Examples:
"fgain" = 22
"P V"
= 256
"P-S"
=
0
corresponding
to 5 mU/div
corresponding
to power of 1
corresponding
to power of 0
The resulting vertical scale is thus 5 mV/div. Such
a scale might occur in raw data records, in
averaging, extrema or sums of raw data records.
"fgain" = 17
"P V"
= 512
"P-s"
=
0
corresponding to I00 ~U/div
corresponding to power of 2
corresponding to power of 0
The resulting vertical scale is thus i00 ~V2/div.
Such a scale would result from the multiplication
of two raw data records.
"fgain" = 26
"P V"
= 64
"P-s"
=
0
corresponding to i00 mU/div
corresponding to power of 1/4
corresponding to power of 0
The
resulting
vertical
scale
is
thus
I00 mV**(I/4)/div (i.e. one-tenth of the fourth
root of volts per division). Such a scale might
result
from the double
application
of the
square-root operation on a raw data record.
"fgain" = -2
"P V"
= 256
"P-s"
= 256
corresponding
to 50 pU/div
corresponding
to power of 1
corresponding
to power of 1
The resulting vertical scale is thus 50 pVsecldlv.
This scale might result from an integration over a
raw data record.
The following cases can also occur:
- Both powers may be zero, corresponding to a dimensionless record,
e.g. resulting from a division of raw data records.
Powers may be negative, e.g. due to a division of raw data records,
followed by another division. Differentiation also gives negative
powers of the time unit.
