Problem of Earth / Circuit Design

Dear community,

in advance, I thank you, I hope this is the right place to ask this kind of question.

I would like to design a very small preamplifier pre - one preamplifier because it is mounted on the head of the insect to behave and a later analog frontend for the conditioning of signals and an additional gain. Unfortunately, I have major problems with respect to the ground.

Please see the attached PDF file:

(1) the preamplifier must be supplied with a supply separate power source such as a battery. as I need a dual power supply, I would use just two batteries connect them in series and take right in the middle like that is usually connected to the GND pin 0V? so in this case I would connect the preamplifier power supply 0V to the same connection as REF?

(2) the shield of the cable from the head to the preamplifier should be connected for the Earth also the chassis of the preamplifier. In this case, I would like to use the net power to which I have access to the preamp power which is made with normal voltage rectifier/regulators (I know that there are missing parts )

the 0V of the preamp power supply should be linked to the mass of the filter etc. steps that finally end in the GND to my A/D card of NEITHER? right?

(3) now, I have to admitt that I did not the differential amplifier in scene myself and it actually makes me a problem because here's an op amp used to excite the input of the differential amplifier and this op amp is that related to these TWO grounds: the virtual mass to the head and the GND AI through the op amp. I unfortunately have no idea what this op amp is doing?

So, it would be great if someone could tell me if my grounding considerations are right especially with (AI GND) and what does the op amp out and if I should use referenced asymmetrical pattern of NRSE.

ManyManyMany thanks to you all,.

Yours,

Prefrontal

Thank you!

Kind regards

  • Impossible to update Circuit Design Suite 10 to 11. No license for 12.

    Hello everyone, I have a license for Circuit Design Suite that covers version 11 and I have version 10 installed. I have a project that I need to work on that was originally in version 11 on another computer. It cannot be opened with version 10. I downloaded the update of version 11 of the site OR this link: http://joule.ni.com/nidu/cds/view/p/id/2037/lang/en

    When I run it, the program communicates with the notification server and then tells me that "no software will be installed or deleted", giving me only the options to go back or cancel. From what I've seen, this message indicates that the software in question is already installed on the machine, but it is not. I tried this with the 11.0.0.1 and 11.0.0.2 update installation files. I used a test version 12 for awhile, but my license does not support and the trial period has expired. I already tried a complete uninstall and reinstallation of version 10 using the installation image, but the update always gives the same message. If anyone else has experienced this? Thank you.

    Hi James,

    The link you posted is not a complete installation, which is an update.

    You can find the full download from here:

    FTP://FTP.NI.com/evaluation/Circuit_Design_Suite/11.0/

    If you bought V10 and V11, we published within the period of SSP, you must download education 11.0 or Pro.  If you said that you renewed the contract of SSP, then you should download 11.0.1.

    I work with a third-party provider that adds agricultural markets that will update every 10 minutes on my site of muse. I'm a designer by trade, and they are the html code. They have problems with my original design elements being pushed around when they add the js include. They recommend at this time that I use another program like Wordpress, but I won't do that, because a large part of the site is designed and just add the markets. Here is the link to the site. At this point, the home page is the question. I can also provide a screen shot of how markets are supposed to look like

    This part does not seem too difficult.

    I bet they are now trying to "knit" their share of data right in your Muse- generated page, and they tell you that your code is terrible (and their smells like daisies). The usual clash...

    But it might be easier for you (and many others) if they offer their content as a separate page of small, so you can incorporate it as an iframe tag in an HTML object in Muse. No matter what code for permission to host the iframe, could be inserted as a simple script in Panel of Options of Page of Muse.

  • Problem of earthing GPIB-USB-HS connecting to a laptop?

    Hello

    The installation guide for the GPIB-USB-HS asks to "ensure that the computer and the GPIB devices are at the same potential on the ground."  I was wondering if there could be problems with the connection of portable computers (because they float)?

    What should / could happen if the computer was at a different potential on the ground?  A short circuit?

    Where the potential of the Earth is different, the installation guide also mentions to use isolated a GPIB bus isolator/Expander or a USB hub.  I guess that laptop USB ports are "isolated" and so should be good.  Is this true?

    Thank you!

    Meister,

    Because your laptop is "floating" it's referance (mass to the chassis) has nothing to do with your referance of material (Earth) unless you take measures to link the laptop chassis to earth potential.  Attach a GPIB cable to your laptop and your equipment will provide a way to fulfil the potential difference between your laptop and chassis of the Earth through the GND signal on the Gbspecifications FOR bus.  The GPIB bus is not intended to carry large currents (great potential of discharge) and you can force entry on the laptop protection circuits or equipment when you connect the GPIB cable.  Its kind of like touching a doorknob one day dry after you walk on the carpet of wool - you will get a 'static' shock when make you initial contact.  Do it at your equipment and laptop often enough and you will damage them.

    A worst case is when the chassis of the laptop is linked to a different potential that the grounded equipment (usually due to strengthening of wiring errors).  In this case there must be a current constant circulating in the commonly known GBIP GND signal ground loop.  Noise and / or damage will be celebrated according to potintial unlike.

    The cure is ALWAYS connect the chassis of the laptop on the chassis of the equipment by an external wire before connecting the GPIB Bus.

    I hope that clarifies the reasoning of 'Warning' that you see in the installation guide.  Kudos to you for reading your guide and to pay attention to the warnings!  Never be afraid to ask when you don't understand warnings

  • Problem of Simulation collector design & control

    I try to work on a collector in the simulation loop control & design but I found that there is a problem

    1. the data that I collect takes horizontal form, how to change the data of horizontal to vertical?

    2. the data that I collect does not move to the actual speed, has collected data in the wrong thread? Please correct me if I got hurt.

    Thank you very much

    For the rotation of the table, you must use the function "Convert 2D table" to the title of programming > table Palette.

    For the second question, I don't know what you're saying. What do you mean when you say "don't move to the actual speed? Do not control? Narrowly on measurement error? Delay?

    Think it is important to check to see if you have the engine as "Runga Kutta 1 (RK1)" since you are trying to control the real system.

  • Problem with the Code/Design view buttons

    (My bad... maybe a clearer title will help you...)

    OK, I work with DW CS4 v.10.0 Build 4117 on a platform of Win XP Pro SP3.

    When you work with files from my site, they open in Code view.  The Split and design buttons are grayed out.  When I click the page layout button, the check mark is sometimes next to the option Code, but sometimes next to Design (even if the page is clearly displayed only in Code view!).

    To view the file in Design view or split view, click the page setup button, click on the Code, click on the button layout again, click Design or split view and then it will display the page in this way file.

    It's SO frustrating!  Is this a bug in CS4?  (I scanned through the other topics and can't seem to find anything about it.)  I don't remember having this problem with CS3 and have spoken with other DW CS3 users who also say that they have never had this happen.

    What can I do?

    Thanks in advance for any help you can provide.

    Hi Susan,.

    I might have a solution for this one. I had the same problem. It would be 'reliable' whenever I would create a new PHP file.

    "File" > "New" > "PHP" > Layout 'None' > 'Create' - no buttons 'Split' or 'Design' (grey)

    In 'preferences' under 'File Types/errors', there is a section "open in code view".

    I removed the. The extension PHP from here, tried again and it worked!

    Maybe it will work for you.

    Good luck

  • same circuit design-different versions of multisim now fixed

    again the circuit model 74LS244N, now the pattern16t file works in different versions of multisim.

    How do you pattern16t signs might be useful.

    This circuit is interfaced with gpib, scsi, usb computer interface circuits.

    It's everything. software must always be carried out for each computer.

    Basically, there are computers with a different interface.

    Hello

    The application seems interesting to interface with instruments or devices with these buses. Of course, it must take into account the fact that there are off-the-shelf products that come with the drivers, etc.

    Also, I really liked how you have organized the scheme in Multisim with bus, etc.

  • Problem with routing/circuits between SG300-10 and Dell Powerconnect 5224

    Hello

    I just bought a SG300-10 switch and loaded new firmware 1.27 on it.  Configure my VLAN and trunks, but I have a weird problem that I can't seem to understand.  It may be something small, I'm missing, but no matter, I have been scratching at it all day and I kicked in the butt.  If anyone can point me in the right direction or maybe something that someone see in my config which is wrong, I can get the terminology/theory wrong, after all, I just spent my CCNA :)

    My configuration:

    I have the SG300-10 as my switch and changed over to L3, so it may be my core of my small network.  On port 1, vlan 200 is configured as my unidentified native PVID and I put it to 210(LAN network) to trunk VLANs, 220 (management vlan) on the tag to the Dell powerconnect 5224 24port switch.  On port 1 of the Dell switch, I install as a trunk it as well with the same configuration (vlan native of PVID unidentified 200, 210 and 220 tag trunking).

    I have installed virtual interfaces on the SG300 for each VLAN (vlan 210 = 192.168.210.1/24, vlan 220 = 192.168.220.1/24) and on the Dell, since this is a feature of L2, I changed the vlan 1 to 220 management and assign the IP 192.168.220.2/24.

    Now, since the SG300 web interface, I ping IP management Dell (192.168.220.2/24)successfully and vice versa, can ping from Dell web interface to one of the IP of the bridge VLAN (210.1 & 220.1) successfully so that test, to me, looks like the Dell communicates with the SG300.)  I also have the default gateway of the Dell 192.168.220.1 printer value.

    Server IP: 192.168.220.10/24

    Workstation IP: 192.168.210.80/24

    Now the dilemma:

    I have a server plugged into switch port Dell 2 (configured as 'hybrid' because there is no option to access, value 220 PVID, vlan, worth 220 Untagged) and from the server, I can ping IP management dell very well switch and can ping the IP of the gateway of great SG300 so.  On the SG300 switch, on port 2, I plugged in a workstation (configuration is in access mode, vlan 210 unidentified) who can not ping the server plugged into the dell switch.  The workstation, I can ping all the SG300 interfaces and also the IP management dell but I can't ping the server.

    Any ideas anyone can provide is much appreciated!

    Edition of VLAN.

    Lenell, thank you for the call tonight. It seems that we have found the problem. The SIN, although it is configured with a default gateway, the gateway that brings 0.0.0.0. We also checked the NAS works from the same subnet to connect but fails outside of the subnet. Conversely, we checked 2 computers have no problem to connect through the VLAN level 3.

    I hope we got the right direction.

  • Problems uninstalling Adobe CS6 Design Standard

    Hello

    I recently had to backup and wipe my mac and then transfer everything on it, which has now caused problems trying to open one of my apps of adobe cs6.

    Whenever I try to open them it says that I have to uninstall and reinstall applications (error 16).

    However, when I tried to uninstall CS6 it says I have that alias cannot open the original alias is found, with the options to remove or fix the alias.
    I don't really know what is the alias or how to fix it?

    Thank you

    Two possible problems:

    (1) you cannot install software CS6 by copying a backup or migrate it. It must be installed by an original installer. If you do not have your installer that you can download here:

    CS6

    (2) CS6 in incompatible with El Capitan if you don't have the latest version of the Mac OS X software. You will need to use an earlier operating system.
