All that you have done is attach the example program that comes with LabVIEW. You haven't written anything as far as I can tell. No one has any idea what commands you are actually sending, what format you are sending them in, or what command you are supposed to be sending. Enter a command and then go to the Edit menu and select 'Make current values default'. Save the VI and then post that. Attach the manual as well. My guess...

I believe that I found my problem. I wasn't setting up a current for the power supply, and it defaulted to 0. Since I've changed it, I haven't encountered the problem.

You can install the latest LabVIEW version in another PC with XP os and install latest version of NI VISA and then control the oscilloscope with the drivers. I already did so with TDS7404. Let me know if i can help out. Mathan

Thank you Juergen! I made a screenshot on the FSL but got only the grid part. Thanks for the reference to the Commander Tool! Regarding the low attenuation problem, I'll wait until one solution from R&S. João

That makes no sense. If it's a USBTMC device, you do NOT use the VISA wizard to create a driver. The wizard should be used only when you have a USB device that does not have any sort of existing driver. It is really to be used as a last, desperate attempt to communicate. Discard all of the changes you have made. If there is a driver that comes with the device, install that and nothing ...

Hey, It seems like the device is drawing more current than the USB port can provide hence it is droping out. Can you try it on different port, or try it on another machine. Good luck lab

1. Read the manual for your 341 driver, especially the RS-232 section and programming commands. 2. Connect up the hardware, connect to the serial port and confugure and use Hyperterminal to send commands as a test. 3. Then in LabVIEW, search examples for Basic Serial read and Write.vi to send commands and read data back. -AK2DM

I don't have direct experience, but I use Lecroy scopes via ethernet connection. If you use TCP/IP drivers as well, I believe you just need to input the "local host" IP as address

Hi Hanna80, There are a number of ways you could solve this problem. You could certainly use a math script node, but I would suggest using the standard LabVIEW Mathematics functions like this: I simply implemented the equation to find the ith value of Y. The two inputs coming in from the left are Ra and Rb, and the input from the bottom is Zi. Once you have your equations implemented, you...

The current driver has no VI called 'Getting Started' so I'm not sure what you are using. Where exactly did you get the driver? What version of LabVIEW are you using? The project style driver has an example called 'Agilent 5460X Series Multi Channel Function Display.vi' and in order to acquire multiple channels, you have to configure them ('HP54601A-602B Channel Config.vi) after ...

Sorry can't open your vi... still on 8.6.1. If you have an array of values, you can feed them into the file vis. Seen the examples provided in Fundamentals - File Input and Output ? Don't know if you did, but there are ready made driver vi's for the 3458 here at the ni-site, browse the driver network.

The GPIB driver uses SCPI so you should be able to modify the driver for RS-232. The driver uses tow functions to read and write. Instead of the GPIB functions, you can replace them with the equivalent VISA functions. It's not really a very difficult task. More tedious than anything but you might want to spend some time learning LabVIEW basics and the structure of an instrument driver ...

What 'pressure program' are you talking about? The DB9 cable is connected to what? Can you attach the code that you are using?

This might be a question better asked of Agilent tech support. There are some things that you could try yourself. Experiment with variations of the command. Look up the syntax in the manual. Perhaps part of the entire command causes the instrument to briefly switch on/off. See if you can send just the frequency command.

There are multiple drivers for the instrument. Provide the actual one that you are using.

Scope settings are incorrect! The users manual will tell you how to set the scope's GPIB parameters.
