NEW Si 8500C for USB 3.0 Compliance Testing

USB 3.0

Also known as the SuperSpeed bus, USB 3.0 increases the maximum transfer rate to 5.0 Gbit/s.

It requires receiver testing to ensure interoperability at a BER of 10^-12 or better through Jitter Tolerance testing.  The BERTScope Family of products has you covered, with a simple setup and tools that go beyond simple pass/fail compliance so you can get troubleshooting done quickly.

What's New for USB Testing?

Symbol Filtering
In 8b/10b systems like USB 3.0, clock compensation symbols are often used to adjust for slightly different received and transmitted data rates.  This can cause problems when testing in loopback mode, as a non-deterministic number of clock compensation symbols may be present in the data stream, making it difficult for the detector to synchronize with a given test pattern. With the Symbol Filtering Software Option, the BERTScope can perform this “asynchronous” BER and Jitter Tolerance testing, making USB 3.0 receiver compliance testing simple and straightforward.  Read more…

CR Extended Loop Bandwidth
The Extended Loop Bandwidth Option on the BERTScope CR enables the correct 4.9 MHz USB 3.0 jitter transfer function bandwidth for transmitter testing.  Read more…

Why Choose BERTScope for USB 3.0 Testing?

• Jitter Tolerance testing to the USB 3.0 template for pass/fail results, or explore the boundaries of Device or Host performance using the Jitter Tolerance "Search" mode
• The BERTScope can generate jitter (i.e., 2UI = 400 ps of SJ at 500 kHz and 0.17UI of RJ) and Spread Spectrum Clock (SSC) simultaneously
• Generates true random Jitter (RJ) to and beyond 1E-12 margin
• Supports synchronous and asynchronous BER testing
• Ability to synchronize the test equipment to the test device clock using the BERTScope CR for true measurements of receiver amplitude and jitter margin with SSC
• Filtering of clock compensation symbols, such as SKP ordered sets for asynchronous BER measurements and Jitter Tolerance testing
• Programmable pre-emphasis with the BERTScope DPP for compliance to USB 3.0 and other serial bus standards
• Host and Device loopback initiation

• Jitter, eye opening specified at 10^-12 BER, easily measured with BERTScope
• Built-in SuperSpeed USB Equalization function is easily applied using BERTScope PatternVu option to view eye performance after equalizer and compliance channel
• Automated measurements, such as the SSC waveform modulation rate, SSC deviation, and transmitter de-emphasis ratio, go beyond compliance
