Digitizers optimized for pulsed-data capture
In this newsletter we highlight some advantages with SP Devices'
digitizer products for pulsed-data applications such as LIDAR and
mass-spectrometry.
ADQ1600TD - optimized for pulse data capture with high speed and
resolution
Since its introduction the ADQ1600 has enabled our customers to perform
data acquisition with an unmatched combination of high sampling rate and
vertical resolution enabled by SP Devices' proprietary ADX interleaving
technology. The product has gained significant popularity and as a result
been widely adopted by customers engaged in both time and frequency domain
applications.
With the introduction of our performance enhancement techniques for
pulse-data applications we are now offering a new and additional version
of the ADQ1600 which we call
ADQ1600TD
(as in time-domain). The
ADQ1600TD
contains both hardware and firmware optimizations - including DBS and
programmable DC-bias - that enable optimized pulse capture.
Our commitment to customers working with frequency domain applications
remains intact, but to better distinguish between the models we are
choosing to rename the ADQ1600 to
ADQ1600RF. The performance of this product remains that same as it was on the
ADQ1600 so the only difference is the new name.
Both models continue to offer a rich feature set as well as open access to
the on-board Xilinx Virtex 6 LX240T FPGA.
Please do not hesitate contacting us if you have questions and/or if you
need recommendations on which model to chose.
Achieve one extra bit of resolution and insensitivity to temperature
variations!
SP Devices provides high-speed digitizers in the 12 to 14-bit domain. Our
GS/s acquisition capabilities offer sub-nanosecond time-resolution.
AC-coupled digitizer front-ends offer the best bandwidth, noise, and
distortion performance compared with other alternatives. SP Devices'
AC-coupled digitizers for pulsed-data applications do not suffer from the
two main drawbacks that are otherwise typical in AC-coupled configurations
- limited dynamic range for unipolar signals and fluctuating pulse
baseline due to temperature drift and charge accumulation.
Since SP Devices' AC-coupled digitizers are equipped with a
digitally-programmable analog bias after the AC-coupling, unipolar signals
can utilize the full input range of the ADC irrespectively of the
direction of the pulse, thereby effectively
saving one bit of resolution.
SP Devices' AC-coupled digitizers are also available with a proprietary
digital baseline stabilization technology (DBS) providing excellent
stability of the output signal baseline. With DBS, all recorded pulses
will start from the same user-defined level and pulsed-data acquisition
tasks become totally insensitive to temperature effects.
This provides the best possible conditions for the most demanding
time-of-flight measurements.
