"Voltage" Used to activate a level sweep. Which signal parameter is actually
swept (e.g. the level of a single sine-wave line or the total level of a
multi-tone signal) depends on the respective generator function.
"Frequency" Used to activate a frequency sweep. Not possible for noise signals
and multi-tone signals. Which signal parameter is actually swept (e.g.
the frequency of a single sinusoidal line or the center frequency of a
two-tone signal) depends on the respective generator function.
"Phase" Used to activate a phase sweep. Possible only for the generator func-
tion "Stereo Sine ".

5.9.3 Two-Dimensional Sweep
For two-dimensional sweeps, 2 (different) parameters are varied; the first parameter is
selected as the x-axis, the second parameter is selected as the z-axis.
Both axes (sweep dimensions) can each consist of max. 1024 individual points, which
means that each axis is divided into max. 1023 steps.
As soon as all of the points on the x-axis have been processed, the analyzer returns to
the 1st X-value and simultaneously sets the next Z-value. When the sweep cycle for
the last Z-point has been completed, the X and Z-values are reset to their original start
values.
The last 20 sweep cycles (scans) are available as the data set. If the z-axis contains
more than 20 points, only the last 20 scans can be stored as a trace data record. Simi-
larly, only the last 20 scans are retained if the graph is rescaled.
A two-dimension continuous sweep started using [START ] is terminated after the
sweep cycle of the last Z-point.
Z-axis
Select the second sweep parameter for the two-dimensional sweep. Is simultaneously
used to enable or disable the two-dimensional sweep. Only visible for activated gener-
ator sweep system.
Note: With the DC generator function, only one parameter can be swept. The ""z-axis""
parameter field (and therefore a two-dimensional sweep) is not available in this case.
