Sequence.
Follow the steps below to create a sequence:
1. Create more than one block (pattern data delimited by block delimiter) on
the pattern memory by doing the following:
a. Create the pattern data using the procedures described previously in
Pattern Data.
b. Change the block name with EDIT
!
Block
!
Rename current
block.
c. Move the cursor to the data point next to the end of the pattern data by
changing the value in the Cursor on the screen.
d. Mark the block delimiter with EDIT
!
Block
!
Add block delimiter
here. This creates a new block. The block must have a unique name,
which you can enter at this time.
e. Create the next block pattern using the procedures described previously
in Pattern Data.
f. Repeat Step c through Step e until you have created all the blocks that
you need.
2. Create a sequence table by doing the following:
a. Open the sequence editor with EDIT
!
Make Sequence.
b. If you need, create subsequence(s) with EDIT
!
Make Sequence
!
Special
!
Edit Sub-Sequence
!
New.
c. Compose the lines by inserting the blocks and/or subsequences with
EDIT
!
Make Sequence
!
Insert.
d. Define the control conditions in each line with EDIT
!
Make
Sequence
!
Repeat Count and/or the functions of EDIT
!

Set Enhanced Control.
Do the following steps to configure the instrument hardware and set the output
parameters:
1. Assign data bits (DATA0 and DATA1) to output channels (CH0 and CH1)
with SETUP
!
Output Condition
!
Assign Condition. By default,
DATA0 and DATA1 are assigned to CH0 and CH1, respectively.
2. Set the pulse high and low levels with SETUP
!
Level Condition.
3. Set the delay with SETUP
!
Timing Condition.
4. Set the output frequency with SETUP
!
Clock.
