• How can I use internal clock case OR USB - 6259 BNC for the acquisition of digital data in my own big software?

  I want to integrate the ANSI C sample program ReadDigPort - ExtClk.c in my own big package.

  I want to use the internal clock of the BNC NI USB-6259 (.. 80 kHz 120 kHz).

  In the document:
  High speed M: Series Multifunction DAQ for USB - 16-bit, up to 1.25 MECH built-in BNC connectivity. / s,.
  is written:
  Or sample DI source clock: Any PFI, RTSI, HAVE sample or convert clock, AO, Ctr n out internal and many other signals sample clock
  The digital subsystem doesn't have its own dedicated internal synchronization engine. Therefore, a sample clock must be provided another subsystem on the device or from an external source.

  How can I use internal clock case OR USB - 6259 BNC for the acquisition of digital data in my own big software?
  With what other subsystem on the device can generate a source of the clock? How?

  It is possible to set a clock on an internal counter (for example ' Dev1/ctr0"):
  Creates channels to generate digital impulses that define the freq and dutyCycle and adds the channel of the task that you specify with taskHandle.
  DAQmxCreateCOPulseChanFreq (taskHandle, "Dev1/ctr0" units, clockName, idleState,
  initialDelay, freq, the duty cycle); works

  But it is not possible to drive this internal clock to a terminal (for example "/ PFI0/Dev1"):
  DAQmxErrChk (DAQmxCreateCOPulseChanFreq (taskHandle, "/ PFI0/Dev1", clockName, units, idleState, '))
  initialDelay, freq, the duty cycle); does not work: error DAQmx: measurements: type I/O of the physical channel does not match the type of I/O required for the virtual channel you create. Name of the physical channel: PFI0. Name of the virtual channel: clock

  The sample clock source can be derived from an external terminal (for example "/ PFI0/Dev1"):
  Sets the source of the sample clock, the sample clock rate and the number of samples to acquire or generate.
  DAQmxCfgSampClkTiming (taskHandle, "/ PFI0/Dev1", maximumExpectedSamplingRate, DAQmx_Val_Rising, ")
  DAQmx_Val_ContSamps, bufferSize); works. Acquire or generate samples until you stop the task

  But it is not possible to derive the internal counter of the clock (for example ' Dev1/ctr0"):
  DAQmxCfgSampClkTiming (taskHandle, "Dev1/ctr0", maximumExpectedSamplingRate, DAQmx_Val_Rising,
  DAQmx_Val_ContSamps, bufferSize); does not work. Error: Acquire or generate samples until you stop the task: make sure that the name of the terminal is valid for the specified device. See Measurement & Automation explore valid names of terminals. Property: Property of DAQmx_SampClk_Src: DAQmx_SampClk_ActiveEdgeSource device: Terminal Source Dev1: Dev1/ctr0

  Hi datafriend,

  using what it says is correct:

  Or sample DI source clock: Any PFI, RTSI, HAVE sample or convert clock, AO, Ctr n out internal and many other signals sample clock
  The digital subsystem doesn't have its own dedicated internal synchronization engine. Therefore, a sample clock must be provided another subsystem on the device or from an external source.

  This means that if you do not use an external signal as clock you can use the sample clock to HAVE it on board or at the output of the internal counter.

  There are also 2 ANSI C examples in this regard:

  http://zone.NI.com/DevZone/CDA/EPD/p/ID/4485

  http://zone.NI.com/DevZone/CDA/EPD/p/ID/4488

  So in both cases you have to use a fictitious task you need only for the generation of the internal clock (HAVE or CTR)

• Want a ramp of output voltage over time and measure input 2 analog USB-6008

  Hello

  I want to produce an analog voltage output signal that increases over time with a certain slope, which I'll send in a potentiostat and at the same time I want to read voltage and current (both are represented by a voltage signal) that I want to open a session and ultimately draw from each other. To do this, I have a DAQ USB-6008 system at my disposal.

  Creation of the analogue output with a linear ramp signal I was possible using a while loop and a delay time (see attachment). Important here is that I can put the slope of the linear ramp (for example, 10mV/s) and size level to make a smooth inclement. However when I want to measure an analog input signal he's going poorly.

  To reduce noise from the influences I want for example to measure 10 values for example within 0.1 second and he averaged (this gives reading should be equal or faster then the wrong caused by the slope and the linear ramp step size.) Example: a slope of 10 mV/s is set with a 10 step size. Each 0.1 s analog output signal amounts to 1 mV. Then I want to read the analog input in this 0.1 s 10 values)

  Because I use a timer to create the linear ramp and the analog input is in the same loop, the delay time also affects the analog input and I get an error every time. Separately, in different VI-programs (analog input and output) they work fine but not combined. I searched this forum to find a way to create the ramp in a different way, but because I'm not an experienced labview user I can't find another way.

  To book it now a bit more complicated I said I want to measure 2 input analog (one for the voltage of the potentiostat) signals and one for the current (also represented by a voltage signal) and they should be measured more quickly then the bad of the analog signal. I have not yet started with because I couldn't read on channel work.

  I hope someone can help me with this problem

  An array of index. You want to index the columns for a single channel.

• How stable is the long term outputs analog USB-6008?

  The USB-6008 datasheet do not specify the stability long term of the analog inputs and outputs.

  I'm looking for stability compared to the ambient temperature and time (several months to a year), mainly for the outputs or the D/A reference voltage.

  Is there any information available?

  Thank you.

  The precision specification takes into account the evolution both because of the temperature and duration (stable).  Thus, for the period of a year that we guarantee these specifications, which list you is correct.  However, apart from the period of one year since the calibration, this specification may be is more inaccurate.

I have a Macbook with charger W 29, I was wondering if I can also use this charger with a USB C to the lightning cable to charge my iPhone 6 Plus, with no risk of damage to the battery of the iPhone. Is there guidance from Apple or not experience from other users?

  If it sends not more then 5volts to the device it cannot harm him.

• DAQ USB-6008 will be able to power and record voltage for UMS T5 blood pressure at the same time?

  I would use my NI USB-6008 to power my blood pressure monitor UMS T5 (http://www.ums-muc.de/en/products/tensiometer/t5.html) but also to take readings of it, but I don't know if it's possible to do it properly. The power supply for the instrument can be as low as 5V, I can easily get the dedicated + 5V channel. I'm able to feed the instrument and connect it to an analog input on the 6008 and measure a voltage in differential mode. However, when you read the documentation of support for the instrument, I find the following:

  "Potential pitfalls of data acquisition: the pressure transducer is configured in a full Wheatstone bridge, the input voltage and mV signal output can be connected to the same reference (mass)." Therefore, the mV output signal can be measured using a differential voltage measurement. Therefore, do not make an asymmetric measure of pressure transducer mV output. "(http://www.decagon.com/assets/Uploads/MeasuringUMSTensiometerswithnon-UMSControlandDataAcquisitionSystems.pdf)

  My understanding is that the 6008 can take a differential measure if I attach the signal '+' and the signal "-" to the analog inputs of positive and negative terminals. However, it seems that all the ports of ground on the 6008 are grounded to the same reference, which would make my measure of invalid tension according to the above paragraph. So my real question is: if I try to record the voltage with one of the analog inputs on the 6008 in this way, is the valid measurement? Or I need to find a separate power supply, with a different reference field to ensure that the measure is accurate?

  The technical details of this device is very poor. The manual is not much better. Companies that want to sell scientific equipment should publish decent cards or get out of business.

  In section 3.4.3 General requirements the device is described as a "bridge not amplified circuit.  This information along with the impedance of the bridge should be in the specifications, because it is essential to apply the device under any circumstances other than the nominal behavior in 10.6 V.

  The answer to your question is:

  You can use it with the box USB-6008.  The 5 V supply will result in output voltages a little less than half (5/10.6) the voltage specified in nominal conditions. You can use the differential input mode on the box USB-6008.  The absolute input voltages will be approximately 2.5 V with the 5 V power supply. This voltage is in the range of the aircraft. The differences are likely to be less than 100 mV. The resolution of the USB-6008 on the + /-1 V is located about 0.5 mV so your resolution of pressure will be about 1% of full scale. The voltage input impedance and termination of the USB-6008 will present a few errors.  These can be in the order of 5 to 10%. I can't predict much better without the missing bridge impedance specification.  These errors should be relatively constant and systematic. A calibration of the whole system - sensor and together hardware DAQ should allow you to compensate for a large part of this error.

• NEITHER USB 6008 tension problem reading

  Hello

  I am trying to program a USB-6008 on a mac. When I connect to the input to analog 5V output I get a reading of 3.67volts, while on an osscilascope, I read a 5volts voltage. Is this normal? Need to load resistors? Also, I get the same effect with the release of tensions for the analog output.

  Hi Zepp2,

  Thanks for your post. The pins are you connect together on your device? Depending on the type of connection you have the wiring may not be quite right.

  I found a few documents online which hopefully should help you:

• No output from USB 6008

  Hello

  I have connected a USB-6008 to my computer, but can not read all the output using a multimeter when I run my program.

  I went in the measurement and automation explorer, disappeared to the USB6008 device, click on test panels and selected the output voltage. From there, I gave different output voltages and I read all this tension using a multimeter to the USB-6008.

  To check if there is something wrong with the pattern-block etc that I install, I connected the 6008 to another computer that is running labview and used the same program. It gives a very good result.

  Does anyone have any suggestions as to what can go wrong on the first computer?

  Much appreciated,

  Paul

  If I were in your shoes I download DAQ - mx 8.6.1 (here) on the PC that you are having problems with and give it a go.  I don't know why the 6008 would work on a PC and not the other when they have the same configuration.  Do you have other devices working on the troubled PC?

• Cannot read the digital channels as physical on USB 6008

• OR USB-6008 control

  Hello

  I am currently using a map of measurement computing USB - DAQ 3101, but now uses a card DAQ NI USB-6008 and need a bit of help with conversions of connector and pinout.  MC USB-3101 has a pinout 56, where, as the NI USB-6008 housing has a pinout 32.  I've done the research, but found different results.  Someone at - it a concrete conversion pdf or Web site for these conversions?

  Thank you

  Hello Steve,.

  Thank you for your email back! I now see what you were asking. The VOUT1 and the VIOUT2 I feel would be the equivalent of the 6008 AO 0 1 AO and GND. So pines 14-16 These would be the pins that you would use to produce a voltage based on the specifications of the card. It is not a "NC" or not connects to the 6008, as all the pins are used.  Let me know if it helps! Have a great day!

  See you soon!

• I can read two-channel USB-6008 using THE Signal Express?

  Hello world!!

  Is possible to read the two analog inputs at the same time?

  Example: Using Signal Express, I need to read the (channel 0) analog input and analog input (channel 1) at the same time.

  I try this but, the signal on purpose gives me an error message saying that I can't read several channels at the same time using the USB-6008.

  Is this true?

  Thank you
