This product is everything I need and more. Once it is set up, it works very smooth. This product is a very good buy. Thank you John. No differential mode. MC offers great value, great performance and quick delivery. Thank you. Use with Java is not possible. Was this answer helpful?
Can i get FFT graphs for modal analysis. You could obtain that yourself from a 3rd party, specific to your programming language C , VB, etc. Can I use the 5V output to power a small relay? Are there code examples in the Android UL to achieve this kind of operation? Thanks in advance for your help! The digital output bits are capable of driving up to 24 mA. We also have ready to run examples that can be downloaded from the Google Play. I am a bit confused with how the external pacer clock signal is used while acquiring 2 channels of data.
I am using a USB Using the onboard clock at 50kHz my signals looks fine. Repeating that with an external 50kHz clock, I seem to be sampling at the wrong speed. Is there more to the external clock than a simple swap?
I ultimately need to synch to external rotating equipment, hence the use of the external clock to stay in angular synch with a shaft. A pressure sensor or transducer typically converts pressure into an analog voltage signal. I have 8 analog signals generated from current and voltage sensors with range 2. Normally, I am have used current and voltage probes directly to monitor these currents and voltages on oscilloscope Not from sensors. Then I used the FFT property of oscilloscope.
Currently, I don't have these probes due to their cost. Can I collect the data from these sensors and then manipulate them to be used in FFT analysis? Note: My switching frequency is just 6kHz, so 24kHz sampling frequency is fair enough. All other signals current will require signal conditioning of some sort. Does connecting all these grounds to an external ground improve noise immunity?
Assuming all the Analog and Digital grounds are connected inside the device, don't I need to connect at least one of these to my common ground? For the purpose of better noise immunity each ground has its own plane but eventually come to a common point.
It is not recommended that you mix your ground connections. Connecting all your grounds together could cause ground loops which could introduce noise and signal error.
For detailed information on proper signal connections. Does the unit come with any free software besides the programming interfaces that I would use to develop my own data acquisition package? Hello Charles - Yes, your order will include software other than the programming libraries that you're referring to.
The strip chart allows for logging up to 32K samples per channel per file. My mA transmitter requires a minimum voltage of Can USB supply this voltage to the transmitter or I need an external power supply for the transmitter? The USB is only capable of supplying a voltage source of 5 volt mA. You will need to provide an external excitation source for your transmitter. Can I use the counter to count pulses during a gated period.?
Hello BigRockr - Thank you for your inquiry. When I have a discussion about a counter gate I think of an input that allows you to control when the counter is enabled and when it is disabled. Unfortunately, there is no gate control for the USB counter. I'm currently using a digital multimeter with a 10 Mohm impedance load and 0. The minimum data-. Thank you for your inquiry. In order to read a current signal you would have to provide some signal conditioning to convert the current to a voltage.
Digital inputs must be polled via your software program there is no automatic state recognition by the USB hardware. Once your program decides the state has changed, then it could take action.
In summary, MCC does not offer software to perform this task. Hello, We have got a mccdaq usb card. We bought it for developing Android application. After trying we see there is no support for Android. Is there a firmware update or another solution for Android support of usb If not do you suggest any othe. I wish to buy this device to my company and to check if it can answer our needs. The USB supports 8 analog input channels with an aggregate sample rate of K.
However, when sampling the digital inputs by themselves or in combination with the analog inputs, the sample rate is reduced to Hz for all inputs.
