Communication trough Agilent 82357B

[Dejmek]

Hello.

There is lot of similar problems with GPIB/VISA communication, but I have a little bit different problem with compatibility.

Let me introduce that problem a and I hope so, somebody helps me with solution.

I'm using LabView v8.5.1, as GPIB interface is Agilent 82357B (with Agilent LS v 15.01).

Communication based on 82357B in LabView work perfectly trough VISA, If I connect an Agilent device (e.g. 33220A).

But, I have unsolvable problem, because I need to connect special HF supersound amplifier PARAMETRICS PR5800

This device contains GPIB board from NI, but it is not able to use VISA commands (even *IDN? doesn't answer) and do not sesponse on low level SCPI commands (e.g. ibfind gpib0 -> ibsic) though NI-488.2

So, my question is.. How to connect it together?

LabView <-> GPIB 82357B <-> PR5800

First, *IDN? is not a VISA command. It is an instrument command defined by IEEE-488.2. You send it with a VISA function. Second, ibfind is not a SCPI command. It is a low command for a NI GPIB controller and will obviously not work since you do not have an NI GPIB controller. Third, your statement that the device contains an NI GPIB board. Instruments do not contain 'boards'. They may or may not have a NI chip inside that performs the GPIB talker/listener functions. If you really do have a board, then this device may be designed to act as a system controller. The *IDN? query will not work and if it is a controller, with the Agilent controller also configured as a CIC (Controller in Charge), you are going to have some problems since you can only have a single CIC.

I did a google of 'PARAMETRICS PR5800' and could not find anything. Do you have a link or better yet, an electronic copy of the programming manual that you can attach?

I am trying to build the interface between 82357B and Labview to capture data from SR720 LCR meter. I am not finding any driver for agilent 82357B in Instrument driver of Labview. I am using Labveiw 8.6.1.

Please guide me, how can i make interface between them. If you have any sample program, that will be great.

Thanks. Kindly reply.

Did the PR5800 come with any documentation?  That is where you will find what commands are supported for your meter.  Your drivers for the PC and LabVIEW to communicate with your GPIB card obviously are installed correctly.  The 82357B is not the problem...  You need to get the info from Parametrics Inc. on their device.  You are likely going to have to build your own LabVIEW "Driver" to set it up and get what you need from it.  If their documentation is any good, it will have some examples, at a minimum, in some line language, but you should be able to interpret what you need from that.

The 82357 is not an instrument - it is a GPIB controller and it is made by Agilent - not NI. If you have lost the windows driver for the controller you have to contact Agilent. There have bee numerous posts on getting the Agilent controller recognized by MAX. If that is your problem, search the forum for '82357' or 'Agilent GPIB controller'

Dennis,

From his original posting, it seems that his Agilent USB to GPIB adapter is working fine.  For whatever reason, he expected there would be a driver for his  PR5800.  He can't "talk" to it using some of the standard SCPI commands and as you noted, he can not use the low level NI VISA stuff cause he does not have an NI card.  

He will need to go back to the manufacturer of his amplifier and discuss with them what commands are supported and how to interface with his instrument.

As an aside, I worked for a company that builds a receiver test set, and we did in fact use an NI GPIB card in our instrument (granted that inside the test set, there is a SBC with several cards in it.)  So this company Parametric INC, may very well be doing something similiar.   Granted that would still be an NI chip set... but that little sidebar has nothing to do with what Parametric INC chose to implement by way of commands to be supported.

Bhandi is not the original poster. Bhandi hijacked the thread. Bhandi is not using a PR5800.

My apologies then... Obviously, I do not pay close enough attention!
