10.5 Vertical Scaling Units
With the introduction of waveform processing functions, such as
multiplication, division, square-root, integration and differentiation,
which alter the vertical scaling units, a more general system for the
vertical scales must be introduced. Three variables are now involved:
"fgain" (byte 0) = "fixed vertical gain"
differently, by dropping
(Compare with Section 7.7).
now interpreted slightly
the notion of volts
22 = 5 mU/div
23 = I0 mU/div
24 = 20 mU/div
25 = 50 mU/div
..... 31 = 5 U/div
Where U now stands for a general unit, which may be a
product of a power of volts and of a power of seconds.
"P V" (bytes 36 + 37) = 256*power of volts
"P-s" (bytes 38 + 39) = 256*power of seconds
Thus, U = Volts**(P_V/256) * Seconds**(P_s/256).
NOTE: Whenever the WP01 waveform processing option is installed, "P V"
and "P s" are always valid, even in raw data records (see the following
example). However, in software versions without waveform processing,
they cannot be relied upon. (Of course, in these cases the vertical
scales are always in volts).
