Entering the Phase
Use The multi-sinewave is generated by periodically playing back a sequence of
signals at a repetition frequency which corresponds to the frequency
resolution (spacing). All sinewave tones have the entered phase position at
the beginning of the sequence.
The mutual phase position of the individual components influences the crest
factor. You can change the crest factor by selecting the appropriate phase.
Note: The setting is always valid for both channels (Ch 1&2).
Selecting the
signal component 1. Select a signal component in the parameter field using the
6 or 5
cursor keys .
The line (signal component) is highlighted.
Entering the phase
2. Press the function key in the submenu.
An entry field containing the currently applicable setting is displayed. The
default setting is “0 grd“.
3. Enter a new value ( Ê 5-65).
The permissible entry range is:
-180 grd < PHASE < +179.9 grd
The new setting is stored and displayed in the parameter field.
Entering the Relative Signal Amplitude
Use You can enter the amplitude ratio of the individual signal components in dBr
refering to the reference value (
Ê 6-128).
Note: The setting is always valid for both channels (Ch 1&2).
Selecting the
signal component 1. Select a signal component in the parameter field using the
6 or 5
cursor keys .
