Robust real-time waveform averaging
The Advanced Time Domain firmware option, FWATD, equips the ADQ7DC
digitizer with advanced tools for sophisticated time domain measurements.
Multiple steps of noise suppression are provided in order to achieve
extreme dynamic range so that rarely occurring weak signals can be
detected and distinguished from the noise.
In our recent update of FWATD we have improved the robustness of the
real-time waveform averaging feature so that corrupt data is automatically
discarded if the trigger source is producing unreliable triggers.
Traditional data acquisition systems lacking such protection mechanisms
will normally produce corrupt averaging outputs and the acquisition may
even come to a full stop. This is not acceptable in many of today's
systems where 24/7 operation is vital and therefore require fail-safe
Furthermore we have also introduced support for General Purpose
Input/Output (GPIO) in FWATD. This greatly simplifies communication and
control between the digitizer and the other parts of the system and helps
improve robustness and system-level synchronization even further. In
addition, the use of a compact yet robust GPIO D-Sub connector helps
keeping external cabling to a minimum.
