Spectrum’s range of Spectrum DN6.66xx Arbitrary Signal Generators offers 6 to 24 digitized channels, 16-bit resolution, a sample rate of 625 MS/s or 1.25 GS/s and 200 or 400 MHz bandwidth in a LAN eXtension for Instrumentation (LXI) format. It has been designed to meet the requirements of multi-channel applications for synchronized signal generation.
The DN6.66xx series complements its generatorNETBOX series of Arbitrary Waveform Generators (AWGs) by eight models (see table below). Complying with the LXI specifications, these instruments can be integrated into a test system via an Ethernet connection to a PC or a local area network (LAN).
Equipped with 16-bit digital-to-analog converters (DACs), they are equipped with 6 to 24 synchronous channels with sampling rates up to 1.25 GS/s, analogue bandwidth up to 400 MHz, memory depth of up to 1 Gech. per channel) and output voltage ranges up to ± 5 V in high impedance and up to ± 2.5 V in 50Ω.
All output channels are clocked and triggered synchronously. The clock system operates a phase locked control loop (PLL) which can be generated internally or, alternatively, from an external or reference clock. The time skew between the channels is, according to Spectrum, less than 130 picoseconds.
To generate long and complex waveforms, AWGs offer several modes of operation: Single-Shot, Loop, FIFO, Gating and Sequence Replay. The sequence mode separates the memory into different segments of different length and combines them according to the control sequence while offering the possibility of looping them.
The front panel I / O connectors provide access to multiple marker outputs, asynchronous digital inputs, asynchronous digital outputs, the trigger output, the run and arm status and the PLL reference clock.
These stand-alone instruments provide tools for generating a wide variety of waveforms. Simply connect the device to a host computer (such as a laptop or workstation) or anywhere on the corporate network and run Spectrum’s SBench6-Pro software.
SBench6-Pro comes standard with each instrument. It allows the user to control all operating modes and parameters of the AWG from a graphical user interface. The software also has features for creating waveforms, data analysis and documentation. The EasyGenerator function produces standard waveforms (sine, square, triangle, sawtooth, SINC and DC) from mathematical equations (for complex modulated waveforms). It is also possible to import and export to or from other devices such as digitizers and oscilloscopes or software such as MATLAB or LabVIEW. SBench6 also supports common data formats: ASCII, binary, and WAV.
In order to integrate the generatorNETBOX instruments into a test system, a software development kit (SDK) is included with the appropriate drivers. The SDK allows programming with several languages: C ++, Visual Basic, VB.NET, C #, J #, Delphi, Java and Python. Third-party software support is also provided free of charge for LabVIEW, LabWindows and MATLAB.
For remote operation of a GeneratorNETBOX generator, Spectrum provides an embedded server option, DN6.xxx-Emb. This option combines a processor unit (CPU), an accessible SSD, more memory capacity, and a remote software application development access method. The built-in server option creates an open platform on which users can run their own software while being connected remotely over a LAN. The option allows the generatorNETBOX to operate independently or, when connected to a local area network, within a wider test system.
