M4x.9621-x4

16 bit DDS Generator up to 200 MHz

Description:

The M4x.96xx-x4 series DDS generators deliver the highest performance in both speed and resolution. The series includes PXCIe cards with either 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.

Facts & Features:

  • 2 channels with 50 DDS cores (tones) on one channel
  • Fast 16 bit DAC with FPGA-based DDS
  • Two or four channels with 625 MS/s DAC output rate
  • DDS frequency DC to 200 MHz
  • Up to 50 DDS cores on one channel
  • Native DDS-commands: Frequency, Amplitude, Phase, Frequency Slope, Amplitude Slope, Wait for trigger, Digital outputs
  • DDS commands can be issued with 6.4 ns spacing
  • Output level ±80 mV to ±2.5 V into 50 Ohm (±160 mV to ±5 V into high-impedance loads)
  • Fixed trigger to output delay
  • Ultra Fast PCI Express x8 Gen 2 interface
  • Huge on-board memory for 512 Million DDS Commands
  • PXIe x4 Gen 2 Interface
  • Works with all PXIe and PXI hybrid slots
  • PXIe 3U format, 2 slots wide
  • Transfer Speed of up to 10 Million DDS Commmands per second

FIFO mode

The 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.

Multi-Carrier DDS mode

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.

PXI Reference Clock

The 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 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.

3rd Party Drivers

A lot of third-party products are supported by the Spectrum driver. Choose between LabVIEW, MATLAB, LabWindows/CVI and IVI. All drivers come with examples and detailed documentation.

Programming Examples

Programming examples for C++, Delphi, Visual Basic, C#, VB.Net, Java, Python, Julia and LabWindows/CVI are delivered with the driver. Due to the simple interface of the driver, the integration in other programming languages or special measurement software is an easy task.

Linux

All cards are delivered with full Linux support. Pre compiled kernel modules are included for the most common distributions like RedHat, Fedora, Suse, Ubuntu or Debian. The Linux support includes SMP systems, 32 bit and 64 bit systems, versatile programming examples for Gnu C++ as well as the possibility to get the driver sources for own compilation.

Remote Server (Optional)

Using the Spectrum Remote Server it is possible to access the M2p/M2i/M3i/M4i/M4x card(s) installed in one PC (server) from another PC (client) via local area network (LAN), similar to using a digitizerNETBOX. To operate it the remote server option has to be activated by a software license for any of the Spectrum cards in the remote system.

Windows

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.
