Digitizer / Oscilloscope USB-5132 Internal Averaging Option?

The DS5132 USB digitizer / scope from NI does not support multi record acquistion. Multi record acquistion would allow to internally save multiple measurements triggered by hardware triggers and therefore significantly reduce the overhead that comes in when the unit is read out via USB. My question is, does the DS5132 driver support some kind of hardware averaging though? A lot of scopes have an averaging mode and it would be great if I could internally average waveforms before reading them out. That said, I am not sure how comercial table top scopes handle averaging and it might be just done via software.
Thanks for input,
Erik

Erik,
Unfortunatelly, like most of the NI oscilloscope product line, the 5132 only does averaging in software.

USB-5132 ext clock + Trig ?

Hi -
We need ~20 Mhz for 100mS samples, 8 bit , high clock accuracy with big (>3kV) isolation. We have been looking at a USB-5132 , with an optical-fiber to USB converter and supply 5V that floats with the source. We need it to sync with clocks to <10ppm, and while we could run PF1 from our isolated clock system, then we wouldn't have a trigger.We had been hoping to set up the 5132 to acquire whenever it saw a clock pulse, as we can gate or otherwise process our clock signals. I see from other posts though that the 5133 won't do continuous mode so probably not the 5132, eh ? Triggering from the inputs or in software is not an option, unfortunately (would have to trigger 500mS back) Also I had been hoping to find programming or detailed user manuals online but don't see them. Another option I suppose would be a 2 ch ethernet digitizer, but the low cost and ease of use makes the 5132 attractive, as this might be the first of a bunch more. Thanks for any input.

Hi Jennifer -
The page Matt pointed to, http://zone.ni.com/reference/en-XX/help/370592E-01/TOC6.htm , has the outline of a programming guide. Each link points to a valid page there, but I only found a bit on those pages, e.g.

External reference for USB 5132

Hello,
I have a couple (hopefully) general questions about using an external reference clock on our USB 5132 digitizer. We want to lock it to the other oscillators in our system, all of which are presently locked to one 10 MHz reference. If I connect our existing 10 MHz reference to the PFI1 input, my questions are:
1. Is the 5132 now locked to our system? Or, do we need to specifiy in the setup software that we want to override the 5132's internal reference and rely entirely our external reference?
2. In order to have the best possible lock, do we need to tell the 5132 to sample at a frequency that is evenly divisible by 10 MHz (e.g. 20 MHz, 10 MHz, 5 MHz, 2 MHz, etc.)? Similarly, are we worse off if we want to sample at say, 13 MHz?
Thanks for any thoughts.
Best regards,
Penny

Hello Penny,
1. Yes the 5132 is locked to your reference system 10MHz clock (with some offset due to delay in the time it takes to transmit the clock signal from your system to this USB device) if you selected the PFI line as the source of an external timebase. Please take a look at the following example Help>>Find Examples>>Hardware Input and Output>> Modular Instruments>>NI-Scope>>Features>> niScope EX External Clocking.vi.
2. No, although I would expect that if you enter in 13MHz and your device was not capable of doing this it would coerce it to the closest value. I would suspect that only integer divide downs from the clock in question are valid such that 12. 5MHz is the value it would coerce to if you were to request a 13MHz value (with a 50MHzexternal clock). The 5132 can not do RIS so sampling at 20MHz with a 10MHz SampleClock Timebase Source is not feasable.

Usb-5132 slow

Hi everybody,
our application requires collecting short signal waveforms (about a few thousand points at 50 MHz sampling rate) with repetition rate at least 20 Hz. We were happy before with Labview 7.1/NI Scope 3.4/ USB-5132/ Low end Dell laptop combination. The experimental setup allowed us easily collect data at about 100 Hz repetition rate.
Our data acquisition program is based on standard example program "niScope EX Configured Acquisition" from "C:\Program Files\National Instruments\LabVIEW X.X\examples\instr\niScope NI provides with every "NIscope" software.
We bought "Labview 2010 Developer Suite", which we installed on newest "Dell Precision M 4500" laptop. But we found USB-5132 now allows us collect data waveforms only at about 10 Hz repetition rate - 10 times slower then with old labview 7.1!
I tested the data acquisition speed with standard "niScope EX Configured Acquisition" program I mentioned above with the trigger set to "immediate" and found the same difference: the sample from NI Labview 7.1 works about 10 times faster compared to new Labview 2010 when the same usb-5132 digitizer is used.
Like I already mentioned, we need at list 20 Hz repetition rate, better more, and we would like to keep easy-to-use USB-5132 digitizer. Can we make it work faster with new Labview?
Thanks,
Yuriy.

Hello Yuriy,
My apologies for not seeing this post a few days ago when you originally posted, but Kyle recently brought it to my attention (I usually monitor the High-Speed Digitizers board but don't always catch posts on the LabVIEW board).
I have done some benchmarking with various versions of the NI-SCOPE driver and a USB digitizer. Unfortunately, it appears that there is an issue in NI-SCOPE 3.6 and later which is causing the fetch (read) rates to be drastically decreased with the USB digitizers. We are implementing a solution to correct this problem and get the fetch rates back to their previous performance values. NI-SCOPE 3.8 will address this problem, though that version will most likely not be ready for release until late Q1 2011. In the mean time, the best option is to downgrade to NI-SCOPE 3.5.2 or earlier if it is possible for the specific LabVIEW version in use. If this downgrade is not possible, please contact National Instruments support by phone or email with your specific details and we will work with you to determine the best solution.
We apologize for any inconvenience this has caused and we appreciate your help in informing us of this issue. Please let me know if there is anything else I can do to help out!

USB-5132 as gated integrator?

Greetings,
Can I use USB-5132 as a gated integrator?
I have a PMT signal with 1-10 kHz rep. rate. The signal itself lasts 2 us and I would like to slice this 2 us window into smaller bins and collect data in that specific window and integrate the signal.
I checked the manual, it looks like it does not have a built-in gated trigger mode. I am wondering if there is any wy around it...
Best regards
O.Birer

My problem is I could not figure out a way to sample the waveform within a gate. Can I use the rising edge to start acquisition and the falling edge to stop the acquisition?
(This is generic for all digitizers, not exclusive toe the 513x devices.)
Because digitizers/oscilloscopes take as granted that the window of time for which you wish to acquire is known at the time of the beginning of the acquisition, you cannot configure it to have a variable window size on-the-fly (without software intervention to stop and reconfigure.) This isn't done on the fly on any oscilloscope product I've ever heard of, from any vendor. In other words, the concept of "gating" an acquisition is not a concept natively handled by digitizers/oscilloscopes.
Work-arounds:
If you choose the largest possible gate time and set that to be your record length, then you can post-apply software to trim the data you don't care about.
If you can allow software/driver interaction with the instrument while your signal is generating, you can stop, reconfigure for a different record length, and re-start the instrument's acquisition again. Expect this could take a few milliseconds or more, depending on how you implement it.
In essence, I would like to time resolve the signal which lasts for 2 microseconds.
Is your signal repetitive? I can only imagine that acquiring several ~500ns windows of data with relative adjustments must mean your signal is repetitive.
Just for reference, see the Acquisition Engine for the USB-513x devices. You can see you will really only have two signals to work with to manipulate this device in hardware time: there is a start trigger (must be digital) and a reference trigger (can be analog or digital). You can send a "start" trigger or a "reference" trigger only to capture the constant amount of data which is (in some constant way) related to the trigger event you set.

Help. I have a Google Hangout in 40mins and my sound seems to have vanished. I went to Sys Prefs and it came up with Digital Out....and the Internal Speakers option is no longer there. How do I reboot, or fix this please?

help. I have a Google Hangout in 40mins and my sound seems to have vanished. I went to Sys Prefs and it came up with Digital Out....and the Internal Speakers option is no longer there. How do I reboot, or fix this please?

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. If not, the machine needs to be serviced. Inserting any kind of tool in the port may cause damage that won't be covered by the warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
11. Reset the NVRAM.
12. Reset the SMC.
13. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.

Internal/External option in the Transformation

Hello experts,
Please tell me about Internal/External option in the Transformation under Proposal Tab. When we go for Internal And when we go for external.

i think external is used when your source system is flat file. Normally the data from R/3 use internal format.
waiting expert to answer more detail.

Unable to delete internal Address via EDIT INTERNAL ADDRESSES option

Friends,
When I login as administrator, the EDIT INTERNAL Addresses option allow me to Add new address and change existing address. but there is no option avialable to delete internal address.
Can any one tell me how to delete internal address from WEB GUI screens.
Alternate way is to delete the internal address from SAP GUI business partner transaction. but i do not want user to access SAP GUI client.
is it an authorization problem?
Regards,
Sandeep Parab

Hi Sandeep
You are correct. no way to delete address number via web.
if you want to delete adress no. eye on adrc table.
if you want permanently delete all adress related to BP .
one bp is related to more adress number.
bupa_test_delete - so if you delete one BP and may delete all adresses it linked with.

Utiliser un câble coaxial 75 Ohms avec ni usb 5132

Bonjour,
dans le cadre d'un projet, je dois acquérir des signaux analogiques vidéo et l'une des contraintes et d'utiliser des câbles coaxiaux (BNC) 75Ohms (d'un côté parce que c'est de la vidéo et de l'autre car ils sont disponibles).
Une des solutions matérielles retenues (pas par moi) est le NI USB 5132, notamment au vue de son faible coût.
Mon souci est que l'entrée de ce numériseur est en haute impédance (1Mohm), ce qui n'est donc à priori pas adapté puisque dans le cas de transmission de signaux vidéo l'adaptation des lignes est primordiale.
Mais peut être suis-je dans l'erreur?
Sinon, existe -t-il un moyen simple d'adapter mon entrée de numériseur?
Merci
Rainette

Bonjour,
Effectivement, je pense qu'il faudrait utiliser un adaptateur d'impédance, disponible sur des sites spécialisés. Ou alors créez votre propre circuit imprimé.

Edit Internal Address option system will only hold one Ship to Address loca

When trying to add an new address using Edit Internal Address option system will only hold one Ship to Address location. Each time a new one is added it simply over-writes the existing address instead of creating a second address. Attached screenshots show steps taken and results. Problem is also occurring in SRQ, unsure when this started as we do not use this functionality on a daily basis.

Hello Vijay,
For one location you can maintain more than one address using Edit Internal addresses in SRM web application (SAP_BBP_STAL_ADMINISTRATOR role).
Select Edit Internal addresses --> Select your business partner --> Push create button --> Maintain the address and save. A new address number will be generated.
Maintained addresses will be visible in search help for the requester. One of them can be set as default in PPOMA_BBP attributes.

Why can't I get frequency info from NI USB 5132

Hello
I use NI USB 5132 and try NI Scope example measurement library.
I wonder why I can not get frequency info of input signal.
Thanks
Solved!
Go to Solution.

Thanks for kind responses.
I am using LabVIEW 8.6 on Windows vista and an example called niScope EX Measurement Library.
I am measuring the frequency using a clone called niScope Multi Fetch Measurement Stats.
I am using a pulser producing 60 3V-pulses /sec. When using Soft front panel. sometime I can measure the frequency but sometimes it shows "error."
By the way, I can't see pulse signal from the example but I can see the signal using SCOPE soft front panel.
the error message says
Possible reason(s):
Driver Status: (Hex 0xBFFA2002)
Unable to perform desired measurement operation.
Waveform did not cross the middle reference level at least 3 times. Check the low, mid, and high reference levels. If you are reading a waveform that has a small amplitude, you can use the attribute Hysteresis Percent to reduce the hysteresis thresholds.
Please let me know if more info is needed

Ripple Measurement using USB 5132

Hello,
I am trying to use NI USB 5132 to measure ripple (Vp-p) at the output of a DC power supply.
I not familiar with digitizers and having problems using the NI-Scope functions to create a VI that can measure ripple.
I have looked the example VIs, but not sure how to change the settings on the Vertical and Horizantal functions so that they work for me.
An help or inputs on this matter will be greatly appreciated.
Thanks.

The examples are as I recall pretty complete. What is the exact issue you are having?

Line-out or internal speaker option

I have my iMac hooked up to my home stereo with a mini to RCA cable and i am trying to figure out a way to switch from home stereo to internal speakers without having to unplug the cable every time. Any help would be great. Thanks.

Hello,
do you think i will be able to do it using the
optical output?
I don't know.
I edited my original post with a link to a program you could try.
Now, if that doesn't work, then I do have one other idea that just came to me.
You could get a USB audio output for your speakers. Now, with a USB audio output device, you would be able to change your audio output option using the "Sound" preference pane in the Mac OS X preference panel.
I think Griffin has a product for that.
So, that might be an option.
Hope this helps.
