4.4.5 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 the respective
command and the permissible range of values are specified in the command description (see
"Description of commands" on page 13).
Numerical values
Numerical values can be entered in any form, i.e. with sign, decimal point and
exponent. Values exceeding the resolution of the device are rounded up or
down. The mantissa may comprise up to 41 characters, the exponent must lie
inside the value range -999 to 999. 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,
µ
s, ns; default unit is s
for levels
dBuV; default unit is dBuV
for percentage
PCT, default unit PCT
If the unit is missing, the default unit is used.
Example:
SENSe:FREQuency 123 MHz = SENSe:FREQuency 123E6
Special numerical
The texts MINimum, MAXimum, UP, DOWN and INFinity are interpreted as
special numerical values.
In the case of a query, the numerical value is provided.
Example: Setting command:
SENSe:GCONtrol MAXimum
Query:
SENSe:GCONtrol
Response:
100
MIN/MAX
MINimum and MAXimum denote the minimum and maximum value.
UP/DOWN
UP, DOWN increases or reduces the numerical value by one step. The step
width can be specified for some parameter which can be set via UP, DOWN
via an allocated step command (see Annex C). Some parameters can only be
changed in fixed steps ( eg
SENSe
:
BWIDth UP
).
