Hi Xiangdong,
We looked at the time it took for each NMR cycle for fixed Tdown and Tup times (Tdown=Tup). We also looked at the number of stored points for each cycle and graphed the points per second. Both graphs are attached. The dip in the timing which occurs after Tdown=Tup=30 seconds indicates a change in the lock-in amplifier's data acquisition rate.
The time for Tdown=Tup=25 seconds is 133 seconds with 13,324 data points. The time for Tdown=Tup=30 seconds is 157 seconds with 15,857 data points. Could the cycles be run at Tdown=Tup=25 seconds to make up for the timing difference between Windows 10 and Windows 7? Dropping acquisition speed at Tdown=Tup=30 seconds to give a faster cycle time would give far less data points than running the cycle at Tdown=Tup=25 seconds (~8,000 data points).
Regards,
Amanda
