Multi-channel AWG and digitizer in one device

With the ability to generate and record signals simultaneously, the hybridNETBOX from the manufacturer Spectrum Instrumentation is perfectly suited for measuring systems where automated tests in closed-loop or stimulus-response procedures are required. For example, echo signals such as radar, sonar, lidar or ultrasound can be generated and recorded simultaneously. Thanks to their multi-channel capability, these systems can also be tested if they are arrays of transmitters and receivers.

The hybridNETBOX is also suitable for ATE applications where components and assemblies have to be tested quickly and automatically. The functions and tolerances of test objects can be checked because many different complex signals can be generated in the simplest way with the hybridNETBOX. This is ideal for a wide range of applications, such as bus testing, MIMO communication, circuit testing, mechatronics and robotics.

The hybridNETBOX uses the latest 16-bit converter technology for low-noise signal generation and acquisition. All channels are synchronised and share common clock and trigger signals. The AWG channels can generate almost any waveform; output modes include Single-Shot, Loop, FIFO Streaming, Gated Replay and Sequence Replay – this allows easy creation of test routines, whether simple or complex.

The digitizer channels are designed to handle a wide range of input signals. They have variable input ranges from ±200 mV to ±10 V with fully programmable offset and selectable input impedance (50 Ohm and 1 Megaohm). All inputs can be switched between single-ended and differential operation. As with the AWG channels, there are a number of operating modes including single shot, FIFO streaming, multiple recording, gated sampling and ABA (Sampling Rate Switching). This is combined with a variety of flexible triggering modes (Channel, External, Software, Window, Pulse, Re-Arm, Peak, Logic and Delay) to ensure that all events can be captured.    

Additional multi-purpose digital I/O connectors can be used as marker outputs, for example, to control external devices in the test setup in full synchronism with the signals from the AWG channels.

These instruments are LXI-compatible and can therefore be easily controlled and operated. The device is simply connected to a PC or a network via the GBit Ethernet port on the back.

The scope of delivery includes the SBench 6 Professional software for hardware control as well as for signal generation, signal acquisition, data analysis, storage and documentation. With SBench 6 waveforms can be created using standard functions and mathematical equations. The programmable hybridNETBOX contains drivers for Windows and Linux operating systems as well as programming examples for C ++, LabVIEW, MATLAB, Visual Basic .NET, Python and other programming languages.

The hybridNETBOX is available in six versions, offering two, four or eight pairs of matched AWG and digitiser channels. Output and sampling rates of 40, 80 and 125 megasamples per second are possible.
