The lower entry value takes account of the current start and stop values and is auto-
matically limited so that regardless of the sweep direction a maximum of 1024 mea-
sured values can be recorded. Values of less than 0.1% cannot generally be entered.

5.20 Sweep Options
Besides the measurement system, the R&S UPP is also equipped with a comprehen-
sive sweep system. This sweep system is enabled as a generator sweep system by
activating a generator sweep or as an analyzer sweep system by activating the RMS
selection sweep, and then takes control of the measurement system.
When a sweep system is activated, sweeps are started and also stopped in manual
operating mode using the [START ], [SINGLE ] and [STOP/CONT ] keys or buttons.
Starting or restarting a sweep (via [START ]) also causes certain generator functions to
restart:
●
The sine-burst burst signal is reset, that is, it starts with the burst phase or burst on
delay.
●
The Play function starts again at the first sample in the WAV file.
●
The Arbitrary function also starts again at the beginning.
5.20.1 Overview of Sweep Options
The following information refers to an activated sweep system , i.e. a sweep is activa-
ted in either the generator or the analyzer.
Sweeps are measurement cycles in which the individual measurements are triggered
by predefined generator and analyzer settings. The generator and analyzer sweeps
can be defined either by entering the start value, stop value, spacing and points/step or
by specifying a sweep list. Both methods ultimately define a
table of settings (x-axis)
which is processed when the sweep is started.
A one-off sweep is referred to as a single sweep and a continuously repeated sweep
as a continuous sweep .
The active sweep system is controlled
●
explicitly using [START ] (Ctrl F5), [SINGLE ] (Ctrl F6) and [STOP/CONT ] (Ctrl F7)
●
implicitly by means of "termination events". These are events (user entries) which
invalidate the current measurement and, therefore, the current sweep, i.e. changes
in the generator, analyzer or filter bank. Following a termination event, the current
sweep is restarted automatically. This ensures that the recorded data sets are
based on the same settings.
It is not possible to control the measurement system if the sweep system is activa-
ted. Exception: When a sweep has been terminated, [STOP/CONT] or a termination
