ADQ14-FWPD pulse detection firmware for data driven acquisition
In this issue you can read about market leading 14-bit multi-channel
digitizer ADQ14 which is now extended with an advanced pulse detection
firmware. The pulse detection firmware includes software for high speed
is a market leading 14-bit digitizer with up to 4 channels and sampling at
up to 2 GSPS per channel. The firmware package FWPD enables data driven
pulse capture on individual channels, which enables the digitizer to
follow individual events in an optimal way. The time-stamp feature links
the timing of the pulses to each-other and a complete scenario is
recreated in the post analysis. There are two key elements; the
acquisition that is controlled by a pulse detection function, and the
length of each recording that is adapted to the pulse length. This means
that only interesting data is recorded and zeros (no data) are suppressed,
which saves valuable disk space.
The firmware option FWPD is very powerful automatic pulse identification
function. To support the user to do an efficient control of the firmware
there is a GUI and example code covering all aspects from digitizer
control to writing data to disk. This software package speeds up the
integration and shortens time to market.
SP Devices' Baseline Solutions
To identify pulses a stable pulse base reference is needed. This is
achieved by SP Devices' proprietary technology for digital baseline
stabilization (DBS) which tracks and controls the baseline with up to 22
bits precision. The DBS effectively suppresses long term fluctuations and
temperature gradients of the baseline and guarantees reliable pulse
analysis. In addition to that, the rapid changes in the baseline, for
example, from leakage of large pulse, are handled by a moving average
baseline tracking filter.
Real-time Pulse Analysis
The firmware option FWPD also includes real time pulse analysis functions
for peak and width measurements. The pulse measurement results are
available as lists of data or summarized in histograms. A custom real time
analysis of any parameter is easily implemented using the
development kit, which opens the FPGA to the user.
ADQ14 supports a multi-channel solution with synchronization of very many
channels. Below is a 16 channels system with disk storage.
Recording to disk example
The ADQ14-FWPD supports efficient pulse acquisition. The
also supports real-time storage to disk. Included with the firmware is
example software for saving the pulses to disk up to 3GByte/s.
