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 Response

Formats

<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

Parameter

Formats

<Nrf>

Extended format that includes

<NR1>, <NR2> and <NR3>.

Examples:

273 273. 2.73E2

<Nrf+>

Expanded decimal format that includes

<NRf>

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.

<Bool>

Boolean Data. Example:

0 | 1

ON | OFF

Suffixes and Multipliers

Class Suffix Unit

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.
