You can extend this process of calling the next sequence from the last line of the present sequence to 6
internal sequences, or an unlimited number of externally stored sequences.

Loop Counter Example Sequence

This example shows you the basic steps necessary for constructing a looping structure within a test
sequence. A typical application of this loop counter structure is for repeating a specific measurement as you
step through a series of CW frequencies or dc bias levels. For an example application, see
Measurements" on page
1. To create a sequence that will set the initial value of the loop counter, and call the sequence that you
want to repeat, press:
Seq NEW SEQ/MODIFY SEQ

To create a second sequence that will perform a desired measurement function, decrement the loop
counter, and call itself until the loop counter value is equal to zero, press:
