I was testing SA44B on different platforms. It was mentioned before in other topic, that sweep time is dependend on cpu speed.
There was no difference on sweep time beetwen 3,3GHz and 2,7GHz proccesor, but there was difference on 1,47GHz proccesor. It was more than 2 times slower. Do you have information on what is the minimum speed, that the cpu wont affect sweep time?

That is correct, CPU speed affects sweep speed up to a point. That point is when the time to acquire data from the device is greater than the time to process it. For most sweeps, the processing can happen in parallel with the data acquisition. There are many factors at play here (single vs. multithreaded processors, RBW, VBW) and so it is impossible to give you a single number that would meet your needs. The sweep times you see on the 3.3/2.7 GHz processors are almost certainly the fastest those sweeps can perform.
