The BERTScope CRJ Variable Clock Recovery Jitter Analyzer is based on our BERTScope CR, the highest performance instrumentation-grade adjustable clock recovery product available today. The CRJ retains all of the functionality of the current BERTScope CR, with additional Jitter Analysis capabilities. The jitter spectrum display lets you quickly validate device compliance to serial data standards, such as PCIe 2.0, which specify a total jitter value over a band-limited range of frequency. These measurements are also very useful in isolating the source of excessive jitter in a system. The BERTScope CRJ also directly measures Duty Cycle Dependent Jitter (DCD). The result appears in the BERTScope CRJ Display with a table of values and a graphical Level Histogram.
