Scaling function results must be in the range of
-1.0E+24 to -1.0E-24
,
0.0
, or
+1.0E-24 to 1.0E+24
. Results outside these limits will be replaced with
-9.9E+37
(negative infinity),
0
, or
+9.9E+37
(positive infinity).
Following a reset (
*RST
) or instrument preset (
SYSTem:PRESet
), the scaling
function is set to
NULL
.
Scale Reference Value
The
NULL
,
PCT
,
PPM
, and
PPB
scaling functions require a reference value. For
PCT
,
PPM
, and
PPB
the value cannot be ‘0’
.
The reference can be obtained automatically
or specified directly with the commands:
CALCulate[1]:SCALe:REFerence:AUTO {OFF|ON}
CALCulate[1]:SCALe:REFerence:AUTO? (query form)
CALCulate[1]:SCALe:REFerence {<reference>|MINimum|MAXimum|DEFault}
CALCulate[1]:SCALe:REFerence? [{MINimum|MAXimum|DEFault}] (query form)
ON
- automatically selects the first measurement as the reference for all
subsequent readings in the reading count (trigger count x sample count).
OFF
disables automatic selection and requires the reference to be specified directly.
Following a reset (
*RST
) or instrument preset (
SYSTem:PRESet
), automatic
reference selection is enabled (
ON
).
<reference>
- specifies the reference value directly. The reference is used for all
readings in the reading count.
