AWG710&AWG710B Arbitrary Waveform Generator User Manual

This section describes the Waveform Programming Language (WPL) syntax, rules, 
and command descriptions. There are also a number of programming examples at 
the end of this section.

This manual uses the Backus–Naur Form (BNF) notation, shown in Table 3-46, to 
describe commands.

Following are the general syntax rules for writing an equation file:

„

All spaces, line feeds, and tab codes are ignored unless in a string.

„

The concept of a line does not exist.

„

All data from a single quote (’) to the end of a line is regarded as a comment.

„

Alphabetical characters are case–insensitive unless in a string.

„

The concept of cursor does not exist. You always work with the whole 
waveform.

„

File attribute functions are unavailable in a waveform expression.

„

The maximum length of a string is 256 characters, including spaces. Even if 
two or more strings are linked by colons (:) in a string expression, the whole 
length of the linked strings must not exceed 256 characters or an error will 
occur.

„

The total length of strings in the whole equation program can be up to 1,000. 
(The length is the sum of the number of characters of the string(s) plus a 
character used as the internal terminal code.)
