Adtech SX/12 Data Link Simulator
Part Number 120100 SX/12-0 Data Channel Simulator Mainframe
Part Number 120101 SX/12-1 Data Channel Simulator Mainframe
Part Number 120102 SX/12-2 Data Channel Simulator Mainframe
Overview
Adtech SX Series Data Link Simulators create the same delay and error characteristics caused by long distance terrestrial and satellite
data links. By providing realistic simulations of actual network conditions, they allow users to stress test equipment and network
applications without the expense and inconsistency inherent with on-line testing.
Utilizing dual-channel, full-duplex interfaces, these devices provide true bi-directional testing using programmable delays, random bit
errors, and burst errors. Multiple delay and error events can be programmed into complex sequences to simulate a wide variety of
adverse link conditions or even specific events such as targeting line framing bits and testing CPE alarm thresholds.
Adtech’s lowest priced simulator model, the SX/12, is available in three versions supporting link speeds up to 8.448 Mbps.
Applications
Adtech Data Link Simulators can be used to test the effects of digital data links on the operation, performance, and reliability of
multiplexers, bridges, encrypters, network applications, and related communications hardware and software products.
Example 1: Simulating a Data Link
When used for link simulation, these simulators connect directly
between two pieces of equipment to simulate conventional data
links such as satellite connections, terrestrial or data networks.
Example 2: Simulating an Additional Data Link
The simulators can also be used in line with a real data link to add
additional delays or errors. This simulates the effects of adding
one more link to the system.
