ALC state
to select ALC state.
ALC has three functions: "Off", "On" and "Auto”:
●
AUTO
Automatically turn on or off the ALC function according to the equipment state.
●
On
Enable ALC permanently, regardless of the currently selected mode.
●
ALC Off (S&H)
Deactivate ALC. The instrument switches to Sample & Hold (S&H) state, which still allows
maintaining a constant output level .In “S&H” mode, the signal generator switches for a
short time into CW mode and activates ALC. The ALC adjusts the level to the set value
and the generator holds the value. Then, the generator switches ALC off again and back
to the previous operating mode.
Flatness
The "Flatness" function adjusts the amplitude at specific frequencies by mathematically
adjusting the output by applying user-defined level correction lists. Correction is performed
by the user-defined table values being added to the output level for the respective RF
frequency. With frequencies which are not contained in the list, the level correction is
determined by interpolation of the closest correction values.
The flatness correction function can adjust the RF output amplitude corresponding to the
frequency point within the frequency range of the instrument to compensate for losses in
the cable, or losses caused by other equipment.
