The BERTScope automated test software allows customers to verify PHY and TSG compliance to the Serial ATA Listing requirements within 20 minutes for a dual rate 1.5 and 3.0 Gb/s product.
Receiver tolerance compliance, 60 minutes for the full RSG test, is complemented by a faster alternative, 2 minutes, search for margin test that shows how much additional jitter the DUT can tolerate.
The test suite is remarkable in accurate capture of SSC waveforms and jitter on these, as well as high resolution skew measurements, utilizing the 20 GHz bandwidth of the BERTScope B.
A similar compliance test suite software package is also available for PCI-Express 1.0a and 1.1 tests including optional receiver tolerance tests with de-emphasized BERTScope signals.
SyntheSys Research introduces the new BERTScope CRJ clock recovery instrument with jitter analysis capability at DesignCon 2007.
When used with a BERTScope signal integrity analyzer, the CRJ directly measures jitter components from the serial input data while simultaneously generating a recovered clock. The measurements include a spectral analysis of jitter components, along with a direct measure of duty cycle dependent jitter. In addition, the instrument retrieves the spread spectrum modulation waveform and frequency deviation from any SSC clocked data stream.
The jitter spectrum view allows users to validate their device compliance to serial data standards, such as PCI-E Gen 2 which specify a total jitter value over a band limited range of frequency.
A new SSC source option for the BERTScope generates adjustable SSC modulation from 0 to 10,000 ppm at programmable repetition frequencies from 28 kHz to 35 kHz with selectable down, up or center-spread modes covering FB-DIMM, PCI-Express, SAS and Serial ATA test applications.
In addition, the new BERTScope CRJ companion instrument retrieves the spread spectrum modulation from any SSC clocked data stream with a data rate of up to 12.5 Gb/s. The SSC waveform, modulation frequency, maximum and minimum frequency deviations are measured using a precision gated frequency counter technology. The waveform view allows users to instantly see any anomalies in the SSC modulation, which could result in errors in their receivers.
