Chapter 4 Remote Interface ReferenceFrequency Sweep CommandsFrequency Sweep CommandsSee also “Frequency Sweep,” starting on page 94 in chapter 3.Sweep OverviewThe following is an overview of the steps required to generate afrequency sweep. The commands used for frequency sweep are listed onthe next page.1 Select the waveform shape, amplitude, and offset.Use the APPLy command or the equivalent FUNC:SHAP, VOLT, andVOLT:OFFS commands to select the function, amplitude, and offset ofthe sweep waveform. You can select a sine, square, triangle, ramp,or arbitrary waveform.2 Select the start and stop frequencies.Use the FREQ:STAR and FREQ:STOP commands to set the start andstop frequencies respectively.To sweep up in frequency, set the start frequency < stop frequency.To sweep down in frequency, set the start frequency > stop frequency.3 Set the sweep time.Use the SWE:TIME command to set the number of seconds required tosweep from the start frequency to the stop frequency.4 Select the sweep mode.Use the SWE:SPAC command to select linear or logarithmic spacing.5 Select the sweep trigger source.Use the TRIG:SOUR command to select the source from which thesweep will be triggered.6 Enable sweep modulation.Use the SWE:STAT ON command to enable the sweep mode.170
