SCPI Data Formats
All data programmed to or returned from the dc source is ASCII. The data may be numerical or character
string.
Numerical Data Formats
Symbol
<NR1>
Digits with an implied decimal point assumed at the right of the least-significant digit.
Examples: 273
<NR2>
Digits with an explicit decimal point. Example: .0273
<NR3>
Digits with an explicit decimal point and an exponent. Example: 2.73E+2
<Nrf>
Extended format that includes <NR1>, <NR2> and <NR3>. Examples: 273

Response Data Types
Character strings returned by query statements may take either of the following forms, depending on the
length of the returned string:
<CRD>
Character Response Data. Permits the return of character strings.
<AARD>
Arbitrary ASCII Response Data. Permits the return of undelimited 7-bit ASCII. This data
type has an implied message terminator.
<SRD>
String Response Data. Returns string parameters enclosed in double quotes.
