I 'm using W/R visa using Ethrnet cable to communicate with MS8911B instrument. I tried many commands from programming manuel and it works good except one commande. So when I run with this one command I toke from programming manuel I receive error out code -073807339. I tried many commands using a BASIC I/O from MAX, all commands work except the one command. So why I still have this error.
When the instrument receives this commands, what does it, or is it supposed to do?
Do you have to send any other commands along with this command?
I know exactly what you are going through. By simply writing an ack response after my command I was able to get it to work. Try contacting the manufacturer of your instrument to see if there is anything missing from the manual they gave you. Sometimes they leave things out which are obvious to them.
This obviously differs from the other commands seeing how it is a query command, not a control command. Query commands state that each method should either perform an action, or return data to the caller, but never both. With your timeout error I can only assume that you are returning data to the caller, but have no way of doing it at this point.
Has this command ever worked for you? If so, what response did you get. The " *** " or "Parameter Error".
Your parameters should be automatically set to collect all the data present. In your previous commands do you have any way of setting parameters of sort. If so, I'd reccomend inputting the values for your parameters before you send :FETCh:MER?: as an extra fail-safe so you can complete all of your commands.
Does the "h" in that command represent anything in terms of parameters?
The manual says you have to specify the parameters TOTAL or ALL. The queries above do not have parameter information so that is why they work. Try FETC:MER? ALL.
