3 Instrument Configuration84 Keysight U8903A User’s GuideThe measurement bandwidth selection is shown as follows.Figure 3-9 Measurement band width selectionMeasurement timeThe measurement time can be set to Gen Track or a fixed duration ranging from0.0078125 s (equivalent to a measurement rate of 128 readings/s) to 1 s. Whenthe measurement time is set to Gen Track, the analyzer will vary the measurementtime according to the generator frequency for the same channel. This is usefulwhen making sweep measurements as the measurement time will be optimizedfor fast sweeps. However, Gen Track works only if the signal is looped back fromthe U8903A output to its input.
