You must check the Also collect phase data checkbox in the Collection
Specification dialog box so the data collector collects phase at orders.
6. Select the storage specification.
The first measurement definition is now complete.
7. If you want to create more than one measurement, copy the measurement
definition by selecting the correct row and choosing Edit > Copy.
8. Move down to the next empty row in the measurement definition
spreadsheet, and choose Edit > Paste to paste the copied measurement
definition.
9. Edit the new measurement definition by changing the measurement filter.
10. Select a band filter centered on the next order.
11. Repeat steps 6 and 7 to create measurement definitions for the desired
orders.
You can then include these measurement definitions in a list and load it to
the data collector. Remember that you must have a trigger signal to collect
magnitude and phase at an order.
