: These functions are available according to the options installed in your X-Stream
oscilloscope. It can be very useful to run a function in query mode to determine whether it is available
in your oscilloscope, and to determine the current form of the command in your model. The
response to any query can be copied straight into a program and used as a command. Functions can
also be defined using the VBS command (see Chapter 6).
Underlined names in the left column of this table represent Boolean expressions, which take the
values ON and OFF.
