All Partial Meas'ments / First Partial Meas'ment
If
is set to a value > 0, this setting allows you to define how the measure-
ment delay is applied:
●
If "All Partial Meas'ments" is selected, the delay time is added before each partial
measurement. For a complete 2 port S-parameter measurement, the delay must be
added twice per sweep point.
●
If "First Partial Meas'ment" is selected, the delay time is added once per sweep
point only, irrespective of the measured quantities and the number of partial mea-
surements. The sweep time increases by the measurement delay times the num-
ber of sweep points.
Tip:
A delay time before the start of each partial measurement increases the accuracy,
in particular for measurements on DUTs with long settling times (e.g. quartz oscillators,
SAW filters). Select "First Partial Meas'ment" if the DUT does not require an additional
settling time due to the interchange of source and receive ports.

Sweep Type Tab
Defines the sweep variable (frequency/time) and the position of the sweep points
across the sweep range.

Lin Freq
In a linear frequency sweep, the stimulus frequency is swept in equidistant steps over
the continuous frequency range. The frequency range (sweep range) and the internal
generator power can be specified in the "Stimulus" settings (see
on page 289). The step width between two consecutive sweep points is con-
stant and given by <Span>/(n - 1) where n is the specified "Number of Points" (n > 1).
