Compliance
FCC/Canadian Interference-Causing Equipment Standard (ICES-003)
Compliance*
Determining FCC Class
The Federal Communications Commission (FCC) has rules to protect wireless
communications from interference. The FCC places digital electronics into two
classes. These classes are known as Class A (for use in industrial-commercial
locations only) or Class B (for use in residential or commercial locations).
Depending on where it is operated, this product could be subject to restrictions
in the FCC rules. (In Canada, the department of Innovation, Science and
Economic Development (ISED), regulates wireless interference in much the
same way).
Digital electronics emit weak signals during normal operation that can affect radio,
television, or other wireless products. By examining the product you purchased, you
can determine the FCC Class and therefore which of the two FCC/ISED Warnings
apply in the following sections. (Some products may not be labeled at all for FCC; if
so, the reader should then assume these are Class A devices.)
FCC Class A products only display a simple warning statement of one paragraph
in length regarding interference and undesired operation. Most of our products
are FCC Class A. The FCC rules have restrictions regarding the locations where
FCC Class A products can be operated.
FCC Class B products display either an FCC ID code, starting with the letters
EXN, or the FCC Class B compliance mark.
Consult the FCC website www.fcc.gov for more information.
FCC/ISED Warnings
This equipment generates and uses radio frequency energy and, if not installed
and used in strict accordance with the instructions in this manual and the CE
Mark Declaration of Conformity**, may cause interference to radio and
television reception. Classification requirements are the same for the Federal
Communications Commission (FCC) and Innovation, Science and Economic
Development (ISED) Canada.
Changes or modifications not expressly approved by AlazarTech could void the
user’s authority to operate the equipment under the FCC/ISED Rules.

vi ATS9373 User Manual
Class A
Federal Communications Commission
This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be required to correct the
interference at his own expense.
Innovation, Science and Economic Development Canada
This Class A digital apparatus meets all requirements of the Canadian
Interference-Causing Equipment Standard (ICES-003). Cet appareil numérique
de la classe A respecte toutes les exigences du Règlement sur le matériel
brouilleur du Canada.
Compliance to EU Directives
Readers in the European Union (EU) must refer to the Manufacturer's
Declaration of Conformity (DoC) for information** pertaining to the CE Mark
compliance scheme. The Manufacturer includes a DoC for most every hardware

ATS-SDK API
The ATS-SDK API is used for programming the ATS9373 in C/C++, C#,
LabVIEW, MATLAB and Python. It provides the exact same API that is used for
writing AlazarDSO software. To help you get started, ATS-SDK comes with
examples you can use or modify.
The ATS-SDK contains the necessary files to develop applications both under
Windows and Linux.
ATS-GPU
Interfacing waveform digitizers to GPUs involves creating a software mechanism
to move data from one to the other and back to user buffers. The standard
techniques used most often can get the job done, but feature very low data
throughput due to software overheads.
AlazarTech designed ATS-GPU so this software bottleneck is eliminated and data
can be moved from AlazarTech digitizers to GPUs and from GPUs to user buffers
at full PCIe bus speeds.
Once the data is available in GPU memory, many types of digital signal
processing (DSP) can be done on this data at near-hardware speeds.
The ATS-GPU library provides a framework to allow real-time processing of data
from AlazarTech PCIe digitizers on a CUDA®-enabled GPU. To help you get
started, ATS-GPU-BASE comes with an example of a user application that
performs very simple signal processing (data inversion) you can use or modify.
ATS-GPU-OCT is the optional OCT Signal Processing library for ATS-GPU. It
contains floating point FFT routines that have also been optimized to provide the
maximum number of FFTs per second. Kernel code running on the GPU can do
zero-padding, apply a windowing function, do a floating-point FFT, calculate the
amplitude and convert the result to a log scale. It is also possible to output
phase information.
ATS-GPU-NUFFT is an extension of ATS-GPU-OCT that allows non-uniform FFTs to
be performed on data acquired uniformly in time domain using a fixed sampling
rate. For SS-OCTs where the wavelength does not vary linearly in time, a fixed
sampling rate results in data that is non-uniformly distributed in frequency
domain. ATS-GPU-NUFFT allows linearized FFTs to be performed on such data.
The non-uniform FFT requires a linearization function that describes how the
wavelength of the SS-laser evolves during a sweep of the spectrum. Linearization
function can either be user defined or measured directly from a k clock signal.
