• acquire the voltage output of a channel of analog output current

  I'm controlling a HV configuration rather sensitive analog output voltages. Is there an easy way to read the voltage level which is currently awarded by an analog output?

  Hello

  If you set your subVIs different voltages, you can be sure that the voltage you set in these screws are similar to tensions, you have to your output PIN. For example, you could write the value you give to the output in a variable and read this variable in you main VI.

  Kind regards

• Digital output to a different voltage?

  Hi all

  I finally finished my program of data acquisition for the laboratory, which made the acquisition of AI voltage multi-channel digital outputs with timed to control the gas valves. My post-doc asked an additional feature, however, which must be able to have the analog output... It turns out that what he really wants to do with the feature is to have output digital, but with a different voltage value (he never hears on the sending of information higher or lower in a simple experiment).

  Now, the program is set up to run digital output now, it would be quite a bit of work to change in a zone of OCCUPATION. Is it possible to simply change the settings somewhere to have the ups to DO at a different voltage? I hope that this is the case from a card of 10 dollar Arduino can do 5V or 3, 3V.  Our DAQ card is the NI PCIe-6353. I looked through the data sheet and found nothing.

  Thank you.

  p.s. I suggested using additional circuits to set the tension for a given experiment. The post-doc said it was possible, but inconvinient. :/

  Well, it is just too bad for the post-doc.  Maybe he should give you better requirements next time

  OK without being in a bad mood, it is not a way to change the digital output voltage.  When you talk about DIO cards really aims to communicate only high or low and have a voltage. The only other option would be to use 4 AO ports on the card and treat them programmatically as DO.

• Effect of the variation of the intensity of the LEDS on the Photodiode output current

  Hello

  I just started today to use the multisim and want to analyze how the intensity of the LED (LED_ir in multisim) is performing the Photodiode (TEMD1000 in multisim) output current. How to adjust the intensity of the LED and check the corresponding output on the photodetector on the oscilloscope.

  I just built the attached LED design and don't know how to design the model for the foregoing analysis.

  Could someone help me with this.

  Thanks in advance.

  Hello

  Multisim works mainly with voltage and current, and whenever you need to represent the other phonominal naturual have a voltage or current source control.  For a TEMD100, you must connect to a source of voltage up to ternimal light represents the input light.

• the pci-6238 digital output current

  Hello, I referred to the NI 6238/6239 specifications, but I've not seen this specification.
  I wonder if the maximum output current is the same as the current (9mA) of entry?

• Controlled by the voltage analogue output

  I missed more or less in my attempts to use the analog output features DAQmx.  What I want to do is to create a program that will spend the next an analog input channel voltage analogue output channel.  The basic idea is this: I am able the differential voltage in a simple temperature detection circuit.  When tension crosses a threshold (for example, 2, 5V), analog output channel kicks on a constant 5V and stop to expel 5V when the tension of AI cross back on 2, 5V threshold.  Is it still possible? I had trouble finding examples or starters to tide me over.  Any suggestion would be appreciated. Write the code to acquire the signal of the AI is not a problem, I'm not sure of how to integrate the functionality of the ao.

  Thank you.

  Unfortunately I do not have libraries of Measurement Computing, so I really don't see what you're doing with your code, but I'll attach one VI example I did with DAQmx to get going you, and I hope that thinking in the right direction. I've added the analog out and digital output to show how each works. If you can make your code in DAQmx, please do and post and I can help you.

• Output 2 length of time different voltages while recording the current of one of the outputs

  I create a vi that generates output 2 waveforms of voltage different (AO1 and AO2). These signals is different in duration and number of times it will be produced. AO1 must take place several times while AO2 is running her first time. I also record the entry of AI1 output in AO1. I have attached a vi that I thought it would work. I thought it would be good to have the AI/StartTrigger initialize the acquisition and the output voltage. However, this arrangement results in an error. The error I get is-200802. Am I going about this all wrong? Any ideas?

  At first glance, I see some problems with your code:

  -You arecalling DAQmx writing before calling DAQmx Start. The departure must be called before writing.

  -You have two tasks of analog output. Only analog output task is allowed per unit. If both of your analog output channels are on the same card, they must be in the same spot.

  Here is a great resource for getting started with DAQmx programming.

• read the output of a path of analog output current voltage

  In DAQmx if you are unsure of the status of a digital output port, you can take a reading on this subject.  When I try this on an analog output, I get an error.  Is it possible to query the status of the output of an analog output?  I realize that I could follow the State with a variable, but a direct reading would be really handy.

  Hello, GIS.

  There is no way to read the output in the AO modules without wiring physically the signal to a module to HAVE.  You are able to use a variable to read the current value of the output, as you mentioned earlier.

  Channels AO multifunction boards, however, can be read through tasks of entry by rounting in-house channel to read ao vs aoground.

• Using the NI USB-6009 case to generate a 12VDC output and output current of 300mA

  Hello

  I use the OR-USB-6009 my power supply for a 12VDC with drive current of 300 solenoid my. Initially, I used a non reverse Op-amp circuit and Inverter circuit operational amplifier to get the + 12V and - 12V output but I could not get the current I required. Should I use a transistor?

  Please find attached photos. Any input would be appreciated.

  Thank you

  Adam

  Well, really depend on your piercing circuit.  But I used most systems use the transistor to set the voltage of the device to 0V.  So when your DIO is high, the output is actually 0V (low).  So using a converter chip, your release of the DIO will be sort of the output circuit.  If you get the right IC, then the inverter will give you also a few extra current to drive your transistor.

• PCI-6115 counter 0, 1 output current capability?

  Can charges of 50 ohm PCI-6115 player with the counter 0 or 1 meter outputs? The specification data sheet had no information on that.

  Try searching for "Advanced: incarceration strategy property attribute ' and ' voltage levels: data voltage range property" in aid of generator/analyzer of signals for the digital waveform installed with your driver. This should allow you to change the levels of tension on the fly. To use this attribute, you must have the latest driver HSDIO (2.0).

  Is that what you are looking for? It is an advanced attribute, and most of the use cases should not dictate it you have been warned. I hope this helps!
