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
Configuring the Instrument
