Numerical values are returned without their unit. The default unit for each
command is reported in the command reference description.
Example: SOURce:GPRF:GENerator:RFSettings:FREQuency? MAX
Response: 3300000000 for 3.3 GHz
Boolean values are returned as 0 (for OFF) and 1 (for ON). Possible exceptions to
this rule are reported in the command reference description.
Example: SOURce:GPRF:GENerator:STATe?
Response: 1
Text (character data) is returned in short form (see also next section).
Example: SOURce:GPRF:GENerator:BBMode?
Response: DTON (for DTONe, dual tone)
5.2.4.5 SCPI Parameters
Most commands require one or more parameters to specify their function. The
parameters must be separated from the header by a "white space". Permissible
parameters are numerical values, Boolean parameters, text, character strings and
block data. The parameter types and the permissible ranges of values are specified in
the command description.
Numeric Values
Numeric values can be entered in any form, i.e. with sign, decimal point and exponent.
Values exceeding the resolution of the instrument are rounded up or down. The
mantissa may comprise up to 255 characters, the values must be in the value range –
9.9E37 to 9.9E37. The exponent is introduced by an "E" or "e". Entry of the exponent
alone is not allowed. In the case of physical quantities, the unit can be entered.
Permissible unit prefixes are G (giga), MA (mega), MOHM and MHZ are also
permissible), K (kilo), M (milli), U (micro) and N (nano). If the unit is omitted, the default
unit is used.
Example:
SOURce:GPRF:GENerator:RFSettings:FREQuency 1.5GHz is equivalent to
SOURce:GPRF:GENerator:RFSettings:FREQuency 1.5E9
Special numeric values
The texts MINimum, MAXimum, DEFault, UP and DOWN are interpreted as special
numeric values. A query returns the associated numerical value.
Example: Setting command:
SOURce:GPRF:GENerator:RFSettings:FREQuency MINimum
The query SOURce:GPRF:GENerator:RFSettings:FREQuency? returns
10000000.
The following special values can be used on the R&S CMW 500:
MIN/MAX denote the minimum and maximum value of a range of numeric values.
DEF denotes the preset value. This value is set by the *RST command.
