 Talking Formats

 

<NR1>

 

Digits with an implied decimal point assumed at the right of the least-significant
digit.  Examples: 273   0273

 

<NR2>

 

Digits with an explicit decimal point.  Example: 273.    .0273

 

<NR3>

 

Digits with an explicit decimal point and an exponent.  Example: 2.73E+2 273.0E-2

 

 

 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.

 

<Bool>

 

Boolean data. Either form   0 | 1 or  OFF | ON may be sent with commands. Queries
always return a 0 or 1.

 
 Suffixes and Multipliers
 
 

Some SCPI commands let you send engineering units as suffixes to extend numeric parameters. The following table lists the
allowable suffixes and multipliers.

 Character Data
 

For query statements, character strings may be returned in either of the forms shown in table 2-3, 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.

 

 

String Response Data. Returns string parameters enclosed in double quotes.
