Hello,
I am connecting a somewhat large resistance to the input of a PXI 6255 card, and I'm worried about the time constant at the input possibly being too large. What I'd like to know is what is the input capacitance of the card, or at the least, what is the time constant for my setup? I'm currently using about 200kOhms, and it really couldn't get much lower. Thanks.
I need to load XP from scratch on a PXI 8115 Embedded Controller. I have only found drivers for Windows 7 and PXIe.
Does anyone know where I can find these for PXI 8115 Embedded Controller? Thanks in advance.
Hello,
I was wondering how the grounds from the hybrid slots of a PXIe 1073 chassis are connected within the chassis. I'm using 3 PXI 6255 cards, though I don't believe that makes a difference. What I'm looking for is whether they are tied together or not, or similar information. Thank you.
Hi all,
I am new to PXI controllers, i am having a few issues with a PXI controller in my university which i intend to use for my fyp project.
So we are using a PXI 1042Q chassis with a PXI 8106 embedded controller.
We started this controller for the first time and updated windows xp, we also removed labview 8.6 that came with it and installed labview 2010 with all the available drivers, softwares and liscenses..
When we start windows XP on the PXI system we can see the PXI chassis and controller identified in MAX but labview cannot find them when creating a project.. My first question concerns the reason why labview cannot identify PXI targets in a project?, could it be a missing liscence (for instance RT liscence for PXI)? or an improperly installed driver? How to check if RT liscence is missing or needed?
Due to the first problem, we tried to control the PXI remotelty from another desktop host PC where we found more problems.
1/ Can we make a connection in order to download a project from the host PC to the PXI via ETHERNET (without MXI cards) ?
2/ We tried to make the connection using ethernet but we couldnt configure the IP; when we switch to safe mode to configure, the pxi gives the following texts on screen " system error kernel 446610 LFS error not a dos disk pc-dskinit " and the system remains unconfigured with the 0.0.0.0 IP due to the failure to boot, MAX on the host PC sees the PXI as a 0.0.0.0 and changing the IP is not possible also.
To cure this issue and help the system boot, we created a desktop PC utility USB Drive in MAX (on the host PC), configured the boot devices priority on PXI and booted the PXI from the USB drive. we entered safe mode and the pxi took an IP automatically and then it displayed that the software is not present... The problem is that when we tried to install the software on the pxi using MAX on the host PC (which now sees the PXI) we got disconnected..
Note that firewall is off, the host pc has an ip in range with the one generated by the pxi, on the same subnet and has windows 7..So why are we loosing the connection in MAX after 30 seconds,, when we try to install the software on the pxi?
thank you in advance for your help.

I tried using the RFSG CVI example for Start Trigger Hardware Source. When running on a PXI-5673, the pulses keep going forerver even if the trigger is no longer there (Hardware trigger is removed).
I'm trying to do something similar and it would be great to have an example that is syncrhonized with an external hardware tigger.
Also, how can a delay be added in between pulses, so when a trigger is received there is a delay, then some pulses sent, then stops until another trigger happens (and this sequence repeats).
Thanks
The Monitor goes on standby (blanks out) randomly while my computer is still on. I've narrowed the problem down to the controller. I just want to know what options I have. Is there a part in the controller itself that I can replace?
Hi all,
I am currently using a PXIe-1082 chassis, which is linked to my laptop via an MXI cable from an 8360 expresscard in my laptop to a PXIe-8360 controller inside the chassis. A PXIe-4492 card is also installed in the chassis. Everything was working fine, until today when I removed the MXI cable to move some hardware around.
Since I reconnected the MXI cable and switched all the hardware back on, the link LED on the chassis has not switched on despite multiple laptop restarts (the power LED is green however). When I open the measurement & automation explorer,"NI Expresscard 8360" is in the device list, but neither the PXIe-1082 chassis or installed PXI-4492 card are listed.
Can anyone offer any advice on rectifying this?
Thanks for your help!
Are there any examples for this card using RLP and nimhddk on Linux?
I've bee able to get the serial number using them M-series serial number tool.
Thanks
how to generate voltage using pxi-7340?
I'm trying to set up two Pickering PXI chassis in my test tower and the current pxisys.ini file is set for only one chassis. I copy in the appropriate information for the second chassis and when I reopen MAX, the original ini file is back. Is there something that MAX is doing to cause this?
Hi!
I am using two high speed digitizers NI PXI 5124. I am running a continuous acquisition as in the attached example. I have two questions:
1) Is it possible to realize the continuous acquisition using some other trigger source instead of software trigger?
2) Depending on the answer on the first question - how to synchronize the two digitizers? In the attached example the digitizers have the same clock source and they receive the same clock synchronization pulse so the sampling frequencies are the same, but there is a random phase shift every time I start the acquisition.
Thank you!

Hello
I want to obtain the serial number and manufacture and model of my attenuator. I am using Agilent M9168x.lv to open it with string PX15::12::0::INSTR. I have been able to get the same information for the agilent signal generator using the attached vi . But I cannot figure out how o get the info for he attenuator.

Hi,
I have four asynchronous data generators with same frequency. Is it possible to have multiple sessions to HSDIO acquisition so that I can acquire the data from all the four simultaneously using a single PXI card.
I am trying to use PXIe-6535.
Regards,
Tiru.
I need to Generate the pulse train output so as to get the Angular position in the form of the Waveform Pattern. I am the using PXI 6602, PXI 6259 for generating the Pulse train. The Condition is that Say 10000ppr has to given the for the servo drive to get max degree that is 360 degree which has to ramped in form of sine(ie. 0 360 0 -360 0. For controlling the CCW direction I have one Pulse output and vice versa for CW direction
I have a PXI 8101 and purchased a 7 port usb hub ( manhattan ). When I plug it in and connect it to two ( a seiko printer and cd read/writter) external USB devices they dont work. If I take out the hub and connect the 2 devices directly to the usb slots on the 8101, they work.
8101 is running Windows 7
usb hub is 2.0.7...could this be the problem?? how do I tell which usb driver I have ??
I tried pwring down then open w/o sucess.
usb hub is externally pwr'd
Thanks..
Hi all,
According to the specifications, the PXIe-4140 SMU has a maximum sampling rate of 600 kS/s in continuous acquisition mode. I would like to know whether the card uses any kind of internal buffers while running in continous acquisition, or if the continuous sampling speed is limited by the PXI/PCI (or host software) occupation.
Apart from that, to operate it in continuous mode, is it necessary to provide a continuous trigger or it is possible to set the sampling speed and have a stream of measurements?
Many thanks for you help!

P.S.: Please, let me know if I'm posting in the wrong forum thread.
Hello.
I have a PXI chassis PXIe-1071 with controller PXIe-8101 (Windows XP) and PXIe-4496 module. Also, I have NI DAQmx installed on controller OS and on another computer in same network.
Is there any way to acquire measurement data from this ADC on network computer using remote access? Or this functionality available only if using real-time controllers?
Thank you.
Hello,
I have three PXIe-4499 simultaneous samples modules in a PXIe-1082 chassis.
I built a single AI voltage task which includes all the chnls on the three modules.
Do I need to do anything special to ensure all modules use the same sample clock?
I generated niRFSG.mdd and implemented MATLAB code to do the same thing as the ScriptTrigger CVI code. However, an error occurs when calling
invoke(sig_gen.GenerationConfigurationScripting,'writescript',waveformscript)
NI PXIe-5673E
The instrument returned an error while executing the function.
You cannot set the Power Level Type to Average Power in Script Mode. Either change the Power Level Type to Peak Power or use the Arb Waveform Mode.

Error using icgroup/invoke (line 93)
The instrument returned an error while executing the function.
The AWG reported the following error:
Error in niRFSG_test (line 66)
invoke(sig_gen.GenerationConfigurationScripting, 'writescript',waveformscript)
First of all not sure why I'm getting the Power Level Type warning since I'm actually using Peak.
invoke(sig_gen.Generationconfigurationconfigurewaveform,'configurepowerleveltype', 7001) % 7000 - Average, 7001 - Peak
I look into the second issue (script issue) and it seems like inside the .mdd generated code is not working correctly. When I replace invoke(sig_gen.GenerationConfigurationScripting, 'writescript',waveformscript) with my own local function call (by copying the actual writescript function from .mdd to a.m file scripttest(sig_gen.GenerationConfigurationScripting, waveformscript)
It seems like the problem is right here:
status = calllib(libname,'niRFSG_WriteScript', session, Script);
I noticed the same calllib is done for other niRFSG functions and it works but for the WriteScript it does not. Please note that the same call in C or C# works great.
I have been talking to mathworks support about this issue. They are still investigating. But since the instrument is generating this error, The instrument is informing through NIRFSG driver that the power level is set incorrectly, but most likely this error is regarding some other parameter set out of range. Perhaps this is causing the issue with the writescript. Can you provide any support to figure out this issue?
Thanks!
