How to control 8 current sources in the same time with labview?

Hi,
I'm a French student who have to create a program which is able to control 8 current sources in the same time.the aim is to plug the currents sources in the input of a laser.
If someone has an idea, it would be very nice to inform me !!!
Thanks in advance.

Is it really Tektronik or is it Tektronix. Tektronix is a major test equipment manufacturer. I can't find any reference to that model number on their site, though.
There are several resources for learning instrument control. One good place to start is http://zone.ni.com/devzone/cda/tut/p/id/4357.
Assuming that you have a NI GPIB controller for the pc, you will be using the Instrument I/O Assistant or the VISA commands to send/recieve data from the current sources. Without having access to the programming manual, I can't give specifics on what commands you need to send. Your topic mentions controlling them at the same time. Truly simultaneous control is possible in only a few situations. If you have a couple current sources in the same mainframe, you may be able to send a single command to set them all. It will really depend on the commands that the vendor has implemented. With separate mainframes, you will send commands first to one, and then another, etc. Again, depending on what the vendor has implemented, it may be possible to sequentially program all sources to a ready state and then trigger all simultaneously.

Is it possible to get 2-ch signals from TDS2012 oscilloscope at the same time with LabVIEW "7.0"?

Hi, everyone.
I've been trying to get the signals from 2-ch of Tektronix TDS2012 oscilloscope at the same time using IVI connection with LabVIEW "7.0"
I've already searched this developer zone for the answer.
I've tried the famous example: "IviScope - Acq Dual Wfm Edge Triggered.vi"
and it gave me the error message like:
Error -1074110451 occurred at IviScope Initialize With Options.vi
Possible reason(s):
Driver Status: (Hex 0xBFFA600D) Primary Error: (Hex 0xBFFA600D) The Config Server module is not present on the system.
I think I've installed all~ the required softwares for IVI. For example, ICP 2.2, IVI engine 2.0.46, and tktds1k2k ivi (instrument driver for tds2012, in fact this one is for LabVIEW "7.1"... :-P)
TDS2012 and my computer is connected through HPIB(GPIB) and it is shown on the MAX (a GPIB instrument as well as an IVI hardware asset)
I've tried GPIB connection but it gives me asynchronous signals...
Is it possible to get 2 signals at the same time with LabVIEW 7.0(not 7.1 or higher) by any means?
What in the earth is the "Config Server" in this case?
I don't need to sticking to IVI and any method to achieve my goal will be welcome.
Could anyone give me the hint for this problem, plz?

I think your problem is that the instrument specific driver is version 7.1 and you are using the class driver with 7.0. You can create your own 7.0 driver by downloading the LabWindows driver and using the Import CVI Instrument Driver under the Tools>Instrumentation menu.
Since you don't seem to have a good reason to use IVI, why don't you try the native LabVIEW driver at http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9139659CE034080020E748.... I believe you have all of the functions to setup each channel and then when you trigger the scope, both channels will be captured. You would then transfer each waveform separately. The data is always read sequentially but that's not important as long as both channels are triggered at the same time.

Can I view the same pdf on multiple iPads at the same time with 1 iPad operating as the master (controlling page turns etc)?

Would like to use 4nr iPads as an autocue system. Can I view the same pdf on multiple iPads at the same time with 1 iPad operating as the master (controlling page turns etc) and the others operating as slaves? Can this be done without the use of 3G or a remote Wifi hub? I would appreciate your input.................

Open the document in Acrobat Reader and use the menu Window > New Window.

Using Xmarks and Sync simultaneously will create a mess.
You can create a new profile, import the bookmarks from your main profile, and set up Sync for the new profile.
The flip side is, bookmarks from your main profile would not get synced with your new profile.
Alternatively, Xmarks is also available for Android.

[Bug] Writing to the same trace in Citadel from two Sources at the same time

Howdy
I am experiencing an issue and am looking to get some NI support:
I have two distributed applications that can write to a Citadel database at the same time.
And I am investigating the possibility of what would occur if both of them were writing to the same variable at the same time, with possibly the same timestamp data.
I did this in the attached VI by using the same timestamps with a constant for the data (either #1 or #2).
This generates an error, as expected, stating you cannot have two references open at the same time.
The data file, dumped from Citadel, contains 1000pts with all data from only one of the arrays (in this case #2) and everything looks fine:
However, what appears to be happening randomly tho, is that the same portion of code can also returns no error.
When the data is dumped from Citadel this file contains 2001pts - 1000pts from each array and one separator (or break) point:
You cannot write an older timestamp to Citadel without it throwing an error, but from further testing it seems you can write the same timestamp repeatably. So I am guessing what is happening above is race condition that is somehow allowing two references to be opened to Citadel which should throw an error but it does not and this is somehow allowing both sets of data to be written by both loops??
The data, IMO, is now corrupted.
Is being able to write to the same timestamp a desirable feature?
Or is this a known issue or a bug?
What about acquiring two references - bug?
Is there a workaround to protect the data from multiple distributed-application writes?
Cheers

The race condition of opening the refererence in two places at once should still apply to two different VIs running at the sametime.
Will a CAR be lodged for this?

If you open up the code and save it as a .vit, you don't get any missing VIs. Only when you change the extension without the aid of LabVIEW.
No VI should have missing members by simply renaming its extension outside of LabVIEW???
I think there is an issue with the VI.
Can you replicate the following and verify what I am seeing?
Attached is a Project with Main VI (contains a call to the Open Trace.vi polymorphic only), a Class and a Build Spec
If you Build the spec with the Main VI outside of the Class it works
If you place the VI in the Class, save then Build, the Spec fails with the error:

Save the VI
Close the VI

When our iPad is in use on the internet, my iMac internet connection goes off. I can't get the two devices to work at the same time with the AirPort Express. Is there a setting somewhere I may have missed?

When our iPad is in use on the internet, my iMac internet connection goes off. I can't get the two devices to work at the same time with the AirPort Express. Is there a setting somewhere I may have missed?

When two or more devices conflict it typically means that the DHCP service is either misconfigured or is not running at all. DHCP provides IP addresses to local network clients.
Is your AirPort Express base station the only router in your current network configuration? That is, is it connected directly to an Internet modem and not to another router upstream of it?

16 channels of audio recording at the same time with a MAC BOOK?

Hi,
I want to know how many channels of audio I can record at the same-time with a MAC BOOK (2.16GHz Intel Core 2 Duo, 1GB memory 120GB hard drive, Double-layer SuperDrive), firewire audio device and Logic Pro 8?
You see I am aiming to record a live gig and I want to come into a firewire recording interface with 16 channels of audio all at the same time (24-bit, 44Khz) Does anyone know if this is possible? Or am I looking for trouble? No plug-ins will be used just record straight in. Anyone have some experience with this?
Thanks.

Ok, like this:
Macbook - FW Port - FW Cable -In- MOTU Traveler -Out- External Harddrive.
Firewire is capable of chaining units.
Also plugged into your motu traveler will be an optical cable coming from the ADA.
This will carry the 8 channels of audio it outputs.
Also another good thing to do is to also have an optical cable FROM the optical output of your Traveler into the Behringer's input.
That way you can sync the Behringer's digital clock to that of the Traveler, giving you a slightly better sounding signal that if you were to sync the traveler to the Behringer. This is simply because the traveler has a better quality digital clock than the Behringer unit so it's best to use that. To do this you just select "Adat input" on the back of the Behringer, and leave the Travelers sync to "Internal Clock". It is only a very very slight difference and you may not be able to notice the difference but for the cost of an optical cable it's worth doing.
It will all make a lot more sense when you have the two units and the harddrive all plugged in.

Acquire Analog and Digital inputs at the same time with 6025E card

I have 6025E DAQ card, all the analog channels are used
up. There are several digital signals, such as flowmeter. Can I acquire both kinds of data at the same time with my 6025E card? Thanks for your help.

I suggest you search the examples that ship with LV
Digital
Find Examples>>>Hardware Input and Output>>>Digital Input and Output>>>8255
for doing each type of I/O seperately.
When you have found two examples. Just try to run the two at the rate use need in your final app.
Post follow-ups Q's here. I am not personally familiar with that deveice so I can not speak from experience.
I would generally expect that if you sample rate is low (i.e. <10Hz) you maybe happy with the results. If you want to run faster or have the PC do something else at the same time, the timing of the signals form the DIO lines may be suspect.
So...
It depends.

Can you use 2 bluetooth headphones at the same time with ipad?

I'd like to purchase 2 bluetooth headsets for my elderly parents to use with their ipad for FaceTime. They both typically use FaceTime at the same time to talk to their grandkids, but have difficulty hearing just using the ipad speaker. Is it possible to utilize 2 bluetooth headsets at the same time with ipad. If not, what's the best alternative? (Wired headsets will not work as they also are often caring for another young grandchild at the time and can't be tethered)

You can only pair to one BT headset at a time.
As an alternative, have you considered a BT speaker so you can increase the volume of the Facetime call?

Can you use 2 sets of bluetooth headphones at the same time with the Ipad 4?

Yes they just copy to the next page, the fields are the same. The document is an observation to school lessons so it needs to be consistent but with different data on.

How can i record 2 sources at the same time ?

Hello. I am a piano tutorial guy on youtube and am always trying to improve on the quality of my vids and so i go tan HD cam to record the videos in HD (canon HV30) . I also have this little app called "midikeys" and all it does is show a piano layout on the screen and the keys i press on my keyboard , light up on the on-screen keyboard. I want to know how to record my camera and that "midikeys" onscreen piano at the same time . i have a make shift workaround to doing this but it makes things a whole lot more complicated . i basically record the cam by imp[orting the live feed, and at teh same time a have quicklime recording the "midikeys" on the screen . is there a way to do it together ? thanks

Welcome Pianohero to the  iMovie boards..
.. is there a way to do it together ?
I dare to say: no way..
the hurdle to go is that 'keys visualizer' ..
as far as I understand, it does show 'live'.. and doesn't create quicktime movies, right?
so, you would need a 'screengrabber' tool as SnapZ or - better, but $$ - Screenflow.
such a screengrabber would create 'video files' of the action taking place on your monitor.
in a second step, you have to convert these files into something usefull in iMovie.
third step, you need an editing software which allows 'picture in picture' (=two video tracks). this an option in iMHD6 plus a plugin from geethree.com, or in iM09 or in FinalCutExpress ..
if anyone has a less complicated workflow..
