Keysight N9927-90001 User’s Guide 355ERTA (Extended Range Transmission Analysis) Mode - Option 209Configure Measurement SettingsLearn more about Trace Display States in “Trace Display States (SA Mode)” onpage 175.NormalizeNormalize can be used to quickly provide ‘zeroing’ for any of the ERTA (B, R, orG) traces. On the sweep AFTER selecting Normalize, Trace 1 is copied toTrace4. It is then put into View state and subtracted from that input onsubsequent sweeps. Any trace (1, 2, or 3) which is set to process that sameinput (B, R, or G) will therefore be processing normalized measurement data.This continues as long as the frequency span, number of points, and the traceinput (B, R, or G) is NOT changed. If any of these settings change, Normalize isdeactivated.How to Normalize the B trace— Press Meas Setup 4— Then Remote Source— Then Normalize ONSource Tracking Offset and Offset ReversalSource offset tracking is used to offset the Source frequency from the Receiverfrequency by a fixed offset at every tune frequency. This feature is used whenthe DUT contains a frequency converter.How to set Tracking Offset and Offset Reversal— On the Receiver unit, press Meas Setup 4,— Then Remote Source— Then Advanced— Then choose one or both of the following:— Tracking Offset Enter an offset value.— OfsTrkReversal Determines whether Receiver Freq is added to orsubtracted from the Offset Freq.——OFF SourceFreq = Offset + RecFreq. Use to measureUpconverters.——ON SourceFreq = Offset - RecFreq. Use to measureDownconverters. The source sweeps in Reverse direction.The Offset Freq. MUST be larger than the Receiver Stop Freq.
