1. Keypad operation
Press LEVEL-> ALC State to expand the drop-down box, then rotate the knob or press
the up and down direction keys to select ALC state.
2. Touch operation
Click on SHORTCUT->LEVEL->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 period of 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.
2.2.4 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. If there is only
one point, it will not perform correction.
The flatness correction function can adjust the RF output amplitude corresponding to the
