• Pulse or measure of separation of two edge with implicit synchronization in ticks: what about minVal and maxVal?

  When I pulse or measure of separation of two edges, using the implicit synchronization, DAQmx chooses (I think) an internal time base appropriate for the measurement. My X series on Board (a 6320) has for example a time base internal 100 MHz. I think I can apply to the use of a base of specific time (using the Set accessor of property DAQmxSetCICtrTimebaseSrc to set the counter to the value '100MHzTimebase' time base). But the docs of the DAQmxCreateCIPulseChanTicks and DAQmxCreateCITwoEdgeSepChan functions (this last one called with the parameter to the DAQmx_Val_Ticks units) make me spend a minVal and maxVal. Apparently, these values are used to determine a time appropriate for the implied timing base (internally). But how to choose the specific digraph/maxVal values? They are obviously dependent on the time base, so it's kind of a situation / the hen's egg. Should I just say '1' or '0.1' or even '0 '? Because I * want * the time of 100 MHz, to use base. Or can I simply call the DAQmxSetCICtrTimebaseSrc after DAQmxCreateCIPulseChanTicks?

  1. When you use "Ticks" for units, digraph must be > = 2.  DAQmx does not support measures of 0 or 1 "Tick" of a time value.

  In general, the parameters that minVal and maxVal are mainly useful for people who are measured in scientific units such as seconds.  They allow DAQmx do the dirty work of correlation required range of programming interface with the basics of time available to the Agency and to make a judicious selection automatically.  For people like you measure in ticks, DAQmx won't do the thinking for you anyway, so just give them plausible values.

  2. Thus, maxVal must simply be a valid 32-bit integer.

  3. Yes, you can explicitly configure to use the time base of 100 MHz after the creation of the task, no doubt thanks to the function, you said "DAQmxSetCICtrTimebaseSrc".  (I do my programming in LabVIEW and don't know the syntax of the api code text driver.)

  I believe that if you do not explicitly choose a time base for a task using ticks as units, the Council will use its default time base.  I know there is an api function in LabVIEW to interrogate the database after creating a task, perhaps you have an available too?

• Pulse output PXI - 5122 PFI

  PXI5122

  It is not very clear if I can do this, but it is

  possible to arm the PXI5122 (pending a

  either PFI lines?

  The PFI 5122 trigger material ext and

  Hello

  Yes, you can use the niScope export Signal.vi to produce a digital on one of your lines PFI pulse when a certain condition is met.  From your post, it seems that you may already use this VI.  I have attached a screenshot of the Signal VI export and included context-sensitive help and detailed about what parameters to signal help is available.

• NI 9401 pulse width measurement.

  Hello

  I'm not sure that I understand very well the pinout diagram. At the present time, I have a NI9401 in a NI 9172 chassis.

  DIO0 and DIO1 are connected at the gates of light. I have an opto switch and I want to measure the pulse width when an object blocks passes through the slot. Can I use one of the other free entry of the for do?

  The entries are DIO2, DIO4 and DIO5.

  The other IO pins are used as triggers.

  See you soon

  Hi Kamilan,

  If you explore in the measurement and Automation (MAX) and find your 9401, you can right click on the device and select "Pin of the device" which pulls up a window that says what features each pin on the device.  For example, according to this document, DIO2 is PFI2 to THE CTR0 CTR0 B and FREQ OUT.

  To answer your second question, do a right click on your device and create a new task for your 9401.  "You should do an acquisition of signals" counter input "pulse width and select CTR 1 on your device.  Once you do this, you can configure the parameters of your task and Max it will tell you where you need connect your signal source, which, for me, is DIO5.

  I would like to know how it works for you, thank you!

• Pulse/counter of encoder data wrong servo motor

  First of all, I am very new to the use of labview.  I'm trying to complete a project, a former employee was working on that.

  For a quick background on what I'm working with, I use an NI DAQCard-6036E connected to a SC-2345.  SC-2345 is then connected to a load cell, Omron R88D servo driver and an omron servo motor.  The actuator is an incremental encoder with resolution of about 2048 pulses per revolution.  My labview program includes a counter that records the data of the encoder on the servo-motor.  I was able to get accurate data during the test through the program of measurement and automation of the engine manually.  Also when running through the specific DAQ assistant, I use for my counter, I'm getting correct readings by turning manually engine.  Once I run my full program, instead of get 2048 pulses per turn, I'm between 34000 and 36000 pulses per revolution.  The more logical assumption is that I get vibrations in the engine itself or some kind of noise disturbs my signal.  First, I tried to change the possible settings via the omron servo driver that could reduce the vibrations of the engine.  I try to change the stiffness settings, enable, and disable the automatic adjustment feature and a few other parameters specified by the user manual which could cause vibrations.  If turn the settings from rigidity as low as possible, I am able to get around 2000 impulses per turn, but data are very sporadic. In addition, my equipment must be very stiff, and with setting the lower rigidity for the servo driver, I can almost stop the engine with a minimum of force.  My equipment must be able to travel at a near constant speed with fluctuations of up to 200 N force.  Any suggestions on the direction in which I should go in search of a countermeasure?

  Thank you

  Experience with actuators is that they can produce large quantities of electrical noise.  I guess that noise can enter the signal of coders.  Look carefully at your wiring and make sure that you do not have a ground loop between your hardware OR and the actuator.

• HP/Agilent 33120 A pulse, use burst mode

  Hello

  I'm trying to trigger a pulse of demand on from a HP 33120 A function generator.

  The pulse must be a 0 - 5V simple, with frequency/period adjustable ramp. I was able to get as much of the FG by use of burst mode and trigger manually on the front panel. Now, I would like to get the same functionality from a LabVIEW VI.

  Although there is a driver for the device, the burst feature is, unfortunately, not applicable to the model that I use. I found a similar problem on the forums and follow the code of the SCPI provided in the answer with some of my own humidification (http://forums.ni.com/t5/LabVIEW/33120A-Pulse-Mode/td-p/1088106).

  Unfortunately, my VI does not produce the same waveform as the manual release out of the front panel. It hovers at the offset value and gives me a few square wave to zero when I run the VI. Square waves are spaced oddly and I usually see 4-5, even though I specified 1 cycle in VI. The 33120A reading, I feel that this is of my do not turn off the previous signal but, if this is the case, I can't understand how I would do.

  I start to move away from using only the drivers by changing the code of the SCPI, but I'm still pretty new to this. Would appreciate some advice on what could be the problem. I modified my original VI twice; Once configure only the FG burst wave parameters manually and one just put up the waveform with no shine. The first don't not gave me much better results and the works of the latter very well so I'm back to the question of thinking are in transition.

  I enclose the original VI (b) with the two modifications to the case where (c and d).

  Hope to hear from you,

  Yusif Nurizade

  Edit: Burst chain should say TRIG: SOUR BUS instead of EXT, although neither works.

  Or you have the appropriate firmware in you function generator?
  Have you checked this with Agilent?

• Pulse 500hhz signal

  I use the USB-6251 daq card. I need to measure the number of pulses is entered a few start and end time with the saignal may vary up to 500 k hz. Also I need the arrival time of pulse for every pulse.

  If I configure the task for pulse width tab in daqmx I'll be able to measure the time of arrival count pulse and pulse (up to 500khz)

  I guess what you are the reference to is the time stamp. When you use the low level of VI of DAQmx you can get signals as data type of waveform, which has the moment t0 and initial sample, although dt values sample sampling intervals Y. You can do the rest by getting each of the parameters in the range of the waveform.

  I hope this helps!

• Siri App Suggestions independently displays parameters in the iOS 10

  Hello

  I was wondering if anyone has seen this before and he knows a work-around?

  I am unable to turn off Siri App Suggestions, I did the classic general > Spotlight search > Suggestions of Siri which I turned on or off times shared with restarts, but it still shows.

  I even went as far as everything off in Spotlight search including all applications which has been laborious, but it still shows, guess it's bug, but I was wondering if someone else he met and may know a work around.

  Hello John H0.
  Thank you for using communities of Apple Support.

  If I understand your message that you want to disable the Suggestions of Siri. You started with a few great troubleshooting by enabling / disabling the on/off function again, restart and turn off everything in the Spotlight search parameters. The next step, I would recommend would be to reset all the settings. First of all, if you already create a backup file. Reset all settings returns settings to their default settings. A backup will allow you to return your old settings of your device. Once you have reset all the settings to disable Siri Suggestions again.

• Homekit missing parameters

  I recently bought a few lights of hue and the new hue Bridge 2.0 (HomeKit Compatible)

  I am running iOS 10 on my iPhone 6 s and the latest version of tvOS (9.3.3) on a new 4th generation Apple TV.

  The new home app works correctly, which allows direct control from lights.  Apple TV works fine for the tasks of automation that have been configured in the application of the House.

  However, I am not able to connect to my lights when I'm not connected to the local WiFi network.

  Reading the various forums, there should be a HomeKit element in the application of the main parameters and an option to reset the HomeKit configuration in the privacy settings.

  Two of these elements are missing on my phone.  I have the factory to reset my phone and used an alternative iCloud account and settings appear, to go again when I have to reconnect my own iCloud account.

  

  When I login with another account HomeKit appears in the first picture under settings, and the ability to reset the HomeKit configuration appears in the second.

  The only information I can find suggests turning on/off, no change keychain.  I also have factory reset the AppleTV, the problem persists.

  My guess is that my data HomeKit has been corrupted in my account iCloud, without the reset option I am rather stuck.

  Any ideas to fix this would be appreciated!

• In Firefox 39.0, I have a missing folder to store Twitter design parameters (background theme). What is the name of the missing file?

  Firefox 39.0 must store parameters for design background Twitter. This unknown file should be here in the help of Firefox, troubleshooting information, profile folder. This who should I name a new folder to save the twitter background design choices?

  Sorry, I don't know exactly what you are doing.

  If it's an arrangement on Twitter, the site probably will set a cookie and could use the storage offline (but will most likely just use a slightly different page and do not store images locally).

  If you plan to replace the background normal Twitter with something different to your own choice, were you plan to use a custom style rule or an add-on of a certain type? The technique has probably determines the location.

• Please specify how sync works - I can't find a clear explanation anywhere! Parameters are be replaced? I think I lost a few bookmarks during a sync?

  I have 3 copies of firefox. I want all 3 to keep the same settings, bookmarks, etc.. When I open my browser in A device, and it starts to 'synchronize', it download my current settings for a server, or is it download the settings from a server?

  If I add bookmarks to firefox in the device, & then I add bookmarks and change some add-ons for firefox in device B, all the bookmarks and the modules will integrate? Or is the server by replacing the previous information from the device?

  My browser is not automatically connected whenever I open it. That's why I have lost a bookmark or two during the last sync I did? There is an error message telling me to re - connect with sync, & I don't always immediately.

  Is the problem that my password is not saved. I don't want Firefox to save passwords of websites.

  Hi alyab987,
  All parameters are the merger on the server and then distribute the merged at each Firefox facility attached to your sync account.

  Each of them will merge. It will only merge the settings that are selected to sync.

  Sometimes, the account will be dislocation. It is possible to test this by enabling / disabling or not Firefox stores passwords. I don't know what caused your computer disconnect.

  In order to disable the synchronization of your account passwords, click on any Firefox menu, then sync account name. Just make sure that the "passwords" are unchecked.

  I hope this helps.
