Optimizing PerformanceUsing External Leveling (N5183A Only)Recommended Equipment• Agilent 8474E negative detector• Agilent 87301D directional coupler• cables and adapters, as requiredFigure 5-22 Typical External Leveling Setup using a Directional CouplerALC INPUTNegative DetectorRF OUTPUTLeveled SignalSignal GeneratorAmplifierCouplerConfiguring the Carrier1. Press Preset.2. Set the carrier frequency.3. Set the power level to 0 dBm:• If the signal generator has no output attenuator (no Option 1E1) or it has Options 1E1 and532 or 540 installed:Press AMPTD > 0 > dBm.• If the signal generator has Options 1E1 and 520, set the output attenuator to zero dBm:a. Press AMPTD > Atten/ALC Control > Atten Hold Off On to On.b. Press Set Atten > 0 > dB.c. Press Set ALC Level > 0 > dBm.Selecting External LevelingPress AMPTD > Leveling Control > Leveling Mode > Ext Detector.Determining the Signal Generator’s Amplitude RangeThe maximum output amplitude is frequency dependent. So if you are using multiple frequencypoints and there is a need to know the maximum output amplitude for each frequency point, refer tothe “Amplitude” section of the MXG Data Sheet. Then use this procedure to determine the maximumamplitude for each band.Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide 109
