About rise time test
Hi,
Use Transition Measurements to test rise time as appendix in detail.My question:
1. Is the program structure reasonable?
2. When the RAMP TIME of amplifier is fixed, the DURATION varies to the different time of input control Am.
3. The duration ERROR is out of allowance.
Hope you give me a resolution.
Thanks!

Hi Xu,
I understand that you are wanting to calculate the rise time of a signal coming into your NI 4472 board. I'm assuming the NI 5411 is stimulating an external amplifier? Please include more information about your application and the routing of the different signals involved so I have a better idea of how to best implement a solution.
Also, are you receiving an error with an error code when you run the program? Or is it just outputting a value you don't expect. If you are receiving an error please include the error number and the description.
The NI 4472 is capable of making rise time measurements but I would recommend using one of the NI high-speed digitizers which have built in functionality for making rise and fall time measurements. They also make much more precise timing measurements due to their higher sampling rates. If you have an NI digitizer I would give that a try. If you only have the NI 4472 then I can help with that also. I just need more information about your application.

Sine, Square & Sawtooth sweep generation with variable duty cycle/rise time & fall time
Dear All !
I request and need some candid advices on the subject issue keeping in view the following notes:
1) I am a novice in LabView.
2) I was an average Electronics Engineering graduate who graduated about 9 years ago and since then I have not been involved in Electronics Engineering.
I have undertaken a task or generation of Sine, Square and Saw Tooth wave forms. All these waveforms are to be frequency swept form 1 Hz to 100 kHz. The amplitude of all these waveforms should be able to be adjusted. The duty cycle of Square Wave should also be adjustable (or better be able to be swept). Likewise the rise time and fall time of sawtooth wave should also be adjustable (or better be able to be swept).
I am considering other options as well but wanna try it on LabView.
I wish to ask that is it possible to execute this task in Labview 7.0? If possible then considering the para 1 & 2 above, is it possible for me to finish this task in 15-20 days if I work on this for about 3 hours a day? If not then what can be reasonable estimate?
I will be extremely grateful if you people can offer advice on whole project or part(s) of it.
Thanking you in advance and requesting urgent response(s).
Solved!
Go to Solution.Check this thread.
I did some similar coding, it might be usefull to you.

I am using ver 9.0 though.
If you work 3hr /day for 2 weeks you might as well finish book basics 1& 2 and than can do whan you need in a breeze, couple of hours.
Good luck -
Pxie-6556 - How to control the rise time in the digital lines (hsdio)
Hi,
Is there any way to control the rise time in the PXIe-6556 digital lines?
Even in a low frequency signal 10kHz the rise time is about 2ns.
Tks,
Solved!
Go to Solution.Hello engfpe,
The PXIe-6556 is a 50 Ohm system, meaning the output is source series terminated to be 50 Ohms and all our cables and accessories are 50 Ohms. With this setup regardless of the data rate you should have a clean rising or falling edge regardless of the data rate. The quality of the output (rising or falling edge) at your device will be related to the impedance matching of your cables.
The PXIe-6556 cannot adjust the slew rate by itself. However you can insert some simple passive components to do this for you. I've attached below to images. The first is a schematic showing one way of slowing down the edge. The second is the a simulated waveform showing the original edge rate before slowing it down, and the slowed down edge. This simulation is not of the PXIe-6556 but instead a generic digital output for concept. In the schematic R1 is set to 34 Ohms because U1.8 has the additional 16 Ohms inside it. TL1 is the 50 Ohm output simulating the cable on the PXIe-6556. R2, R3 and C1 are components you could insert after the PXIe-6556 cable before it goes to your device/cables. In this setup the cable going to your device is TL2 which is also 50 Ohms but it could be another impedance in which case you would change R3 to match.
You can see in the attached images you can significantly slow down the edge with this setup by altering C1. I hope this helps,

Data migration completed what about next time
Hi Guys,
I have sucessfully migrate the data into a new system from our existing Quality server, this is just for testing the tdms implementation, but my question is what about next time, suppose i have migrated all the data from 1.08.2007 to till date and package has been completed, but when we start again we need to create another package i guess and if we need to change only the data selection date then do we have to go for all the step or is there any selective option for us.
Regards
SubhashHi,
Please see the help file. Here is an extract:
If no changes regarding the definition of the objects for transfer have been made, you can create a refresh package to replace the data in the receiver system with current data from the related sender system. You can specify a new 'from-date' for the time-related approach and include additional tables in the transfer.
The refresh package inherits the setting of the related configuration package, which means that you do not have to execute some of the steps that were required for configuration.
Procedure
Place the cursor on the related configuration package, and choose Copy for Refresh.

I am using a PXI 6733 AO board as output on a closed-loop PID control. There appears to be excessive lag on the output when compared to the error signal, and as an experiment, I gave an unbuffered 0-10V step output command to the card. I measured the rise time for 0-10V at the output (no load, directly connected to SCXI 1121 for acquisition) at approximately 200mS. This is nowhere near the rated 2.8uS...am I doing something wrong?
Sean,
I'm only acquiring at 1kHz, but I'm not really interested in the absolute value of the time, just need it faster than it is. My application is a real-time control loop operating at 500Hz, so 1k should be fast enough to show me the step response. In continuing my investigation, I have found that the 200ms time is constant regardless of the magnitude of step change (-10 to 10, 0-10 or even 0-1V). Makes me think that something somewhere is configured to generate a ramp, even though my code has set the buffer to zero. I also get the same rise time when I send a command from the test panel in MAX.

After updating to iOS 5 today, i was able to get my iphone working with virtually no problem. The issue i am having is that after i finished with my phone, i tryied to do the same with my ipad. Everytime it is plugged into itunes, it keeps saying it needs to restore over and over again. I have done this about 20 times today and have lost it. I can't sync anything with it, especially my music or calendars. Anyone know of a solution?
This will fix it

When I recently updated to the newer version of FireFox, (version 3.6.13) the DownloadHelper add-on was lost, and it will now not re-install, though I have tried about 5 times?? When I clicked the icon to download the add-on the download progress bar indicated that the download was underway however, when it had completed, the add-on appeared not to have downloaded - including no icon - not even if I search for one. When I tried to download the same add-on again, the download window indicated the download in a faded color and it seemed to be indicating that I already had the add-on. Try as I might, I can't get it to work. DownloadHelper always worked with no trouble on the previous version of FireFox. Are you able to help? Many thanks for this service!
Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the "Find Updates" button (Firefox 4: click the Tools button at the left side of the Search Bar) to do a compatibility check.
You can also try "Reset all user preferences to Firefox defaults" on the [[Safe mode]] start window.

I do not know what happened, all of a sudden Firefox does not want to work anymore. Had been conected to audible. Retried about 4 times.... no luck had to force quit every time. The three Firefox app. into garbage, emptied garbage and redownloaded new version from Firefox. Reinstalled but same thing happened again... no connection.
What can I do, I like Firefox better than Safari, had it for years on my Mac.
Please let me know.
(Note: I have also mentioned this on the automatic response to the malfunctioning).
'''''Email removed by moderator to protect you from spam'''''Hey.
I think it might be the problem with one of your plugins.
Try to uninstall the webbrowser AND remove the storage from Firefox in your user-account (Linux: /home/username/.mozilla). You can check the list of installed Add-Ons in Firefox under "Extras => Add-ons" or by pressing Shift + Strg + A (Linux). -
Some questions about a Time Capsule
Hi!!
I just have a few questions about a Time Capsule, but first let me explain the backgroud to my questions.
I live in a 2 floor house(including a basement) and my bedroom is downstairs. My parents currently have a desktop PC connected to our wireless router and our printer. Me and my step-father both have 13 inch MacBook Pros, and he uses the Mac like a basic computer, so the equipment connected to our PC is good for him. I, on the other hand, use my Mac, iPad and iPhone to their fullest potential. I am a SUPER MEGA NERD when it comes to computers, so I plan on making my bedroom an amazing office at the same time. So I want an AirPrint Enabled printer in my bedroom (Under 100$$) along with a Time Capsule to back up my information, because everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
If you don't understand what I'm trying to ask (Even though I feel like it's self-explanatory)
ONE question about the PRINTER: Do any of you have any recommendations for an AirPrint Enabled printer under 100$? Even under-150$ would be okay.
THANKS FOR ANY HELP!!!!everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
Don't just depend on TM.. use a disk image type utility.. either one of the Mac tools, SuperDuper, CCC, Chronosync or even a linux boot cd (if you have a cd/dvd drive still or via usb can boot) a great tool is Clonezilla.. it will do basically any computer, Mac, Linux, Windows.. and since it boots into its own OS can restore a computer in a flash. Then you can add the incremental changes from TM.
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
Actually I am surprised you get good wireless as usually directly above or below a router is often the worst spot. Time Capsule cannot extend the wireless of any other router than Apple.. it is a special system and only Apple can join the club. It has bad effect though, if you set the TC to extend wireless it turns off ethernet ports.. which is hugely dumb.
The best arrangement is ethernet to the upstairs.. or EOP adapters. If not then a wireless router that matches the existing unit will generally be better than mixing apple and non-apple.
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
You create a new wireless network by selecting manually the wireless channel and use different wireless name, ssid and security. There are 3 available channels on 2.4ghz.. your existing router will use one or two.. depending on if the setting is 20mhz or 40mhz.. so you need to manually set everything and not use auto.
TC is slow on 2.4ghz cf 5ghz and there are many more channels at 5ghz but not everything can use it.. iphone for instance is 2.4ghz only . whereas ipad can use 5ghz.. most full computers now can use 5ghz.
Buy a wireless network printer. Or alternatively an ethernet network would be also ok but now are more expensive than wireless ones. Network printers are not much more than straight USB and work much better.
I do not use airprint so have nothing to offer.. find the best HP model in your budget.. but others may have had more experience.. I use ethernet connected b/w laser business type HP.. they work great.. but airprint is too recent an innovation for me. -
My ipod touch is not showing in itunes therefore, not syncing. I've gone through the trouble shooting steps about 5 times.
Did you try here:
iOS: Device not recognized in iTunes for Mac OS X
If you have iTunes 11 turn on the Sidebar. Go to iTunes>View and click on Show Sidebar. You can also do a Crtl+S to show the sidebar. The sidebar is where Devices appears. and Control+B to show the Menu bar
Next try on another computer to help determine if you have an iPod or computer problem. -

So I have tried to update my iPod touch about 5 times now and it still says there is an error. I,ve erased all my settings and attempted to restore it, but it wont let me. I'm ready to throw it away and find a new product
Errors when updating leads to corrupt system files and this may be your problem. If you're using windows, connect your device to PC and run any third party app like Syncios. If it detects, you maybe in luck and try to back-up your data if possible. I hope that it won't and if doesn't, there is no other way to recover files. You should be restoring with iTunes and all data will be erased, or else your device may become unusable.
