Using the Power Meter Linearity Verification Tool
158 IQS-12004B
Setting Up the Acquisition Parameters
Setting Up the Acquisition Parameters
The linearity verification is made by comparing results obtained when
attenuating the power level on a power meter to be tested and a reference
power meter.
The power direction can be decreasing, increasing or both (a specific trace
will be displayed and values will be added to the results grid for each of the
power directions).
If you select both directions, the decreasing values will be displayed first.
The increasing values will be added just after.
