SX-14 In Stock

The Spirent SX/14 is a Data Link Simulator specifically designed to replicate the error and delay characteristics found in long distance terrestrial and satellite data links. This cutting-edge simulator is instrumental in providing engineers with highly realistic simulations of actual network conditions, enabling them to conduct thorough stress tests on new equipment and network applications under controlled and repeatable circumstances. Leveraging dual-channel and full-duplex operation, the SX/14 facilitates bi-directional testing by offering busrst errors, random bit errors, and programmable delays. Moreover, this simulator permits the customization of delay and error settings for each direction of the full-duplex data stream.

The SX/14 is compatible with a wide range of applications, including testing the functionality, reliability, and performance of encrypters, bridges, multiplexers, network applications, and other communication hardware and software. In link simulation scenarios, this simulator directly connects between two equipment components, effectively replacing conventional data links like satellite connections, WANs, or telephone networks. Additionally, the SX/14 can be seamlessly integrated into an existing data link to introduce additional delays or errors, or to simulate the effects of incorporating an extra link into the system. Each channel of this simulator features a variable length first-in-first-out delay buffer, offering users the flexibility to define delay and data rate parameters.

The SX/14 channels encompass both a Random Error Generator and a Burst Error Generator. The Random Error Generator emulates background errors arising from Gaussian noise, actively operating during gaps between error bursts and injecting logical errors as required. Meanwhile, the Burst Error Generator component reproduces periodic or sporadic error bursts, such as those resulting from protection switching or natural phenomena like lightning strikes. The SX/14 is capable of introducing logical, forced-to-1, and forced-to-0 error types. The Burst Length parameter defines the duration of the error burst, which can possess a fixed or random length measured in bits or milliseconds, with the time interval between bursts also being customizable. In the case of random lengths, the burst length parameter serves as the mean for a Rayleigh random distribution.

The SX/14 offers the advantage of programmed test sequences, enabling users to define sequences encompassing specific delay and error parameters. These sequences effectively replicate real-world delay and error patterns that unfold over a designated period of time. Each sequence can comprise up to 99 programmed steps, with each step containing a comprehensive set of parameters including data rate, delay, random errors, and burst errors. Users have the flexibility to program sequences to run automatically until completion, repeat automatically after executing the final step, or run manually with each step triggered by the user. When employing remote control via a PC, programmed test sequences can be saved on disk for future use in subsequent tests. Additionally, the SX/14 supports multiple timing options, including receive clock, internal clock, and external clock, ensuring seamless integration into diverse testing environments.
