Part 3: Using Mobile Van and E6474A Sequencer for measurements

1 Run the Agilent E6474A application. (Refer to the E6474A

User’s Guide and online help for more information).

2 After configuring your hardware add the phone device to

your sequence in the sequencer system panel.

3 Add a parallel sequence node (refer to Figure 30).

Figure 30 Parallel Sequence example

4 Check that the sequence nodes and tests are configured

with these properties:

• Parallel node properties (refer to Figure 31)

a Number of times to run = Infinite

b Wait time after completion = 40

This is the time between each measurement session/call

to be initiated by the application. 40 seconds is a safe

duration to ensure that the office unit recovers from an

abnormal call, and is ready to make measurements

again.

c Minimum repeat duration = 0
