5.7 Character Data Formats
For command statements, the <NRf+> data format permits entry of required characters.
For query statements, character strings may be returned in either of the forms shown in
the following table. It depends on the length of the returned string.
Symbol
Character Form
crd
Character Response Data. They permit the return up to 12 characters.
aard
Arbitrary ASCII Response Data. They permit the return of undelimited
7-bit ASCII. This data type is an implied message terminator (refer to
“Separators and Terminators”).
5.8 Separators and Terminators
In addition to keywords and parameters, GPIB program statements require the following
Data Separators:
Data must be separated from the previous command keyword by a space. This
is shown in examples as a space (CURR 3) and on diagrams by the letters
SP
inside a circle.
Keyword Separators:
Keywords (or headers) are separated by a colon (:), a semicolon(;), or both.
For example:
LOAD:SHOR ON
MEAS:CURR?;VOLT?
CURR:STAT:L1 3;:VOLT:L1 5
Program Line Separators:
A terminator informs GPIB that it has reached the end of a statement. Normally, this is
sent automatically by your GPIB programming statements.
The termination also occurs with other terminator codes, such as EOI. In this manual,
the terminator is assumed at the end of each example line of code. If it needs to be
indicated, it is shown by the symbol <nl>, which stands for “new line” and represents the
ASCII coded byte 0A hexadecimal (or 10 decimal).
