PNA-X - CW Time - what the true resolution?

I am trying to measure switching time using PNA-X N85242A. I set the network to CW time sweep and the IF BW to 5MHz (maximum). Base on that setting I should have minimum resolution around 200ns. When set 11 point and move the marker from first point (0 time) to next point I am getting 1.46ns where the total time sweep showing 1.46us (1000 time wider).
If I increase the number of point to 1001 the  and move the marker from first point (0 time) to next point I am getting 133ns where the total time sweep showing 133us  (1000 time wider).
Non of the number correspond to resolution base on the set IFBW. How come?
What is the true resolution?

Can somebody implement Trigger level with defined threshold amplitude (in dB)  similar what you have in MXA Spectrum Analyzer?
