Inject Calibrated Jitter with Digital Accuracy for Tolerance Measurements
Option SP1 is software that precisely creates periodic jitter and/or random jitter. When used with the E4438C ESG vector signal generator, these two jitter subcomponents are available at clock rates from 250 Kb/s to 6 Gb/s. The software takes advantage of the E4438C ESG's advanced complex IQ modulation capability to provide calibrated additive jitter with digital repeatability. This advanced I/Q modulation technique has an 80 MHz instantaneous bandwidth across the entire frequency range of the signal generator.
Typical Applications
High-speed digital transmission systems and digital I/O buses are often required to receive or regenerate data using a clock signal that is recovered or extracted from the data waveform. Variation in the data rate commonly known as jitter can complicate the clock recovery and data regeneration process. To guarantee a high level of performance in the presence of jitter, components and systems are typically required to adhere to a rigorous set of jitter performance standards. For design and test engineers working on new and emerging standards such as CEI, XFP, XFI, UXPi, Fiber Channel, Gigabit Ethernet, PCI Express and Serial ATA, the E4438C with Signal Studio for jitter injection software has proven to be the most repeatable and accurate jitter source.
This option can be added as a product upgrade.
