The parameters required for each command and the allowed range of values are speci-
fied 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 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
