Sweep condition (frequency [Hz], level [V], level [I], bias [V], bias [I])
Parameter function
High/low limit (HIGH, LOW)
Single point delay (DELAY[s])
3.6.1 Total Point
Set the number of points to be scanned for list sweep, the value range is 1~201;
Parameter setting attributes: enumerated type.
3.6.2 Trigger mode
It is the same as the trigger mode on the measurement setting page.
After the list sweep is triggered normally, the user can interrupt the list sweep process by pressing
the Reset button:
Press Reset once to enter the pause state, and continue scanning at the current point after triggering
again;
Press Reset twice to enter the reset state, and scan from the first point after triggering again;
3.6.3 List mode
Set list 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 list 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.
3.6.4 Sweep condition
Frequency, level, and bias can be set independently, and can also be quickly set to make one of the
conditions remaining relatively regular.
If you are only concerned about the impact of one condition change on the DUT, you can quickly set
other test conditions to the same result, such as a linear change in frequency, and a fixed level and
bias.
Regarding the frequency, level and bias in the sweep condition, you can choose whether to display it
on the test page, touch the title area corresponding to the parameter, and then select ON or OFF on
the corresponding menu.
