ALC SLOPE
CALIBRATION Models 683XXB with Firmware Version 1.01 to 2.00
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.
