CALIBRATION

This procedure provides the steps necessary to perform ALC Slope

 

calibration. The ALC Slope DAC is calibrated to adjust for an increas-

 

ing or decreasing output power-vs-output frequency in the analog

 

sweep mode. The ALC Slope DAC has two calibrations—one for fre-

 

quencies ￿2 GHz and one for frequencies >2 GHz.
