codes 13 (carriage return) and 10 (line feed) is sent via HP-IB, then the end-or-identify

A
predellned
function is an
analyzer
command
that returns a number that can be
operated on by other spectrum analyzer commands. Insert a
predefined function
into
a command statement where predefined function appears in the command syntax
chart.
If a predefined function takes a parameter (for example, PKPOS TRA), it can be used
only as the last parameter of an spectrum analyzer command that has two or more
predelined
functions as parameters. For example, MPY
VAR,PKPOS
TRB,HAVE CARD;
is illegal, but MPY
V-AR,DONE,HAVE
CARD; is not.
