PXI-6704, parallel to the measurement of the resistance

Hello

I'm in show two separate circuit analysis procedures. First of all I would like to provide two pins with current and measure the response of circuit elsewhere, and second, I want to test the total resistance not fueled between those two pins. If I have a current PXI-6704 output wired to the pair of pins and the value 0 output amp, it will interfere with the measure of resistance to these pins (as a parallel resistance) or if it excludes all signals and appear as an open circuit?

I can use the PXI switch to connect and disconnect the DMM to measure, but test specifications require no supply current through the switch.

I don't have the equipment to hand, I know it would be the fastest test. We design the test set-up circuit in parallel with the PXI test chassis.

Thank you

Mello

Hey Mello,

Thus, the output impedance of your card is 1GOhm, so unless what you measure is huge, so it should appear as an open circuit. I hope this helps!

  • Measure the resistance with PXI DMM 4072 on different frequencies

    Hi all

    I tried to get on board various and unable to find solutions for that. I'm trying to measure resistance using NI PXI-4072 on frequencey 1 kHz, but not luck. When I try to use Agilent LCR meter I see the correct value of the resistance.

    I've seen a few posts on this but don't have no satisfactory solutions.

    In above post, someone said that I can use 4072 DMM OR digitizer, does not have a lot.

    Can someone please provide the right path for me to solve this problem.

    Thank you

    Hello Puneet_K,

    I checked the data sheet and the method of measurement described in the specifications of the NI 4070/4072 http://www.ni.com/pdf/manuals/371304g.pdf; indicates that the ability is measured using an alternating signal and select the test frequency range, for example 3 kHz, 1kH or 91 Hz. The resistance is simply measured using a DC signal, and it is often sufficient to measure the internal resistance of a battery. If you need a more flexible control for the measurement, you probably get a card like the function generator and then set a multimeter to measure the voltage and another DMM to measure the current and calculate the impedance of these values.

    I hope this helps!

  • How can I change the configuration for the output channels analog on a PXI-6704?

    I can't seem to understand how to access the configuration of the channels to the outputs analog (channel 33 and 35) for PXI-6704.

    This piece of test equipment is out of tolerance and must be calibrated.

    I have followed the procedure of calibration http://www.ni.com/pdf/manuals/374081b.pdf, but am getting hung up on step 8, where it is said to repeat steps 4-7 when changing the _cal_ao_current_offset. I can't figure out how to open this channel because it is not listed as a physical channel for step 5.

    I'm using Labview 7.1

    Thank you

    Hello! What you need to do is to add 'Internal channels' to your list of channels, so you can choose the _cal_ao_current_offset or _cal_ao_voltage_offset.  This is done through the drop-down list channel right click and select "I/o name of screening...". ».  There will be a check box that says 'Internal channels' and will provide you with all available internal channels to enter your vi Create Channel.  I have attached some photos illustrating how to do. See you soon!

  • How can I use 2530 b and 4065 to measure the resistance between two selected pins?

    I want to be able to select 2 corners on a test with 2530 b set-up and measure the resistance between them with a 4065 DMM (PXI all). Ankles in question are each in blocks of 32 different poles, so I can match them in a double configuration 32 x 1 four or 64 x 1 if necessary. I can measure the resistance between several different pine sets as 0 on 33 pine pine, pin 0 at pin 34 pin 0 to 35 pin and pin 1 to 34 pin, pin 1 pin 36, etc.

    I understand how to measure resistance between a given pin and Earth using the the 2530 4065/b using the wizard OR-DMM/Switch Express, but it is unclear if I can measure the resistance between the two pins of selected by different user. I am a newbie of labview, used to write things in c#, so it may be something very trivial (I hope).

    Any ideas?

    Thank you

    Hey Russ,.

    I recommend starting with the following example (located in the Finder the example ('Help' to find examples):)
    "" Material input and output"Modular Instruments ' OR-Switch" niSwitch Dmm Switch Handshaking.vi

    Because you use a scan list, you can simply drag the two connections to the same entry and then the switch will wait for the two to settle before you send a trigger of the DMM... problem solved.  For example, to connect the CH1 to Com0 (DMM +) and CH93 to Com4 (DMM), then take a measure, then connect CH38 and CH120 to the DMM, you would use the entry list of scan to the following address:

    CH1-> com0 & ch93-> com4; CH38-> com0 & ch120-> com4;

    Note You can have as an entry in list of switch module scan.  In addition, you can only have a single advanced analysis and a measure full per switch module.

  • PXI-2530 defies the laws of physics trying to quantify the resistance of the pairs of specific relay relay.

    I have a problem with a PXI-2530 switch card work in matrix mode 4 X 32. I need to determine the resistance of the pairs of specific relay within the matrix. I have a PXI-4130 and a PXI-4071 in the same chassis, so I take measures 4-wire in a configuration like this...

    Resistance symbols represent relays in the switch. Here is a representation of matrix-style switch routes I use. (This should look more like the interface of soft face before switch)

    The two diagrams represent so how I take my measure. I shorted outwardly columns C8 & C9 (shown in the first graph), I am sourcing 500 microamps of current and toggling the current source for a positive and a negative measure, I am able the voltage with the DMM. For the above measure I'm mesure.2619 ohms. This should be of course my resistance of the relay K8, K41, as well as Terminal block and wiring.

    Here's another schema. This should measure the resistance of two same...

    All I have changed is routing between the meter from the source. Here's the view from the matrix...

    With this measure I'm mesure.0873 ohms. I can have the same resistance as the first example except getting a very different measure.

    It gets even more interesting. If I had to take 4 pairs of wires, I use here, there are 16 possible configurations. I took each of these measures, and half of them gave me environ.25 ohms while the other half gave me environ.09 ohms. I tried this on a 2nd chassis and got the same result. My data are in the attached sheet. (My examples above are rows 1 & 5.)

    Taking the measure of how we are, all these measures should be substantially the same. I have a current source constant, (I even tried a crimp in instead of the 4130 and got the same result.) and the meter is high impedance.    If I had a pattern for the PXI-2530, I could do a little more analysis to know why I get various measures. Is there some diodes clamp on the lines or columns in the matrix? Something external must act solange this circuit. If I can find out what that is, I could determine my resistance to relay to a quantifiable level of uncertainty.

    Any help would be greatly appreciated.

  • possible to start the MXI-3/PXI system after booting the PC?

    Hello

    I'm new here, so I just asked this question in another thread with a response. I did not notice that it was already marked as solved, so I'll ask again in my own thread.

    My problem sounds very akin to that of Kobi, but there are a few differences that hold my hopes up that the problem could be solved. Summary of the configuration of the system:

    -PC (MXI-3)

    -> PXI1002 (Chassis1)

    -> PXI8335 (port1 - in)

    -> PXI8335 (port2 - out)

    -> PXI5122 (measure)

    -> PXI1002 (Chassis2)

    -> PXI8335 (port1 - in)

    -> PXI5122 (measure)

    The goal is, as it is easy to guess, to be able to start at any time, additional measuring devices even when the pc is already running.

    The situation is different from ' Kobis in a precise point: in my case the cards and all equipment is permanently visible in MAX, even if I started after the pc has started. This change is the boss of the leds, and PXI cards do not pass the test in MAX. The following screenshot shows the configuration of the system how it is observed after the two ways to start the full system (first first pc or PXI).

    (Even if I use a German version of labview English my MAX partially keep, I hope this isn't a problem.)

    I have tried to identify the PXI system and chassis, but failed to get a different result. The NIscope screws are ordered initialization and reset of all sessions, but only if I turn first PXI systems.

    So you think it would be possible to achieve the goal of implementation, or should I stick to the start-up of the pc after turning on the PXIs? I did some research and I know, the installation guides to specify the order to turn on the devices, but I thought that it was only intended for installation/first round.

    I would be really grateful for any advice in the present.

First install the driver (in your case the NO-Sync) on your PC, then install it on your system remotely through MAX.

  • For streams_pool_size fine adjustment, the parallelism increases the number of integrated process replicat?

    The GoldenGate tuning white paper (http://www.oracle.com/technetwork/database/availability/maa-gg-performance-1969630.pdf) recommended setting based on the integrated replicat process number streams_pool_size.  It says nothing about parallelism, as it does for integrated capture.  If I configure the 4 replicates, use this number in the calculation?  Alternatively, because I want to implement parallelism to 16 for each replicate, I have to use 64 in the calculation?  The latter would make the recommended streams_pool_size 80 GB.

    The calculation you are looking for is:

    (max_sga_size * parallelism) * 25%

    In this example:

    (1024 M * 2) * 25% = 2560M (2.5.G)

    Your streams_pool_size must not exceed 3.5 G no matter the amount of parallelism.

    Do not confuse the parallelism of the database with goldengate parallelism. Goldengate parallelism is defined using the DBOPTIONS INTEGRATEDPAPRAMS options.  If you want you can refer to my presentation to transform the integrated process of goldengate to my slideshare.net (replication extreme at IOUG collaborate 15) site

    If using a Mac computer, go on--> Utilities application--> Adobe installer--> former names of applications and run the uninstaller for legacy applications.

    If you use a Windows PC, go to control panel of-->> program and features and uninstall the old applications.

    It allows to uninstall everything related to legacy applications, but your setting should be imporated to the new version of the applications.

  • degree of parallelism and the number of files in the tablespace

    Hello

    I'm trying to find the relationship between the number of files in a tablespace and the degree of parallelism. because of the number of files in a tablespace effect dop in parallel query. because if several files are in the tablespace/o of the system has increased and the system became more feverable for a query parallel.

    But I looked in the dop formulas I can't find any settings that specify how the file is there in a tablespace. Please give me the formula for calculting dop in oracle.


    concerning
    Nick

    Hi Nick,

    It is not easy to determine the optimum degree of parallelism for the tasks of the Oracle.

    Oracle says that the best degree of parallelism for a query is based on several factors. These factors are presented in order of importance:

    -The number of processors on the server.

    -The number of physical disks located in the tables.

    -For parallelization of the partition, the number of partitions that will be available, based on the size of partition (if any).

    I can't find any settings that specify how the file is there in a tablespace.

    This is the number of physical spindles that matters, is not at the level of the tablespace.

    If I have diploma = 8, cpu_count = 8 and data are on 8 discs, there is no pretense.

    It's one of the problems with big great drives today, too few concurrency...

    I hope this helps...

  • Can I use differential ground with PXI-6704?


    The answer is no.

    I spent most of the day on the phone with engineers of NOR. The PXI-6704 manual provides conflicting information. Indeed, the PXI-6704 that she "can connect to a load that has a floating ground" operator, but it should also be mentioned that the load will no longer a floating ground, because the planes on the ground of the device are connected to the signal ground of the computer, which is connected to the Earth System. I don't know why the verbiage on floating to the ground is included because there is no way to isolate the load with this device.

    Our team regained the PXI devices OR. We have worked with the Application engineer spoke to R & D of clarification in the manual.
