When I perform Thru measurement in SOLT cal, the E5071C will meas 2 times, that is trigering 2 times in each port, while it just does a single meas in S,O,L. I wonder is it normal?
You are seeing a difference because the SOLT cal is a multi port cal, SOL on each port and then a thru between the two ports. SOL cal is just a one port reflection cal without the additional thru standard so the Network Analyzer doesn't need to make as many measurements for a 1 port reflection cal as it does for a 2 port SOLT cal.
Let me know if you have any further questions.
Thanks a lot for your reply, but I think maybe you have made a mistake for my point of view. I know that when
the data of thru is gathered, both ports need to be triggered, that is port one is triggered for gathering
S11 and S21, while port two is triggered for gathering S12 and S22. Howerver, I cannot press 'done' to finish my
calibration after all of the 4 S parameters are gathered. I need to wait for an extra two ports sweep.
Hope for your reply.
