Frequency Domain Using Frequency List - 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 modulation 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 repeat 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 procedure it is necessary to perform a separate
calibration for each pulse pro le frequency. This is not a problem for simple response-only
calibrations, but when accuracy considerations require the use of 1-Port or 2-Port calibrations,
connecting the necessary sequence of standards repeatedly can be tedious. As an alternative,
the frequency list feature allows the standards to be connected once for all pulse pro le
frequencies.
Perform the calibration as follows.

for each pulse pro le frequency to be measured. Each segment is de ned such that the
start and stop frequencies are identical and the number of points in each segment is the
number of points to be displayed in the pulse pro le measurement. For example, the
following sequence creates a frequency list to measure four pulse pro le frequencies, of 51
points each.
