Test Data Acquisition

LXI –LAN extension:

One of the most commonly used protocols is the LXI –LAN extension for instrumentation. The protocol has been developed by the LXI consortium and plays a major role in promoting the standard as well as ensuring interpretability. The major role of this protocol is in defining the communication standard as well as the exchange of data as well as its acquisition for those systems which use Ethernet as the communication standard. One feature of this standard is that it defines the data traveling through Ethernet. This is then applied to measurement and testing procedures through the test equipment. The test equipment whose test data acquisition can be obtained through this standard offers great advantages.

RS 232:

Another commonly used standard is the Recommended Standard 232, commonly referred to as RS 232. One of the most important applications of this standard is that it defines various electrical standards such as the signal rates, the voltage levels, etc. The mechanical characteristics of the interface, pin definitions as well as specifications are also defined by this important standard. The test data acquisition through the RS 232 standard takes place in the form of time series of data bits. This standard extends support to both asynchronous as well as synchronous transfer of data through the entire circuitry of the test equipment. The standard  is also of great use in the definition of the various voltage levels of the transmission as well as control lines, corresponding to both logic zero and logic one. These voltage levels may differ from circuit to circuit depending upon the input voltages put into the test equipment.
