Sweep Overview
The following is an overview of the steps required to generate a sweep.
The commands used for sweep are listed on page 205.
1 Select the waveform shape, amplitude, and offset.
Use the APPLy command or the equivalent FUNC, FREQ, VOLT,
and VOLT:OFFS commands to select the function, frequency, amplitude,
and offset. You can select a sine, square, or ramp waveform (pulse, noise,
dc, and arbitrary are not allowed).
2 Select the frequency boundaries of the sweep.
You can set the frequency boundaries using one of two methods.
a Start Frequency/Stop Frequency: Use the FREQ:STAR command to
set the start frequency and the FREQ:STOP command to set the
stop frequency.
To sweep up in frequency, set the start frequency < stop frequency.
To sweep down in frequency, set the start frequency > stop frequency.
b Center Frequency/Frequency Span: Use the FREQ:CENT command
to set the center frequency and the FREQ:SPAN command to set the
frequency span.
To sweep up in frequency, set a positive span.
To sweep down in frequency, set a negative span.
3 Select the sweep mode.
Use the SWE:SPAC command to select linear or logarithmic spacing for
the sweep.
