Setting up Patterns 7
Bit Coding
The following figure shows the pattern edit pane with a bit coded pattern
in binary (BIN) mode:
The bottom of the pattern edit pane indicates the position of the selected
symbols and buttons to edit them. These buttons are only available when
you create a pattern in bit coding and the data view mode is binary (BIN).
You can use these buttons to:
0 - Set data 0
1 - Set data 1.
X - Click this toggle button to add/remove mask on a data.
S - Click this toggle button to add/remove squelch on a data.
You can use the buttons as well as the keyboard keys to
move the pointer position to the left, right, up and down in the pattern.
The bottom of the pattern edit pane also displays the symbol number
which indicates the number.
You can use the Settings Window to enhance the visualizations of the
current pattern. For details, refer to “Settings Window” on page -412.
To encode a bit coded symbol 1, 2 or 3 bits are needed. This depends on
the use of mask and squelch:
