●
According to the sweep axis division into linear, logarithmic and list-controlled
sweeps .
●
According to the sweep direction into upward and downward sweeps .
●
According to the physical basic unit of the Sweep parameter into Frequency, level
and phase sweeps .
●
According to the behavior when the full-scale value is reached into single and
continuous sweeps .
Which sweep parameters are available for the individual generator functions depends
on the characteristics of the respective signal. The following generally applies:
●
A frequency sweep is not possible for multi-tone signals or noise signals.
●
A phase sweep, i.e. the variation in phase shift between Channel 1 and 2, is only
possible for stereo sine waves and should only be performed if both frequencies
are the same.
●
Z-Sweeps are possible if at least two 2 signal parameters of the configured genera-
tor function are sweep-capable.

5.9.1 Activating / Deactivating the Sweep System
The sweep system is enabled and disabled using "Sweep Ctrl ". This simultaneously
defines how the sweep is to be stepped and how the sweep axis is to be defined. For
generator sweeps, this parameter field is located in the generator functions, the ana-
lyzer sweep is available only for the measurement function "RMS Selective" and
