Product:
M4i.9620-x8
16 bit DDS Generator up to 200 MHz
Description:
The M4i.96xx-x8 series DDS generators deliver the highest performance in both speed and resolution. The series includes PCIe cards with either one, two or four synchronous channels. DDS – Direct Digital Synthesis – is a method for generating sine waves from a single, fixed-frequency reference clock and is widely used in signal generation applications. The DDS functionality implemented on Spectrum Instrumentation’s AWG platform is based on the principle of adding multiple “DDS cores” to generate a multi-carrier (multi-tone) signal, with each carrier having its own well-defined frequency, amplitude and phase. In addition to these static parameters, there are also build in dynamic parameters like frequency slope and amplitude slope to allow for intrinsic linear changes for multiple cores.

The multi-carrier DDS option allows to program and combine multiple DDS cores in hardware allowing to generate multi-tone sine signals with a few DDS commands. DDS commands allow manipulation of frequency, amplitude and phase as well as advanced functions liek frequencya or amplitude slopes, all with single DDS commands.
Digital Pulse Generator Option (Optional)
The digital pulse generator option adds three internal independent pulse generators with programmable duty cycle, output frequency, delay and number of loops. These pulse generators can be triggered by software, hardware trigger or can trigger each other allowing to form complex pulse schemes to drive external equipment or experiments. The pulse generators can be outputted on the existing multi-XIO lines or can be used to trigger the instrument internally. Time resolution of the pulse generator depends on the cards type and the selected sampling rate and can be found in the technical data section.
External 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.
External Clock
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 PLL
The 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 Clock
The 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 Amplitude
The 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.
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.
