PXI4065

You can use a PXI4065 to measure pulse?  15 volts to 10 milliseconds.

This is my requirement... "the output voltage MUST be at least 10 millisecs > 15 volts.."  There was something that I found in DAQmx which allows to get an array of values using the DMM, but I can understand where you set the sampling frequency.  And I do not know what are the parameters to use to determine the frequency of sampling?... for an impulse?

Thank you

Hi clint100,

Maggie has been only recommend that you use a numeric entry instead of an analog input, if you are able to mitigate your signal within the limits of digital input. The reason why we recommend this is because you will get a stable signal at 'high' and 'low' with specific hysteresis stable signals integrated in data acquisition. In this way, you won't see any noise on the signal and it seems to be a perfect square wave. You are quite capable of measuring a DC signal with an entry, analog, but it would be subject to noise and you wouldn't see a perfect 'front' as you would with an analog signal. Your DMM will taste the signal as an analog signal, and you'll see a decent square wave (with little noise and front down since it samples slowly and slightly rising slope). You can use the analog input where you can see more noise, but a less sloping edge fronts and, since he can taste much more quickly. You will need to do a division of tension, however. With a division of tension and a digital input signal, you will get a clean square pulse. It is to you what you would want to do.

Best,

  • SMU, used for the measurement of current

    Hello

    I need to measure current in the range 5 to exit 10uA by a current source PIN. I would have usually connected PXI4065 on this PIN and measured current. But in this case the current to be measured is low.

    I have EMS 4130, which has high accuracy of current measurement to 200mA range (0.03%+0.02)uA.

    Can I use the current part of the EMS (CH1) measurement to measure current? What should I activate CV outputs (Hi = 0V) who appears in the soft front panel?

    Or just without activating the outputs I can measure the current sink. The program of flexible panel displays current measurements, but I don't know if the EMS can be used like that.

    Thank you

    Not sure NI SMEs, as I have not had the chance to use it yet.  SMU of Agilent could be used this way, so I guess with OR as well.  You must use out SMU in constant voltage source / I measure mode.  Would you say the SMU to hold the voltage at 0V, and allow current to the sink (or source) as necessary to maintain this 0V output.
