General safety summary
Installing single or multiple/independent CompuScope
CompactPCI/PXI cards
In this section, we will go over a simple, step-by-step procedure for installing a single CompactPCI/PXI
CompuScope card in your CompactPCI system.
If you have purchased 2 or more cards for a Multiple/Independent system, simply repeat steps 2 to 7 (inclusively)
as many times as needed to install all of your cards. Note that current versions of GageScope software can
display channels from only one multiple-independent card in the same window. GageScope will automatically
open one separate display window for each enabled CompuScope.
Before installing the CompuScope card, please refer to page 1 for Electrostatic Discharge (ESD) handling
procedures.
1
Power off your CompactPCI chassis.
CompuScope cards are not hot-swappable and all installation and removal must be done with the power
off.
2
Select the required number of unused full-sized 6U CompactPCI expansion slots.
You need one slot for the following cards: CompuScope 82GC; CompuScope 85GC;
CompuScope 14100C-1M; CompuScope 1610C-1M, CompuScope 3200C-2MB.
You will need two slots for the following cards with 8M or more memory: CompuScope 1610C,
CompuScope 14100C, or CompuScope 3200C.
There is no limitation on which slot is used, as the CompuScope card will operate correctly in any slot.
FOR HIGHEST SIGNAL FIDELITY, IT IS RECOMMENDED THAT THE COMPUSCOPE CARD BE
INSTALLED AT LEAST ONE SLOT AWAY FROM A HIGH FREQUENCY NOISE SOURCE, SUCH AS
A POWER SUPPLY OR CPU CARD.

Installing CompactPCI/PXI Master/Slave multi-card systems
Multiple Record for CompuScope 14100C and CompuScope 1610C
Please note: the CompuScope 85GC and CompuScope 3200C do not support Multiple Record.
See next page for details on Multiple Record for the CompuScope 82G.
Even though the CompactPCI bus allows very fast data throughput to system RAM, there may still be
applications in which data bursts cannot be off-loaded either because of very fast trigger repeat frequency or
because of software limitations.
Multiple Recording allows the CompuScope card to capture data on successive triggers and stack it in the onboard memory.
It should be noted that only post-trigger data can be captured in Multiple Record mode.
GageScope software can display the stacked data as individual acquisitions. Software drivers also provide
support for accessing Multiple Record data.
Once the CompuScope card has finished capturing a Multiple Record segment, the trigger circuitry is
automatically re-armed within 16 sample clock cycles to start looking for the next trigger. No software
intervention is required.
Figure 14: Multiple Record mode
Multiple Recording is useful for applications in which a series of bursts of data have to be captured in quick
succession and there is not enough time to off-load the data to the system RAM.
Another situation in which Multiple Recording may be used is when data storage has to be optimized. These are
cases in which only certain portions of the incoming signal are of interest and data capture during the dead time
between successive portions is not useful.
Examples of these situations are radar pulses, ultrasound data, lightning pulses, imaging signals and explosion
testing.
Multiple Record for CS14100C & CS1610C
19
Multiple Record for the CompuScope 82GC
Even though the CompactPCI bus allows very fast data throughput to system RAM, there may still be
applications in which data bursts cannot be off-loaded either because of very fast trigger repeat frequency or
because of software limitations.
Multiple Recording allows CompuScope 82GC to capture data on successive triggers and stack it in the on-board
memory. The minimum record size is 256 samples in dual channel mode and 512 samples in single channel
mode. CompuScope 82GC models with 16M acquisition memory provide up to 21,845 records which can be
captured in Multiple Record mode.
The CompuScope 82GC is capable of capturing pre-trigger data in Multiple Record mode. Software can
configure the CompuScope 82GC to capture between 0 to 32K points of pre-trigger data.
GageScope software can display the stacked data as individual acquisitions. Software drivers also provide
support for accessing Multiple Record data.
Once the CompuScope 82GC has finished capturing a Multiple Record segment, the trigger circuitry is
automatically re-armed within 152 (304) sample clock cycles in dual (single) channel mode to start looking for
the next trigger. No software intervention is required. This is required to ensure that the necessary pre-trigger
data is acquired. That is, data is acquired during this time, however, the trigger is only enabled once the
pre-trigger data has been recorded.
Figure 15: Multiple Record mode with Pre-Trigger data
Multiple Recording is useful for applications in which a series of bursts of data have to be captured in quick
succession and there is not enough time to off-load the data to the system RAM.
Another situation in which Multiple Recording may be used is when data storage has to be optimized. These are
cases in which only certain portions of the incoming signal are of interest and data capture during the dead time
between successive portions is not useful.
Examples of these situations are radar pulses, ultrasound data, lightning pulses, imaging signals and explosion
testing.

Multiple Record for CS82GC
Memory organization on CompuScopes (except for the CS85GC)
Please note: for memory organization on the CompuScope 85GC, please refer to the next section.
Memory architecture
CompuScope cards have high-speed on-board memory to store the digital data for the CompactPCITM bus to
access it in post-processing mode.
Interface to the CompactPCITM bus
In order to allow optimum data transfer rates from the CompuScope card memory to the PC memory, the
on-board RAM is mapped into the memory space of the CompactPCITM bus.
The exact address at which this memory is mapped is determined by the CompactPCITM Plug-n-Play BIOS. This
means that the user does not have to set any jumpers or switches to configure the CompuScope card—it really is
plug and play.
Bus Mastering mode
Full Bus Mastering capabilities are provided on CompuScope cards, allowing the fast data transfer to occur as a
result of a Direct Memory Access (DMA).
Software loads the start address, destination pointer and number of points to be transferred into the
CompactPCITM bus controller on the CompuScope card and then asks the card to do a DMA transfer. The
CompactPCITM bus mastering control circuitry takes over from this point and performs the transfer without any
CPU involvement.
Data storage
The data coming out of the A/D converters or digital input is stored in the on-board memory buffer, which is
configured as a circular buffer. A circular buffer is used to guarantee that the system will keep on capturing data
indefinitely until a trigger event is detected.
The sequence of events is as follows:
• CompactPCITM bus tells the CompuScope to start_capture using a register bit.
•
The CompuScope sets BUSY flag. CompactPCITM bus is denied any further access to the on-board
memory.
•
The on-board memory counters initialize to ZERO and start counting up, thereby starting data storage at
memory address ZERO.
•
The system waits for a trigger event to occur while it is storing data in the on-board memory. This data is
called Pre-Trigger data.
•
Once the trigger event is received, a specified number of Post-Trigger points are captured. The number of
Post-Trigger Points can be specified by writing to a register on the CompuScope.
•
After storing the specified number of Post-Trigger Points subsequent to receiving the trigger event,
acquisition is stopped, BUSY flag is reset and PC bus is allowed access to the on-board memory.
Memory organization on CompuScopes (except for CS85GC)
21
A graphical representation of the above sequence is as follows:
Figure 16: Pre-Trigger: all data points in buffer valid
In the diagram above, the circular memory buffer is shown as a ring with the physical memory address ZERO at
the top. Data storage is shown as a spiraling line going clockwise.
Storage starts at address ZERO and keeps on writing into the memory until it is filled (the spiraling line
completes a circle) and then starts overwriting the data stored in addresses ZERO, 1, 2...
Once a trigger event is detected, the address to which the data was being written into is tagged as the Trigger
Address, a specified number of Post-Trigger points are captured and then the acquisition is stopped.
The memory address at which the acquisition is stopped is designated as the End Address and the address after
that one is called Start Address.
Now, Pre-Trigger data lies between Start Address and Trigger Address, and Post-Trigger data between Trigger
Address and End Address.
It is clear from the diagram shown above that memory address ZERO is not necessarily the first point, or Start
Address, of the signal being captured. In fact, the physical address ZERO has very little significance in such a
system, as the trigger can happen at any time.
One case in which ZERO is the Start Address is when a trigger is received before the memory had filled up, i.e.
the trigger was received right after the software tells the CompuScope to start_capture.
22
Memory organization on CompuScopes (except for CS85GC)
This situation is illustrated below:
Figure 17: Pre-Trigger: not all data points in buffer valid
This condition can be detected by looking at the RAMFULL bit in the STATUS register. This bit is reset to
ZERO when a start_capture command is issued and is set to ONE when the memory counters overflow from
FFFFF to ZERO, for example.
In this case, Pre-Trigger data lies between ZERO and Trigger Address, and Post-Trigger between Trigger
Address and End Address.
These issues are handled seamlessly by the driver and the Software Development Kits (SDKs).

Memory organization on CompuScope 85GC
FISO memory architecture
CompuScope 85GC uses a very unique memory system that uses on-chip analog memory cells that can store the
instantaneous value of the input voltage at a particular time.
By using 10,000 such cells for each of the input channels, CompuScope 85GC can offer acquisition depth of
10,000 points per channel.
This “analog storage data” is then converted to digital codes using a very accurate, but slower speed A/D
converter to yield very fast sampling speed at an unprecedented price.
Hence the name, Fast In Slow Out.
On-board error correction and calibration
Not surprisingly, the analog memory cells on the CompuScope 85GC are not absolutely accurate from one
device to another. As such, it is necessary for each CompuScope 85GC to be calibrated.
All error correction and calibration is performed by very powerful signal processors, including custom ASICs,
on-board the CompuScope 85GC.
Interface to the CompactPCITM bus
In order to allow optimum data transfer rates from the CompuScope 85GC acquisition memory to the PC
memory, the on-board circuitry uses DMA to move the data from the memory of the on-board calibration
processors into PCI memory.
CompactPCITM Plug-n-Play BIOS is fully supported by CompuScope 85GC, making it unnecessary for the user
to worry about setting any jumpers or switches to configure the CS85GC.
A/D data storage
FISO memories are configured as circular buffers. A circular buffer is used to guarantee that the system will keep
on capturing data indefinitely until a trigger event is detected.
The sequence of events is as follows:
• CompactPCITM bus tells the CompuScope to start_capture using a register bit.
• BUSY flag is set by the CompuScope. CompactPCITM bus is denied any further access to the on-board
memory.
• The on-board FISO memory counters initialize to ZERO and start counting up, thereby starting data storage
at memory address ZERO.
• The system waits for a trigger event to occur while it is storing data in the on-board memory. This data is
called Pre-Trigger data.
• Once the trigger event is received, a specified number of Post-Trigger points are captured. The number of
Post-Trigger Points can be specified by writing to a register on the CompuScope.
• After storing the specified number of Post-Trigger Points subsequent to receiving the trigger event,
acquisition is stopped, BUSY flag is reset and PC bus is allowed access to the on-board memory.

25
A graphical representation of the above sequence is as follows:
Figure 18: Pre-Trigger: all data points in buffer valid
In the diagram above, the circular memory buffer is shown as an annulus with the physical memory address
ZERO at the top. Data storage is shown as a spiraling line going clockwise.
Storage starts at address ZERO and keeps on writing into the memory until it is filled (the spiraling line
completes a circle) and then starts overwriting the data stored in addresses ZERO, 1, 2...
Once a trigger event is detected, the address to which the data was being written into is tagged as the Trigger
Address, a specified number of Post-Trigger points are captured and then the acquisition is stopped.
The memory address at which the acquisition is stopped is designated as the End Address and the address after

Now, Pre-Trigger data lies between Start Address and Trigger Address, and Post-Trigger data between Trigger
Address and End Address.
It is clear from the diagram shown above that memory address ZERO is not necessarily the first point, or Start

Driver installation guide
Installing your Gage hardware in a computer is only one step in setting up your system. You also need to install
drivers and application software to operate the instrument card or cards you purchased. This section will
describe how to install software and verify the operation of your new hardware.
Please note that due to the various versions of operating systems supported by Gage, the screen captures serving
as illustrations in this manual may differ from what you will see on your screen. The discrepancies will not be
material when it comes to basic functionalities and operation; however, the look and certain names will be
slightly different.
Driver installation guide
27
Section 1 – Installing drivers and applications
The product you bought comes with a totally re-designed and vastly improved installation package. This new
installer was designed to work the same way on all supported operating systems. It was also designed to be
intuitive to most users and easy to follow for anyone familiar with installing software on a computer running
Windows. Therefore a certain level of familiarity with the Windows operating system is assumed in this manual.
The basic instructions presented in this section should be sufficient for most installation needs.
The main installation steps are as follows: (you may skip some of the steps if you do not wish or need to install
certain drivers or applications)
A – If you have not already done so, insert your Gage Software CD into the CD-ROM drive of your computer.
The AutoRun feature of Windows should kick-in and bring up the installer’s main screen. If this does not take
place, you can start the installer by double-clicking on the gage.exe item that you will find on the CD.
The Gage software disk main screen will appear (see Figure 19 below).
Figure 19: The Gage Software Disk’s main screen
This window offers four possible options (not counting the Exit option):
• Install Software
• Browse CD
• Contact Gage
• About CD
The fourth option, About CD, is an important first step whenever troubleshooting the installation or asking for
technical support from Gage. It provides valuable information about the various software drivers and application

Section 2 – Verifying the operation of your hardware
Verifying installation and configuration of CompuScope hardware under
Windows 2000/XP with CompuScope Manager
If you wish to verify installation and configuration of your CompuScope cards under Windows 98/ME/NT,
please refer to the next section: Verifying installation and configuration of CompuScope hardware under
Windows 98/ME/NT with GageConfig.
The CompuScope Manager utility is used to verify the configuration your CompuScope cards under
Windows 2000/XP.
The CompuScope Manager utility is installed at the same time as the CompuScope 3.82 drivers. You can access
the CompuScope Manager from the Gage folder in the Programs category of the Start Menu of Windows.
The main screen of the CompuScope Manager is the Resource Manager tab (see Figure 50 below):
Figure 50: Card information from the Resource Manager tab of the CompuScope Manager
This screen provides you information about the Gage card or cards installed in your system. You can see the
type of card, the number of cards in the system, the number of channels on the card, the nominal resolution of the
card, the on-board memory, whether the card is active or inactive, and even the handle that the system has to
control the card from software (through the driver).
52
Driver installation guide
Verifying installation and configuration of CompuScope hardware under
Windows 98/ME/NT with GageConfig
GageConfig is used to verify the configuration your CompuScope cards under Windows 98/ME/NT.
The GageConfig Manager utility is installed at the same time as the drivers and you do not need to do anything
special to get it. You can access GageConfig from the Gage folder in the Programs category of the Start Menu
of Windows.
Figure 51: GageConfig screen
GageConfig creates a binary file called GAGESCOP.INC that contains the information necessary for the driver
to recognize the CompuScope card(s). This file is kept in the Windows\System folder of your computer.
Please note that the CompuScope cards are plug-and-play devices, so you do not need to specify an I/O or a
memory address, as you would have had to for ISA products.
It is, however, necessary to declare the I/O and Memory addresses as “PnP” in the appropriate section of
GageConfig. This would tell GageConfig that we are trying to locate a Plug-n-Play device.
If I/O and Memory Base addresses are not specified to “PnP”, GageConfig will not recognize your CompuScope
card.
If you require more information on how to use GageConfig, you can download a manual from the Gage website
http://www.gage-applied.com/support/softwares.php (click on Download Utilities).

53
Verifying signal acquisition of a CompuScope card with GageScope and CSTest
Gage strongly recommends that you become familiar with GageScope as a powerful tool for capturing and
analyzing signals, even if you will eventually develop your own application to control your hardware. Since it
embodies all the knowledge required to operate the wide array of CompuScope cards and all their functionalities,
GageScope is the ideal tool to verify the operation of your hardware and to troubleshoot applications you may
develop on your own. GageScope Lite is provided for free to all users of CompuScope cards for precisely this
purpose.
You can find extremely detailed instructions on how to use GageScope in the GageScope manual that is included
in PDF format on the Gage Software Disk (CD Drive:/Gage/SW Manuals).
However, if you have not already installed GageScope, or if you do not wish to install it at this point, Gage
provides a simple application, CSTest+ for CompuScope 3.82 drivers (or CSTest for CompuScope 3.60 drivers)
that allows you to capture signals and verify the correct operation of your new CompuScope card. Note that the
following section details the CSTest+ functionality only, but CSTest has a slightly different interface.
54
Driver installation guide
Section 3 – Verifying signal acquisition with CSTest+
CSTest+ is a utility program that allows acquisition and display of data from a CompuScope card using
CompuScope 3.82 drivers. It acts as a test to ensure that your CompuScope card(s) is fully functional.
Now that you have successfully installed the CompuScope drivers and have tested driver installation with the
CompuScope Manager utility, you can run CSTest+ to verify that these drivers are properly communicating with
your CompuScope card(s).
Setting-up your Hardware
Using a function (signal) generator, generate a 1 MHz sine wave signal and connect it to the CH1 input of your
CompuScope card. If you have installed a CompuScope 8500 card, use the 1 MΩ input instead.
Running CSTest+
You can run CSTest+ from the Windows Start Menu:
Driver installation guide
55
If there is more than one acquisition system installed on the same computer, you should see the Select System
dialog pop-up. Select the acquisition system you want to test then click OK. You will not see this dialog if there
is only one acquisition system installed in the computer.
You should now see a window labeled CsTest +. You can view the sine wave that you have generated using the
function generator that you have previously connected by selecting Acquire from the Controls menu:
To view the sine wave continuously in time, go to the Controls menu and click on Continuous. Note that the
sine wave on the screen starts from the positive slope. As you change the frequency of the sine wave on your
function generator, you will see a corresponding change in the sine wave displayed in CSTest+.
Note: You may have noticed the four-digit number in the bottom left corner of the CSTest+ window. This is a
counter. Every time CSTest+ acquires data, the counter is incremented by 1.
On the right of the counter is the acquisition status. The acquisition status can be one of the following:
Ready
Waiting For Trigger
Triggered…
Data Transfer…
56
Ready for another data acquisition.
Data acquisition is in progress, the trigger condition has not been met.
Data acquisition is in progress.
Data transfer from on-board memory to PC memory is in progress.
Driver installation guide
Now, go back to the Controls menu and click on Abort. This will stop any further acquisition.
We will now change a trigger parameter such as Trigger Slope to verify that all controls for the card are
working as they should. Go to the Parameters menu and select Trigger Config.
Driver installation guide
57
You should see a new dialog box: (Depending on the version of drivers you have installed, the dialog may look
slightly different)
Click on the radio button next to Negative in the Trigger Slope panel to change the trigger slope from positive
to negative. Click on OK for this change to be registered and to close the dialog box.
When you go back to the Controls menu and click on Continuous, you should see the same sine wave, but
starting from a negative slope.
This short experiment proves that communication between a utility program, CSTest+, the CompuScope drivers
and a CompuScope card has been successfully established. The following screens describe the other
functionalities available with CSTest+:

CompuScope 85GC product introduction
CompuScope 85GC is the world’s fastest CompactPCITM waveform digitizer, capable of sampling two
simultaneous input channels at rates as fast as 5 GS/s with 8 bit vertical resolution.
Recognizing that until very recently, almost all multi-MegaHertz data acquisition was done using Digital Storage
Oscilloscopes under GPIB control, Gage has ported all the features of these DSOs onto the CompuScope card.
This means that you do not have to rethink the solution in terms of a completely unknown data acquisition card.
You can simply develop the data acquisition system as if an oscilloscope were being used, but instead use a
CompuScope card to take advantage of its attractive price and performance.
Of course, CompuScope cards are much more than just another DSO under GPIB control:
•
Data transfer rates from CompuScope memory to PC memory or extended memory run at least 100 times
faster than a GPIB-DSO combination
•
CompuScope cards are easier to program, as Software Development Kits (SDKs) are available for C/C++,
MATLAB, LabVIEW and LabWindows/CVI.
•
In case you do not want to program the CompuScope 85G, you can use the powerful GageScope®
oscilloscope software to acquire, analyze and archive signals.
•
CompuScope cards are installed inside the CompactPCITM chassis, so there is no external box such as a
DSO.

CompuScope 85GC: identifying your CompuScope card(s)
Your CompuScope 85GC card is composed of the CS85GC base board and the CS85GC analog board.
You will find your CompuScope 85GC card type and version as shown in Figure 53: CS85GC labels, card type
& hardware version number. Figure 53 also shows the location of the Calibration label.
The Calibration label lists your CompuScope card’s serial numbers. You should record these serial numbers for
future reference on the technical support form found at the front of this guide.

CompuScope 85GC
CompuScope 85GC connectors and headers
CompuScope cards connect to the outside world through connectors, both analog (BNC) and digital
(CompactPCI Bus). This section describes these connectors for the CS85GC card.
The connectors and headers on the CS85GC card are shown below:
Figure 54: Connectors on CS85GC
•
CH 1 BNC connector is the single-ended input of channel 1 that is used to input an analog signal that is
sampled as Channel 1.
•
CH 2 BNC connector is the single-ended input of channel 2 that is used to input an analog signal that is
sampled as Channel 2.
•
External Trigger BNC connector is used to input an analog or digital signal, which may be used as an
External Trigger. External Trigger is defined exactly as in an oscilloscope: this signal can be used to
trigger the system but cannot be viewed or digitized.
•
CompactPCITM connector is located at the rear of the card. This is an industry standard connector
that complies with all specifications of the CompactPCITM bus.
CompuScope 85GC
81
CompuScope 85GC triggering
CompuScope 85GC features state-of-the-art triggering.
The trigger circuit is identical to that of an oscilloscope. This way, a user can easily replace the Digital
Oscilloscope in his or her application with a CompuScope 85GC. A user can select the trigger source, trigger
level and trigger slope using software commands.
The user can software-select the trigger source from any one of the following:
•
•
•
•
Channel 1
Channel 2
External Trigger
Software Trigger
The selected trigger source is then compared to a trigger level set by an on-board DAC. An on-board, highspeed comparator is used for this function, making it possible to trigger on narrow pulses or glitches that are
much shorter than the sample rate.
Each time the selected signal crosses the trigger level, the on-board triggering circuitry monitors it for the slope
selected by the user. When the appropriate slope is detected, a Trigger signal is generated.
Figure 55: Generation of a trigger signal
External Trigger amplifier
The External Trigger input also has oscilloscope-like 1 MΩ / 20 pF input impedance.
Gage’s proprietary input-protection circuitry allows the FET stage to withstand voltages as high as ±15 Volts
without causing any damage to the inputs.
Software-selectable attenuation of X1 or X5 on the External Trigger input allows input ranges of ±800 mVolt
and ±8 Volt, respectively.
TV Triggering
The CompuScope 85GC provides a TV triggering mode so that it may be triggered off of standard TV signals.
TV signal protocols supported are NTSC and PAL.
CompuScope 85GC allows triggering off of even or odd signal fields or off of any horizontal line which is
specified by a line number.
82
CompuScope 85GC
CompuScope 85GC throughput & maximum PRF
A number of applications require the CompuScope 85GC to acquire data based on a rapidly occurring trigger
signal. These high Pulse Repeat Frequency (PRF) applications include imaging, radar, ultrasound and lightning
test.
The following test results were obtained using a computer configured as follows:
• Pentium III, 850 MHz processor
• 256 MB RAM
• 20 GB disk drive
• Windows 98
• 33 MHz, 32 bit CompactPCITM bus
• All slots support bus mastering
A C application program optimized for fast repetitive capture was used for throughput measurements.
The PRF rates shown below are for dual channel data acquisition, but data is being read out of the card from
only CH 1.
Figure 56: Maximum PRF vs. acquisition length
Notice that a PRF of about 100 Hz can be obtained for all possible capture depths.

CompuScope 82GC product introduction
CompuScope 82GC is an 8 Bit, waveform digitizer card for the CompactPCITM Bus, capable of 2 GS/s sampling
on one channel and 1 GS/s sampling on two simultaneous channels.
Recognizing that until very recently, almost all multi-MegaHertz data acquisition was done using Digital Storage
Oscilloscopes under GPIB control, Gage has ported all the features of these DSOs onto the CompuScope card.
This means that you do not have to rethink the solution in terms of a completely unknown data acquisition card.
You can simply develop the data acquisition system as if an oscilloscope were being used, but instead use a
CompuScope card to take advantage of its attractive price and performance.
Of course, CompuScope cards are much more than just another DSO under GPIB control:
•
CS82GC features deep acquisition memory of up to 16 MB.
•
Multi-card Master/Slave systems provide scalability from 2 to 4 channels of simultaneous A/D conversion.
•
Data transfer rates from CompuScope memory to PC memory or extended memory run as high as 80 MB/s
for the CS82GC as compared to a few hundred KB/s for GPIB.
•
CompuScope cards are easier to program, as Software Development Kits (SDKs) are available for C/C++,
MATLAB, LabVIEW and LabWindows/CVI.
•
CompuScope cards are installed inside the CompactPCITM chassis, so there is no external box such as a
DSO.
•
The CS82GC cards have Pre-Trigger Multiple Record as a standard feature, which helps optimize the use of
the on-board memory by stacking data from successive bursts.
•
You can also write software for a multi-card system in which all the cards are not in a Master/Slave
configuration. Drivers supplied by Gage support all these multi-card configurations.
•
In case you do not want to program the CompuScope 82GC card(s), you can use the powerful GageScope®
oscilloscope software to acquire, analyze and archive signals.
Special features on the CompuScope 82GC include:
•
Bus Mastering
CompuScope 82GC is fully capable of becoming a bus master in order to transfer data at the maximum rate
of 80 MB/s.
A bus Master is a card that can take control of the bus and transfer data to any PCI target device such as
system RAM without any involvement from the CPU.
•
External Clocking
CompuScope 82GC comes standard with external clocking capability that allows synchronization of the
digitizers with an external reference clock.
•
Trigger Output
CompuScope 82GC provides a TTL output on one of the front panel connectors. The rising edge of this
output signifies that a trigger event has been detected on the CompuScope 82GC.
•
Pre-Trigger Multiple Record
Pre-Trigger Multiple Recording allows CompuScope 82G to collect pre-trigger data when the card is in
Multiple Record mode. Up to 32 K points can be captured as pre-trigger data.

CompuScope 82GC: identifying your CompuScope card(s)
Your CompuScope 82GC card is composed of the CS82GC base board and the CS82GC analog board.
You will find your CompuScope 82GC card type and version as shown in Figure 58 and Figure 59. Figure 58
also shows the location of the Calibration label. The Calibration label lists your CompuScope card’s serial
numbers. You should record these serial numbers for future reference on the technical support form found at the
front of this guide.
You may also see an “OPTION/MOD” label listing any upgrades or modifications that have been performed on
your card. For example, if you have purchased a CompuScope 82GC-8M card, the “OPTION/MOD” label will
list “8M” as an option.
Figure 58: CS82GC labels

Figure 59: CS82GC hardware version number
If you have purchased a multi-card system, you will notice that input channel connectors on one card are
numbered “CH 1” & “CH 2” and the other “CH 3” & “CH 4”.
The MASTER card is labeled “CH 1” & “CH 2” and the SLAVE card is labeled “CH 3” & “CH 4”.

CompuScope 82GC connectors and headers
CompuScope cards connect to the outside world through connectors, both analog (BNC) and digital
(CompactPCI Bus, Master/Slave, etc.). This section describes these connectors for the CS82GC card.
The connectors and headers on the CS82GC card are shown below:
Figure 61: Connectors on CS82GC
98
•
CH 1 BNC connector is the single-ended input of channel 1 that is used to input an analog signal that is
sampled as Channel 1.
•
CH 2 BNC connector is the single-ended input of channel 2 that is used to input an analog signal that is
sampled as Channel 2.
•
External Trigger BNC connector is used to input an analog or digital signal, which may be used as an
External Trigger. External Trigger is defined exactly as in an oscilloscope: this signal can be used to
trigger the system but cannot be viewed or digitized.
•
External Clock SMA connector is located on the front panel. This input can be used for injecting a
specific clock signal for digitizing the analog inputs. See the section CompuScope 82GC External
Clock for more details.
•
Master/Slave connector is located on the front panel. This connector is used to pass Clock, Trigger
and Initialization signals from a Master card to Slave card using a Master/Slave Timing Module.
•
Trigger Out BNC connector is located on the front panel near the bottom of the card. This connector
outputs a TTL signal, the low to high transition of which signifies the occurrence of a trigger event on
the CS82GC. See the section CompuScope 82GC Trigger Output for more details.
CompuScope 82GC
•
CompactPCITM connector is located at the rear of the card. This is an industry standard connector
that complies with all specifications of the CompactPCITM bus.
•
Status LEDs are located at the bottom of the front panel. Note that the BUSY LED is illuminated
when the CompuScope 82GC is capturing a signal. The TRIG LED is illuminated after the
CompuScope 82GC receives a trigger.

CompuScope 82GC triggering
CompuScope 82GC features state-of-the-art triggering.
An analog comparator provides triggering from either one of the input channels, or from an external signal or
from software.
In addition to the trigger source, trigger level and slope are also selectable by software, making the trigger
system similar to traditional oscilloscopes.
The user can software-select the trigger source from any one of the following:
•
•
•
•
Channel 1
Channel 2
External Trigger
Software Trigger
The selected trigger source is then compared to a trigger level set by an on-board, 8 bit software-controlled
DAC. An on-board, high-speed comparator is used for this function, making it possible to trigger on narrow
pulses or glitches that are much shorter than the sample rate, subject to the 300 MHz bandwidth limitation of the
front-end trigger circuitry.
Each time the selected signal crosses the trigger level, the on-board triggering circuitry monitors it for the slope
selected by the user. When the appropriate slope is detected, a Trigger signal is generated.
Figure 62: Generation of a trigger signal – negative slope
External Trigger amplifier
The External Trigger input also has oscilloscope-like 1 MΩ / 25 pF input impedance.
Gage’s proprietary input-protection circuitry allows the FET stage to withstand voltages as high as ±15 Volts
without causing any damage to the inputs.
The trigger comparator has an operating range of ±1 Volt.
Software-selectable attenuation of X1 or X5 on the External Trigger input allows input ranges of ±1 Volt and ±5
Volt, respectively.

CompuScope 82GC
CompuScope 82GC External Clock
External clocking is a very powerful feature in a digitizer. It allows the user to synchronize the digitizer to an
external system.
On the CompuScope 82GC, external clock signal must be a continuous sine wave signal of amplitude between
225 mV RMS and 500 mV RMS. Note that the external clock input is AC coupled, so DC biases get canceled.
The allowable external clock frequency is between 1 GHz and 10 MHz. An SMA connector is employed for the
External Clock input because of its superior high frequency response at 1 GHz – BNC connectors start running
into bandwidth limitations at such high frequencies.
PLEASE NOTE:
THE EXTERNAL CLOCK ILLUSTRATIONS IN THIS SECTION DEPICT THE CLOCK SIGNAL
AS A SQUARE WAVE FOR CLARITY, PLEASE FOLLOW THE RECOMMENDATIONS ABOVE
TO ACHIEVE PROPER OPERATION.
In single channel mode, sampling is done on both the “rising” and “falling” edge of the sine wave.
Figure 63: External Clocking in single channel mode
In dual channel mode, sampling is done on only the “rising” edge of the sine wave.
Figure 64: External Clocking in dual channel mode
Note that high-speed waveform digitizers are very sensitive to phase noise and duty cycle of the external clock
input. All efforts should be made to minimize jitter and distortion on the external clock signal.
Care should be taken not to inject a TTL or CMOS signal (0 to 5 Volts) into the external clock input, as it may
result in saturation of the input circuitry.
CompuScope 82GC
101
CompuScope 82GC Trigger Output
A Trigger signal is used to synchronize different parts of a measurement system to the same event.
CompuScope 82GC provides a TTL output on one of the front panel connectors. The rising edge of this output
signifies that a trigger event has been detected on the CompuScope 82GC.
In a Master/Slave configuration, only the Trigger Output of the Master card should be used.
For best results, this output should be terminated with a 50 Ω load capable of absorbing 0.5 Watt power. There
is no output short protection on this signal, so care should be taken in not interfacing it to any output, be it
Ground or any other voltage.
This TTL output is always asserted after a well defined latency inherent in the trigger circuitry. The table shown
below lists the latency for each of the sample rates that the user may select.

It should be noted that Trigger Output is synchronized to an internal clock, called GCLK, on the
CompuScope 82GC. This clock is not the same as the sampling clock.
The relationship between GCLK and sampling clock must be understood in order to take full advantage of this
powerful feature.
102
CompuScope 82GC
Single channel mode
In single channel mode, GCLK is always one-sixteenth the frequency of the sampling clock.
Consequently, Trigger Out signal will be activated after any one of the sixteen rising edges of the sampling clock
after the trigger latency has expired.
Figure 65: Trigger Out in single channel mode
Dual channel mode
In dual channel mode, GCLK is always one-eighth the frequency of the sampling clock.
Consequently, Trigger Out signal will be activated after any one of the eight subsequent rising edges of the
sampling clock after the trigger latency has expired.

CompuScope 82GC - 1 GHz Bandwidth version
The CompuScope 82GC – 1 GHz is a special member of Gage’s high-performance CS82GC product family.
This section explains the key differences between the standard CS82GC and the special 1 GHz bandwidth
version.
1.
Why is 1 GHz of bandwidth important?
A higher bandwidth increases the precision and widens the range of applications of fast digitizers. By
‘precision’ we mean “less distortion” of the high frequency components that can be found in the spectrum of
very fast transients.
While operating at 2 GS/s, the CompuScope 82GC – 1 GHz provides a bandwidth limit that is equal to the
Nyquist frequency of 1 GHz.
2.
Specifications of the CS82GC – 1GHz Bandwidth version
The 1GHz bandwidth version of the CS82GC shares most of the specifications of the standard product.
However, a few key differences exist. This section will highlight these differences and describe how to best
operate the product so as to perform accurate measurements and prevent damage to the card.
Note that the CS82GC – 1 GHz can be ordered with or without Internal Triggering. Only the dynamic
performance of the product is affected by this choice.
2.1 – Input Characteristics and Protection
The modification made to the CS82GC to give it a 1GHz bandwidth requires the bypassing of most of
the protection from high voltages as well as of all but 1 input range in each of the operating modes.
The input must be single-ended with an impedance of 50 Ohms, which is protected by diode clamping.
Therefore, when operating a CS82GC – 1 GHz, users must be cautious to not exceed the absolute
maximum input voltage of ± 1V.
Furthermore, the only input ranges available for this product are ± 250mV in Dual Channel Mode, and
± 500mV in Single Channel Mode.
The following table provides the typical bandwidth of the CompuScope 82GC – 1 GHz with, and
without, Internal Trigger.

Software considerations
Users of the CS82GC – 1 GHz under Windows 98/ME/NT require a special driver version (3.60.30), which
is supplied on the Gage Software Disk. Please note that the CompuScope 3.60.30 driver is a special release
and is not available through the standard install procedure. Instructions on locating the CompuScope
3.60.30 driver can be found in the Gage Software Disk readme, in the section titled: “Which CompuScope
drivers should be installed”.
Users of the CS82GC – 1 GHz under Windows 2000/XP can use the most recent CompuScope Win 2K/XP
drivers.
GageScope® and the various SDKs, however, will not perceive the 1GHz version of the CS82GC as having
only 2 input ranges (one for Dual Channel Mode, one for Single Channel Mode). Users must therefore
ensure that they request the correct input ranges when operating the card, or risk seeing their data scaled by
the wrong factors (see Section 2 on previous page).

CompuScope 82GC throughput & maximum PRF
A number of applications require the CompuScope 82GC to acquire data based on a rapidly occurring trigger
signal. These high Pulse Repeat Frequency (PRF) applications include imaging, radar, ultrasound and lightning
test.
Gage has performed extensive repetitive capture benchmarks in single record mode. In this mode, the signal is
captured into on-board CompuScope memory and the captured data are transferred through the PCI bus using
PCI bus mastering to PC RAM.
Please note that much higher PRFs will be achieved using CompuScope Multiple Record mode.
The following test results were obtained using a computer configured as follows:
• Pentium III, 850 MHz processor
• 256 MB RAM
• 20 GB disk drive
• Windows 98
• 33 MHz, 32 bit CompactPCITM bus
• All slots support bus mastering
A C application program optimized for fast repetitive capture in single record mode was used for throughput
measurements. The CS82GC was operated using this application in both single and dual channel mode for many
different capture depths and the results are plotted as points in the graph below. The PCI transfer rates were
calculated from the linear portion of the curves at high depths.

CompuScope 14100C
CompuScope 14100C product introduction
CompuScope 14100C is a 14 Bit, 100 MS/s data acquisition card for the CompactPCITM Bus, capable of
sampling one channel at 100 MS/s and two simultaneous channels at 50 MS/s.
Recognizing that until very recently, almost all multi-MegaHertz data acquisition was done using Digital Storage
Oscilloscopes under GPIB control, Gage has ported all the features of these DSOs onto the CompuScope card.
This means that you do not have to rethink the solution in terms of a completely unknown data acquisition card.
You can simply develop the data acquisition system as if an oscilloscope were being used, but instead use a
CompuScope card to take advantage of its attractive price and performance.
Of course, CompuScope cards are much more than just another DSO under GPIB control:
•
CS14100C features 14 bit vertical resolution as opposed to the 8 bit resolution offered by DSOs.
•
Multi-card Master/Slave systems provide from 2 to 12 channels of simultaneous A/D conversion, something
normal DSOs simply cannot do.
•
Data transfer rates from CompuScope memory to PC memory or extended memory run as high as 80 MB/s
for the CS14100C as compared to a few hundred KB/s for GPIB.
•
CompuScope cards are easier to program, as Software Development Kits (SDKs) are available for C/C++,
MATLAB, LabVIEW and LabWindows/CVI.
•
CompuScope cards are installed inside the CompactPCITM chassis, so there is no external box such as a
DSO.
•
The CS14100C cards have standard features such as Multiple Record, which help optimize the use of the
on-board memory by stacking data from successive bursts.
•
You can also write software for a multi-card system in which all the cards are not in a Master/Slave
configuration. Drivers supplied by Gage support all these multi-card configurations.
Special features on the CompuScope 14100C include:
•
Bus Mastering
CompuScope 14100C is fully capable of becoming a bus master in order to transfer data at the maximum
rate of 80 MB/s.
A bus Master is a card that can take control of the bus and transfer data to any PCI target device such as
system RAM without any involvement from the CPU.
•
External Clocking
CompuScope 14100C comes standard with external clocking capability that allows synchronization of the
digitizers with an external system.
•
Trigger Output
CompuScope 14100C provides a TTL output that signifies the occurrence of a trigger event on the card.
This signal can be used to synchronize other parts of the measurement signals to the CompuScope 14100C.

CompuScope 14100C: identifying your CompuScope card(s)
Your CompuScope 14100C card is composed of the CS14100C base board and the CS14100C analog board.
You will find your CompuScope 14100C card type and version as shown in Figure 69 and Figure 70. Figure 69
also shows the location of the Calibration label. The Calibration label lists your CompuScope card’s serial
numbers. You should record these serial numbers for future reference on the technical support form found at the
front of this guide.
You may also see an “OPTION/MOD” label listing any upgrades or modifications that have been performed on
your card. For example, if you have purchased a CompuScope 14100C-1M card, the “OPTION/MOD” label
will list “1M” as an option.

Figure 70: CS14100C hardware version number
If you have purchased a multi-card system, you will notice that input channel connectors on one card are
numbered “CH 1” & “CH 2” and the other “CH 3” & “CH 4” and so on.
The MASTER card is labeled “CH 1” & “CH 2” and each SLAVE card is labeled with successive channel
numbers.

If you purchased a CompuScope 14100C card with 8M, 128M or 1G on-board acquisition memory, you should
notice that the expanded memory card occupies a second slot. Such a 2-slot product is also referred to as a
“Deep Memory Card” or, in the case of the 128M and 1G versions, an “Extreme Memory Card”.
The exact amount of on-board acquisition memory is listed on the OPTION/MOD sticker.

CompuScope 14100C connectors and headers
CompuScope cards connect to the outside world through connectors, both analog (BNC) and digital
(CompactPCI Bus, Master/Slave, etc.). This section describes these connectors for the CS14100C card.
The connectors and headers on the CS14100C card are shown below:
Figure 73: Connectors on CS14100C
122
•
CH 1 BNC connector is the single-ended input of channel 1 that is used to input an analog signal that is
sampled as Channel 1.
•
CH 2 BNC connector is the single-ended input of channel 2 that is used to input an analog signal that is
sampled as Channel 2.
•
External Trigger BNC connector is used to input an analog or digital signal, which may be used as an
External Trigger. External Trigger is defined exactly as in an oscilloscope: this signal can be used to
trigger the system but cannot be viewed or digitized.
•
External Clock BNC connector is located on the front panel. This input can be used for injecting a
specific clock signal for digitizing the analog inputs. See the section CompuScope 14100C External
Clock for more details.
CompuScope 14100C
•
Master/Slave connector is located on the front panel. This connector is used to pass Clock, Trigger
and Initialization signals from a Master card to Slave card(s) using a Master/Slave Timing Module.
•
Trigger Out BNC connector is located on the front panel near the bottom of the card. This connector
outputs a TTL signal, the low to high transition of which signifies the occurrence of a trigger event on
the CS14100C. See the section CompuScope 14100C Trigger Output for more details.
•
CompactPCITM connector is located at the rear of the card. This is an industry standard connector
that complies with all specifications of the CompactPCITM bus.
•
Status LEDs are located at the bottom of the front panel. Note that the BUSY LED is illuminated
when the CompuScope 14100C is capturing a signal. The TRIG LED is illuminated after the
CompuScope 14100C receives a trigger.
CompuScope 14100C
123
CompuScope 14100C triggering
CompuScope 14100C features state-of-the-art Windowed triggering. The user has the ability to set up two
independent triggers that are ORed by the on-board circuitry.
Each of the two triggers are designed to be similar to an oscilloscope, so the user can easily replace the Digital
Oscilloscope in his or her application with a CompuScope 14100C. A user can select the trigger source, trigger
level and trigger slope using software commands.
The user can software-select the trigger source from any one of the following:
•
•
•
•
Channel 1
Channel 2
External Trigger
Software Trigger
The selected trigger source is then compared to a trigger level set by an on-board, 8 bit software-controlled
DAC. An on-board, high-speed comparator is used for this function, making it possible to trigger on narrow
pulses or glitches that are much shorter than the sample rate, subject to the 30 MHz bandwidth limitation of the
front-end trigger circuitry.
Each time the selected signal crosses the trigger level, the on-board triggering circuitry monitors it for the slope
selected by the user. When the appropriate slope is detected, a Trigger signal is generated.
Figure 74: Generation of a trigger signal (negative slope)
124
CompuScope 14100C
Windowed triggering
Using the CompuScope 14100C’s ability to have two independent trigger sources which are ORed together, the
user can set up the triggering such that a trigger will occur if the input signal is outside a specified “window,” i.e.
it is higher than the upper limit or lower than the lower limit.
Figure 75: Windowed triggering
External Trigger amplifier
The External Trigger input also has oscilloscope-like 1 MΩ / 35 pF input impedance.
Gage’s proprietary input-protection circuitry allows the FET stage to withstand voltages as high as ±15 Volts
without causing any damage to the inputs.
The trigger comparators have an operating range of ±1 Volt. Software-selectable attenuation of X1 or X5 on the
External Trigger input allows input ranges of ±1 Volt and ±5 Volt, respectively.
CompuScope 14100C
125
CompuScope 14100C External Clock
External clocking is a very powerful feature in a digitizer. It allows the user to synchronize the digitizer to an
external system.
On the CompuScope 14100C, external clock signal must be a continuous sine wave signal of amplitude between
1 V RMS and 2 V RMS. Note that the external clock input is AC coupled, so DC biases get canceled.
In single channel mode, the allowable external clock frequency is between 40 MHz and 100 MHz. Sampling is
done on each “rising edge” of the sine wave.
In dual channel mode, the allowable external clock frequency is between 20 MHz and 50 MHz. Sampling is
done on each “rising edge” of the sine wave.
Note that high-resolution waveform digitizers are very sensitive to phase noise and duty cycle of the external
clock input. All efforts should be made to minimize jitter and distortion on the external clock signal.
Care should be taken not to inject a TTL or CMOS signal (0 to 5 Volts) into the external clock input, as it may
result in saturation of the input circuitry.
126
CompuScope 14100C
CompuScope 14100C Trigger Output
A Trigger signal is used to synchronize different parts of a measurement system to the same event.
CompuScope 14100C provides a TTL output on one of the front panel connectors. The rising edge of this
output signifies that a trigger event has been detected on the CompuScope 14100C.
In a Master/Slave configuration, only the Trigger Output of the Master card should be used.
For best results, this output should be terminated with a 50 Ω load capable of absorbing 0.5 Watt power.
It should be noted that this output is synchronized to an internal clock, called GCLK, on the CompuScope
14100C. This clock is not the same as the sampling clock.
The relationship between GCLK and sampling clock must be understood in order to take full advantage of this
powerful feature.
Single channel mode
In single channel mode, GCLK is always one-half the frequency of the sampling clock. Consequently, if the
trigger event is asynchronous to the sampling clock, Trigger Out signal will only be activated after one of the two
subsequent rising edges of the sampling clock.
Figure 76: Trigger Out in single channel mode
Dual channel mode
In dual channel mode, GCLK is exactly the same frequency as the sampling clock. Consequently, if the trigger
event is asynchronous to the sampling clock, Trigger Out signal will only be activated after the subsequent rising
edge of the sampling clock.
Figure 77: Trigger Out in dual channel mode
Finally, note that there is no output short protection on this signal, so care should be taken in not interfacing it to
any output, be it Ground or any other voltage.
CompuScope 14100C

CompuScope 14100C throughput & maximum PRF
A number of applications require the CompuScope 14100C to acquire data based on a rapidly occurring trigger
signal. These high Pulse Repeat Frequency (PRF) applications include imaging, radar, ultrasound and lightning
test.
Gage has performed extensive repetitive capture benchmarks in single record mode. In this mode, the signal is
captured into on-board CompuScope memory and the captured data are transferred through the PCI bus using
PCI bus mastering to PC RAM.
Please note that much higher PRFs will be achieved using CompuScope Multiple Record mode.
The following test results were obtained using a computer configured as follows:
• Pentium III, 500 MHz processor
• 128 MB RAM
• 20 GB disk drive
• Windows NT 4.0 with SP6
• NT File System
• 33 MHz, 32 bit CompactPCITM bus
• All slots support bus mastering
A C application program optimized for fast repetitive capture in single record mode was used for throughput
measurements. The CS14100C was operated using this application in both single and dual channel mode for
many different capture depths and the results are plotted as points in the graph below. The PCI transfer rates
were calculated from the linear portion of the curves at high depths.

CompuScope 1610C
CompuScope 1610C product introduction
CompuScope 1610C is a 16 Bit, dual channel 10 MS/s data acquisition card for the CompactPCITM Bus, the
world’s fastest 16 bit waveform digitizer.
Recognizing that until very recently, almost all multi-MegaHertz data acquisition was done using Digital Storage
Oscilloscopes under GPIB control, Gage has ported all the features of these DSOs onto the CompuScope card.
This means that you do not have to rethink the solution in terms of a completely unknown data acquisition card.
You can simply develop the data acquisition system as if an oscilloscope were being used, but instead use a
CompuScope card to take advantage of its attractive price and performance.
Of course, CompuScope cards are much more than just another DSO under GPIB control:
•
CS1610C features 16 bit vertical resolution as opposed to the 8 bit resolution offered by DSOs.
•
Multi-card Master/Slave systems provide from 2 to 16 channels of simultaneous A/D conversion, something
normal DSOs simply cannot do.
•
Data transfer rates from CompuScope memory to PC memory or extended memory run as high as 50 MB/s
for the CS1610C as compared to a few hundred KB/s for GPIB.
•
CompuScope cards are easier to program, as Software Development Kits (SDKs) are available for C/C++,
MATLAB, LabVIEW and LabWindows/CVI.
•
CompuScope cards are installed inside the CompactPCITM chassis, so there is no external box such as a
DSO.
•
The CS1610C cards have standard features such as Multiple Record and External Clocking, which help
optimize the use of the on-board memory by stacking data from successive bursts.
•
You can also write software for a multi-card system in which all the cards are not in a Master/Slave
configuration. Drivers supplied by Gage support all these multi-card configurations.
Special features on the CompuScope 1610C include:
•
Bus Mastering
CompuScope 1610C is fully capable of becoming a bus master in order to transfer data at the maximum rate
of 50 MB/s.
A bus Master is a card that can take control of the bus and transfer data to any PCI target device such as
system RAM without any involvement from the CPU.
When a CompactPCITM card such as the CompuScope 1610C becomes the bus master, it is said to be
operating in the Master Mode.
On the other hand, when the CPU is controlling the transfer of data from the add-on card to its system RAM,
the card is said to be working in the Slave mode.
•
External Clocking
CompuScope 1610C comes standard with external clocking capability that allows synchronization of the
digitizers with an external system.
It should be noted that the frequency of the external clock must be twice the desired sampling frequency.

CompuScope 1610C: identifying your CompuScope card(s)
Your CompuScope 1610C card is composed of the CS1610C base board and the CS1610C analog board.
You will find your CompuScope 1610C card type and version as shown in Figure 80 and Figure 81. Figure 80
also shows the location of the Calibration label. The Calibration label lists your CompuScope card’s serial
numbers. You should record these serial numbers for future reference on the technical support form found at the
front of this guide.
You may also see an “OPTION/MOD” label listing any upgrades or modifications that have been performed on
your card. For example, if you have purchased a CompuScope 1610C-1M card, the “OPTION/MOD” label will
list “1M” as an option.

Figure 81: CS1610C hardware version number
If you have purchased a multi-card system, you will notice that input channel connectors on one card are
numbered “CH 1” & “CH 2” and the other “CH 3” & “CH 4”.
The MASTER card is labeled “CH 1” & “CH 2” and the SLAVE card is labeled “CH 3” & “CH 4”.

If you purchased a CompuScope 1610C card with 8M, 128M or 1G on-board acquisition memory, you should
notice that the expanded memory card occupies a second slot. Such a 2-slot product is also referred to as a
“Deep Memory Card” or, in the case of the 128M and 1G versions, an “Extreme Memory Card”.
The exact amount of on-board acquisition memory is listed on the OPTION/MOD sticker.

CompuScope 1610C connectors and headers
CompuScope cards connect to the outside world through connectors, both analog (BNC) and digital
(CompactPCI Bus, Master/Slave, etc.). This section describes these connectors for the CS1610C card.
The connectors and headers on the CS1610C card are shown below:
Figure 84: Connectors on CS1610C
144
•
CH 1+ BNC connector is the positive differential input of channel 1 which is used to input an analog
signal that is sampled as Channel 1.
•
CH 1- BNC connector is the negative differential input of channel 1 which is used to input an analog
signal that is sampled as Channel 1.
•
CH 2+ BNC connector is the positive differential input of channel 2 that is used to input an analog
signal that is sampled as Channel 2.
•
CH 2- BNC connector is the negative differential input of channel 2, which is used to input an analog
signal that is sampled as Channel 2.
CompuScope 1610C
•
External Trigger BNC connector is used to input an analog or digital signal, which may be used as an
External Trigger. External Trigger is defined exactly as in an oscilloscope: this signal can be used to
trigger the system but cannot be viewed or digitized.
•
External Clock BNC connector is located on the front panel. This input can be used for injecting a
specific clock signal for digitizing the analog inputs. See the section CompuScope 1610C External
Clock for more details.
•
Master/Slave connector is located on the front panel. This connector is used to pass Clock, Trigger
and Initialization signals from a Master card to Slave card(s) using a Master/Slave Timing Module.
•
Trigger Out BNC connector is located on the front panel near the bottom of the card. This connector
outputs a TTL signal, the low to high transition of which signifies the occurrence of a trigger event on
the CS1610C. This signal is synchronized to the sampling clock. See the section CompuScope 1610C
Trigger Output for more details.
•
CompactPCITM connector is located at the rear of the card. This is an industry standard connector
that complies with all specifications of the CompactPCITM bus.
•
Status LEDs are located at the bottom of the front panel. Note that the BUSY LED is illuminated
when the CompuScope 1610C is capturing a signal. The TRIG LED is illuminated after the
CompuScope 1610C receives a trigger.

CompuScope 1610C triggering
CompuScope 1610C features state-of-the-art Windowed triggering. The user has the ability to set up two
independent trigger sources per card that are ORed by the on-board circuitry.
Each of the two trigger sources are designed to be similar to an oscilloscope, so the user can easily replace the
Digital Oscilloscope in his or her application with a CompuScope 1610C. A user can select the trigger source,
trigger level and trigger slope using software commands.
The user can software-select the trigger source from any one of the following:
•
•
•
•
Channel 1
Channel 2
External Trigger
Software Trigger
The selected trigger source is then compared to a trigger level set by an on-board, 12 bit software-controlled
DAC (only the 8 most significant bits are actually used). An on-board, high-speed comparator is used for this
function, making it possible to trigger on narrow pulses or glitches that are much shorter than the sample rate.
Each time the selected signal crosses the trigger level, the on-board triggering circuitry monitors it for the slope
selected by the user. When the appropriate slope is detected, a Trigger signal is generated.
Figure 85: Generation of a trigger signal – negative slope
146
CompuScope 1610C
Windowed triggering
Using the CompuScope 1610C’s ability to have two independent trigger sources which are ORed together, the
user can set up the triggering such that a trigger will occur if the input signal is outside a specified “window,” i.e.
it is higher than the upper limit or lower than the lower limit.
Figure 86: Windowed triggering
Channel 1 or 2 triggering
There are occasions when it is not possible to predict if the trigger is going to occur on Channel 1 or 2. For
example, if the CompuScope 1610C is hooked up to two photon detectors that are picking up random or
intermittent pulses, the user is not able to select the trigger source.
The CompuScope 1610C can be put in a mode in which it will trigger on, say, the rising edge of a pulse on
Channel 1 or on the rising edge of a pulse on Channel 2.
In other words, by selecting two different sources with independent levels and slopes, the user can generate a
trigger on the first occurrence of the pulse on either of the two channels.
Trigger bus for Master/Slave systems
In a Master/Slave system, any one of the input channels can be used as a trigger source.
This is achieved by having a trigger bus in the Master/Slave Timing Module that causes any one of the
CompuScope 1610C cards in the system to cause the entire system to trigger.
This powerful feature allows the use of a multi-channel, Master/Slave CompuScope 1610C system for acquiring
signals in a system in which the user cannot predict which channel would receive the trigger signal. Examples of
these applications are explosion testing and acoustic emission testing.
External Trigger amplifier
The External Trigger input also has oscilloscope-like 1 MΩ / 30 pF input impedance.
Gage’s proprietary input-protection circuitry allows the FET stage to withstand voltages as high as ±15 Volts
without causing any damage to the inputs.
The trigger comparators have an operating range of ±1 Volt. Software-selectable attenuation of X1 or X5 on the
External Trigger input allows input ranges of ±1 Volt and ±5 Volt, respectively.
CompuScope 1610C
147
CompuScope 1610C External Clock
External clocking is a very powerful feature in a digitizer. It allows the user to synchronize the digitizer to an
external system.
It is important to note, however, that the external clock for CompuScope 1610C must be 2 times faster than the
required sample rate, i.e. if 8 MS/s sampling is required, the external clock must be 16 MHz.
A corollary to this is that the “sampling clock” will always be a divide-by-2 of the external clock.
The External Clock must be a TTL signal (0 to +5 Volts) with a maximum frequency of 20 MHz and minimum
frequency of 2 kHz.
The rise and fall times of the clock signal must be better than 8 ns for proper operation at the peak sample rates.
A minimum pulse width of 22.5 ns must be respected.
In other words, the duty cycle of the clock must be between 50% and 55%.
148
CompuScope 1610C
CompuScope 1610C Trigger Output
A Trigger signal is used to synchronize different parts of a measurement system to the same event.
CompuScope 1610C provides a TTL output on one of the front panel connectors. The rising edge of this output
signifies that a trigger event has been detected on the CompuScope 1610C.
For best results, this output should be terminated with a 50 Ω load capable of absorbing 0.5 Watt power.
It should be noted that this output is synchronized to the sampling clock of the CompuScope 1610C.
Consequently, if the trigger event is asynchronous to the sampling clock, Trigger Out signal will only be
activated after the subsequent rising edge of the sampling clock.
Figure 87: Trigger Out signal vs. sampling clock
If an External Clock is being used, Trigger Out signal will have a 2 external clock cycle uncertainty relative to
trigger input.
Finally, note that there is no output short protection on this signal, so care should be taken in not interfacing it to
any output, be it Ground or any other voltage.

CompuScope 1610C throughput & maximum PRF
A number of applications require the CompuScope 1610C to acquire data based on a rapidly occurring trigger
signal. These high Pulse Repeat Frequency (PRF) applications include imaging, radar, ultrasound and lightning
test.
Gage has performed extensive repetitive capture benchmarks in single record mode. In this mode, the signal is
captured into on-board CompuScope memory and the captured data are transferred through the PCI bus using
PCI bus mastering to PC RAM.
Please note that much higher PRFs will be achieved using CompuScope Multiple Record mode.
The following test results were obtained using a computer configured as follows:
• Pentium III, 850 MHz processor
• 256 MB RAM
• 20 GB disk drive
• Windows 98
• 33 MHz, 32 bit CompactPCITM bus
• All slots support bus mastering
A C application program optimized for fast repetitive capture in single record mode was used for throughput
measurements. The CS1610C was operated using this application for many different capture depths and the
results are plotted as points in the graph below. The PCI transfer rate was calculated from the linear portion of
the curve at high depths.

CompuScope 3200C
CompuScope 3200C product introduction
The CompuScope 3200C is a CompactPCI bus based board-level product which allows the user to capture up to
32 bits of single-ended CMOS/TTL or differential ECL/PECL digital data into on-board memory of up to 2
Gigabytes at clock rates up to 100 MHz.
The CS3200C can also be configured, in software, to be 8, 16 or 32 bits wide, thereby allowing the user to
maximize the use of acquisition memory for 8 or 16 bit inputs.
Multiple CompuScope 3200C cards can be used simultaneously to provide input of more than 32 bits. Consult
the factory for Master/Slave synchronous timing modules to provide for word widths of up to 256 bits.
INPUT CIRCUITRY
The input stage of the CS3200C consists of 34 high-speed comparators: 32 for data and one each for clock and
trigger. The use of high-speed comparators with fully programmable thresholds allows the use of virtually any
logic level: 5V TTL/CMOS, 3.3V CMOS, 2.7 V CMOS, ECL, PECL or even custom logic levels.
Inputs need to be driven by a source capable of driving a 50 Ω load. This is necessary in order to maintain good
signal integrity.
For CMOS or TTL signal sources not capable of driving 50 Ω loads, a special Buffer Board is available from
Gage, which buffers the data with 50 Ω drivers. The input of the Buffer Board is a 68 pin IDC header for data, a
BNC connector for Trigger and another BNC for Clock input. All input signals must be 0 to 3.3 V or 0 to 5V
CMOS or TTL signals.
The output of the Buffer Board is a 68 pin MDR connector which connects to the CS3200C using a 6 foot long
pleated foil cable, supplied with the CompuScope 3200C.
Differential ECL or PECL signals are, by definition, capable of driving a 50 Ω load and interface seamlessly
with the CompuScope 3200C.
CONFIGURABLE INPUT
The output of the on-board comparators is fed into an on-board FPGA, which maximizes the use of on-board
memory for data from 8, 16 or 32 bits of width.
The presence of this FPGA also makes it possible to build customized digital acquisition systems, including
front-end data processing, for specific requirements. Contact the factory for such custom applications.
Customers must decide at the time of placing an order whether they require a differential ECL/PECL input or
single-ended CMOS/TTL input CompuScope 3200C. This setting must be configured at the factory and cannot
be modified in the field.
ON-BOARD MEMORY
The CompuScope 3200C card stores digital data in on-board acquisition memory, which is addressable through
the CompactPCI bus under software control.
The on-board memory is configured as a circular buffer, so it is possible to store both pre- and post-trigger data.
In other words, it is possible to wait indefinitely for a trigger event and then capture digital data from both before
and after this event.
The number of data words that can be captured into on-board memory is a function of the size of the memory
and input width. For example, a 2 MB model provides 2 million words of storage when the input is 8 bits wide.
The same model provides 512 K samples of memory with 32 bit word width.
TRANSFERRING DATA TO PC MEMORY
The CompuScope 3200C is fully capable of acting as a bus master to DMA captured data into user buffers.
CompuScope 3200C
153
EXTERNAL CLOCK
The CompuScope 3200C allows the use of either internal or external clocks. External clock can be very useful
in systems which require synchronous data capture. These applications include A/D Testing,
Telecommunication, DSP Systems, Video, Ultrasonic Imaging, etc.
The external clock is carried on the 68 wire input connector. A high-speed comparator converts the input level
of the clock to CMOS/TTL levels used by the on-board data latching and de-multiplexing circuitry.
The maximum clock frequency of the input clock is 100 MHz. The driving circuitry on the user’s circuit must be
capable of driving a 50 Ω load.
CLOCK EDGE SELECTION
The user is allowed to select either the rising or falling edge of the input clock to latch the data.
This flexibility allows the user to apply the CompuScope 3200C in situations in which one of the clock edges
and input data do not satisfy the timing requirements. In such cases, using the opposite edge of the clock may
resolve the timing conflict.
CLOCK AND DATA TIMING
If the customer operates the CompuScope 3200C with an external clock, it should be kept in mind that the
maximum speed of the input clock is 100 MHz with a rise and fall time of 2.5 ns or less. The minimum clock
frequency is zero, i.e. the clocks can be started and stopped at will, once the acquisition has started.
The setup and hold times of the data with respect to the active edge of the clock must satisfy the minimum
requirements listed in the specifications.
CRYSTAL-BASED TIMEBASE
The CompuScope 3200C allows the use of both Internal or External clocking under software control.
When the internal clock is selected, the sampling clock is provided by a crystal-controlled oscillator, thereby
providing very good short and long term timing accuracy.
When an external clock is used, the timing accuracy depends entirely on the quality of the external clock
supplied by the user.
INPUT CONNECTOR
The data is input to the CompuScope 3200C over a 68 wire Pleated Foil cable. The input connector is a 68 pin
MDR socket (P/N 3M 10268-55H3VC). The mating connector is a 3M 10168-6000EC. The mating connector
hood is a 3M 10368-A230-00.
Each CompuScope 3200C card is supplied with a 6 foot Pleated Foil cable featuring the 3M 10168-6000EC
connector.
TRIGGER
An External Trigger input is provided on the CompuScope 3200C. The configuration of this input is set at the
factory as either differential ECL/PECL or single-ended CMOS/TTL.
It is possible to trigger either on the rising or falling edge of this trigger input.
TRIGGER OUTPUT
A Trigger Output signal (5 Volt TTL) is also provided by the CompuScope 3200C. This signal is synchronized
to the internal clock which runs the de-multiplexed memory counters. As such, there can be a latency of as much
as 8 clock cycles between a trigger input and a trigger output.
This Trigger Output can be used to synchronize an entire system to Gage’s internal clock.
BNC BREAKOUT BOARD
One of the popular accessories for the CompuScope 3200C is a BNC Breakout Board which connects to the card
using the pleated foil cable and allows the user to inject digital data, clock and trigger signals using BNC coaxial
connectors.

If you purchased a CompuScope 3200C card with 256M or 2G on-board acquisition memory, you should notice
that the expanded memory card occupies a second slot. Such a 2-slot product is also referred to as an “Extreme
Memory Card”.
The exact amount of on-board acquisition memory is listed on the OPTION/MOD sticker.

CompuScope 3200C connectors and headers
The CompuScope 3200C accepts digital data using a connector designed specially for ultra-fast digital signal
transmission.
A Trigger Out signal is also available on a BNC connector in order to synchronize the CS3200C to the rest of the
test system. The connectors and headers on the CS3200C card are shown below:

•
Digital input MDR: this connector is used to input up to 32 bits of single-ended or differential digital
data lines, one clock input and one trigger input, all with 50 Ω characteristic impedance.
This connector is designed to provide “equivalent to coax” performance by using copper conductors
encapsulated in a specially formulated Teflon to provide the appropriate dielectric constant. This
assembly is wrapped in a pleated copper foil, resulting in a 50 Ω transmission line impedance for each of
the 68 conductors in the cable.
For more information on the technology used in this connector, please visit www.mmm.com.
•
Trigger Out BNC: this connector is used to output a 0 to 5 Volt, TTL signal which signifies that a
trigger event has occurred on the CS3200C.
•
Clock Out BNC: In some select cases, a user may want to drive the rest of the test system with the
internal clock of the CS3200C. A 5 Volt CMOS clock signal capable of driving a 50 Ω load is available
on the card as a standard feature for this purpose.

CompuScope 3200C triggering
Triggering allows the CompuScope 3200C to capture digital data just before or after an external event or
software command. The CS3200C supports both pre- and post-trigger data capture.
The CompuScope 3200C allows the user to trigger the system on:
• External Trigger
• Software Trigger
The user can also specify whether to trigger on the rising or falling edge of the External Trigger signal.

CompuScope 3200C digital input
The CompuScope 3200C is available with two different input configurations:
•
Single-Ended, TTL/CMOS Inputs
•
Differential, ECL/PECL Inputs
Users must specify one or the other at the time of placing an order. The two configurations cannot be changed
via software commands and require considerable changes to the input circuitry. As such, this change cannot be
made in the field and must be done at the factory.

Input comparators
The input stage for all inputs of the CS3200C is an EMI filter followed by a 50 Ω terminating resistor network
wide bandwidth analog comparator.
For single-ended input models, one of the inputs to the comparator is the input signal and the other is a
programmable voltage level generated by an on-board DAC (Digital to Analog Converter). This enables the
input stage to handle different voltage level CMOS signals, e.g. 3.3 Volt, 5 Volt etc.
For differential input models, both inputs of the comparator are fed by the two differential signals corresponding
to a particular input. For example, D0+ and D0- are fed into the inputs of the same comparator.

Front-end FPGA
At the heart of the CS3200C is a high-speed FPGA: all data lines, trigger and clock signals received from the
outside world are injected into it; all data de-multiplexing is done inside it; all acquisition control state machines
exist in it; all sampling clock selection circuitry resides in it; all triggering is done within it.
This design allows for tremendous flexibility in adapting the CS3200C for a number of customized applications
that require not only fast digital data acquisition, but also some data manipulation. Contact the factory with your
custom requirement.
This FPGA also allows the CS3200C to work in one of three input word widths of 32, 16 or 8 bits by demultiplexing (DMUX) the data.
