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 “Fixed IF Mixer Measurements” in Chapter 3.

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:

This will create a displayed list as shown:

SEQUENCELOOP

Start of Sequence

LOOP COUNTER 10x1

DO SEQUENCE SEQUENCE 2

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,

This will create a displayed list as shown:

SEQUENCELOOP

Start of Sequence

Trans: FWD s21 (B/R)

SCALE/DIV

AUTO SCALE

MKR Fctn

SEARCH MAX

DECR LOOP COUNTER

IF LOOP COUNTER <>O THEN DO

SEQUENCE 2

To run the loop sequence, press:
