With the ASDA-J jitter solution, LeCroy's SDA family of serial data analyzers can evaluate total as well as random (RJ) and deterministic (DJ) jitter using both reference-clock-based and non-clock-based methods. High-accuracy measurements can be performed for both optical and electrical serial data signals. Moreover, it permits measurement correlation with time-interval analyzers and sampling oscilloscopes.
A single SDA can accurately perform the same measurements that previously required a real-time digital oscilloscope, a time-interval analyzer, a sampling oscilloscope, and a bit-error-rate (BER) tester. Key is the addition of an "edge-to-edge" jitter-measurement mode to the standard "edge-to-reference" mode.
A jitter wizard function guides users through the instrument's setup and automatically detects sampling and bit rates in addition to signal pattern length. An enhanced precision digital clock-recovery system lets the SDA define loop bandwidth and the phase-locked loop's shape factor for accurate modeling of any receiver.
With the SDAs' two additional clock-recovery modes for PCI Express and HDMI, users can perform compliance measurements to those standards. A filtered jitter mode supports ITU-T and Sonet measurements. This mode displays peak-to-peak and rms values, as well as the jitter waveform on the SDA's screen. The ASDA-J also maintains features from the first-version ASDA, such as an eye-mask violation locator, bit-error analysis, and advanced jitter measurement (including ISI plots and filtered jitter).
The ASDA-J costs $9050. Delivery is four to six weeks.
