Compliance
FCC/Canada Radio Frequency Interference 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 communications (DOC), of Industry Canada, 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/DOC 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 a FCC ID code, starting with the letters EXN, or
the FCC Class B compliance mark.
Consult the FCC web site http://www.fcc.gov for more information.
FCC/DOC 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 the Canadian Department of Communications (DOC).
Changes or modifications not expressly approved by AlazarTech Inc. could void the
user’s authority to operate the equipment under the FCC Rules.
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.
Canadian Department of Communications
This Class A digital apparatus meets all requirements of the Canadian InterferenceCausing Equipment Regulations. Cet appareil numérique de la classe A respecte
toutes les exigences du Règlement sur le matériel brouilleur du Canada.

1. Physically install the digitizer in your computer
Identify an unused PCI Express slot on your
motherboard. As per PCI Express specification, the
8-lane ATS9626 card is compatible with any 8-lane
or 16-lane connector on the motherboard.
Make sure that your computer is powered off before
you attempt to insert the ATS9626 digitizer in one of
the free PCI Express slots.
For best noise performance, leave as much room as
possible between your ATS9626 and other hardware.
Always screw the digitizer bracket to the chassis in
order to create a stable and robust connection to
chassis ground.
In the absence of such a connection, ATS9626 is not
guaranteed to operate within the specifications listed
elsewhere in this manual.
Some motherboards may have a 16-lane connector, but only
one of the lanes is connected to the motherboard chipset.
Motherboard manufacturers refer to this as “Mechanically
16-lane, electrically 1 lane”. ATS9626 is fully compatible
with such motherboards, but the data throughput across PCI
Express bus will be limited by the number of lanes.

ATS9626 User Manual
Coprocessor FPGA
As shown in the ATS9626 block diagram, all signals to and
from the front panel pass through the Coprocessor FPGA.
The default firmware loaded by the device driver is a “passthrough” FPGA. This way, users who do not wish to
customize the FPGA but do need the fast 16 bit ADC
capability of the ATS9626 can use the product straight out of
the box.
Coprocessor is a Stratix III FPGA from Altera. There are two
FPGA sizes supported:

EP3SL50F780C4N
or

EP3SE260H780C4N
To design a custom Coprocessor FPGA, you must purchase
ATS9626 FPGA Development Kit (ATS-FDK).
For more information on ATS-FDK, please see the FPGA
Development Kit Manual on the ATS9626 product page:

Analog Input
The two analog input channels are referenced to common
ground in bipolar mode. These settings are fixed; therefore,
neither the reference nor the polarity of input channels can be
changed. You cannot use CH A or CH B to make differential
measurements or measure floating signals unless you
subtract the digital waveforms in software.
For accurate measurements, make sure the signal being
measured is referenced to the same ground as your
ATS9626 by attaching the probe’s ground clip to the signal
ground.
The External Trigger input (labeled TRIG IN) has is a LVTTL
Input with an absolute maximum input from -0.7V to +8V.
The CH A and CH B inputs are DC coupled. If you need to
measure ac-coupled signals, you must use external
capacitors to block the dc bias.
Input range of the CH A and CH B inputs is fixed at ±1.25V.
Optionally, it is possible to order ATS9626 with a ±200mV
input range. Note that this option cannot be implemented in
the field.

ATS9626 User Manual
Monolithic 16-bit ADC
ATS9626 uses two monolithic analog-to-digital converters
with a maximum conversion rate of 250 MS/s.
If you use an external clock, you must follow all the timing
specifications on the external clock as described in Appendix
A, Specifications.
Multiple Record Acquisition
The ATS9626 allows the capture of multiple records into the
on-board memory. This allows you to capture rapidly
occurring triggers in OCT, ultrasound or radar applications.
Note that ATS9626 allows you to acquire pre-trigger data.
Specifying Record Length
Record Length is specified in number of sample points. It
must be a minimum of 256 points and can be specified with a
64-sample resolution. If user designs their own Coprocessor
FPGA with its own acquisition manager, these restrictions
can theoretically be overcome.
Specifying Pretrigger Depth
You can acquire pre-trigger data up to the limit of (Record
length – 256). Minimum value for pre-trigger amount is 0. If
user designs their own Coprocessor FPGA with its own
acquisition manager, these restrictions can theoretically be
overcome.
Specifying Record Count
User can specify the number of records that must be
captured into host PC memory. The minimum value must be
1.
The maximum Record Count value in single-port memory
mode is 1000.
In dual-port memory mode, there is no upper limit on how
many records you can capture in one acquisition.
ATS9626 User Manual

External Trigger
ATS9626 allows you to supply a TRIG IN (also known as
External Trigger) signal for triggering purposes.
External Trigger must an LVTTL digital signal, i.e. 0 to 3.3V
TTL signal. Minimum pulse height requirement is 2.0 Volts.
Input impedance of this input is 10 K.
Analog signals and smaller amplitude digital signals will not
be detected as trigger events.
User can select between rising edge and falling edge of this
signal as the trigger event.
It should be noted that the TRIG IN signal passes through the
Coprocessor FPGA. This description of TRIG IN applies to
the default Coprocessor FPGA shipped with ATS9626
drivers. A custom Coprocessor FPGA can completely
change the functionality of this signal.

Calibration
Calibration is the process of minimizing measurement errors
by making small circuit adjustments.
All ATS9626 digitizers are factory calibrated to the levels
indicated in Appendix A, Specifications. Note that AlazarTech
calibration is fully NIST traceable.
However, your digitizer needs to be periodically recalibrated
in order to maintain its specified accuracy. This calibration
due date is listed on the CALIBRATION sticker affixed to your
ATS9626 digitizer.
Externally recalibrate the ATS9626 when this calibration
interval has expired.
This requires three very simple steps:
1. Verify whether or not ATS9626 is still within its
specifications. If it is, then your calibration can be
extended by another one-year period
2. If not, perform calibration, i.e. make adjustments to
the circuit until it is within specifications again
3. If any adjustments have been made, verify if the
ATS9626 is within specifications
Recalibration must be performed at AlazarTech factory.

ATS9626 User Manual
External Clock
ATS9626 allows you to bypass the on-board clock oscillator
and supply your ADC clock. This option is extremely
important in many RF applications in which phase
measurements must be made between the inputs themselves
or between the inputs and an external event.
Another application that requires external clock is Optical
Coherence Tomography (OCT) that sometimes requires
analog sampling to take place relative to an MZI clock,
sometimes also known as k-clock.
Driving high performance ADCs must be done carefully, as
any injection of phase jitter through ADC clocks will result in
reduction in data conversion quality.
Aside from phase noise, the clock signal for a pipelined ADC
must also have a duty cycle close to 50%. This maximizes
the dynamic performance of the ADC. See Fast External
Clock section below for more details.
External clock input impedance is fixed at 50 Ohms.
External clock input is always AC-coupled.
There are three types of External Clock supported by
ATS9626:

Fast External Clock

Slow External Clock

10 MHz Clock Reference
The following paragraphs describe the three types of External
Clock input and outline the restrictions on each of them.
ATS9626 User Manual
35
Fast External Clock
This setting must be used when the external clock frequency
is in the range of 50 MHz to 250 MHz.
It is highly recommended that the Fast External Clock signal
have a duty cycle of 50% +/- 5%. However, duty cycle
specification can be substantially relaxed at lower
frequencies.
If the External Clock supplied is lower than 50 MHz,
measurement quality may be compromised. Measurement
errors may include gain errors, signal discontinuities and
general signal distortion.
If you want to clock slower than the lower limit of Fast
External Clock, you must use the Slow External Clock.
External Clock must be a sine wave or square wave signal
with amplitude in the range of 100 mVp-p to 1 Vp-p.
The receiver circuit for Fast External Clock is a high speed
analog comparator that translates the input signal into a
PECL (Positive ECL) clock signal that features very fast rise
times.
Since Fast External Clock is always ac-coupled and selfbiased, there is no real need for the user to set the external
clock level. However, in some cases of burst mode clocking,
the user may have to adjust this level for optimal operation.
Dummy Clock Switchover is another useful feature for OCT
applications that use Fast External Clock. In these
applications, the user-supplied clock is not of constant
frequency and may even be out of specification at certain
times.
The unique Dummy Clock Switchover capability of ATS9626
allows the sampling clock to be switched to a nominal 100
MHz clock while the user-supplied clock is out of
specification. The amount of time for which the Dummy Clock
remains in operation can be set programmatically by the
user.
36
ATS9626 User Manual
Slow External Clock
This setting must be used when the external clock frequency
is slower than the lower limit of Fast External Clock.
In this range, the input clock is tracked by the 250 MHz
internal clock and a sample is taken on every rising or falling
clock edge. As such, there will be a timing error of 0 to 4
nanoseconds. For low bandwidth signals, this error can be
considered to be negligible.
Slow External Clock signal must be a 3.3 Volt TTL signal with
a minimum pulse height requirement of 2.0 Volts for
guaranteed operation. Signals with smaller amplitudes may
not be detected and may result in corrupted data or failed
triggering.
10 MHz Clock Reference
ATS9626 allows the user to synchronize the sampling clock
to an external 10 MHz reference signal. This is useful in
many RF applications.
Reference clock frequency must be 10 MHz +/- 0.5 MHz.
Amplitude can be a sine or square wave from 100 mVp-p to
1 Vp-p.
It should be noted that the 10 MHz reference produces a 250
MHz clock. Users can set lower sampling frequency by
specifying a decimation value.
ATS9626 User Manual
37
Streaming Data Across the Bus
One of the most unique features of the ATS9626 is its onboard, dual-port acquisition memory that can act as a very
deep Data FIFO and the associated Dual-DMA engine.
This combined by the advanced, fully asynchronous software
driver allows data transfer to host PC memory without any
appreciable “in-process” software involvement.
These features are particularly useful for applications that
require:
a) Continuous, gapless data capture. Also known as Data
Streaming to PC host memory or hard disk
or
b) Data capture from rapidly occurring triggers, also known
as Pulse Repeat Frequency Captures or PRF Captures.
In order to understand these sophisticated features, let us
first review some of the issues involved in transferring data
under Windows or Linux operating systems.
38
ATS9626 User Manual
The Effects of the Operating System
Windows and Linux are not real-time operating systems, i.e.
the operating system cannot guarantee a deterministic
response time to an event, such as an interrupt or a software
generated event.
This means that if software has to play any appreciable part
in data transfer, then the data throughput cannot be
guaranteed, as the operating system will have the last say as
to when the data collection application will get the CPU
cycles to execute the necessary commands.
Note that the above is true even if the digitizer claims to use
Direct Memory Access (DMA) to do the actual transfer, but
uses software commands to re-arm the digitizer. It is the rearm command that will determine the overall data throughput.
For example, it is very common for PCI digitizers that boast
very fast throughput to slow down considerably when
capturing pulsed radar or ultrasonic signals at Pulse Repeat
Frequency (PRF) of 1 KHz or so, even though each capture
is only 2048 bytes (a paltry 2 MB/s throughput).
In other words, digitizers that specify raw data throughput of
100 MB/s can hardly handle 2MB/s effective throughput due
to operating system related delays in issuing re-arm
commands.
ATS9626 User Manual
39
Real-Time Operating Systems
Some vendors claim that switching to a real-time operating
system (RTOS) can solve the problems involved in PRF data
capture.
Before switching to an expensive RTOS (such as VxWorks,
QNX or PharLap ETS), ask the vendor of the operating
system, the supplier of your PC system and manufacturer of
the digitizer board if they are all guaranteed to be 100%
compatible and interoperable with each other with
deterministic interrupt latencies and if you will get your money
back if the system does not work at your PRF rates with your
software.
Here is an excerpt from a FAQ section of one such supplier
of RTOS:
Question: How do system configuration and CPU selection
impact the interrupt latency?
Answer: Hardware platforms and the configuration of the
associated drivers that use the hardware do impact response
times. Some of the common issues include:
Video cards - some of the higher-end cards lock-out (or busywait) the bus for extended periods of time to improve their
performance.
DMA devices - devices which burst DMA for lengthy period.
Power management which cycles off the CPU during IDLE CPU
periods.
Memory speeds, processor speeds, etc.
A PCI or PCI Express digitizer being used in a PRF or
streaming application is, by definition, doing “burst DMA for
lengthy period”, and is a type of product that can negatively
impact response times of the RTOS.
40
ATS9626 User Manual
As such, the claim that an RTOS can remove all timing
uncertainties in PRF application is suspect, to say the least.
Furthermore, you may not be able to get software drivers for
the selected RTOS for all the hardware components you
need for your system.
In summary, moving to a real-time operating system will not
guarantee data throughput, but will surely increase the overall
system cost, increase the cost of software development and
maintenance and limit the number of suppliers for other
hardware components.
Dual Port Memory
The basic throughput problem faced by digitizers is that
almost all of them use single-port memory, i.e. if you are
reading data from the acquisition memory, you cannot
capture into it and vice-versa.
This requires a software handshake which is heavily
dependent on the operating system response time.
ATS9626 User Manual
41
ATS9626 solves this problem by providing dual-port memory
that can act as a very deep FIFO and an advanced dual-DMA
engine that can stream data to PC host memory at up to 1.6
GB/s (exact rate is motherboard dependent).
Bottom line is that software does not have to wait until the
end of data capture to read the acquired data.
42
ATS9626 User Manual
AutoDMA
Just having dual-ported memory or a FIFO, on its own, does
not solve the problem of PRF captures or streaming
applications. Software still has to get involved in re-arming
the hardware after every capture and again for reading the
data from on-board acquisition memory.
ATS9626’s proprietary AutoDMA circuitry allows the
acquisition system to be re-armed by a hardware command
and data transfer to be initiated by the hardware itself, thus
removing virtually all “in-process” software involvement.
ACQUIRE
ACQUIRE
ACQUIRE
TRANSFER
TRANSFER
ACQUIRE
TRANSFER
Of course, software still has to set up the DMA when one of
the buffers fills up, but, thanks to the dual-DMA engine and
fully asynchronous driver that uses overlapped IO, these
tasks can be paralleled.
In other words, when software is re-arming DMA channel 0,
DMA channel 1 is already transferring data to host memory.
Note that if data throughput is too high, a DMA_OVERFLOW
flag gets set and is available to the programmer.
Consumption of the captured data is, of course, under the
control of user-created software, and it is this that will
determine the maximum PRF instead of the bus throughput.
The important thing to note is that if asynchronous DMA is
used, CPU usage is no more than 5%, even if a 1.6 GB/s
DMA is going on.
ATS9626 User Manual
43
Traditional AutoDMA
In order to acquire both pre-trigger and post-trigger data in a
dual-ported memory environment, users can use Traditional
AutoDMA.
Data is returned to the user in buffers, where each buffer can
contain from 1 to 8192 records (triggers). This number is
called RecordsPerBuffer.
Users can also specify that each record should come with its
own header that contains a 40-bit trigger timestamp.
A BUFFER_OVERFLOW flag is asserted if more than 512
buffers have been acquired by the acquisition system, but not
transferred to host PC memory by the AutoDMA engine.
While Traditional AutoDMA can acquire data to PC host
memory at the maximum sustained transfer rate of the
motherboard, a BUFFER_OVERFLOW can occur if more
than 512 triggers occur in very rapid succession, even if all
the on-board memory has not been used up.
44
ATS9626 User Manual
No Pre-Trigger (NPT) AsyncDMA
Many ultrasonic scanning and medical imaging applications
do not need any pre-trigger data: only post-trigger data is
sufficient.
NPT AutoDMA is designed specifically for these applications.
By only storing post-trigger data, the memory bandwidth is
optimized and the entire on-board memory acts like a very
deep FIFO.
Note that a DMA is not started until RecordsPerBuffer
number of records (triggers) have been acquired.
NPT AutoDMA buffers do not include headers, so it is not
possible to get trigger time-stamps.
More importantly, a BUFFER_OVERFLOW flag is asserted
only if the entire on-board memory is used up. This provides
a very substantial improvement over Traditional AutoDMA.
NPT AutoDMA can easily acquire data to PC host memory at
the maximum sustained transfer rate of the motherboard
without causing an overflow.
This is the recommended mode of operation for most
ultrasonic scanning, OCT and medical imaging applications.
ATS9626 User Manual
45
Continuous AsyncDMA
Continuous AutoDMA is also known as the data streaming
mode.
In this mode, data starts streaming across the PCIe bus as
soon as the ATS9626 is armed for acquisition. It is important
to note that triggering is disabled in this mode.
Continuous AutoDMA buffers do not include headers, so it is
not possible to get trigger time-stamps.
A BUFFER_OVERFLOW flag is asserted only if the entire onboard memory is used up.
The amount of data to be captured is controlled by counting
the number of buffers acquired. Acquisition is stopped by an
AbortCapture command.
Continuous AutoDMA can easily acquire data to PC host
memory at the maximum sustained transfer rate of the
motherboard without causing an overflow.
This is the recommended mode for very long signal
recording.
46
ATS9626 User Manual
Triggered Streaming AsyncDMA
Triggered Streaming AutoDMA is virtually the same as
Continuous mode, except the data transfer across the bus is
held off until a trigger event has been detected.
Triggered Streaming AutoDMA buffers do not include
headers, so it is not possible to get trigger time-stamps.
A BUFFER_OVERFLOW flag is asserted only if the entire onboard memory is used up.
As in Continuous mode, the amount of data to be captured is
controlled by counting the number of buffers acquired.
Acquisition is stopped by an AbortCapture command.
Triggered Streaming AutoDMA can easily acquire data to PC
host memory at the maximum sustained transfer rate of the
motherboard without causing an overflow.
This is the recommended mode for RF signal recording that
has to be started at a specific time, e.g. based on a GPS
pulse.

Stream To Disk
Any one of the AutoDMA modes can be combined with a fast
disk drive to create a very efficient and low cost data
streaming system.
AlazarDSO Stream To Disk module (sold separately) allows
out-of-the-box disk streaming. No programming is required.
