest performance in both speed and resolution. The series includes PXI Express (PXIe) cards with either one, two or four synchronous channels. The large onboard memory can be segmented to replay different waveform sequences. The AWG features a PCI Express x4 Gen 2 interface that offers outstanding data streaming performance. The interface and Spectrum’s optimized drivers enable data transfer rates in excess of 2.8 GB/s so that signals can continuously replayed at a high output rate. While the cards have been designed using the latest technology they are still software compatible with the drivers from earlier Spectrum waveform generators. So, existing customers can use the same software they developed for a 10 year old 20 MS/s AWG card and for an M4x series 625 MS/s AWG.

FIFO modeThe FIFO mode is designed for continuous data transfer between measurement board and PC memory or hard disk. The write(replay) transfer rate reached depends on the motherboard and can be up to 1.4 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.
Repeated OutputWhen repeated output is used the data of the on-board memory is replayed continuously until a stop command is executed or N times. As trigger source one can use the external TTL trigger or the software trigger.
Sequence Replay ModeThe sequence mode allows to split the card memory into several data segments of different length. These data segments are chained up in a user chosen order using an additional sequence step memory with the ability to program loops and triggers and to reload data while output is running.
Single RestartWhen this mode is activated the data of the on-board memory will be replayed once after each trigger event. As Trigger source one can use the external TTL or software trigger.
Singleshot OutputWhen singleshot output is activated the data of the on-board memory is replayed exactly one time. As trigger source one can use the external TTL trigger or the software trigger.
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.
Gated ReplayThe Gated Sampling option allows data replay controlled by an external gate signal. Data is only replayed if the gate signal has a programmed level.
Multiple ReplayThe Multiple Replay option allows the fast repetition output on several trigger events without restarting the hardware. With this option very fast repetition rates can be achieved. The on-board memory is divided in several segments of same size. Each of them is generated if a trigger event occurs.
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.
Digital Outputs/Marker Outputs
Additional synchronous digital channels (markers) can be replayed phase-stable with the analog data. When this mode is active up to 3 additional digital marker outputs can be used by reducing the analog resolution of the D/A converter.
Programmable AmplitudeThe Spectrum Arbitrary Waveform Generators are equipped with a very wide programmable output amplitude. This allows to adapt the output signal level to the needs of the stimulated device while also having the maximum output resolution available for the signal.
High Bandwidth Option (Optional)This option is available for all 663x products with 1.25 GS/s. One option is needed per card/internal AWG of a generatorNETBOX. The bandwidth is extended from 400 MHz to 600 MHz. The maximum output level is reduced to ±480 mV. An external reconstruction filter is needed to remove mirror signals that result from higher Nyquist images.
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.
