Frequency Sweep

Sweep Mode
You can sweep with either linear or logarithmic spacing.
For a
linear
sweep, the waveform generator varies the output frequency
linearly
during the sweep. For a logarithmic sweep, the waveform generator
varies the output frequency logarithmically.
The selected mode does not affect the sweep return (from stop to start, if
one is set). The sweep return is always linear.
• Sweep mode: Linear (default), Logarithmic, or List.
• Front-Panel Operation: After enabling sweeps, press the Linear
softkey again to toggle between the linear or log mode.
• Remote Interface Operation:
[SOURce[1|2]:]SWEep:SPACing {LINear|LOGarithmic}
Sweep Time
The sweep time specifies the number of seconds required to sweep from
the start frequency to the stop frequency.
The number of discrete
frequency points in the sweep is automatically
calculated by the
waveform generator based on the sweep time.
• Sweep time: 1 ms to 250,000 seconds. The default is 1 second.
• Front-Panel Operation: After enabling sweeps, press Sweep Time.
Then use the knob or numeric keypad to enter the desired sweep
time.
• Remote Interface Operation:
[SOURce[1|2]:]SWEep:TIME {<seconds>|MINimum|MAXimum}
