General Information

The hybridNETBOX DN2.82x series internally consists of a Digitizer and an AWG that can run together or independently. That allows simultaneous data generation and data acquisition for stimulus-response tests, ATE applications, MIMO applications or closed-loop applications. Used independently, the digitizer can acquire test data in the field and the AWG can replay this test data in lab. The hybridNETBOX offers 14/16 bit resolution and is available with digitizer sampling rates of up to 500 MS/s and AWG sampling rates of up to 1.25 GS/s. The hybridNETBOX can be installed anywhere in the company LAN and can be remotely controlled from a host PC.

The digitizerNETBOX and generatorNETBOX offer a powerful GBit Ethernet connection and are fully LXI compatible. The netbox can be used as tabletop instrument or 19" rack mount operation. It can be connected anywhere in your LAN or directly point-to-point with your Laptop/Workstation. A full option package and software package including SBench 6 Professional is included. The first data acquisition can be done within minutes: connect power + ethernet + signals, swicth on, install software on client PC, detect the digitizerNETBOX/generatorNETBOX with Discovery, start SBench 6, do the first acquisition!

ABA Mode

The optional ABA mode combines slow continuous data recording with fast acquisition on trigger events. The ABA mode works like a slow data logger combined with a fast digitizer. The exact position of the trigger events is stored as timestamps in an extra memory.

FIFO mode

The FIFO mode is designed for continuous data transfer between the digitizerNETBOX and the host PC. The transfer speed is depending on the Ethernet connection between box and host and is in the region of 40 MB/s to 60 MB/s. 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.

Ring buffer mode

The ring buffer mode is the standard mode of all acquisition boards. Data is written in a ring memory of the board until a trigger event is detected. After the event the posttrigger values are recorded. Because of this continuously recording into a ring buffer there are also samples prior to the trigger event visible: Pretrigger = Memsize - Posttrigger.

Channel Trigger

The data acquisition boards offer a wide variety of trigger modes. Besides the standard signal checking for level and edge as known from oscilloscopes it's also possible to define a window trigger. Trigger conditions can be combined with logical conjunctions like OR to adopt to different application scenarios.

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.

Gated Sampling

The Gated Sampling option allows data recording controlled by an external gate signal. Data is only recorded if the gate signal has a programmed level. In addition a pre-area before start of the gate signal as well as a post area after end of the gate signal can be acquired. The number of gate segments is only limited by the used memory and is unlimited when using FIFO mode.

Multiple Recording

The Multiple Recording option allows the recording of several trigger events with an extremely short re-arming time. The hardware doesn't need to be restarted in between. The on-board memory is divided in several segments of the same size. Each of them is filled with data if a trigger event occurs. Pre- and posttrigger of the segments can be programmed. The number of acquired segments is only limited by the used memory and is unlimited when using FIFO mode.

Multiple Replay

The Multiple Replay option allows the fast repetition output on several trigger events without restarting the hardware. With this option very fast repetition rates can be achieved. The on-board memory is divided in several segments of same size. Each of them is generated if a trigger event occurs.

Timestamp

The timestamp option writes the time positions of the trigger events in an extra memory. The timestamps are relative to the start of recording, a defined zero time, externally synchronized to a radio clock, or a GPS receiver. With this option acquisitions of systems on different locations can be set in a precise time relation.

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.

On-board Calibration

The on-board calibration can be run on user request and calibrates the amplifier against a dedicated internal high precision calibration source. After this calibration data is stored permanently in an on-board EEPROM and is automatically used for further acquisitions.

Programmable Input Amplifiers

The analog inputs can be adapted to real world signals using a wide variety of settings that are individual for each channel. By using software commands the input termination can be changed between 50 Ohm and 1 MOhm and one can select an input range matching the real world signal.

Programmable Input Offset

Most of the Spectrum A/D cards offer a user programmable signal offset opening the Spectrum boards to a wide variety of setups. The signal offset at least covers a range of +/-100 % of the currently selected input range making unipolar measurements with the card possible. Besides this the input range offset can be programmed individually allowing a perfect match of the A/D card section to the real world signal.

Synchronous Sampling

All acquisition cards from Spectrum are built with a completely synchronous design. Every channel has its own independent input amplifier as well as an independent ADC allowing to program all input channel related settings individually for each channel.

Multi Purpose I/O

All M4i cards offer three universal multi purpose I/O lines, which can be separately programmed as either input or output. When used as outputs, these lines can be used to output card status signals like trigger-armed or to output the trigger to synchronize external equipment.

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.

Embedded Server (Optional)

The option turns the digitizerNETBOX in a powerful PC that allows to run own programs on a small and remote data acquisition system. The digitizerNETBOX is enhanced by more memory, a powerful CPU, a freely accessable internal SSD and a remote software development access method (SSH)

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.

Remote Access

The digitizerNETBOX can be remotely accessed from any current Windows (starting with Windows XP) 32 bit or 64 bit system or Linux (starting with Kernel 2.6) 32 bit or 64 bit system by Ethernet. The remote access is done in the very exact programming like a locally installed product allowing to use any of the supported software packages.

SBench6

SBench 6 is a powerful and intuitive interactive measurement software. Besides the possibility to commence the measuring task immediately, without programming, SBench 6 combines the setup of hardware, data display, oscilloscope, transient recorder, waveform generator, analyzing functions, import and export functions under one easy-to-use interface.
