5.2 Test Procedure (ZVM & ZVK)
The rated specifications of the network analyzer are checked after a warm-up time of at least one hour.
Only this warmup ensures that the specifications are complied with.
The values stated in the following are not guaranteed. Only the data sheet specifications shall be bind-
ing.
In order to guarantee the specified data, the measured value has to be < specification - expanded un-
certainty (k = 2, confidence level of 95%).
The expanded uncertainty (k = 2) obtained with the proposed measuring equipment / test procedures is
given in the test record. Influences, which are exclusively within the user’s responsibility (e.g. cable at-
tenuation in harmonics measurements), are not taken into account in the specified measurement un-
certainty and should be at least estimated by the user.
In case of a deviating test configuration, the user has to calculate the corresponding measurement un-
certainties.
