turn to the previous menu automatically and the selected reference channel will be displayed in the “Source module:” line.

Choose signal

Select the “Signals” submenu by select- ing the “Choose signal…” line and press- ing the key.

Note: the parameters “Operation status” and “Validity” are not functional on the TO2. The list of signals will depend on the module chosen.

Select analog output number

Choose the desired analog output (1-8) to set the parameters. The number of out- puts depends on the analyzer configura- tion as 2, 4, 6, or 8.
