How to get Digital waveform with Time.

Hi
I have 3 channels , each of which have ON/ OFF cycles specified with milliseconds as shown below.
Channel 1       OFF(3000) ON(2000) OFF(1000) ON(500) OFF(4000) ON(300)
                     The number in the bracket is the time in milliseconds for which the channel has to be ON or OFF.
Channel 2      OFF(800) ON(1000) OFF(6000) ON(2000) OFF(5000) ON(400)
Channel 3       OFF(1000) ON(700) OFF(500) ON(800) OFF(400) ON(600)
So i need a digital waveform plot with Y axis showing the highs and lows for the channel and X- Axis showing the time in milliseconds.
All the channels can be plotted in one graph or separate graphs.
I tried plotting with each OFF as False and ON as TRUE and built a boolean array. then converted to digital. but was not able to get the time (X-axis ) correctly. Is there any way to get Time on X axis for the Digital channel.
Thank you .Regards. Hema.

Hi Dennis,
I have done the same way as you suggested.but the sample rate is common to all the channels.( that is each channel is one boolean array column in the 2D boolean array which is fed to the Digital function , but i need separate sample rate for each channel(1-D array).
The Boolean array to digital takes 2D array as input, so i was not able to get different Time on X-axis.
But i found out a solution( very long method) by building time array separately and plotting the waveform without using sample rate.
Now i want to get rid of the '1' and '0' which gets displayed on the digital waveform by default . That is for every high there is number 1 shown and every low number 0 is shown on the graph. Please can I know how to remove this number display.
I saw digital waveform example too, but on all digital waveform, the numbers are shown. Is there any property to be set to disable 1 and zero display.
Thank you.

Digital Output With Timer (Simulation)

Hello everyone, I just learned how to make LabVIEW program a week ago. I try to make a simulation of Digital Output by LabVIEW (my attachment). In this simulation I have a slider as an input (0-10 V), two numeric control (upper limit and bottom limit), a waveform chart that plot those 3 value, and two boolean LED (P0.0 and P0.1) as an indicator. In this simulation you can fill any number (between 0-10) in the numeric control as a limit for your slider input. If the input from a slider exceed those upper and bottom limit then the boolean LED will turn on, P0.0 if exceed upper limit and P0.1 if exceed bottom limit. The problem is I don't know how to make timer for those boolean LED. As example:
1) Make an input from slider,
2) If input (1) exceed the upper limit,P0.0 will turn on for 5 second,then turn of for 10 second,
3) If in that 10 second you change the input back to normal (between upper and bottom limit) then P0.0 will stay turn of until the input from slider exceed the upper limit again,
4)If in that 10 second you didn't change the input (stay exceed the upper limit) then P0.0 will repeat the process (2) until you the input from slider back to normal.
(Same process for input that exceed the bottom limit).
Can you help me to make this timer? Thank You (I'm sorry I made a double post):newbie

Digital Output With Timer.vi ‏16 KB

Hello Juventom,
As I understand it you want to be continuously checking the value of the sliding bar and comparing that to the upper and lower limit controls whilest also chaning the LED booleans to true for 5 seconds then false for 10 seconds if the sliding bar value is outside of the limits.
To do this you would probably be best using a parallel loop design, where you have 3 while loops in place of the one you have currently. Each one of these while loops would be responsible for a part of your program (e.g. the top one would display your values on the graph and the second one who check the sliding bar value against the upper limit and then turn on the LED, etc)
I've found this tutorial about multiple loop programs and I think you should look at the section entitled "Parallel Execution"
http://zone.ni.com/devzone/cda/tut/p/id/3749
This way you can use normal delay VIs but when they run they only pause that loop rather than the whole program.
Please let me know how you get on with this, and ask me if you need further help.

How to send digital waveform to the DAC?

How to send digital waveform, obtained by Function Generator.vi to the Digital-Analog Converter? What kind of subVIs I have to use for this? I have LabView_5.0 on MacOS.

The 6032 is not a GPIB board. It is a DAQ board board and has 2 16-bit analog outputs, 8 16-bit outputs (16 single-ended), and 8 digital i/o lines. I don't know what you mean that a MIO16/LPM16 is connected to it. There are a lot of example VIs that ship with LabVIEW. Select Find Examples from the help menu and look under Hardware Input and Output. LabVIEW 7 has some under DAQmx>Analog Generation and older versions of LabVIEW have them under DAQ>Analog Output.

How to get command history with timestamp ?

how to get command history with timestamp ?

If you are using bash:
HISTTIMEFORMAT If this variable is set and not null, its value is used as a format string for strftime(3) to print the time stamp associated with each history entry displayed by the history builtin. If this variable is set, time stamps are written to the history file so they may be preserved across shell sessions.

Jitter of output digital waveform with external clock

Hi,
I need to generate digital waveform with 20 bits pattern * 1000 times. Digital waveform must be sync with 1 MHz external clock.
It is not big deal.
But there is additional requirement that digital waveform has jitter < 200 ps. It can be delayed for couple ns but it must be very stable.
Can anyone point me on that parameter? Or share your expirience?
Thanks!

Hi Andrei,
Tph on figure 3 is defined as tp - 2.2ns as we discussed earlier. The data jitter, along with channel to channel skew, is already taken into account. We don't specifically spec the data jitter since we have made this calculate for you. It is safe to say that the data jitter involved in tph is less than 200 ps however this is not a standard spec we provide.
As for additional board recommendations, what is your application? The 6562 is designed for LVDS applications. The 655x series is highly recommended for high speed TTL based applications. If you reference the 655x manual you will notice similar or better specifications in regards to setup and hold times, which again already take into account data jitter and skew.
I am curious as to why you would like the specific values documented. We provide the current specifications so that you do not have to use the individual statistics to calculate numerics such as the setup and hold times. Is there something specific you are trying to do here? You mentioned a simple example earlier, what is your actual application?

How to get rid of the "time out" when using DAQ AI in the example program

I try an example file called "AcqVoltageSamples_IntClkDigRef" (Visual C++ .NET). It works great. However, if the program has not recieved the data, it sent out a timeout message. How to get rid of the "time out"? I cannot find anywhere in the code. Is this a property I have to reset somewhere else?
Thank you,
Yajai.

Hello Yajai,
The example program will use the default value for timeout, 10 seconds. To change this, you will have to set the Stream.Timeout value. I inserted this function into the example and set it equal to -1, and the program will wait indefinitely for the trigger signal without timing out. Please see the attached image to how this was implemented.
I hope this help. Let me know if you have any further questions.
Regards,
Sean C.

i have a problem with mail. the spelling and grammer check box before sending the messege is no longer there. I did everything but cannot get it back. is ther anyone who knows how to get the box with spelling and grammer checks before sending the mail.
Also the mail is acting very funny by not getting the rules work in a proper method. Is ther a software to repair mail.

i did both of them, but still the while sending the mail the diolog box is not showing up and also the spelling and grammer does not do the spelling check.
This problem just started for about 3 to 4 days now. earlier it was working normally.

How to get the table with no. of records after filter in webdynpro

Dear Gurus,
How to get the table with no. of records after filter in webdynpro?
Thanks in advance.
Sankar

Hello Sankar,
Please explain your requirement clearly so that we can help you easily.
To get the table records from your context node use method get_static_attributes_table()
data lo_nd_mynode type ref to if_wd_context_node.
data lt_atrributes_table type wd_this->elements_mynode.
lo_nd_mynode = wd_context->get_child_node( name = wd_this->wdctx_mynode ).
lo_nd_mynode->get_static_attributes_table( importing table = lt_atrributes_table ).
Note: You should have already defined your context node as a Dictionary Structure.
