Some codes require appendages (ON, OFF , 1, 2, etc .). Codes that do not have a front-panel
equivalent are HP-IB only commands . They use a similar convention based on the common
name of the function.
V alid Characters
The analyzer accepts the following ASCII characters:
letters
numbers
decimal points
+/0
semicolons (;)
quotation marks (")
carriage returns (CR)
linefeeds (LF)
Both upper- and lower-case letters are acceptable . Carriage returns , leading zeros , spaces , and
unnecessary terminators are ignored, except for those within a command or appendage . If the
analyzer does not recognize a character as appropriate , it generates a syntax error message and
recovers at the next terminator .
