2.6 SCPI Data Formats
All data programmed to or returned from the AC source is ASCII. The data may be numerical or
character string.
2.6.1 Numerical Data Formats
Symbol Data Form
Talking Formats
Digits with an implied decimal point assumed at the right of the least-
significant digit. Examples: 273
Digits with an explicit decimal point. Example: .0273
Digits with an explicit decimal point and an exponent. Example: 2.73E+2
Boolean Data. Example: 0 | 1or ON | OFF
Listening Formats
Extended format that includes , and . Examples:
273 273. 2.73E2
Expanded decimal format that includes and MIN MAX. Examples:
273 273. 2.73E2 MAX. MIN and MAX are the minimum and maximum
limit values that are implicit in the range specification for the parameter.
Boolean Data. Example: 0 | 1

2.6.2 Character Data
Character strings returned by query statements may take either of the following forms, depending
on the length of the returned string:
Character Response Data. Permits the return of character strings.
Arbitrary ASCII Response Data. Permits the return of undelimited 7-bit ASCII.
This data type has an implied message terminator.
