Units of Measured Values
This parameter field is used to set the unit for the trace. The units available in the
parameter list depend in the type of measurement.
Alternatively, if the checkbox is selected, the unit used in the analyzer will be used.
An overview with all the units that occur for the audio analyzer and their conversion for-
mulas is located in
Chapter 4.17, "Units" , on page 183.
Details concerning the numeric value display can be specified here for all linear units.
For example, it is possible to select whether voltage is to be given in V, mV, µV, etc. If
"Auto" is set, these unit prefixes are automatically adapted to the measured value.
The used unit will appear on the y-axis of the graph (see example below). Sometimes it
is better to use a label defined by the user; this label can be entered in the parameter
field.
Y-axis scaling
If the button for automatic scaling is selected, the audio analyzer uses the minimum
and maximum values of the available measurement cycle to automatically determine a
suitable value range for the graph to be displayed. This scaling is determined once and
retained until the autoscale function is triggered again.
If manual scaling is required, the upper and lower end value of the y-axis must be
entered in the two fields.
If a linear unit has been selected for the y-axis, this axis can be displayed with linear or
logarithmic subdivisions.
Gridlines
The settings Main Grid and Sub Grid are used to subdivide the bar graph.
