Trigger - The trigger block in the ADQ has several configuration options. This application note describes the different triggering functions that are available, and how they should be configured. The differences and similarities between ADQ V5 and ADQ V6 digitizers are highlighted.
Waveform Averaging - The ADQ digitizers are equipped with real time firmware support for waveform averaging. This document describes the different averaging functions that are available, and how they should be configured.
Positive bias - Some of the ADQ series of digitizers is offered with a biased input. This is used for systems with unipolar pulses. A biased analog input makes it possible to use the entire signal range for the unipolar signal. This document is based on ADQ1600-PB. Differences may exist on other digitizer models.
Acquisition modes - The ADQ series of digitizers supports several modes of acquisition to serve a large variety of measurement situations. This application note gives an overview of the available acquisition modes and provides guidelines on when to use the different modes.
Clocking - The ADQ series of digitizers has an advanced clock system for flexible synchronization to external equipment. This document is a general description of the clock system. It also contains examples on how to use the clock system.
Playback function and equalizer on SDR14 - This application note describe how to connect the analog inputs to the analog outputs inside the SDR14 to create a loopback function.
In big physics experiments it is often crucial to perform synchronized data acquisition on a large number of channels simultaneously. Learn how CERN explore the origins of the universe in the neutron Time-of-Flight (n_TOF) experiment by using the ADQ412 to implement up to 100 synchronized channels.
