3.7.4 Sweep point
Here is the number of points to be scanned. There are five groups of 51, 101, 201, 401, 801 to
choose from.
3.7.5 Sweep Type
The sweep type is mainly used to set the conditions of the trace sweep, that is, to plot the test results
according to the selected condition parameters, so it involves the type of condition parameters, the
start size and the stop size of the condition change.
Sweep Type
Set the main conditions corresponding to the sweep curve, namely frequency [Hz], level [V], level
[A], bias [V], bias [A];

Freq[Hz]
The condition changes within the
specified interval (between start and
stop), and record the corresponding
parameter results after changing in a
linear or logarithmic relationship

Starting conditions
After selecting the sweep type, to set the start size and stop size of the corresponding conditions;
that is, the start and stop points of the trace sweep.
3.7.6 Trace mode
Set the trace sweep mode, sequence mode or single step mode.
Parameter setting attributes: enumerated type.
Sequence
mode
When the trigger is valid, sweep sequentially from the
first point to the last point
Single
step mode
When the trigger is valid, only one point can be tested at a
time
Note: The effect of the trace mode is mainly reflected in the single trigger mode. If it is the
continuous trigger mode, the test process of the two modes will be visually different.
3.7.7 X Format
This area is used to change the coordinate mode of sweep, mainly for the abscissa.
Linear
The sweep condition parameters are linearly distributed in the start
and stop ranges
Logarithm
The sweep condition parameters are distributed in a logarithmic
