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 man-
tissa may comprise up to 255 characters, the exponent must lie inside the value range
-32000 to 32000. 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.
Allowed unit prefixes are G (giga), MA (mega), MOHM and MHZ are also allowed), K
(kilo), M (milli), U (micro) and N (nano). If the unit is missing, the basic unit is used.
Example:
SENS:FREQ:STOP 1.5GHz
=
SENS:FREQ:STOP 1.5E9
Units
For physical quantities, the unit can be entered. Allowed unit prefixes are:
●
G (giga)
●
MA (mega), MOHM, MHZ
●
K (kilo)
●
M (milli)
●
U (micro)
●
N (nano)
If the unit is missing, the basic unit is used.
Example:
SENSe:FREQ:STOP 1.5GHz
=
SENSe:FREQ:STOP 1.5E9
Some settings allow relative values to be stated in percent. According to SCPI, this unit
is represented by the
PCT
string.
Example:
HCOP:PAGE:SCAL 90PCT
Special numeric values
The texts listed below are interpreted as special numeric values. In the case of a
query, the numeric value is provided.
●
MIN/MAX
MINimum and MAXimum denote the minimum and maximum value.
●
DEF
DEFault denotes a preset value which has been stored in the EPROM. This value
conforms to the default setting, as it is called by the *RST command.
●
UP/DOWN
UP, DOWN increases or reduces the numeric value by one step. The step width
can be specified via an allocated step command for each parameter which can be
set via UP, DOWN.
