Message 5 of Whenever I try to collect a set of data, it would take over 10 secs. The question can be interpreted in the classroom analogy as, how can a student let the instructor know that he or she has something to say, considering that the student cannot talk to the instructor unless the instructor says so? If you have high-speed requirements you may need to look at alternative ways of getting the data, such as using a DAQ board. It’s usually better, though, to provide a front panel path control. I have browsed through all the provided examples in the driver. A good method is for the student to raise his or her hand.

Agilent Analyzer – Ethernet, IEEE (GPIB) Driver for LabVIEW – National Instruments
Not sure which one you downloaded. First of all, I must admit that this is my very first time using Labview. Getting data from the Impedance Analyzer a.
I am using Labview 8. This is a completely separate line in the GPIB bus dedicated to letting the Controller know that a device needs attention. Message 10 of But this is not possible in every case. The driver page says it supports Ethernet so if you have a problem, describe what it is.
For that VI if you leave the path input unwired you will get a dialog asking you where to save the file. As far as what those difference are, you can’t really say, as it depends on the drivers and when they were written, as well as labvie whom.
Instrument Control (GPIB, Serial, VISA, IVI)
Most Active Software Boards: I woulnd’t count on getting data that fast, especially if you’re using serial. I tracked it down to the “Read Data unknown length” inside the “Read Data and memory array. But, how can a device let the controller know that it has something to communicate if it cannot start talking to the Controller without the Controller telling it to do so?
The other bits in the Status Byte are left to the instrument manufacturer to define.
Lahview device responds to the poll by returning the value of the Status Byte contained in its Status Byte Register see Figure 1. The project-style drivers have individual VIs in separate directories organized like a project, and using a project file.
In addition, this application note also includes code examples that demonstrate how 429a4 implement the NI The most common method for SRQ detection and servicing is the serial poll. Back to Top 2. Is 10 seconds normal?
In the classroom, an instructor is in charge of the class and controls activity. Any help would be appreciated. Rate this document Select a Rating 1 – Poor 2 3 4 5 – Excellent. As for your speed issue: The connection worked just fine. When you conduct a serial poll, the Controller queries each device, searching for the one that asserted the SRQ line.
Was the “status” boolean in the error cluster actually on? Message 9 of But I just have no idea how to do even that.

Message 8 of As i track the timing of each sub vi. In some cases, a Controller can request data from a device writing to the device and read the data back as soon as the write operation is completed.
Message 7 of A good method is for the student to raise his or her hand.
