Scale and Units

Adjust the Y-axis scale to see the relevant portions of the data trace.
The Y-axis is divided into 10 graticules. A acquisition is shown on the screen as
a solid horizontal bar that can be placed at any graticule.
When RF Attenuation set to Auto, the RF Attenuation is coupled to acquisition.
How to set Scale

Scale Type [current setting]
—Log Logarithmic scale (default setting). The Y-axis reference line
represents the specified absolute acquisition in the current Unit
selection. Y-axis graticules show dB below or above the reference
line.
—Lin Linear scale. The Y-axis reference line represents the specified
absolute acquisition in the current Unit selection. Y-axis graticules
show percent of acquisition (%) below or above the reference line.
Autoscale
fit the Minimum and Maximum amplitude of the trace on the screen.
Scale Manually adjust the scale per division to view specific areas of the
current trace. Enter a value using the numeric keypad, the
the rotary knob. Then press Enter.
Ref Level Manually set the value of the reference line. Enter a negative
value by pressing Run/Hold (+/-) either before or after typing a value. This
can also change the RF Attenuation setting. See
page 152.
Ref Pos Manually set the position of the reference line. Values must be
between 0 (TOP line) and 10 (BOTTOM line). Default position is zero (top).
