34410A DMM stays in Remote mode after session, using USB

My Agilent 34410A DMM stays in remote mode after my code exits, or if I use MAX to communicate with it, but only if I'm communicating over USB. If I use GPIB, the DMM returns to local mode when my code closes. Apparently there is no LOCAL command for this instrument. Is there any way, other than pressing the Local button, to put the instrument back in local mode using a USB interface? I call hp34401a_close() to close the instrument.
Thanks for any suggestions.

Hi JoeN,
I think what is happening is that when using the GPIB interface you are sending a code to set the instrument back to Local. I took a look at the user's manual for the hp34401a and it seems to have a command to set this back: SYSTem:LOCal.
You can try this at the end of your USB interface program, and see if this is able to help you out. Otherwise I would run NI-SPY on the GPIB end and see exactly what command is being sent to disable remote control of the device.
Let me know if this helps

ViScanf invalid format string due to #sample size data1, data2,... response

I'm writing a program which will utilize the internal memeory of the Agilent 34410A DMM for making fast measurements (10K/s). In order to do this, I need to setup a test, have the data stored to the internal memory, then read and delete it, while other measurements are still happening. The best command for the read/delete function is the R? command, but it returns the data in a strange format which breaks the ViScanf format string.
an example of the R? reading in below:
R? 2
#231+2.87536000E-04,+3.18131400E-03
Is there a way to setup the ViScanf format string to handle this?
Thanks
Ryan

Yes, I am using CVI
If it was just returning one value I would use a simple viScanf function like this:
viScanf (vi, "%f", fbuf);
If you do a READ from in the instrument, it returns an array of floats so you need to adjust you viScan fuction parse the string into an array of floats like this (array of 500 for this example):
viScanf(vi, "%,500f", fbuf);
The problem is the data response to the R? command starts with the array size and is then followed by the data (#231+2.87536000E-04,+3.18131400E-03). In the previous example, I need to delete the #, and parse the 231 into an array size variable and then fill an array (fbuf in this case) with the data.

Ivi step 34410

I have been using the ivi step for a DMM step in Teststand. When using a NI dmm to read a voltage the ivi steps works ok, but when using a Agilent 34410A DMM it does not give the correct reading back. I have downloaded the 34410a driver from NI and used this rather than the one from Agilent.
Is it the case that the NI_ivi_DMM step only works for a NI dmm and not any other manufacturer?

No, the ivi step should work for any instrument with an ivi driver. How different are the readings? Is the configuration correct? You should be able to set a breakpoint before the read and check the setup on the 34410 front panel.

Labview et instruments de mesure Agilent

Salut !
Je travaille sous LabVIEW 8 et je pilote des instruments de mesures Agilent (DMM 34410A, générateur 33220A, oscillo DSO6012A et spectrum N1996A) connectés via LAN.
Y a-t-il des membres du forum qui travaillent avec ces équipements (ou proches) sous Labview ? Peut-être pourrions-nous échanger des actuces...

bonjour,
Je commande un GBF Agilent 33220A à l'aide de LabView et j'ai aussi des problèmes avec le close. Le VI "close" s'execute mais le GBF reste sous le control de Labview (impossible de reprendre le mode manuel sans appuyer sur le bouton "local").
De plus, lorsque j'arrete mon programme, le GBF stock la derniere valeur (surement dans un buffer) et me la renvoie à chaque relancement du programme. N'y a t il pas un moyen de supprimer la memoire du gbf pour qu'il m'envoie la valeur de fréquence que je lui envoie avec labview lors de l'initialisation de l'instrument??
Pourriez vous m'aider ??
Merci d'avance

Communication problem with agilent 34401a

Hi all,
I' m using Labview 8.2 and visa 4.2.
I 've connected my agilent 34401a and it is recognized, I see it in agilent connection expert and manage to communicate with it. (query *IDN?)
But I get a problem when I want to use the control_mode vi. (remote or local).
the error is displayed just after the Visa Read function (Vi below)
I don't understand why. I use the RS 232 connection and it is correctly configured in the devices manager.
Anyone can help me ?
Thanks,
Romain

Sorry,
I've forgotten the Vi.
Now it's OK
Thanks

Rack mount kits doesn't fit the depth of Agilent rack

I have a PXI 1085 Chassis which I want to mount in an Agilent rack. I purchased the front and rear rack mount kits, the height and width are great, but the depth of my rack doesn’t allow me to use both the front and rear rack mount kits. Is there some kind of adapter I can buy which will extend the rear rack mount so that it can reach the back?

Hi Chall,
Unfortuantely we only offer the kits for a certain size range. If this does not fit your rack then you will have to create a custom rack mount.

When trying to work with Agilent 34401A multimeter (serial RS-232 connection), HP34401A Getting Started.vi gives always the message: "Error 1073807369 occurred at Old VISA Open ".

Baud rate and parity are set correctly, RS-232 cable is also connected correctly. My QuickBasic program has no problems to read and write to the Multimeter. It is obviously a software problem: the same error is persistent if I disconnect RS-232 cable.
I downloaded NI-VISA 2.6 for Windows 95/98/NT/ME/2000/XP frorm digital.ni.com and installed it. But it did not help.
Thank you in advance

How to resolve the error -1073807339 when using Agilent LAN/GPIB Gateway (E5810A)?

Dear Sir/Madam,
Appreciate that you could advise me on the following error occur when connect power meter E4419B to computer via E5810A LAN/GPIB Gateway(remote interface) & run with Labview:
-1073807339
VISA Write in E4419_read_power.vi
I have added 5s timeout to Labview program but the result as previous.
There no error occurs when the power meter to computer via USB/GPIB interface(82357B).
Is it related to E5810A driver or the program I wrote?
How to resolve it?

Hi.
I'm experiencing the same problem when connecting a laser controller (New Focus Vortex TLB-6000) via the Agilent E5810A to a PC.
There are no problems when connected through a regular serial port, but timeouts arise every few seconds through the E5810A. I have another controller (SRS LDC501) which works very well with a second Agilent console.
Have you managed to find a solution to this problem?
Thanks,
Orel.

How do I use LabVIEW to control and vary the voltage on my Agilent Power Supply and simultaneously record temp from 1 DMM and voltage from another DMM?

I am using an Agilent Power Supply to apply a voltage to a
thermistor to heat an Al chassis. I want to use LabVIEW to tell
the power supply to apply 5V for 10 minutes, then step to 7V for 10
minutes, etc. I am completely new to LabVIEW, so any help would be greatly appreciated!
In addition to that, I want to place a type J thermocouple onto the Al
surface and use a Keithley 2000 DMM to monitor the temperature (it has
a built in conversion from V to Temp for type J). I will also be
using another Kelthley 2000 DMM to record the output voltage of a new
uncalibrated thermocouple. I would like to collect the output
voltage for this uncalibrated thermocouple and the temperature reading
from the type J simultaneously. How should I go about doing this
in LabVIEW? I will be using version 6.1. The power supply
and DMMs will be connected to a PC using GPIB.
Again any suggestions would be greatly appreciated- I have no idea
where to begin on such a project. I have taught myself how to
make a basic VI- converting temp in oC to oF, but that is as far
as my knowledge goes.

What you want to do should be fairly straightward and a good way to learn labview.
First off, if you haven't already, I would download the drivers for the Keithley and Agilent instruments. I found the keithley drivers at the link below. You will need to find the labview drivers for the Agilent PS at their website. Drivers are the VI's you will use in your program to control the insturments.

If you open Labview and go to the help menu and click on Labview bookshelf there is alot of information on getting you started coding labview. This should get you started, if you have anymore questions just ask in this same thread and I am sure you will get all the help you need.

Connecting hp 8508a vector voltmeter with agilent 82357a usb/gpib converter

Hello
For my experiment, I need to connect to a HP 8508A vector voltmeter by using an agilent 82357A usb/gpib converter. I have a serious problem about communicating with my device using NI-VISA. I tried to do the steps indicated at following links which were indicated at the forum posts by people using 82357A:
http://digital.ni.com/public.nsf/allkb/F7C187DBF09EBE1186256F550065BD32?OpenDocument,
http://digital.ni.com/public.nsf/websearch/3B3626D9C1F999218625694200791AD7?OpenDocument,
http://cp.literature.agilent.com/litweb/pdf/5990-3731EN.pdf?cmpid=1273CN.
The version of MAX is 4.3.0f0 and i am using labview 8.5 with NI-VISA 8.2. I am trying to configure my 82357A using agilent io libraries suite 14.1.
First, I tried to configure my usb/gpib controller using agilent connection expert and set the visa interface id to GPIB6 and connect to the 82357A without any problems. Then I connect this gpib converter to my vector voltmeter. The gpib adress of the voltmeter was 6(gpib address of the interface converter was 10) so visa address GPIB6::6::INSTR was assigned to voltmeter by connection expert. I tried to connect to the voltmeter from the connection expert by using the agilent interactive IO. Send *IDN? command and took the proper response from the voltmeter. The voltmeter went into remote mode and I tried to read the voltage values by using the FETCH? command of the device and got the voltage properly which means I successfully connected to the device.Then I went to MAX and enabled the NIVISATulip.dll and restarted the MAX. Then I went back to agilent connection expert and checked the box: "use agilent 488 library where possible" for side-by-side communication between the NI and agilent visa. By the way agilent visa was installed as the secondary library. Then when I went back to MAX, I start to see the voltmeter under miscellaneous VISA resources with the address GPIB6::6::INSTR. But the problem started here. When I tried to send commands from MAX to voltmeter with the "open visa test panel" I encountered an error which exactly says:"unable to open session to GPIB6::6::INSTR, return status code:0xBFFF009E, status name:VI_ERROR_LIBRARY_NFOUND, a code library required by VISA couldn't be located or loaded." As I said before i enabled the libraries of agilent 488 from the options of the agilent connection expert. When I went back to connection expert and unchecked the box for using agilent 488 libraries nothing changed. Also when I went to NI-VISA interactive control I couldn't see my device under the tab of VISA I/O.
I tried to read some posts from this forum. People are using this usb/gpib converter successfully without any problems by performing the steps I have done. I have some questions about possible subtle points specific to my application.
First question is according to the manual of the voltmeter(this is an old device by the way from 1988):"vector voltmeter is capable of remote operation via the HP-IB which is HP's implementation of IEEE standard 488.1 "So, what I understand from this sentence is my device is communicating remotely with IEEE standard 488.1 and not 488.2 Does it make any problem? What kind of modifications should I do to my setup for overcoming this if it creates any problems? As I said before I was communicating with device very properly from the agilent connection expert. In manual there is also a sentence like "HP-IB commands used in the vector voltmeter conform to the standards set by document IEEE 488.2 1987."
Second question is should I install newer versions of agilent io libraries suite or MAX or NI-VISA. I wrote the versions I am using before are they compatible? Where can I install newer versions? As I know the newest version of the agilent io libraries suite is 15.1 or 2. Is is compatible with 82357a?(maybe I should ask this question to agilent people)
Third question I don't remember how I did it but agilent visa is indicated as secondary visa resource in agilent connection expert(I think I did it while installing agilent io libraries suite.) . How can I switch between NI and agilent visa as primary visa resource? Do you think think this will help?
I terribly need measurements from this set up and really appreciate your help if possible.
Sincerely
Caglar Yavuz, University of Michigan,Ann Arbor,EECS department.

Caglar,
The documents you mention ahould include the proper prcedure for using this hardware in LabVIEW. Here are my recommendations:
The version of NI-VISA you mentioned is not valid. The most recent version is 4.6.2. I would recommend ugrading if you do not have this version. After the upgrade,ensure that tulip is enabled as well as the other settings and see if this helps.
When talking about the instrument, the biggest concern that usually is relevant with 488.1 is that it will not respond to *IDN?. In your case, it looks like it does, and should work as 488.2 is backwards compatible. It seems to me, the issue is still with the 82357A, and we have not yet reached the voltmeter.
In order for NI-VISA to work with your device, NI-VISA must be the primary visa driver.
Hope this helps, let us know how the upgrade turns out. If you continue to have issues, take some screenshots of the preferences in MAX and upload them on the forum.

Peter Flores

How to synchronize File Manager Server when I install Agile on distributed?

The Environment I install is : two Agile Server , two File manager Server ,one Web Proxy Server, one DB Server .
The Agile version I install is Agile 9.3.1 for Linux ,the Middleware is weblogic 10.3.2 .
Now I finish install two Agile Server ,and successful make two server compose a cluster.
Now I will install two File manager Server ,I want to ask what's the method let me synchronize two file manager Server ?
Does the File manager has this mechanism to let the file keep synchronize on two file manager server?
I find a PDF name "Agile PLM Capacity Planning Guid" V 9.3.1 ,it says there are two software can synchronize file manager server , is XXCOPY and RoboCopy, but the two softwares only support Windows . Is there a software support synchronize file manager server on Linux ?

Hi I believe you have the wrong forum.
This forum is for the Agile PLM for Process product suite, not for the Agile A9 suite. For Agile A9 or Primavera questions, you can use Oracle Support, Support Communities, Yahoo Groups for Agile API or WRAU.
This forum is for Agile PLM for Process, which is part of the same Agile family but a different product.
Thanks.

it doesn't do anything, stays at the same placeIt's all about context here and there are still many unknowns here that can effect your result and that you have not told us or shown us. My suggestion to you is to consider posting an SSCCE (Short, Self Contained, Correct (Compilable), Example, a condensed program similar to your current program in that it demonstrates the problem at hand, but is the smallest bit of code that still compiles and has no extra code that's not relevant to your problem.

Also, when posting your code, please use code tags so that your code will retain its formatting and be readable. To do this, you can will need to paste already formatted code into the forum, highlight this code, and then press the "code" button at the top of the forum Message editor prior to posting the message. You may want to click on the Preview tab to make sure that your code is formatted correctly. Another way is to place the tag [code] at the top of your block of code and the tag [/code] at the bottom, like so:

// note the differences between the tag at the top vs the bottom.
[/code]or
{code}
// your code block goes here.
// note here that the tags are the same.

How to Reset the Sata Link Controller for Full Sata 3 speeds on an OCZ Agility 3

So I purchased a new OCZ Agility 3 drive, installed it into the main bay of my 2012 Macbook Pro, and the drive was running at half speed. I called OCZ and spoke to the guys about how to resolve this issue, they were very knowledgeable, but they had no ideas how to make thier Linux Live Tool work on the Mac, which gives us the ability to reset the controller. Here's what I did to get the full speeds out of my OCZ Agility 3.
- You will need a Windows computer, or the ability to create and install Windows on a Bootcamp partition on your Mac.
- Thumb Drive
- Lots of Patience
1. Open Disk Utility and create one partition on your thumb drive under MS-DOS Fat 32. Click the Options tab and select “Master Boot Record.”
2. Go to the OCZ forum and download the older Linux Live Tool version: OCZ_Tools_316-old.zip. From my experience, the newer version doesn’t work on the 2012 Macbook Pro.
3.Download the “Universal USB Installer” for Windows, and follow the steps to install the ISO to your Thumb Drive using the instructions located on the OCZ Forum. http://www.ocztechnologyforum.com/forum/showthread.php?99275-NEW!-Bootable-Linux -based-tools-for-OCZ-SSD-s&p=714047&viewfull=1#post714047
4. Once the ISO is successfully copied to the Thumb Drive, insert the USB stick into your Mac with the OCZ SSD installed in the Main Bay, Power On, and hold down the “Option” key. You should see a yellow hard disk icon that says “Windows,” select it and press enter.
5. Once the OCZ Tool loads up, click the “Green Arrows” to put the drive into Sata II mode. Shutdown the computer, power on, and check the System Profiler. The drive should be running at Sata II speeds.
6. Shutdown the computer and boot into the OCZ Tool, and click on the “Red Arrows.” This will reset the controller to its default mode of Sata III (Sata 6 Mode).
7. Check the speed of the drive using the disk speed test of your choice. The drive should now be running at full speed.
The biggest accomplishment here was actually getting the OCZ Linux Live Tool to load on a 2012 Macbook Pro. The newer version of the tool doesnt support the USB 3.0 drivers, so you loose the funtion of your trackpad and keyboard or bluetooth keyboard and mouse.
**Note: Black Magic Disk Speed Test Version 2.0 may give you lower numbers than expected due to the compression method in testing the drive. I would prefer using XBench or Disk Speed Test Version 1.0**
***Here's a link to a thread that explains how to properly install your OS onto the drive. If not done correctly, this can also cripple the speed of the drive.***

I can almost see a big grin appearing in Bob's avatar...
Hopefully his reply has given you a clue already?
If not, some explanation:
Many settings in the standard "Media" panel (for both video and audio) don't apply for publications that need to go the Folio-way. This panel is mainly concerned with lovely Flash stuff, but apart from the Poster frame and the Markers, it is useless for Folio's.
A quick guide: create a video with the necessary codec (H.264 for video, MP# or AAC for audio) at the required pixel size (exact width/height). Simply Place the file in InDesign, but don't scale it (or recreate and place a properly sized new video afterwards). Choose what to do with the Poster frame (and maybe some Markers), but all other settings are done in the Overlay Creator.
Check Bob Bringhurst's Tutorials and his DPS Tips app for more info. But I guess you get the idea now.
