Selecting Sweep Type
To select the sweep type:
1. Press Sweep Setup > Sweep Type.
2. Press the desired softkey to select the sweep type: Lin Freq | Log
Freq | Segment | OSC Level | DC Bias | Log DC Bias.
When selecting the OSC Level ,oscillator level as a
sweep parameter, follow the steps shown in Selecting Unit for
Oscillator Level (Voltage or Current)” to select sweeping by
voltage or current level.
When selecting the dc bias as a sweep parameter, proceed
to the setting shown in Setting and Applying dc Bias
.
See Using Time as Sweep Parameter (Zero Span Sweep)
for the measurement with time as a sweep parameter
(zero span measurement).
The sweep parameter is set for all traces. It is not
necessary to select an active trace or to verify the current
selection before setting the parameter.
Setting Sweep Range
Sweep range can be set by specifying either start and stop values or center
and span values.
The measurement range can be set to trace A and trace B
in common. It is not necessary to select an active trace or to verify the
current selection before setting the range.
