Switching Between Frequency Domain And Pulse Pro Le Domain - HP 8510 User Manual

Switching Between Frequency Domain and Pulse Profile Domain
The domain in which the measurement calibration was performed is not part of the cal set
limited instrument state. This means that, for example, a cal set created in the frequency
domain could be turned on for a pulse pro le domain measurement with no message to the
operator. Except for the pulse pro le calibration procedure in the frequency domain using
Frequency List, a cal set should only be used in the domain in which it was created.
Press the following keys to switch between the frequency domain and the pulse pro le domain.

This sequence makes certain that the cal set applies to the domain in which it was created.
Another method is to save a number of instrument states, each with the appropriate domain
and cal set, then simply recall the desired instrument state.
If a cal set created in the pulse pro le domain is turned On while in the frequency domain, it
is treated as if the calibration were performed using step sweep with the minimum frequency
span. The pulse pro le domain error coecients are applied to di erent frequency points,
resulting in trace errors.
Also, if a cal set created in the frequency domain is turned On while in the pulse pro le
domain, the frequency is set to the start frequency of the frequency domain cal set and the
frequency domain error coecients are applied to each corresponding point in the pulse pro le
domain. This also results in trace errors.
