NOTES
In all of the commands listed here, i, j and k
are integer values and f, t and v may be
integer, floating point or exponential notation.
Optional parameters are enclosed in curly
brackets. If optional parameters are omitted
then the current value of those parameters will
be sent back to the GPIB controller. For
example, the command "TM 3" sets the
Trigger Mode to mode 3 while the command
"TM" will return the response "3".
Also, blanks are ignored, case is ignored,
multiple commands may be sent on one line if
separated by semicolons. All responses are
terminated by a carriage return and a line feed.
The line feed is sent with an EOI.
The Delay and Output commands use integer
codes which are assigned to each front panel
BNC. The table for these assignment is given
below.
