Calibration Requirements
Using A veraging
F or all calibrations , use the same or greater averaging factor than will be used for the
device measurement. In general, use an averaging factor of 8 or 16 for most measurements .
Hewlett-P ackard recommends that you increase the averaging factor for the isolation portion
of the calibration (in RCS calibration this is the background calibration). This can be easily
accomplished by turning A veraging ON before beginning the calibration, then leaving averaging
factor as the active function during the calibration.
If you are using averaging
If averaging is ON during calibration, then the correct number of measurements needed
to provide fully averaged data are automatically taken. F or Ramp sweeps this means that
n+1 sweeps , where n is the current averaging factor , are taken. F or Step , Single P oint, or
Frequency List, each data point is averaged n times (where n is the selected number of
averages).
