HP 8510 User Manual

5. Select the maximum number of points required for the measurement, then perform the
appropriate measure- ment calibration.
Note that the HP 8510 pulse output is set to the active state (RF always On) during
measurement of the calibration standards. For external triggering, the pulse mo dulation is
operating during the calibration, so the pulse width or time span cannot be changed after
calibration.
6. For the next pulse prole frequency rep eat this sequence.
With several cal sets created in this way,you can select each pulse prole frequency in turn by
recalling the corresponding cal set.
Frequency Domain Using Frequency List
In the above measurement calibration pro cedure it is necessary to p erform a separate
calibration for each pulse prole frequency. This is not a problem for simple resp onse-only
calibrations, but when accuracy considerations require the use of 1-Port or 2-Port calibrations,
connecting the necessary sequence of standards rep eatedly can b e tedious. As an alternative,
the frequency list feature allows the standards to be connected once for all pulse prole
frequencies.
