| Listening Formats |
<NRf> | Extended format that includes <NR1>, <NR2> and <NR3>. Examples: 273 273. |
| 2.73E2 |
<NRf+> | Expanded decimal format that includes <NRf>, MIN and 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
Either form {10} or {ONOFF} may be sent with commands. Queries always return 1 or 0.
OUTPut OFF
CURRent:PROTection 1
Character Data
For query statements, character strings may be returned in either of the forms shown in Table
| Table |
<CRD> | Character Response Data. Permits the return of character strings. |
<AARD> | Arbitrary ASCII Response Data. Permits the return of undelimited |
| an implied message terminator. |
Note: | The IEEE 488.2 format for a string parameter requires that the string be enclosed within either single |
| (' ') or double (" ") quotes. Be certain that your program statements comply with this requirement. |

Examples
The examples given here are generic, without regard to the programming language or type of GPIB interface. Because SCPI commands are sent as ASCII output strings within the programming language statements, the SCPI syntax is independent of both programming language and interface.
Note | The examples are followed by sample program code written for three popular types of BASIC- |
| controlled GPIB interfaces. |
