Q-Value
This field contains a nonzero Q-Value, which are fractional representations of
integer values.The data on the actual/simulated target is interpreted using the
Q-Value. They are formed by inserting a decimal space in the binary
representation of an integer, resulting in greater precision. The Q-Value
indicates amount of the displacement, according to the formula:
New_integer_value = 2Q-Value
A Q-Value of xx indicates a signed 2s complement integer whose decimal
point is displaced xx places from the least significant bit (LSB).

Sampling Rate
This field contains the sampling frequency for acquisition buffer samples,
such as for analog to digital conversion. The values for the axis are from 0 to
(Display Length * 1/Sampling Rate). The Pre-Trigger (in samples) parameter
is subtracted from these values to give the labeled axis values.
6.3.15
Trigger Level
This field sets the 0-crossing level if the Trigger Source field is enabled.
6.3.16
Maximum Y-Value
This value sets the maximum value of the Y-axis displayed on the graph. The
values in the Maximum Y-Value and the Trigger Level fields determine the
minimum value of the Y axis.
6.3.17
Axes Display
This option turns the X and Y axes in the graph window on and off. Selecting
On enables the axes and Off disables them.
