Hints on Editing Pattern Data
The block editing functions, apart from Insert and Delete, do not affect
data bits beyond the current L
AST
bit. Therefore, you can use the A
DDR
and L
AST
parameters to define the block of bits you want to edit.
Remember, however, that the L
AST
parameter also defines the length of
the pattern generated at the outputs.
Example
You are currently generating a 48-bit pattern on output 1 and now want to
fill bits 10 to 20 with data value 1. On the Pattern screen:
1
If necessary, move the cursor to UPDATE and select U
PD
O
NCE
to
prevent the data edits from affecting the pattern currently being
generated at the output.
If NO UPD is already selected or if it is not important if the pattern is
disturbed during the editing, you can ignore this step.
2
Adjust A
DDR
to 10.
3
Adjust L
AST
to 20
If UPDATE is still active, the pattern at the output will now be
automatically reduced to 20 bits in length.
4
Move the cursor to CH1 to access the block editing functions for
output 1.
5
Use the MODIFY knob to select F
ILL
1 from the list of functions.
6
Press ENTER to fill bits 10 to 20 with data value 1.
If UPDATE is still active, the pattern at the OUTPUT will now change
automatically.
7
Adjust L
AST
back to 48 to reset the pattern length to 48.
If UPDATE is still active, the pattern at the OUTPUT will now be set
to a length of 48 bits.
8
If necessary, move the cursor to NO UPD and press ENTER to update
the pattern being generated at the OUTPUT (or select U
PD
C
ONT
).
