dynamic time delay between wright and read.

[Rasmus.Olesen]

Hi All

I'm woring on expanding my instrument sriver for my Agilent DSO-X4043A Oscilloscope.

I have made a VI that sets up a VPP measument and it works fine. Until I set the aqusition type to "Average" and ask it to do this over 128 measurements.

I suspect that this is due to the fact that it takes to long to do this averaging. So that I try to read before the data is ready.

Since I'm running this over ethernet, I dont have the otion of monitoring the amount of data ready to be read.

My question is therefore: Is there a way to determin when the scope is ready to "unload" the data?

I know I could set up a time delay, but I'm duing quite a lot of measurements. So I would like to have this VI running as fast as posible.

Help is much areciated

Have you tried an OPC? query? That stands for Operation Complete.

Hi Dennis

Yes, I just tried that without luck. 😞

I get the -1073807339 timeout error after my read command and when I check the scopes error log afterwards I get a "Instrument reports:
-221,"Settings conflict"" massage.

I can however not anything in the instrument manual about conflicts with the aqusition type...

What does the manual say about the status byte? Perhaps you can read that.
