Problem of data acquisition using 'write to measurement file' vi

[사과나무]

Hello

I'm using Keysight VNA E5071C and obtaining data via Labview.

I'm struggling for data acquisition when the number of data points is more than 400.

When I input data points of more than 400(such as 1600), the data in the text file obtained from "write to measurement file" vi shows some errors that some data points are zero. 

The data shown in Labview is fine but only the data saved in the text file shows the error above.

Would you please let me know about how to solve this problem?

Here, I attached my VI named E5071C with sub_vi.

Thank you

The change anyone reading this can run that VI is tiny. (Having a Keysight VNA E5071C && reading the forum && time available && knowning the answer == false)

Isolate the problem. Try to do just the file saving (with simulated or random data). Post that if it has the problem. You might actually find the problem while doing this.

I tried it and found out there is no problem on saving file.
