"Ch1&2" The frequency can be entered separately for Channel 1 and 2. There
is no fixed phase relationship between the channels.
With the frequency sweep, the frequency of Channel 1 is swept but
Channel 2 remains unchanged.
Note: If Gen Track is selected as the measurement time in the ana-
lyzer, measurement channel 1 follows the frequency of generator
channel 1 and measurement channel 2 follows the frequency of gen-
erator channel 2.
Remote command:
SOURce:FREQuency:SELect

Volt Mode
This setting determines the setting of the level for channels 1 and 2. The maximum
value depends on the configured DC offset. In the analog generator, the maximum total
voltage also depends on the settings for Output Type and Max Voltage in the Genera-
tor Config panel.
"Ch2/1" The levels of Channel 1 and 2 have a fixed ratio relative to each
other.
With the level sweep, this ratio remains constant.
"Ch1&2" The level can be set separately for Channel 1 and 2.
With the level sweep, the level of Channel 1 is swept but Channel 2
remains unchanged.

Sweep Ctrl
Used to activate the sweep system. The frequency, phase or level of the signal can be
varied within a selectable range from the start to the stop value. The Freq Mode and
Volt Mode settings determine how frequencies and levels are changed during the
sweep.
If frequency, phase or level is selected as the x-axis, the measured values can be dis-
played as a curve in the Sweep Graph graphical window.
Sweep points: Linear or logarithmic between Start and Stop or read out of the file.
Forwarding: Automatic in a defined timeframe or synchronized to the measurement
time of the analyzer. All setting parameters of the sweep system are described in detail
in
Chapter 5.9, "Sweeps" , on page 285.
Frequency
The frequency is identical for both channels (Freq Mode F&Ph).
Note: If Gen Track is selected as the measurement time in the analyzer, the measure-
ment time and generator frequency are synchronized. The synchronization is per-
formed in such a way, that the signal periods recorded during the measurement time
contain an integer number of samples. If necessary, the generator frequency is modi-
fied slightly.
