The Tektronix CR175A 17.5 Gb/s BERTScope Clock Recovery Instrument's 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. 150 Mb/s to 17.5 Gb/s with Continuous Data Rate Coverage to include Next-generation I/Os including PCIe 3.0, 10GBASE-KR, 16xFC, 25/28 G CEI, and 100GBASE-LR-4/100GBASE-ER-4. Accurate, Variable Loop Bandwidth from 100 kHz to 12 MHz, with Optional 24 MHz for the Jitter Transfer Function (JTF) Bandwidths of USB 3.0, SATA 6G, and PCIe Gen3. Accurate, Adjustable, Self-measured, and Displayed PLL Loop Bandwidth, Peaking, and JTF – Get the "Golden PLL" Response Needed for Standards Compliance Testing. Programmable Peaking Adjustment with First- and Second-order Rolloff Capability. USB Control Interface Integrated into BERTScope View, or Stand-alone with included BERTScope PC Software. DC-coupled Data Through Path for Accurate Signal Integrity. Full and Divided Clock Outputs with Selectable Divide Ratios. Full-rate Clock Output up to 14.3 Gb/s, Half-rate Clock Output from 14.3 Gb/s to 17.5Gb/s. Built-in Equalizer Function enables Clock Recovery under High ISI Input Conditions. Edge Density Measurement – Determine the mark density of the signal under test. Spread Spectrum Clock Waveform View including dF/dt. Ideal for Spread Spectrum Clock (SSC) Applications with Large Frequency Excursions. Optional Direct Spectral Analysis of Jitter Components when under USB Control from BERTScope or on PC using Provided “stand-alone” SW. Optional “Spectrum Analyzer” Display with Cursor Measurements of Jitter Amplitude and Frequency. Optional PCIe 2.5, 5, and 8 Gb/s PLL Loop Analysis (Also requires jitter analysis option). Tektronix CR286A offers Optional Higher-sensitivity Data Inputs with Clock Recovery on Signals as Small as 40 mV Amplitude (Single ended), 20 mV Amplitude (Differential) – No DC-coupled Data Through Path with this Option. Options. PCIE, PCIe PLL analysis (requires 12GJ, operates at 2.5 G and 5 G only). PCIE8G, PCIe PLL analysis (requires 12GJ, operates at 2.5 G, 5 G and 8 G ). HS, Add High-sensitivity Clock Recovery (This option has no data outputs). XLBW, Add Extended Loop Bandwidth in the clock recovery. 17GJ, Add Jitter Spectrum Analysis from 1.2 to 11.2 Gb/s.
