Hello, Support for the USB-3101 device was added in release R2009b but support was NOT added for the USB-3101FS. At this time, the USB-3101FS is not supported by MATLAB.

No, it does not. But if you'd like you can use mathscript in Labview to control the DAQ card.

Hello Dave, Thank you for your inquiry. Currently the USB-3101FS is not supported by MATLAB and there are no plans at this time to have support added.

The USB-3102 is a slow device, meant for occasional/DC writes, not waveform creation. For Waveform creation, consider the USB-3101FS. When using AOutScan with the USB-3102, you can only send 1 sample per channel, as you are doing. Your data array must be ushort, and are effectively in the units of “raw D/A counts”. i.e. values from 0 to 65535 for a 16 bit D/A converter. You can run the C# example named ULAO02, and it will demonstrate this for you.

All models of the USB-3100 series (except the USB-3101FS) do not have the capability of streaming hardware paced analog output values. They can only output software paced values. Meaning one new value per channel on demand. When used with AOutScan(), the number of points must be equal to the number of channels you are currently using. For example, if you set up the scan for 4 channels, then you must set it for 4 points. The benefit of this is to set all 4 channels with new values simultaneously, but just one point per channel. To be able to stream out waveforms at a uniform, consistent rate (hardware paced), you would need to use a device such as the USB-3101FS. This device can stream data out up to 100K samples per second aggregate or per channel when SIMULTANEOUS option set in AOutScan().

The USB-3102 has no analog input (AI) channels. So AIn and AInScan cannot be used. Its primary purpose is analog output (AO). Also the USB-3102’s AO capability is very slow (we spec 100 updates per second, divided by the number of AO channels used). It cannot generate waveforms. If you need both AI and AO, consider the USB-1608GX-2AO. It supports AI waveform in and AO waveform out concurrently.

No, the USB-3102/3104/3106 Series of analog output DAQ devices do not source current. It does not provide the power for your circuit. You must be wired to a sinking input with a loop power supply in the circuit.

Yes, multiple current control (output) channels on the USB-3102 can be ganged up in parallel to control additional current. For example, two channels in parallel can control 0 to 40 mA.

Hello Venu, Our USB-3103 analog output DAQ device supports (8) 16 bit analog output channels, (8) programmable digital I/O bits, and (1) 32 bit event counter. You can review the specifications here: http://www.mccdaq.com/usb-data-acquisition/USB-3103.aspx Please contact our distributor in your area for pricing and delivery. You can find all of our International distributors listed here: http://www.mccdaq.com/contact2.aspx

Hello Venu, The USB-3101 and for that matter any one of the products in the USB-3100 series with the exception of our USB-3101FS will not be capable of outputting a 5khz Squarewave. The reason is that these DAQ devices are software updated so they are dependent on the PC and the operating system (Windows). You will need to use our USB-3101FS or one of our multifunction DAQ devices that support hardware updated analog outputs. Here you will find details on what products support analog output data streaming and an example program to get you started. http://10.17.5.111/KnowledgebaseArticle50383.aspx?Keywords=USB-3101

Hello Khalid - After installing ULx, try one of the examples that it installs, named: ULx Gen Mult Voltage Updates-SW Timed.vi You will need to lower the default rate since the USB-3104 is a rather slow board. Also, we have a somewhat simpler example posted on our knowledgebase at: http://kb.mccdaq.com/KnowledgebaseArticle50395.aspx

As you pointed out, we do not offer a DIN rail mount for the USB-3100 Series of 4/8/16 channel devices. While MCC does not offer any other form factor for analog output devices, our sister company, Data Translation does do so for their 4 and 8 channel models DT9853 / DT9854. However note that the USB-3105 you asked about has 16 channels.

Hello Vinay - Thank you for your inquiry. The USB-3105 cannot sustain a full scale output of +- 10 volts at 10 mA. The supported current range is +- 3.5 mA. We do offer a “High Drive” unit called the USB-3114 that supports up to 40 mA per channel with a max current output of 180mA aggregate. You can review the specifications for the USB-3114 here: http://www.mccdaq.com/usb-data-acquisition/USB-3114.aspx

The USB-3106 can be configured to output a fixed voltage with a max output current rating of +- 3.5 mA or it can be configured to output a 0-20 mA signal. If you need a high current drive unit, our USB-3114 can output a fixed voltage level with a max current output rating of +-40mA. Specification for the USB-3114 may be found at the following link; http://www.mccdaq.com/usb-data-acquisition/USB-3114.aspx
