7.3 Introduction to Programming

All commands and response messages are transferred in form of ASCII codes. The
response messages must be read completely before a new command is sent, otherwise the
remaining response messages will be lost, and a query interrupt error will occur.

7.3.1 Conventions

Angle brackets <
Vertical bar
Square brackets [
Braces {

7.3.2 Numerical Data Formats

All data programmed to or returned from the AC source are ASCII. The data can be
numerical or character string.
Symbol
NR1 It is a digit with no decimal point. The decimal is assumed
to be at the right of the least significant digit.
NR2 It is a digit with a decimal point.
NR3 It is a digit with a decimal point and an exponent.

7.3.3 Boolean Data Format

The Boolean parameter <Boolean> takes only the form ON|OFF.

7.3.4 Character Data Format

The character strings returned by query command may take either of the following forms:
<CRD> Character Response Data: character string with maximum length of 12.
<SRD> String Response Data: character string.
> Items in angle brackets are parameter abbreviations.
| Vertical bar separates alternative parameters.
] Items in square brackets are optional. For example, OUTP [ :
STATe] means that : STATe may be omitted.
} Braces indicate the parameters that may be repeated. The
notation <A> {<, B>} means that parameter "A" must be
entered while parameter "B" may be omitted or entered once or
more times.
