The time interval between two consecutive trigger pulses must not be smaller than the
minimum measurement time per measurement point. See
Remote command:
POINt
Time
"Time" sweeps are performed at constant frequency and stimulus power. A single sweep
extends over a specified period of time. The sweep time is defined via "STIMULUS >
STOP"; see
chapter 3.1.4.2, "Stimulus and Sweep Types"
, on page 16. The time intervals
between two consecutive sweep points are calculated according to <Stop>/(n - 1) where
n is the selected "Number of Points". The frequency ("CW Frequency") and internal
source power ("Power") are fixed. Both can be defined in the "CHANNEL > SWEEP >
Sweep Params" tab.
A "Time" sweep corresponds to the analysis of a signal over the time; the function of the
analyzer is analogous to an oscilloscope. In a Cartesian diagram the measurement result
is displayed as a trace over a linear time scale. The following example shows a "Time"
sweep with a DUT that does not markedly change its transmission characteristics over
the time.
Tip: Sweep time
The minimum sweep time depends on the number of measurement points, the mea-
surement bandwidth, the delay time before each partial measurement and the number
of partial measurements required for each measurement point. The analyzer estimates
this time, taking into account the current measurement settings.
If the total sweep time entered via "STIMULUS > STOP" is smaller than the estimated
minimum sweep time, the entered value is increased automatically.
Equidistance of sweep points
The analyzer tries to keep the time intervals between any two consecutive time sweep
points equal: The time sweep samples are equidistant. Equidistance also holds for
sweeps which range over several channels.
