5142 channels

Hello

My question is how to scan data using the channel 0 and channel 1 of a digitizer simultaneously. I did two files of VI for this race on 5142 channels 1 and 2 using two different anttenas, but when I run one another is arrested. or when I try 2 run two simultanoiusly error comes according to which no appropriate handle found and "niscope close.vi" flashes and a VI is stopped.

Concerning

MADD

Hi malala.

The justification is in the block diagram of the 5142 and specifically the block schema of the OSP.

Note that in the 5142 CH0 both CH1 are routed to the block of decimation and OSP. See the image below:

Notice now that in the OSP itself, both channels 0 and 1 are used in CDD for downconversion. See the image below:

As you can see, both channels are used for features in OSP even if the source of the data came from a channel of the ADC. For this, we essentially route information ADC0 CH0 and CH1 and perform the operation of the PSO.

If you want to use CH0 and CH1 independently, you limit yourself to only - decimation Digital Downconversion and complex baseband is not possible.

Kind regards

  • OR PXI-5142 niScope errors of simulation (0xBFFA4A3B and 0xBFFA408C)

    In development, I'm looking for work with the drivers of the simulation.

    Inside of MAX, I put session pilot "niScope" to simulate with specific driver (I also tried simulate with nisScope and the result was similar)

    Here is the set of instructions that I call:

    niScope_init ("Scope", VI_TRUE, VI_FALSE, & instScope);

    niScope_SetAttributeViBoolean (instScope, "", NISCOPE_ATTR_DDC_ENABLED, VI_TRUE);

    niScope_SetAttributeViBoolean (instScope, "", NISCOPE_ATTR_DDC_FREQUENCY_TRANSLATION_ENABLED, VI_TRUE);

    And NI SPY says:

    > 3.  niScope_SetAttributeViBoolean (0x00000001, "", NISCOPE_ATTR_DDC_FREQUENCY_TRANSLATION_ENABLED, VI_TRUE)
    > PID: Thread ID 0 x 00000520: 0 x 00000954
    > Start Time: enter the duration 19:56:43.495 00:00:00.047
    > Status: 0xBFFA4A3B

    Here's the development:

    Vital statistics: Property specified is not supported by the device or is not applicable to the task.

    Property: Enabled frequency translation
    Channel name: 0

    State code:-200452

    Now, if I enter the string "model: 5142; "BoardTypeXI" or "model: 5441; BoardTypeXI. MemorySize:268435456"in the program of driver installation, to ensure that the simulation is to take the right hardware, when I start acquisition here is the result of NI SPY:

    > 28.  niScope_InitiateAcquisition (0x00000001)
    > PID: Thread ID 0 x 00000778: 0x00000EA8
    > Start Time: enter the duration 20:33:15.452 00:00:00.000
    > Status: 0xBFFA408C

    with the development:

    DDCS more exist in the device is activated.  Note that some devices have less DDCS channels.

    Device: __tp3

    State code:-214233

    Does that mean error? According to the NI5142 specifications, there should be in Quadrature DC as well as the decimation of baseband. What I want is to send a signal IF to CH0 and perform the downconversion quadrature during extraction of signalthen interleaved to complex values.

    Please let me know what I am doing wrong. It is possbile to simulate with specific driver?  I really need it because I prefer to implement on my desk before you try my code our NI PXI-1042 q embedded system.

    BTW, I noticed that if I want to change any other CSD related ATTR say NISCOPE_ATTR_DDC_CENTER_FREQUENCY I get the same error.

    Thank you

  • Motu 8 pre distorted his left channel

    Hello

    I bought a MacBook Pro 2014 2, 2 GHz i7, 16 G memory vivid and connected my Motu 8 pre via FireWire-> love at first sight. When you use it with Logic Pro 10.2.4 is immediately created questions about my left channel. The noise on the right channel is good, but the sound on the left channel is really distorted with a high cry inside.

    Even if I play music via iTunes for example which is good and I start logic the left speaker (always play music from iTunes) is distorted with this small high inside.

    I saw something posted by MillerU812 and tried all of the suggestions, without success.

    Any help would be much appreciated!

    Have you tried the reset.

    Unplug the computer. Hold the Volume button in 5

    seconds. You must first see the light flashing clock, then the first LED

    for analog input 1 or 2, then you will see a "D". Turn the Volume knob to the right until the display shows "OK". Device is reset.

  • When released the 64 bit version of Firefox to the main channel?

    When released the 64 bit version of Firefox to the main channel? I thought it was supposed to be released when version 39 came out, but I must have been confused.

    No version passed was a guarantee of having Win64 for liberation, but more of an opportunity or that there has been speculation that Win64 builds on the beta channel from 37.0b2 build target.

    I guess you mean the Win64 (64-bit for Windows) and not on Mac OSX and Linux built which has 64-bit commercial for Firefox 4.0 versions both because easier to do and that it.

    If all goes well the Firefox 41.0 will be the first version to have Win64 rests alongside the 32 bit Windows builds.

    Win64 version was planned no version of Firefox. Then, on short notice for a brief period of a few weeks before Fx 40.0 version Mozilla thought to Win64 Fx 40.0 release but was changed to 41.0 Fx.

    Two things of note for versions of Firefox Win64 starting 41,0 + release. Only 64-bit Flash Player is white listed to run in Firefox Win64. Seconed we need 64-bit Windows 7, 8.x and 10 as the 64-bit Windows XP, Vista and server cannot run Win64 builds from Firefox 37.0 + development relies.

  • Why is the video from popular websites (for example Weather Channel) blocked on my Firefox?

    I recently downloaded Firefox on a PC, it is my default browser, and everything worked fine. I added extensions including Ghostery and add block more that work very well on my other browsers and I think on Firefox for a while. Now I can't get the video to work on popular websites (e.g., the Weather Channel), even if I disable Ghostery and add block more that I don't think that is the problem anyway. So I messed up something. Any thoughts would be appreciated.

    A frequent cause of script errors does not work on sites that use Flash is the feature of mode of the Flash player plugin. This feature has the security benefits, but it seems to have serious compatibility problems on some systems. You can disable it using the page modules. Either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click on Plugins. On the right side, find 'Shockwave Flash' and click on the link for more. Then uncheck the box for "Enable Adobe Flash protected mode" and try it for a day to see if that helps you.

    The Cowboys site certainly uses Flash. Do you get the commercial of the pre-roll for Dallas advertising or no video at all?

  • Grouping of external midi channels

    Hello

    I'm trying to combine two external midi channels, but it does not work.

    I can put them in the same group, I have check the volume, but it still moves only a fader when I'm not touching her.

    I tried to stack them, but the created VCA group does not send the midi volume information

    Is there a way to do this?

    Thank you

    Be careful with the external MIDI in general channel strips. In the mixer, they resemble other Types of Channel Strip, but they are not. External MIDI channel strips don't "carry" any audio signal, the only signal of MIDI. I guess that's maybe the reason why the Faders group.

    It's a bit of a (misleading) confused situation, because there is no indication in this regard. The other grouping settings, however, work on all the channel strips: editing, automation Mode, Record, color, Zoom, track to hide track.

    Don't use Solo and Mute for groups or external MIDI channel strips, they are incompatible between buttons on the tracks and channel strips.

    Here's the group settings that you can use on external channel strip

    Hope that helps

    I've been on the beta channel for centuries and have found this problem for some time. Many Web sites meet that my browser is not up-to-date, as the Mozilla site done before asking this question, but when I check updates the answer is always that the browser is up-to-date.

    Why?

  • How can I get multi channel audio via the HDMI port on an early 2015 MacBook Pro?

    I try to get the 7.1 audio channels to flow from my MacBook Pro to a cinema set up. The display works fine now I plug the HDMI in however the sound still Mac speakers. I checked the settings and no HDMI output is available. An airtime option is available, but that returns only two channels as a maximum to the receiver. When I go to the configuration of the source on the receiver it receives video at 1080 p 60herts however it is specifically stated No Audio from the Source.

    Also, I have connected my iPhone 6 s more using an Apple through the same HDMI cable adapter and it works perfectly. We also use HDMI with our PS4 occasionally and it works perfectly, even with the 3D.

    Thus, the MacBook Pro is early 2015 with an i5, the receiver is a Harmon Kardon AVR 2700 (we run 7.1 channels of this) and we are connecting via the HDMI port through a 50 ft HDMI before. The receiver sends the audio to a projector with 1080 p 60 hertz if it changes anything...

    Also if it helps the receiver supports dts - hd master audio decoding, Dolby True HD/Digital Plus decoding, HDMI 1.4 (HDMI is compatible 2.0), as well as multi-channel input and PCM and linear PCM.

    I use a "Behringer UCA202' audio device I bought on amazon.com for only $29.

    It works very well for the audio 5.1 or 7.2. Works connect optical toslink. Just plug it into a usb port on your Mac and a cable optical toslink to your AV receiver.

    My Yahmaha 7.2 audio/video receiver is measuring process the digital signal in THX, DTS, Dolby digital Pro logic, a cinema, etc.
