Hi Folks,
i am a small technican and i have made additions to the web control website for our E4440 Analyzer.
The Addition s a drop down field where i can select and load states form the e4440.
For This i am using php. See Code below:
My problem s that everytime i want to load a state or do something else with this script the instrument sometimes does it or not.
I can't figure out why it does it or why it doesn't do it.
But everytime i do a command i get this Error on the serverwindow:
Has this something to do with the problem that it sometimes does it and sometimes not?
I hope that you can help me with this. Perhaps somewone knows a better way how to send commands via a website to the instrument.
Thanks in advance !!!!!

The bad IEEE 488.2 binary block header is most likely caused by the instrument not returning data before the new state is loaded. The Web Remote software is continually grabbing trace data using the binblock format. If a load state command is sent right when the software is also requesting data, this can cause a problem like this. To avoid an issue, you could go to single sweep to pause the measurement first. Also, the Web Remote software wasn’t designed to be running at the same time that the instrument is also being remotely controlled by other means.
