The bit correlation and bit length analysis tools allow the measurement of bit length. Bit length analysis relies on a statistical evaluation of many individual measurements, whereas the bit correlation function displays the data of the V1 channel graphically.

The data for bit correlation is sampled and displayed with respect to time. Thus pulse and tone duration lengths as well as bit bias may be measured. The bit correlation analysis also allows the accurate determination of baud rates in the case of asynchronous systems with bit errors and propagation dependent distortions.

The time duration of a video line, and thus the display resolution, is set with the sliders in Time per Line. The range is 20,000 μs (0.02 s) to 10,000,000 μs (10 s) per graphical line and sampling takes place in steps of 14 μs. One graphical display line corresponds to the preset time.

Selecting the Start/Stop button controls the effective data sampling.

By moving the mouse cursor a text field is displayed. The value of the positioned segment is continuously displayed in microseconds (μs) and in Baud (Bd) with the graphical cursor. The graphical representation of V1 channel polarity (mark or space) corresponds to the value of the displayed time and the converted baud rate.

Also the correlation can be determined by using bit correlation. The number of time units per line set in Time per Line in addition to the baud rate, constitute the preset values for the correlation.

The following example shows a correlation of 111 bits. The baud rate is 228.66 Bd. Hence the calculation of the total system cycle length is (1 / 228.66) x 111 = 0.4854369 s.

By right-clicking on the display a menu appears. By selecting Zoom In, the mouse cursor changes its shape. By clicking and dragging a field can be enlarged or reduced horizontally and vertically. After the zoom field has been sized, release the mouse button. An enlarged section of the bit correlation is now displayed.

Additionally, several Color schemes are available through the right-click menu.
