1. Turn on Sweep mode modulation using the
SOURce[1]: 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]:FREQ:STAR
and SOURce[1]: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]:FREQ:CENT
and SOURce[1]: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]:SWE:SPAC command.
