BERT Pattern Generator

   The Pattern Generator creates clock and NRZ data patterns used as stimulus for developing and evaluating digital communications systems and components. The Pattern Generators offers flexibility to create data streams of varying PRBS or user-defined patterns, at data rates from 1.0 – 32.0 Gbits/sec, with selectable signal offset, amplitude, timing and preemphasis to help you create the test signals you need.

   The Pattern Generator creates data patterns used as stimulus for developing and evaluating digital communications systems and components. The Pattern Generators offers flexibility to create data streams of varying PRBS or user-defined patterns, with selectable data rate,, timing and pre-emphasis to help you create the test signals you need.

   The Pattern Generator is a compact instrument that uses a built-in synthesizer or accepts an external clock input that is used to generate two channels of NRZ data at rates from 1.0 up to 32.0 Gbps each (28 Gbps is standard). Variable output delay is available on each channel for precise phase alignment.  Each channel is DC-coupled and supports 4 Tap pre-emphasis with differential amplitude up to 2 Vpp. Channel pattern sequence output can be synchronized to combine properly to form a higher speed 2:1 multiplex. 

External triggers can be used to trigger your oscilloscope on clock- or pattern-based triggers. A built-in error injector with selectable error profiles enables creating single-shot and repeating error signatures.

   The built-in calibration input provides sub-rate error detection that allows you to examine eye-diagrams and BER Bathtub analysis for sub-rate return channels.  This is perfect for use with applications that utilize a sub-rate loopback for receiver testing, such as DDR5.

BitWise Laboratories Privacy Notice

Thank you for choosing to be part of our community at BitWise Laboratories, Inc. We are committed to protecting your information and your right to privacy. If you have any questions or concerns about this privacy notice, or our practices with regards to your personal information, please contact us at info@bitwiselabs.com.

When you visit our website http://www.bitwiselabs.com, and more generally, use any of our services, we appreciate that you are trusting us with your personal information. We take your privacy very seriously. In this privacy notice, we seek to explain to you what information we collect and how we use it. If there are any terms in this privacy notice that you do not agree with, please discontinue use of our services immediately.

This privacy notice applies to all information collected through our services, as well as any related services, sales, marketing or events.

What information do we collect?

We collect no personal information unless you contact us and provide us with information. If you provide us information, we may use it for business purposes as described below. We collect no personal information on our devices or on our website.

When do BitWise devices communicate any information with BitWise servers?

Each BitWise device is its own web server providing user interface and Help web site services directly to you on your local network. When you use BitWise devices, you are not connecting to a centralized BitWise server. There are two features that do cause individual BitWise devices to communicate with a centralized BitWise server: One is the internet website Lookup Local Device IP Address feature that is initiated when you press the physical button on the back of the device. This causes the devices to connect to a centralized BitWise server and send your local network numeric IP address and device serial number so we can display it on the internet website and create a link you can use to access the user interface. The second feature that requires connecting to a centralized BitWise server is updating software. This is only done if and when you select to update your device. This process communicates the version numbers for individual software components inside your device in order to update your device appropriately.

How do we use your information?

We may use your information to send you product, support, service, marketing, and new feature information and/or information about changes to our terms, conditions, and policies.

Will your information be shared with anyone?

We may share your information with our business partners who may send you product, support, service, marketing and new feature information.

Please contact us if you have any questions about this notice or our privacy policy. Thank you.
