Using input hardware filter from PXI-5122 with niscope LV driver

Hello,
In my application I want to use the input hardware filter of 20MHz at the input to reduce noise during the measurement. In the NIScope driver I can configure my input with a "Maximum frequency". When I put this on 20MHz, I don't notice any difference. My question: Is this the right way to configure the 20MHz Input filter?
Kind Regards,
Joost

One problem may be that few of us on this forum are familiar with the hardware. Why not try posting in the High-Speed Digitizers forum?
Really, someone at NI should have replied to your post by now, as it is their policy to address all unanswered support questions themselves. They have the ability to route your question to scope specialists internally, so it shouldn't matter where you post. Maybe this one fell through the cracks, in which case you'll just have to keep yelling, or maybe--though you shouldn't have to--repost.

Synchronization NI PXIe 5122 with NI PXIe 6356

Hi,
I'm trying to synchronize NI PXIe 5122 (100 MS/s, 14-Bit Digitizer/Oscilloscope) with NI PXIe-6356 (Simultaneous X Series Data Acquisition). Does anyone have any example that can be useful (about synchronization NI PXIe 5122 with some DAQmx card, such as NI PXIe 6356) ?
Regards!

I bought a used macbook air, it didn't come with the flash drive to do a factory reset. Can I download the info needed and save it to my own flash drive and then do a factory reset? If not what can I do?

If it originally shipped with Mac OS X 10.6.8 or earlier, click here, phone Apple, and order a replacement.
If it originally shipped with Mac OS X 10.7 or newer, restart it with the Option, Command, and R keys held down.

Using the Matrix Sequencer from Reason Rewire with Audition

Hello. I've been trying to copy the pattern I've made from the matrix sequencer into audition using rewire. Everything's all hooked up. I've tried exporting one of the patterned tracks as a midi file from the matrix and gotten so far as importing and seeing that the new midi track in Audition sees the note pattern as well as the Malstrom synthesizer. I just can't seem to get the track to be copied into Audition. Any suggestions?
Thanks!
-Christina.

There's no way to *directly* copy a Matrix pattern into Audition (or any other Rewire host). The only way to do it is to use the "Copy Pattern to Track" function. The process is fully documented in the Reason 4 Operation Manual (PDF) installed with Reason - see page 302. In short, this function copies a Matrix pattern to the Reason sequencer track for the Matrix.
The reason your export to MIDI file didn't work is that Reason only exports notes recorded in its sequencer. Matrix patterns don't get exported.

In theory yes, but the Apple (Boot Camp) bluetooth drivers aren't working vary well it seems.
Try a search in the forums and see what you can find.

How do I use the a command from a .dll with labview?

I want to use for example the M8784Open() command to control an M8784
photon counter. I know how to place a call library function node
but don't know where to go there. The user manual for the photon
counter has the following explanation of the M8784Open() command but I
don't know how to use their advice in labview!
7-3-1 M8784Open( )
Declaration HANDLE M8784Open( BYTE Board );
Parameter
BYTE Board
Specify the board to be used: M8784_MASTER or M8784_SLAVE. Specify both
when making 2-channel measurements simultaneously. It is not possible
to specify M8784_SLAVE only.
Return value A handle for the M8784 is returned when the function has succeeded..
INVALID_HANDLE_VALUE is returned if the function has failed..
Explanation Calls a handle to allow the M8784API.dll to use the M8784.sys driver.
Hereafter, specify this API’s return value (handle) when using other APIs.
When quitting M8784 operation, call up M8784Close( ) to cancel the driver.

You need to find out the equivalent number of the parameter. Somewhere in your documentation, or inside a file (for example, a header .h file in C/C++) you will find the definitions of each parameter.
For example, M8784_MASTER may have the value 1 and M8784_SLAVE the value of 2. You already know that it is a BYTE, so it will be a number of type U8 in LabVIEW. You need to find the exact values.
Probably, by value "A" it means the hex number "A", which is 10 in decimal. You need to find that in your documentation.
You also need to find the type HANDLE. It can be a BYTE, etc. Once you know that, find the value of INVALID_HANDLE_VALUE, so you can test for the error.
Most of this information can be found in the document Using External Code in LabVIEW. Check your help file, or check this link.

Enrique

Using LabView and Modbus to Communicate with AKD Servo Drive

I’m working on a project to control a Kollmorgen AKD servo application using Modbus directly from LabVIEW. I’m new to both LabVIEW and servo drives so forgive me if this seems simple. I have established communications to the drive through Modbus and have been successful at some rudimentary control of the servo. I know the drive only supports "Write Multiple Registers” and “Read Holding Registers” functions and there are scaling factors that need to be applied. What I need is some help with taking the Modbus information supplied by Kollmorgen for each command and formatting it for communication to the servo and vice versa. I need to understand how to take the supplied 8, 16, 32, and 64 bit information for commands, scale it, and format it into the two or four registers required for the drive to read the parameters. In turn, I also need to understand how to take the same information and read it and scale it from the drive. I’ve attached a spreadsheet with the particular commands I’m interested in and a sample VI that seems to work for speed control but to be honest, I'm not sure how/why.

OK, I've got the ability to read values from the AKD drive pretty well sorted out. I'm now having trouble with the ability to write. I want to use Labview to program Motion Tasks in the AKD drive. To do this I need to perform three commands: MT.NUM (specify the motion number), MT.P (specify the angular position), and MT.SET to set the parameters for the task. MT.P requires sending a 64 bit signed float or a 32 bit signed float (requiring four or two registers respectively). I used ModPoll to see what values the drive held in the MT.P registers after entering the desired angular position using the AKD Workbench software. For example: using Workbench I entered 234.567 for the angular position and read 208 and -32506 from registers 2060 & 2061 (the 32 bit registers for MT.P). After scouring the forum I put together the attached VI to try to write to the same registers but I can not seem to get the translation of the input (angular position) to the register values correct (entering 234.567 does not produce 208 and -32506 in registers 2060 & 2061). Anyone have any ideas?

New Mac - transfer from previous TM with multiple hard drive backups

I just got a new Mac Pro. Previously I had a PowerMac G5 running Leopard which had two internal hard drives being backed up using Time Machine. When I started my new MacPro (running Snow Leopard), I selected transfer using Time Machine, but it only found one hard drive (my boot drive) and not the drive with all my files on it. How do I transfer this other drive? My new MacPro also has two internal hard drives so that I could have a similar setup.

You can probably use the full restore procedure, per #14 in the Frequently Asked Questions *User Tip* at the top of this forum.
Just be sure to select the "other" drive on the screen listing the backups (the 5th point in the green box of #14).
Sometimes, however, it will only let you select the boot disk. In that case, back out, restart normally, and restore from the normal "Star Wars" display.
Since you're on a different Mac from the backups, you'll have to use the procedure in #E2 and E3 of the Time Machine - Troubleshooting *User Tip* at the top of this forum.
Don't restore the entire folder representing the second disk; select all the top-level folders and restore them.

Migration to new IMAC from old IMAC with a Backup Drive

I purchased an new IMAC and have an old IMAC and have migrated all of my stuff from old to new, except I have a external backup drive on the old IMAC and did not migrate it. I thought that I would migrate by attaching it to the new but do not have the right cables. Can I connect the backup drive to the old with the firewire that I have and connect the old IMAC to the new one with the cables that I used, or do I have to buy the right connector to connect the backup to the new IMAC.
Thanks

How to setup new notebook from HP laptop with bad hard drive

Got kids a new Hp laptop in June. The hard drive has been getting progressively louder and is obviously about to go, with a blue screen error forcing a roll back of the computer. I have done a full backup to an external hard drive and I am returning this for a replacement. Should I make a recovery disc and reinstall from the disc when I get the new laptop, or should I just plug in the external hard drive and transfer the files over? A guy at work says using the recovery disc is the way to go, because it would reinstall Norton and all the other programs we have installed., but I thought the external hard drive backup was supposed to be the way to do this
This question was solved.

Not sure I understand the question. "Should I make a recovery disc and reinstall from the disc when I get the new laptop, or should I just plug in the external hard drive and transfer the files over?" Usually HP replaces only the hdd.
If you are receiving a new hdd to put it the laptop, yes you need to burn the Recovery Disks to reinstall Windows & original software on it. You can then use your backup to restore files.
IF the full backup you are referring to is a complete System Image, it can be used to restore Windows, programs and all files,etc on the new hdd. You do need to also burn the Repair CD to boot from and restore the System Image on the new hdd.(I would still burn a Recovery DVD set to have as a fallback)
If you are receiving an entire laptop replacement it will have everything installed on it. You will just have to restore your personal files from the backup

Question about sample rate and PXI 5122

Hello! i am new at using labview and pxi cards. i am trying to sample a signal from an analog gennerator with pxi-5122 so afterwards i can process the samples and extract the processed samples to an oscilloscope through pxi-5421. i tried to use the labview examples for pxi-5122 for sampling and processing( more precisely the example "digital filtering"). They are working perfectly for high sample rates (some MHzs), but when i try to sample low frequency signals (for example 20kHz) and use sample rate according to Nyquist criterion, the acquired samples dont reconstruct the initial signal at all. if you have experienced similar problems, how can i sample low frequency signals with sample rates according to Nyquist criterion?

Nyquist criterion says: "sampling freq. should be at least twice the max. feq. component in the signal". For better reconstruction you should keep the sampling rate to some 8-10 times of max freq. component in the signal.
I am not allergic to Kudos, in fact I love Kudos.

Restoring from Time Machine after 1T hard drive replacement

I am a super computer novice. I picked up my computer yesterday after having the recalled Seagate hard drive replaced. I backed up my computer using Time Machine before I took it in on a Seagate "Backup Plus" portable hard drive.
Now, when I have tried to use the restore start up, the computer recognizes that my drive is connected, but says there are no files on that drive it can use to restore the system.
I can see that there are 50GB on the disk, and when I look in it, there are files called "Macintosh HD" so that makes me think that my stuff is in fact on my external drive. why can't my computer see it?
Do I need to get a FireWire cord to connect to my computer? I'm using the USB 3.0 that came with the hard drive.
My computer had Mountain Lion when I backed it up. I think it is back to whatever OS it came with originally. Do I need to update to Mountain Lion? If I do, how do I do so without having to pay for it again? My app store is empty since my computer was wiped.
Thanks for the help, I really need it!

The first thing to do is upgrade back to ML, which you can easily do. Just redownload ML from the app store with the same AppleID you used the previous time you purchased the ML upgrade. Your purchase is tied to the AppleID you used when buying, so you can download it again (as many times as you wish) without payment as long as you use the same AppleID.
Once you have upgrade it to ML, then try the restore from the backup (which I gather was made when while running ML before).

Re-installing LR license on new mac with no optical drive

originally purchased LR2 with CD copy, have subsequently upgraded online to LR3 and LR4 using PC.
have now purchsed new mac with no optical drive, so how do I get LR4 reinstalled?
any upgrade licenses require you to have the original full license first installed.

any upgrade licenses require you to have the original full license first installed.
Used to be the case but no longer. Adobe's process is now much simpler.
All software versions (whether full or upgrades) include the full program code. The serial number you enter tells the installer if it's an upgrade or a full version.
Download the Lightroom 4.4.1 trial from http://www.adobe.com/support/downloads/detail.jsp?ftpID=5599
Install it then enter your LR 4 serial number. The installer will then ask for an earlier version serial. Enter your LR3 serial and the install will complete.
