9.1.5 Parameters
Most commands require a parameter to be specified. The parameters must be
separated from the header by a "white space". Permissible parameters are
numerical values, Boolean parameters, text, character strings, block data and
expressions. The type of parameter required for each command and the
permissible range of values are specified in the command description (see
Section 9.4).
Numerical values
Numerical values can be entered in several forms, i.e. with sign, decimal point
and exponent. Values exceeding the resolution of the device are rounded.
The mantissa may comprise up to 41 characters, the exponent must lie inside
the value range -37 to 37. The exponent is introduced by an "E" or "e". Entry
of the exponent alone is not permissible. In the case of physical quantities, the
unit can be entered. Permissible units are as follows:
• for frequencies GHz, MHz or MAHz, kHz and Hz, default
unit is Hz
• for times s, ms, Zs, ns; default unit is s
• for levels dBZV; default unit is dBZV
• for percentage PCT, default unit PCT
If the unit is missing, the default unit is used. Note that mHz (milli Hz) as a unit
is not used to avoid confusion with MHz (mega Hz) since SCPI is case
insensitive.
Example:
SENSe:FREQuency:STARt 123 MHz = SENSe:FREQuency:STARt 123E6
Special numerical
The texts MIN, MAX, UP, DOWN, INF, NINF, and NAN are interpreted as
special numerical values. In the case of a query, the numerical value is
provided.
Example:
Command: SENSe:FREQuency:STARt MINimum
Query: SENSe: FREQuency:STARt? Response: 9000
MIN/MAX MINimum and MAXimum denote the minimum and maximum
value.
UP/DOWN UP, DOWN increases or decreases the numerical value by one
step. The step width can be specified for most parameters with a
separate command. Some parameters can only be changed in
fixed steps (e.g. SENSe:BWIDth UP).
