User Manual 301/302 
shows the relationship between links and sequences. 
 Sequences   Links 
   1    4096 
   2    2048 
   4    1024 
      8     512 
   16    256 
For example, if you plan to use 5 sequences, your choice must be 8 
sequences and the maximum number of links that you’ll be able to 
specify for each sequence is 512. 
Use the following command to specify the number of sequences you 
intend to use: 
MSEQuence:SIZE <size> 
Size specifies the number of sequences. Numbers range from 1 
through 16. The default value is 1, therefore if you do not plan to use 
more than one sequence in your test setup, there is no need to use 
this command at all. 
The next step is to start defining the active sequence. If you have only 
one sequence, you can go ahead and start downloading its sequence 
table. If you planned to use more than one sequence, you first have to 
tell the instrument, which of the sequences is active for downloading 
its table. 
To select the active sequence for table download use the following 
command: 
SSEQuence:SELect <sequence_number> 
After you use this command, sequence definitions will apply to the 
sequence number you selected with the above command. 
You can now start downloading sequencer steps. Each step has two 
parameters: segment number and repeat counter. The segment 
number specifies which segment will be linked, and the repeat counter 
specifies how many times the segment will loop. 
There are two ways to download a sequence table to the 301/302: 1) 
Using standard ASCI commands and 2) Using binary fast download 
command. If your application requires downloading just a few steps, 
you can use the standard ASCII table downloads, as shown below. In 
cases where large tables have to “dumped” to the generator and 
where timing is critical for the system, you can use the Fast Binary
