The Measure_duts subroutine.
400
Turn laser source on.
420 to 580
FOR-NEXT loop to step through and measure each of the
8 devices-under-test.
440 to 450
Create the HP-IB commands to select the input and output
switch positions to measure the current device-under-test.
For example, if Current_dut=3 then In_switch$ and
Out_switch$ would equal "ROUTE:LAYER1:CHANNEL
B3". Note that since the switches are 1x8, it is not
necessary to specify the position of the A ports.
500 to 550
Use the *WAI command to ensure both switches have
settled.
570 to 610
Read the optical power from the optical multimeter. If this
power is less than Min_power then print appropriate error
message to screen.
630
Increment Meas_count.
640
Return to calling line.

End_prog subroutine. Turn off time-initiated branching
and end program.
