ABA Mode

The 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.

Block Average (Optional)

The Block Average Module improves the fidelity of noisy repetitive signals. Multiple repetitive acquisitions with very small dead-time are accumulated and averaged. Random noise is reduced by the averaging process improving the visibility of the repetitive signal.

Block Statistics (Optional)

The Block Statistics and Peak Detect Module implements a widely used data analysis and reduction technology in hardware. Each block is scanned for minimum and maximum peak and a summary including minimum, maximum, average, timestamps and position information is stored in memory.

Boxcar Average

The Boxcar averaging function smooths out high frequency noise to give a clear signal. It is most useful in situations where signals have been oversampled and it can be used to increase vertical resolution, lower noise and improve dynamic characteristics such as signal-to-noise ratio (SNR) and spurious free dynamic range (SFDR). It uses a mathematical signal processing function to effectively recalculate the vertical value of each acquired data point by averaging it with adjacent sample points.

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.

8 Bit Mode

The digitizer allow to optionally reduce the resolution of the A/D samples from their native resolution down to 8 bit resolution, such that each sample will only occupy one byte in memory instead of the standard two bytes required. This does not only allow to store douple the amount of samples in the on-board memory, but also reduces the required bandwidth over the PCIe bus by half and also to the storage
devices, such as SSD or HDD. Using this mode much higer streaing speeds are reachable.

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.
