The perfect combination of sophisticated hardware and software analysis

An essential tool

for analysis and optimizing of all RS232 and RS422/485 field-bus connections. It gathers exact information about every line change with up to 10 nanosecond precision – indispensable for each analysis of time depending protocols like Modbus RTU, Profibus or similiar.

OSI layer support

  • Concurrent analysis from the phys­ical tri-state signal to the top-most levels.
  • All layers are only a click away. Check the data signal behind a telegram or measure the time between bits, bytes or sequences.
  • Synchronize the display of differ­ent layers. Let the tri-state view follow the data or telegrams and vice versa.

More than one protocol ›

Using a powerful protocol template script engine the analyzer is able to parse all thinkable fieldbus protocols. And together with an unique box model it allows the user to format and summarize the telegram output in an extremely wide range. Read more...
