Optimizing PerformanceUsing Flatness CorrectionRecalling and Applying a User Flatness Correction ArrayThe following example assumes that a user flatness correction array has been created and stored. Ifnot, perform the Example: A 500 MHz to 1 GHz Flatness Correction Array with 10 CorrectionValues on page 95.1. Preset the signal generator.2. Recall the desired User Flatness Correction file:a. Press AMPTD > More > User Flatness > Configure Cal Array > More > Preset List > Confirm Preset.b. Press More > Load/Store.c. Highlight the desired file.d. Populate the user flatness correction array with the data contained in the selected file:Press Load From Selected File > Confirm Load From File.The user flatness correction array title displays User Flatness: Name of File.3. Apply the correction data in the array to the RF output: Press Return > Flatness Off On to On.98 Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide
Optimizing PerformanceUsing Internal Channel Correction—(Requires Option U01 or Greater)Using Internal Channel Correction—(Requires Option U01 or Greater)The internal channel correction feature corrects the 100 MHz baseband bandwidth flatness and phasefor arbitrary center frequencies. This feature is off by default, as the switching speed performance ofthe instrument is impacted when this feature is on.This calibration should be run when the ambient temperature has varied by at least ±5 degreesCelsius from the ambient temperature at which the previous calibration was run.NOTEThere is an internal calibration routine that can be run to collect correction data for boththe baseband and RF magnitude and phase errors over the entire RF frequency range on anyunit with options 651, 652, or 654. The internal channel correction cannot be turned on untilafter the correction has been executed once.For new instruments, shipped with firmware version A.01.60 and above, the internal flatnesscorrection calibration has already been run.When this feature is off, the box will behave as it always has. When this feature is on, the internalI/Q path is active, the I/Q Correction Optimized Path is RF Output, and the frequency is changed bymore than 1 kHz, the firmware will calculate a channel correction filter ±50 MHz about the specifiedfrequency. For List/Sweep, the calculation will be done prior to the first sweep using the specifiedfrequencies when either waveform sweep is active or the baseband is on and the instrument isoptimized for the internal path. This calculation will cache corrections for up to the maximumnumber of cache points (256). For list/sweep, the sweep will pause and recalculate the correctioncaches before running again.CAUTION In the case of arbitrary frequency switching, once the correction cache is full (256unique frequency points), the oldest frequency corrections will be forgotten as newfrequencies are selected.Whenever I/Q Timing Skew, I/Q Delay, Quadrature Angle Adjustment, or the IntEqualization Filter is adjusted, all caches are forgotten.Additional characteristics of the internal channel correction:• When the internal channel correction is on, arbitrary frequency switching while the baseband ison will take up to an additional 290 ms (72 ms typical) the first time that frequency is specified.After the first time that a frequency is selected, switching to that frequency again takes anadditional 1 ms.• If a frequency sweep is activated, then the calculation and caching will occur up front for thefirst 256 unique frequencies, and all additional unique frequencies will have the characteristics ofarbitrary frequency switching.• If the I/Q Correction Optimized Path softkey is set to Ext I/Q, then only the baseband correctionswill be applied and the frequency switching will be unaffected.• If active, the ACP Internal I/Q Channel Optimization filter and the Equalization filter, will beconvolved with the internal channel correction. A hamming window is applied and the resultingfilter will be truncated to 256 taps.Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide 99
