Calibration ALC TABLE
For vector modulation or digital modulation, SMIQ is operated with the internal level control switched off.
In mode ALC MODE - SAMPLE & HOLD, the level is recalibrated for each level or frequency setting. In
mode TABLE, the latter does not apply since the necessary input values are taken from a table. This
table can be regenerated using LEARN TABLE
. This is required to attain an optimum level accuracy
for the given operating temperature.
