1. Turn on Sweep mode modulation using the
SOURce[1|2]: SWE:STAT ON command.
2. Use the APPLy command to select the waveform shape.
Alternatively, the FUNC, FREQ, AMPl, and DCOffs
commands can be used to create a waveform with a
designated frequency, amplitude and offset.
3. Set the frequency boundaries by setting start and stop
frequencies or by setting a center frequency with a span.
Start~Stop Use the SOURce[1|2]:FREQ:STAR and
SOURce[1|2]:FREQ:STOP to set the start
and stop frequencies. To sweep up or
down, set the stop frequency higher or
lower than the start frequency.
Span
Use the SOURce[1|2]:FREQ:CENT and
SOURce[1|2]:FREQ:SPAN commands to
set the center frequency and the frequency
span. To sweep up or down, set the span
as positive or negative.
4. Choose Linear or Logarithmic spacing using the
SOURce[1|2]:SWE:SPAC command.
Select Sweep
Time
Select the sweep
trigger source
Select the marker

5. Choose the sweep time using the
SOURce[1|2]:SWE:TIME command.
6. Select an internal or external sweep trigger source using
the SOURce[1|2]:SOUR command.
7. To output a marker frequency from the trigger out, use
The SOURce[1|2]:MARK:FREQ command. To enable
marker frequency output, use the SOURce[1|2]:MARK
ON command.
The marker frequency can be set to a value within the sweep
span.
