SCALE
LOG LIN
scales the vertical graticule divisions in logarithmic units
when LOG is underlined. When the SCALE LOG LIN
function is the active function, the logarithmic units per
division can be changed. Values may range from 0.1 to
20
dB
per division. When LIN is underlined, the vertical
scale is in linear mode which has a range of 1
kW
to 1
pW.
The reference-level value is set to the top of the screen and
the bottom graticule becomes zero volts. (Each division of
the graticule is one-eighth of the reference level in volts.)
Pressing SCALE LOG LIN always sets the units specified for
the current amplitude scale. Pressing
(-1
or powering
on the analyzer sets the default units.
