Sweep Overview
The following is an overview of the steps required to generate a
frequency sweep. The commands used for frequency sweep are listed on
the next page.
1 Select the waveform shape, amplitude, and offset.
Use the APPLy command or the equivalent FUNC:SHAP, VOLT, and
VOLT:OFFS commands to select the function, amplitude, and offset of
the 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 and
stop 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 to
sweep 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 the
sweep will be triggered.
6 Enable sweep modulation.
Use the SWE:STAT ON command to enable the sweep mode.
