Introduction
This documentis intended for use with the HP 8510B/C Option 008 Network Analyzer
and is a supplement to the HP 8510B/C Operating and Programming manual. It contains
descriptions of the pulsed-RF network analyzer system features for measurements in the
frequency domain and in the pulse prole domain. With resp ect to the standard, swept CW
system, op eration of the pulsed-RF system is identical except that the measurement is made
at a sp ecic, known time during each pulse. For information about network analysis, please
refer to HP Pro duct Note 8510-10, HP 8510B Intro ductory User's Guide, for an intro duction
to using the front panel for measurement setup, measurement calibration, and basic network
measurements.
