2016年4月14日 · Now, considering your PXI-6704 is a static analog output, your sample rate is dependent on how quickly you can write samples to the DAQmx Write. On a Windows PC, I would not expect much faster than 1kHz. Even then, it will not be a consistant sample rate (software timing is horribly inaccurate).

2014年6月26日 · The PXI-6704 manual provides conflicting information. Indeed it informs the PXI-6704 operator that she "can connect to a load that has a floating ground," but it should also mention that the load will no longer have a floating ground, because the device ground planes are connected to the computer system's ground signal, which is connected to ...

2011年4月20日 · Scroll down to the NI 6704 and you will see which pins on the SCB-68 route to which channels on the PXI board. The SCB-68 works with a huge number of different cards and as such needs to be non-specific in terms of which pin goes where- so the pinout for the connector block changes depending on which card is connected

2016年1月22日 · I have a question regarding function generation, PWM to be specific, without the proper hardware. I am running NI PXIe-8135 Embedded controller in a NI PXIe-1078 Chassis. It is equiped with NI PXI3-8532 (DeviceNET), NI PXI-6515 Industrial Digital I/0, NI PXI-6225 (M Series Multifuction DAQ), and NI PXI-6704 (Analog Output).

2005年7月7日 · There are lots of examples for this board. The PXI-6704 will function the same way as any other analog output board. If you are using LabVIEW, then you can easily find a wealth of examples that can run on the PXI-6704 by opening LabVIEW and going to Help > Find Examples > Browse > Hardware Input and Output > DAQmx > Analog Generation

2003年8月3日 · The PXI-6704 can output from 0 to 20 mA. So, make sure you are within this range. Also, the PXI-6704 outputs current on channels 16 through 31 and so make sure you are not trying to use this example with channels 0 through 15 of the device. I hope this helps. Regards, Todd D.

2007年2月15日 · 現在 PXI(PXI-1000B)にPXI-6704を実装して、電流源としての使用を考えております。 申し訳ありませんが、上記組み合わせでの電流源としての使用方法を教えてください。

2016年12月27日 · If you choose a current doubler like the schematic or two current channels, keep in mind that the 6704 has a max output voltage of 10V. Depending on the load/DUT you migth not be able to apply the 40mA! Plot legend: blue: current in R_load. green: current in R1 (or output current of current source I1 -> your 6704)

2003年8月18日 · One voltage output channel on my PXI-6704 analog output module is no longer functioning and I'm trying to determine the cause of the problem. 1) The channel was regularly used to provide +5 V across a 300 Ohm load. 2) Our lab occasionally generates noise on the signal line amounting to an exponent...

2015年7月28日 · Current Setup: PXI 6704 connected to SCB68A. On one of the analog outputs, I have a motor (powered via 24 VDC and controlled by 0-5V via PXI 6704). During power up (powering up the PXI chassis), 0 volts are shown from the 0-5 V ouput. When I shutdown (i.e. turn off 24 VDC power supply and PXI C...
