CompuScope Certificate of NIST Traceable Calibration
Each CompuScope card is shipped with a Certificate of NIST Traceable
Calibration. NIST is the National Institute to Standards and Technologies
- the US organization that is responsible for the definitions and
measurement of metrology standards.
Prior to shipment, Gage runs each CompuScope card through a battery of
over 1000 automated performance verification tests using a NIST
traceable calibration source. The tested CompuScope is then considered a
NIST traceable calibration instrument for a period of one year – the
calibration interval that is generally accepted by the Test and
Measurement industry.

8CompuScope 1220
CompuScope 1220 product introduction
CompuScope 1220 is 12 bit dual channel, 20 MS/s waveform digitizer card for the PCI Bus.
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:
• CS1220 features up to 1 billion samples of on-board acquisition memory.
• 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 run as high as 50 MB/s for the CS1220 as
compared to a few hundred KB/s for GPIB.
• CompuScope cards are easier to program, as Software Development Kits are available for C/C++,
MATLAB and LabVIEW.
• CompuScope cards are installed inside the PCI bus chassis, so there is no external box such as a DSO.
• CS1220 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 of the CompuScope 1220 include:
• Bus Mastering
CompuScope 1220 cards are 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.
• External Clock
CompuScope 1220 comes standard with External Clocking capability that allows synchronization of the
digitizers with an external system.

CompuScope 1220 connectors and headers
CompuScope cards connect to the outside world through connectors, both analog (BNC) and digital (PCI Bus,
Master/Slave, etc.). This section describes these connectors for the CS1220 card.
The connectors and headers on the CS1220 card are shown below:
Figure 2: Connectors on CS1220
• Channel A BNC Connector for the single-ended input of channel A; used to input an analog signal that
is sampled as Channel A.
• Channel B BNC Connector for the single-ended input of channel B; used to input an analog signal that
is sampled as Channel B.
• External Clock connector BNC Connector used to supply an signal that will be used as the sampling
clock instead of the CompuScope card’s own oscillator.
• External Trigger BNC Connector 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.
• Master/Slave connector The Master/Slave connector is located near the top edge of the CompuScope
1220 card. In case of an Independent card (i.e. a card not upgraded to either a Master or a Slave), this
connector may not be present.
The Master/Slave Timing Module is used to pass all the signals necessary to synchronize Slave
CompuScope 1220 cards with the Master.
NOTE FOR COMPUSCOPE 1220 DEEP MEMORY BOARD USERS:
IF Y-CABLES ARE NOT CONNECTED BETWEEN THE POWER CONNECTORS OF YOUR
COMPUSCOPE DEEP MEMORY CARD(S) AND THE POWER SUPPLY OF THE CHASSIS, THE DEEP
MEMORY CARD(S) WILL NOT FUNCTION PROPERLY.

CompuScope 1220 throughput & maximum PRF
A number of applications require the CompuScope 1220 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, 1 GHz processor
• 512 MB RAM
• 20 GB disk drive
• Windows 2000
• NT File System
• 33 MHz, 32 bit PCI 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 CS1220 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.
PCI data transfer rate: 50 MB/s
