Device-dependent conditions, such as the presence of available data or an error condition, determine this value. In the classroom, an instructor is in charge of the class and controls activity. Back to Top 2. Not sure which one you downloaded. Message 2 of When you conduct a serial poll, the Controller queries each device, searching for the one that asserted the SRQ line.

Device-dependent conditions, such as the presence of available data or an error condition, determine this value.
Getting data from the Impedance Analyzer a – Discussion Forums – National Instruments
Message 8 of I’m not familiar with that instrument, but I took a quick look at the instrument driver for you. I pulled down the project-style one found here.
By the way, may I know the main difference between the Plug and Play project-style instrument driver as compare to the Plug and Play instrument driver? Is 10 seconds normal? The driver page says it supports Ethernet so if you have a problem, describe what it labvirw. I was able to get the data, there seems to be some performance issues.
Each device responds to the poll by returning the value of the Status Byte contained in its Status Byte Register see Figure 1. It’s usually better, though, to provide a front panel path control.
can’t run VI’s for 4294A
Whenever I try to collect a set of data, it would take over 10 secs. Hex 0x3FFF issue and the error code of If you have high-speed requirements you may need to look at alternative ways of getting the data, such as using a DAQ board.
I am sorry, maybe I am not being clear enough. As i 42994a the timing of each sub vi. Serial polling is needed so the Controller can find out which device requested attention. In the classroom, an instructor is in charge of the class and controls activity. Once the student raises his or her hand, the professor will ask the student for the answer.
Agilent Analyzer – Ethernet, IEEE (GPIB) Driver for LabVIEW – National Instruments
The “regular” drivers are typically packaged as a library. Was that an actual error? The connection worked just fine. The other bits in the Status Byte are left 494a the instrument manufacturer to define.
One function of a GPIB Controller is to detect and respond to service requests from devices on the bus.
Serial Polling and SRQ Servicing with NI-488.2 Software and LabVIEW
Message 4 of Because these bit definitions are not consistent among instrument vendors, the method for determining the cause of a service request varies with each device. As for your speed issue: Not sure which one you downloaded. Getting data from the Impedance Analyzer a.
The project-style drivers have individual VIs in separate directories organized like a project, and using a project file. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.
Message 3 of For that VI if you leave the path input unwired you will get a dialog asking you where to save the file. Any help would be appreciated. In addition, this application note also includes code examples that demonstrate how to implement the NI Message 1 of Depending on when they were written there will be differences in implementation and examples.
