Commands Quick Reference
For example, <A> ::= <B> indicates that <A> can be replaced by <B> in any
statement containing <A>.
< > (Angle Brackets)
< > Angle brackets enclose words or characters that symbolize a program
code parameter or an interface command.
... (Ellipsis)
... An ellipsis (trailing dots) indicates that the preceding element may be
repeated one or more times.
n,..,p (Value Ranges)
n,..,p ::= all integers between n and p inclusive.
d (Digits)
d ::= A single ASCII numeric character 0 - 9.
Quoted ASCII String
A quoted ASCII string is a string delimited by either double quotes (") or
single quotes ('). Some command parameters require a quoted ASCII
string. For example, when using the Agilent VISA COM library in Visual
Basic, the command:
myScope.WriteString ":CHANNEL1:LABEL 'One'"
has a quoted ASCII string of:
'One'
In order to read quoted ASCII strings from query return values, some
programming languages require special handling or syntax.
Definite-Length Block Response Data
Definite- length block response data allows any type of device- dependent
data to be transmitted over the system interface as a series of 8- bit binary
data bytes. This is particularly useful for sending large quantities of data
or 8- bit extended ASCII codes. This syntax is a pound sign (#) followed by
a non- zero digit representing the number of digits in the decimal integer.
After the non- zero digit is the decimal integer that states the number of
8- bit data bytes being sent. This is followed by the actual data.
For example, for transmitting 1000 bytes of data, the syntax would be
