BERTScope® Clock Recovery

BERTScope® Clock Recovery

The BERTScope Clock Recovery CR Series advanced architecture measures and displays the PLL frequency response from 100 kHz to 12 MHz; the highest loop bandwidth available for jitter testing on the market today. The first clock recovery instruments to allow full control of parameters including loop bandwidth, peaking/damping, and roll off.

Features

Benefits

Data Rate Range up to 28.6 Gb/s Continuous data rate coverage for next generation I/Os including PCIe 3.0, 10GBASE-KR, 16xFC, 25 & 28G CEI and 100GBASE-LR-4 & ER-4.
Independent control, measurement, and display of phase lock loop (PLL) BW, JTF (jitter transfer function) and peaking. Provides accurate "Golden PLL" response for transmitter jitter compliance testing and stressed receiver sensitivity test calibration. Provides full flexibility for device characterization.
Clock Recovery Input Equalization Enables clock recovery on high ISI signals without impacting the data stream under test. Recovered clock enables other analysis including "clean eye", application of FIR filtering to signal, and BER testing.
Edge Density Measurement Allows instant determination of the mark density of the signal under test.
Jitter Spectral Analysis and Frequency Gated Integrated Jitter Measurements Provides 200 Hz to 90 MHz display of jitter vs frequency with cursor based measurements of jitter peaks' amplitude and frequency. Frequency gated integrated jitter measurements PCIe 2.0 compliance testing.
Optional 24 MHz PLL BW Meets the JTF bandwidth requirements of USB 3.0, 6 G SATA, and PCIe-Gen 3.
Extensive set of subrate (recovered) clock outputs. Frequently needed for device reference clocks.
