No appropriate tunable laser source found

[calvinkuek]

I m using Agilent 8163A.When i run my program,the message indicator which connected to error message.vi display "No Appropriate Tunable Laser Source Found". Can anyone tell me what is the problem?I already switch on the laser source, the device laser source status also show "ON".

Hello,

What interface are you using to connect to your 8163A? Who wrote this program? You may need to contact the software author or the hardware vendor, but if you can provide me with these details, perhaps I can help.

Good luck and let me know if I can do anything else for you.

I m using USB/GP-IB interface.I write the program myself.I program it similar with the lambda scan function for Agilent 8164A example that provide by Agilent. My TLS module is connect to the power sensor module.
I m using labview 6.1 in window XP.I ll attach my program at below and the driver also.

Hello,

Is your GPIB device able to find your instrument? Does it show up in Measurement and Automation explorer? It sounds like you're able to communicate with your instrument, but that your instrument is returning an error when you try to do something specific. I do not have experience with your instrument, unfortunately, and one is not available for me to test your program.

If you are having instrument command set problems, contact the instrument manufacturer. If you are having general connectivity problems and you cannot send or receive data from your device, then I can help you out. Let me know whether or not it is detected in Measurement and Automation explorer (MAX), and whether or not you can communicate with it in MAX directly.

It can be detected in MAX.I m using visa assistant to communicate with it.When i press idn/ , it does return back the module status.
I have contacted the Agilent measurement engineer,but they don't know about labview,so can't help me.They want me to use scpi command,which i don't know.

I can set TLS and power meter,but cannot retrieve the lambda scan result. Everything is ok with the first function, Initialize, then follow by the Set TLS Lambda and Set Power Meter. When it come to prepare lambda scan function, the error out message show that "there is no appropriate TLS source". I connect the prepare lambda scan.vi status to error message.vi to display the error message.
The truth is that TLS in ON already.
Thanks for helping me.

Regard,
calvin

Calvin,

SCPI commands are simply the text-based commands like "*IDN?" that return and set attributes on the device, query the device, etc. It sounds like you're already using SCPI commands to "Set TLS and power meter", though you may be doing this indirectly by calling some of the instrument driver functions.

Are you using one of our instrument drivers for this device? If so, are you using the Getting Started example for that instrument driver? Can you give me a link to the instrument driver that you're using if you are using one? I wasn't able to find the one that you posted on our site at www.ni.com/idnet, so that leads me to believe that it was written by someone else. The author of the instrument driver will probab
ly be able to help you use it.

Otherwise, you can use SCPI commands from LabVIEW using the standard GPIB Read and Write VI's or the VISA vi's. If you know what SCPI commands you need to send, take a look at the LabVIEW GPIB shipping example by clicking on "Help...Find examples" in LabVIEW and searching for GPIB. This will allow you to send and receive the text-based SCPI commands that Agilent can help you with.

Hope this helps.

hi,
I m using drivers from Agilent website.The driver is hp816x.This driver is for Agilent 8163A Lightwave Multimeter.
Thanks for your help.I already manage to control the TLS source,but my problem now is that i cannot retrieve the data from power sensor module.
The wavelength and power meter i get from 2 of the subvi is exactly like the wavelenght and power meter i set.
The truth is that the TLS lightwave multimeter display a different wavelenght and power ,due to insertion loss.
Do you have any idea of this problem? 😃
Thanks for your help ok

I'm sorry, the level at which you seem to be having a problem is the driver/instrument level. You seem to be successful in establishing basic communication via your GPIB board and LabVIEW. Since your driver and instrument were provided by Agilent, I do not know enough about them to be of use to you. I suggest contacting them for further support.

Thanks,

Hey I am facing a similar problem. The error message is  hp816x Prepare Lambda Scan.vi ERR Driver Status:  (Hex 0xBFFC0D02) Visa Resource not found. Check HPIB-Bus Address!  the hpinitialize.vi is recognizing the device and I am passing the ihandle from intialize to the prepare lambda function.

If anyone can help me that would be great
