Avant de se lancer dans un nouveau téléchargemetn de 2Go, vérifiez bien que votre version de LabVIEW est supportée - ce serait trop bête (NI-SCOPE 14.1 supporte LV 2011 SP1, 2012 SP1, 2013 et 2014), et qu'accessoirement, la carte que vous souhaitez utilisée est elle aussi dans la liste des matériels supportés. Pas de panique, dans le cas de NI-SCOPE, il n'y a que très peu de cartes non-supportés sous Windows Seven. Attention à la distinction 32/64-bits.

Urgent problem! please help. high speed digitizer, channel switch time too long!

Dear all NI high speed digitizer experts:
I post a question concerning the two-channel configuration using NI5154 digitizer (see Need help to configure a two-channel acquisition using NI5154 ).
As we need to do some measurement using NI5154 very soon so purchase a DAQ board as suggested by Efrain is not a option for our coming experiment. So I try to configure the NI5154 a two channel acquisition. I configure the NI5154 to count pulse in two channels. Our experimental setup will send pulse to channel 0 for 400 ms and then stop. 100 ms later pulses from other source will be send to channel 1 for 2 s. I thought the 100ms dead time in our setup would be long enough for the digitizer to switch from channel 0 to channel 1. But after some test I found the digitizer takes more time to switch between channels.
I made a test vi (NISCOPE-Timing.vi) just for count how many ms it takes for the digitizer to switch between channels. In the attached vi, if you run for only one channel one loop takes about 20 ms in my pc. If you run for two channels it takes about 130 ms for one loop. If you just run one channel twice the loop time is about 40 ms (I mean stop a channel and then restart the that channel).
I don't understand why it takes so long to switch from channel 0 to channel 1. As I tested the niScope Commit.vi consumes a lot of time for the second channel. Is there any way to avoid this? We can not extend the 100ms long dead time of out set up so I must get rid of this problem.
Solved!

Hi Lixin,
There are a couple of different options that you may try. The first, which it sounds like you may not prefer, is to use the TRIG line on the 5154 and somehow find a way to route both sets of pulses to that line. You can either somehow connect both lines to the one input or use some sort of external switch since the signals will not come in at the same time.
Unfortunately, what you re seeing in terms of the time it takes the board to reconfigure itself for a different trigger channel and re-inititiate is due to the settling time that is necessary for the board to be able to fully reach its specifications. The majority of settling usually occurs pretty quickly, but the board will wait for some time to get the best possible performance in terms of specs. If you are okay with reducing this settling time (and very slightly diminish the specified performance), then you can use an internal scope property to set the max settling time.
I have attached a .rc file which must be placed in the LabVIEW directory for niScope to enable use of this property node. Please place the file in your ...\Program Files\National Instruments\<LabVIEW 2009>\instr.lib\niScope directory. Once the file is in that directory, restart LabVIEW, and you should be able to see a new category in the niScope Property Node tree titled "Internal". Under that category, you will have the Max Settling Time property, which gives the driver a maximum amount of time (in seconds) to wait for settling before beginning a new acquisition. Add this new property to your first property node at the beginning of your program. I tested this out with a value of 50 ms and found that my initiate went from ~125 ms to ~53 ms or so after reconfiguring the trigger channel and re-initiating.
Hope this helps!

Multichannel stream to disk high speed digitizer problem

Hi,
I'm trying to write a code for managing a PXI-5105 high speed digitizer as a multichannel data streamer to disk.
I found the code example on niscope folder (version 3.0) for a single channel datastreaming that works fine. I tried to modify this code,
according to directions included into the code for multichannel acquisition, but it fails. I wrote to NI support and they confirm that my code has to work.
For clarifying better my question, I include my code.
I'm a quite new labview user, I know that my code is not easy to read, but I hope that someone has already encountered my problem and may help me.
Best regards
Paolo

niScope EX Stream to Disk_Paolo_version.vi ‏86 KB

Hi Matthieu,
thanks for your attention to my problem.
The program runs, but it dispays only the first acquisition (first loop), and after there are no data acquired.
Using the single channel mode it works fine, you see a continuous acquisition on display and on disk.
I'm suspecting that there is a problem in the loop where I acquire fresh data (Using the lamp I haven't any data from the Niscope I-16 multichannel block, except for the first run where I get the first data).
I hope this clarify better the situation.
Best regards
Paolo

I have an NI5911 high speed digitizer and would like to acquire a video signal from a CCD using it. Does anyone know if this is possible without buying any more hardware please? If it is, how would I go about it?

The only thing I succeeded in finding on the NI site was about using a different high-speed digitizer in tandem with an IMAQ card but I was hoping not to have to buy an IMAQ card as it means I may as well not have got the NI5911 (a while ago) in the first place. Any help would be greatly appreciated!

You can certainly acquire video signals with the 5911. The only tricky part is that the 5911 does not have any video triggering options. That means that you will have to either find a way to provide your own trigger based on the video signal (that's where the IMAQ board comes into play) or you can just take a lot of data and keep only the data you need once it is in software. For instance, you could take one large record and then use software analysis to determine where the frame sync occurs. Hopefully this was helpful.

Synchronisation of M Series and High Speed Digitizer

Hello everybody,
i just have a question regarding synchronisation/timing of two different PCI cards (M-Series PCI 6220 and High Speed Digitizer PCI 5112, connected via RTSI cable).
I wonder how I can synchronise signals, because those cards use different mechanisms in Labview for timing and synchronisation.
Can anybody tell me, how I can synchronise the clocksignals and let them use the same trigger (actually I want to use the external trigger of the 5112)? Witch VIs do I have to use?
Thanks in advance
Oliver

Hello!
First of all many thanks for your reply.
Exporting the external trigger from the 5112 to 6220 via RTSI works.
Synchronising the clocks in the same way as you wrote doesn't seem to work. May be I did something wrong.
What I did was the following:
I exported the "reference clock" signal of the PCI 5112 using "niScope export signal.vi" to RTSI 7.
Than I used the daqmx "sample clock.vi" to configure the
clock. I used the instance "sample clock" with "dev1/RTSI 7" as
the source (dev 1 actually is PCI 6220) and as sample mode "continous
samples". I started the PCI 6220 (daqmx) first, after that I started
the 5112 (niScope).
Running this vi I get the following error:
"ADC conversion attempted before the prior conversion was complete.
Increase the period between ADC conversions. If you are using an
external clock, check your signal for the presence of noise or
glitches."
This is still a small problem, but meanwhile I came to a bigger one:
I thought I could use the 6220 in the same way I can use the 5112:
I want to fetch (or read) data on both cards contionously but also
periodically. The period time is given by the External trigger I
mentionend before. Till now I didn't find a way to aquire the data from
the 6220 in records of a given length (let's say 100 samples, at 1kHz)
every time the trigger occurs (External Trigger rate is about 250 Hz).
This is possible with the 5112 board, but I wonder if this is also
possible with the 6220?
Kind regards
Oliver
PS: Sorry for the "witch"

How to simulate testing of PCI 5114 high speed digitizer

I want to use PCI 5114 board and want to interface it with LABVIEW 6.0 using NISCOPE VIs. I am a beginner to NISCOPE digitizer. I want to test my small application made for 5114. I don't have 5114 at present. Kindly tell me how can I simulate this boards and its input and Ext trigger.

Thanks Mr. Nathan.
My previous two posts were for me to understand how to check an application I had developed in LabView. As digitizer card is not with me at present so still some doubts are there. Let me specify in brief what I want and how I am achieving.
A repeated pulse signal of given duration (10 microseconds) at channel 0 is to be acquired. Repetition rate is decided by the trigger pulse available at Ext. Trigger. More clearly when ever trigger pulse (approx. Every 100 microsecond)) appears I have to acquire Channel 0 signal for 10 microseconds. Sampling rate is 100 Mega Samples per second.
I have used following blocks in given sequence: Initialize with Options (for simulation), Configure vertical, Configure Horizontal (sample rate=100MSPS, rec length=1000, num of records=1, ref positon=0), Configure trigger (edge, level=0.1, source Ch0 (for simulation purpose)), Initiate Acquisition, Multi Fetch WDT (num samples=1000).
Please tell whether I have to put Initiate Acquisition, Multi Fetch WDT Vis in while loop or only Multi Fetch WDT in while loop so that I can fetch all the data on each trigger.

Frequency measurement with High Speed Digitizer using External Trigger

Hello:
I have a

Hello Brooks:
Thank you for attention !
I will try to explain my application:
I need to measure a signal of a speed/position sensor. This sensor works with hall effect principle and is placed in front of a wheel with some teethes. Is used for automotive purpose in CAM and CRANKSHAFT applications. So, I need to measure period, duty cycle, rise time, fall time, Vpp, Angles for each teeth x encoder, everything from 40 to 7500 rpm.
I'm using CH0 to measure a signal of this speed/position sensor.
I'm using CH1 to measure a signal of an encoder connected to wheel.
I'm using EXT Trigger to sync acquisition with encoder's INDEX signal.
I need to measure the frequency of EXT trigger to know the instantly speed of the wheel.
So, If I know that my encoder has 2048 pulse/rev, I can measure FFT_FREQUENCY of CH1 with scalar measurement functions and calculate the speed !
The NI-Scope is wonderful because it can measure a lot of things automatic and fast, like period, frequency, duty cycle, rise/fall times ...
Now I have one more question:
I want to use 10:1 attenuation but I can't use a common probe. I want to connect the CH0 to sensor with a special connector.
I've tried to make the same circuit with 9MOhms and capacitor like explained on site, but I reached bad results. The industrial probes has special characteristics for capacitance and noise rejection.
Do you know how can I solve it ?
Thank you.

Frequency measurement with High Speed Digitizer using External Trigger

Hello:
I

Hello;
That is happening because you are doing Software timed operation, and since Windows manages all tasks that runs on the machine at any given time, your VI might take different times to execute, and that might be enough for you to miss some pulses.
The best way to do that is by using a 660x board, and have three counters doing the job. The firts counter can be configured as the first pulse train generator, the second counter can be used to generate a pulse that will trigger the third counter of. That pulse will be generated when the delay of 90 degrees is reached. So, the second counter will count events and will be triggered of by the pulse train generated by the first counter.
The third counter is configured as triggered pulse train generator, and t
he output pulse of the second counter is used as the trigger pulse for the third counter.
If you don't use that approach, you won't be able to reach fast speeds and might also miss some pulses, due to the Software timed approach.
Hope this helps.

NI5922 High Speed Digitizer - Antialiasing digital input filter

Is it possible to acquire a signal with the NI5922 board, without the antialising digital input filter?
My application doesn't require the antialias protection, and It would be useful the avilability of the full Nyquist band.
Thanks for your answers.
Natalino Roberto

There is no way to disable the alias-protection in the 5922. The
cutoff frequency of the digital input filter varies by sample rate, but
the ratio is constant (cutoff freq = .43 * sample rate). If you
need a wider bandwidth, you will need to increase the sample rate- but,
keep in mind that this may decrease your resolution, since the 5922 is
a flexible-resolution digitizer.
You can configure the type of the digital filter. Refer to the
documentation for the NISCOPE_ATTR_FLEX_FIR_ANTIALIAS_FILTER_TYPE
attribute (Vertical:Advanced:Flex FIR Antialias Filter Type in
LabVIEW). You can configure a number of different options for the
5922. However, the option with the highest bandwidth is the
default setting that I discussed above.

I owned an Apple Tv and since I upgrade my internet to higher speed my Apple Tv does not work. Please someone help.

In most scenarios you shouldn't need to forward ports, however if you need to, you may be best contacting your ISP.
As with most router issues, I would recommend that you contact your ISP with details of your problem (assuming that it was your ISP that provided it to you).
There are simply too many manufacturers with different software features and settings and often different names for such features and settings, that the best advice will likely come from those that are knowledgeable about your particular router.

How can a session be setup between two MacBook Pro's at different locations on high speed Internet connections, be setup to have a live recording session in Logic?

My partner and I live on opposite sides of the valley here in Phoenix. About 50 miles apart one way. We are Musicians and are working on a commercial for television, and would like to know if there is a way, between FaceTime and Logic, that we can configure our MacBook Pro's to record sessions together without having to be at the same house? When we FaceTime, he can hear my keyboard through his headphones, but we can't seem to get the signal routed into Logic and register to a track when its record enabled. Is there a way for us to save gas, and record at seperate locations, so he can engineer me and I can engineer him, while we build this project in Logic and Final Cut? Here is what we are using, we have nearly identicle setups, which was planned so we might be able to do something like this. Both of us are using Mid 2012 15" MacBook Pro's with 2.6GHz Intel i7 processors and 16GB RAM. The only difference between the two MacBooks is that his has an Optical Drive, but I removed mine and replaced it with a 2nd SSD Drive, so I have two Samsung 840 Pro's each with 512GB in my MacBook Pro. His just has one Samsung 840 Pro with 512GB. We both use Focusrite Saffire Liquid 56 Firewire Audio Interfaces, and we both use Logic Studio 9 Academic. I don't know if you need to know what we are using in order to help us figure out how to configure the MacBooks for a live session, so I figured I would give you those details just in case. If you need any more information, just let me know? Oh, we both have high speed cable Internet connections. Mine is 150Mbps speed which is the absolute fastest I can get in my area. And his is only a 50Mbps speed line.
Again, what we are looking to do is have a LIVE recording session, in Logic, with him at his house and me at my house. When we FaceTime each other, we can pretty much hear each others keyboards as if they were part of the conversation, and as crystal clear as we can hear our own when recording, but we can't seem to record enable an Audio track in Logic and route that keyboard signal into Logic and record it so we can engineer each other without either one of us having to drive to the others house, to be there to do it. If any of this even makes sense, I'm not quite sure how to better explain it. So hopefully you get what I mean, otherwise just say so, and I will try to do a better job explaining it. :-)
Anyone who can help us with this little problem would be greatly appreciated, and quite a hero in these two humble Musicians Worlds!! So from both of us, THANK YOU in advance for any input you might be able to give us. I look forward to hearing any and all suggestions.
Scott

Hey Scott
You and ALOT of people are attempting to do this, myself included.
Unfortunately at this point (to my knowledge) it's a pretty CRAP setup involved that will likely leave you frustrated.
HOWEVER:
A few things CAN be done:
IF you are getting live audio from your partner over the internet, you can re-direct that audio directly into Logic using a program called SoundFlower.
There are a few alternatives to SoundFlower, like JackTrip, and.....(the name eludes me)
(SoundFlower is from a company called Cyling 74 who also makes Max MSP. )
Once in Logic, you set your audio inputs to the track to be Soundflower. (either 16 inputs, or in this case 2)
That all being said, regardless to speed, you are still going to experience latency in the connection, and THAT is the part that will likely drive you to the mad house.
THIS all being said, I believe there are websites out there that are set up to actually do this kind of thing, (at least there WERE) but likely membership costs, and other "hidden" problems that you only learn about after you have signed on the dotted line. (Hopefully I am wrong?)
If you don't need to do a "live jam", there are always solutions like DropBox that work very well for exchanging large files quickly.
If you want to record live MIDI input from his keyboard, I am unaware of any solutions for this.
Due to the popularity of the iPad, you might want to look into the App store, and see if there is something available.
Good luck!

How can I stop spam from someone called AT&T High Speed Internet? I do not know what the email address is.

I am receiving 100's of spam emails. They are all advertising different types of products but they all say they are from AT&T High Speed Internet. I have used the junk filter on them but it does not pick them up as junk. I have to do it manually each time. I have contacted my UVerse provider and they cannot assist because it is getting through Yahoo to Thunderbird. They say that it is a problem that I will have to have assistance from Thunderbird to resolve so that I can have this listed as junk and will not have to do this manually. I am at my wit's end. Please, please help me!

Yahoo has its own junk mail filter (Spamguard), which you should confirm is enabled:
* [https://help.yahoo.com/kb/mail/stop-spam-yahoo-mail-sln3227.html Mail Help | - SLN3227 - Stop spam in Yahoo Mail]
The significance of this is that marking messages as junk in Thunderbird probably isn't integrated with Yahoo's system, so Yahoo may not be getting trained to block them. You might need to go into Yahoo from time to time and mark accumulated junk as spam.
Separately, there are solutions for filtering spam on your computer as the mail is downloaded from Yahoo. Thunderbird has a built-in filter, as described here: [[Thunderbird and Junk / Spam Messages]]. However, if that isn't as effective you would like, there are third party products as well.

How do I use the High Speed Data Logger with multiple I/O devices?

I am using the High Speed Data Logger vi to read from a 16 channel A/D card (NI PCI-MIO-16E). The project may require more than 16 channels. How can I use High Speed Data Logger to read from two A/D cards? Will it be able to write the data to one file?

The High Speed Data Logger vi will not acquire and right to multiple DAQ boards at the same time without modification. LabVIEW is more than capable of doing this what you are trying to do, but you will have to modify the code.

I just set up an Optus Cisco DPQ3925 wireless router to access higher speed internet I signed up for. I have a 4th gen airport extreme I want to put in another room and use as a wifi extender the wifi but I get an error message each time I try. Help?

Hello all.
I have just set up a new cisco DPQ3925 wireless router that Optus sent me to be able to access the higher speed internet I have signed up for.
I have a 4th gen apple extreme that I want to use to extend the wifi but when I try to update the settings via the airport utility I get a message that says it cannot do so, and to check it is in range and the wifi is set up correctly. I'm not experienced with these things but I can't think what I have done wrong.
Is anybody able to help me please.

You cannot use the AE to extend wireless from a non apple router such as your cisco modem router.. they are not compatible..
You need to tie to the two devices together either with ethernet or something like EOP adapters.. They are about $120 and you can price match in officeworks.
