2 - Introduction to Programming
NOTE: All RS-232 response data sent by the dc source is terminated by the ASCII character pair
<carriage return><newline>. This differs from GPIB response data which is terminated by
the single character <newline> with EOI asserted.

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
<Nrf+>
Expanded decimal format that includes <NRf> and MIN
2.73E2
implicit in the range specification for the parameter.
<Bool>
Boolean Data. Example: 0 | 1 or ON | OFF

Response Data Types

Character strings returned by query statements may take either of the 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.
