It is necessary to calibrate the test system before you run the first test, in
order to ensure that test results are consistent from run to run. Provided
the equipment has achieved thermal stability before the calibration is
started (typically after 30 min of warm-up), the thermal environment is
stable, and no system elements have been exchanged, the calibration is
very stable and may only have to be repeated once a week or even less
frequently. The calibration interval depends on the degree of accuracy
desired. If the station is not calibrated prior to a DUT test, the results of the
previous calibration will be used for the current tests.
The calibration, receiver and transmitter test procedure groups can be
selected globally by clicking on the check box at the top of the group.
Alternatively, an individual test procedure can be selected by checking the
specific selection boxes in front of the tests. Only the procedures which are
selected will be executed.
Most calibration and test procedures as well as the groups containing
them have parameters that control the details of how the procedures are
run. In compliance mode most of these parameters are read-only. In
expert mode almost all parameters can be modified. First, select a specific
calibration or test procedure or one of the groups contained in the N5991
procedure tree. The parameters are displayed in a property list on the
right-hand side of the screen (See
only before the execution of the procedure subgroup or procedure is
started. The test parameters selected are listed in the MS Excel/HTML test
results worksheets.
