Hi, all

The advantest network analyzer(NA) is being used, however, we are considering switch to agilent NA.

cost and sweep time are the main concerns.

Here are the questions
(1) in the sweep mode, there are stepped, swept, high speed swept.
However, in current Advantest model, there is the linear/log/power modes.
What are the differences?

(2) from Agilent NA datasheet, it is found that sweep time will change with calibration
condition. E.g., un-cal, least time, 2 port cal. normal time, 4 port cal. long time.
However, as for the advantest model, it is confirmed that there is no much differences
between the calibration conditions.

Your comments are highly appreciated!
