Dear All

i use Agilent VEE 6.2, VNA 8510C and the Agilent 82357A USB/GPIB inteface for windows.
My problem is the time acquisition of the data.
I make a program where i acquire the S21 parameter with the VNA set in Continuos Wave and i put it in an  array (1 Dimension).
In particular i acquire the S21 parameter in a cycle (Until Break)  and to take it  very fast i acquire the marker displaying only the S21 parameter on VNA 8510C.
The time acquisition of the single marker is very slow for my application.   

Using a timer in the cycle the time to read the data is about 1,5 sec and it is not regular (it changes from 1,4 to 1,8 sec).

So what can i do to acquire the data in  a faster way?

Why the time is not regular?

Thank you in advance for your helpfulness
