Spectrum's arbitrary generators DN2.65x.

Spectrum’s DN2.65x compact generators deliver up to 16 arbitrary signals

  • Spectrum Instrumentation completes its generatorNetbox family of arbitrary signal generators (AWG) with the DN2.65x series.
  • These compact instruments in LXI format can generate up to 16 electronic signals simultaneously.

The new generators of the generatorNetbox family are portable. They can also be integrated into a test bench, rack-mounted with other equipment or used in mobile systems (12 or 24 V DC power supply optional).

The new DN2.65x series of generators in the generatorNetbox range includes six instruments with various configurations and performance levels with 4, 8 or 16 synchronous channels. All instruments are equipped with a 16-bit digital-to-analog (DAC) conversion system to generate signals in a frequency range from DC to 60 MHz with an output rate of 40 MS/s or 125 MS/s. They connect via an Ethernet connection to a PC or a local area network (LAN) for remote control.

It is possible to generate signals with a programmable output level up to ±6 V in high impedance or ±3 V in 50 Ohms. These instruments have an on-board memory capacity of up to 2 x 512 Mpts. Different operating modes ensure the generation of long and complex waveforms: Single-Shot, Loop, FIFO, Gated and Sequence Replay modes. Signals can even be generated while loading new waveform data into the on-board memory.

Each generator channel is clocked by a phase-locked loop (PLL) that can be generated internally or from an external clock or reference. Four separate filters are available to optimize the quality of the output signal and ensure excellent dynamic performance. For example, the noise spectral density (NSD) is as low as -142 dBm/Hz, the total harmonic distortion (THD) is -74 dB, the signal-to-noise ratio (SNR) is 90 dB and the Spurious Free Dynamic Range (SFDR) can reach 97 dB.

These generators are equipped with versatile front-panel I/O connectors that provide access to synchronous digital outputs (markers), trigger outputs, run and arm status, PLL reference clock or asynchronous I/O lines.

Spectrum’s SBench 6 Professional software is included as standard with each device. It allows users to control all operating modes and hardware parameters from a graphical user interface. The software also has various integrated functions for waveform creation, data analysis and documentation. This includes the EasyGenerator function to produce standard waveforms such as sinusoidal, rectangular, triangle, sawtooth, SINC and DC. Waveforms can also be created from equations, imported from other devices (such as digitizers and oscilloscopes) or other software. SBench 6-Pro even allows the import and export of data in ASCII, binary and WAV formats.

The generators come with drivers, so users can write their own control programs in almost all common programming languages: C++, Visual Basic, VB.NET, C#, J#, Delphi and Python. Third-party software support is also provided for LabVIEW, LabWindows and MATLAB.
