The use of reminders from prior step to configuration test conditions
I'm trying to set a reminder from the prior step to check the test conditions and correct them if they do not match the needs of the test stage. I was going to affect the test conditions in the before expression of each test step, but unfortunately, I found that expression pre runs AFTER the recall of the pre-trial stage. Is there a way to get around this? How can I get around this? (i.e. to assign specific variables of step before running the recall of prior step).
Thank you
Sean
I did some hacking of preconditions and even its easier than the example above. Do not forget that in TestStand expressions, the comma (,) separates logical expressions. But the return value of the expression is always the return value of the last expression. So if you separate two logical expressions in the prerequisites with a comma, only the return value of the second gets used as the prerequisite.
For example, if you always want to step to run, you can use:
locals.myVar = 5, True
Or if you already have prerequisites:
locals.myVar = 5, AllOf (RunState.Sequence.Main ["ID #:"].) Result.Status == 'Past', RunState.Sequence.Main ["" ID #: ' "]. Result.Status == 'Pass')
In addition, he discussed what order only one not executed his actions. You can find this information in the TestStand reference manual in Chapter 3. There is a table that lists the exact order of operations, including when the engine pre step callback is triggered.

iPad Pro keyboard on-screen despite the use of Create from Logitech
I was quick to connect a Logitech Keyboard create my iPad Pro once I had two in hand. Create keyboard worked according to expectations.
However, recently I noticed that when I have one using various applications the iPad Pro on-screen keyboard blocking half of the screen, even if I type with Create. When I clear the on screen Keyboard Pro I am not able to type with create up to the on-screen keyboard is restored.
Y at - it a known workaround to this distraction? Only, I arrived at Rome and absent an office environment have not noted the applications associated with this problem, but it includes at least Safari but not Chrome.

I also have this problem with the iPad Pro. When you use the Smart case Apple keyboard the on-screen keyboard appears.
I remember long ago when I had the iPad second and attached to a bluetooth keyboard, the keyboard on the screen went. It may be a bug that will be fixed in the next update of the operating system.

The use of reminders with a USB connected instrument VISA?
I have a 34972 Agilent connected by USB to a Windows 7 computer. I'm using LabWindows/CVI and VISA drivers.
I can't find a way to set up a callback that will respond to an alarm on the Agilent event, IE. the Agilent is configured so that certain combinations of signal to generate an alarm (it could be any other event of the instrument-it ends up in the STB registry, similar to that on a GPIB instrument) and I want that my program LabWindows to respond to this event (for example to run a callback routine). With GIPB I ibnotify() etc, but I can't find the equivalent on this combination (USB/VISA).
Any ideas?
Hi HDJ
Have you seen this documentation on how to make VISA event management?
Events in NI-VISA VISA
http://www.NI.com/support/visa/vevents.PDF
At the bottom of page 4 there are some things to consider when you use the callback mechanism. Most important is that you need to install a handler function, viInstallHandler(), before activating the viEnableEvent() event.
Also, you should notice that she is allowed to have a reminder per session.
Agilent also have som of information on usage of the event and the reminder here (page 46):

The use of files from Mac .caf
How?
I have a ton of Mac .caf audio files sitting in Garage Band that I want to use in the first for PC. I can get them on the PC, but the first may not use - at least in its current state. Is it possible to use them WITHOUT having to convert them into WAV or MP3?
Cool; got 'EM, and they'll work with my solution! I guess you do this in Windows, but it should work on a Mac too.
- Download MPEG Streamclip for your OS here: http://www.squared5.com/
- Once you open MPEG Streamclip (no installation is necessary), the select list > list of batches. The batch list window appears.
- Click Add at the bottom of the window and navigate to the folder where the files of your CAF are registered.
- The CAF files do not appear by default, so in the "File name" box, type (without quotes) "* College" to make them appear. When they do, select them all (works of Ctrl + A) and click Open.
- A dialog box appears asking you to "Please choose a task;" in the drop-down list, select the option "save under. No need to check the other options; Just click OK.
- When you click OK, you will be presented with a folder/file browser window; Navigate to your destination folder, and then click OK.
- You will then see a window that says "open file error: unsupported file type." Do not despair just click "Open anyway."
- The next window will ask you to select a file format; Choose MOV, and then click OK.
- Finally, after all, the files will be added to the list of lots with the settings window you just put. Simply click on the Go button and watch the files fly!
The conversion should go very quickly because there is no re-encoding event. MPEG Streamclip is simply split the College container open, by extracting the streams and their conversion into a MOV container. They will also be named the same as your original. CAF files are encoded with the Apple Lossless Audio Codec, which is a legitimate codec to QuickTime, Windows and even in the first, but the container of the FCA cannot be split open by something other than QuickTime (at least on a PC). MPEG Streamclip is an extremely capable front-end for QuickTime; It does pretty much everything than QuickTime Pro (and even more, as the batch) for free.
EDIT: actually, I just noticed that your CAFs have been encoded with AAC audio. the test clip I had was ALAC. Nevertheless, they import very well.
Anyway, you will end up with a bunch of MOV with no video, but audio streams of the ALAC. These perfectly fine imports in the first and you'll have done so without loss; compare the sizes of file and you will see that they are in a few KBs files CAF.
I hope that works for you!

Execution time of a number of steps in a test sequence
Hello
I wonder what is the best way to time the execution of a number of steps in my test sequence, so I can report to a database.
Basically, this time will be the starting time of the UUT and may differ from room to room, so I want to capture him.
Thank you best regards &,.
Don1.
Hi Don1,
A very simple way to do this would be to use an expression before and after to capture time and compare the difference, for example.
locals.startTime = Seconds()
...
measures
...
locals.bootTime = Seconds() - locals.startTime

How can I create a function using variables TestStand and call from Meadow step Expression?
In one sequence, I have dozens of prior Expressions, which are almost the same thing, like this...
Locals.tagID = (Parameters.singlePhaseEnabled? ('L': "D") & Str (Locals.phase) & "006".
.. and the only thing different is this three-digit string in the end ("006" may vary). How can I write a function that I can call from Meadow step Expression then it should look like this? ...
Locals.tagID = MyNewFunction("006")
You can not write custom expressions for commands.
That being said, there are two options:
- Create a sous-suite with a single step. Use a setting of the sequence as "function parameter.
- Create a step type custom including a lower level module that implements the function. Add a step edit to allow the user to the steptype graciously change the setting.
- Store the variable setting in a local global variable / file and change the value in each step. This will, at least, keep the same 'function' for each step.

Use the calendar and reminders without iCloud
I have the calendar, reminders, and Contacts on my MBP on synchronize with iCloud. I have now decided I prefer to use independently of iCloud applications, i.e. with data stored locally on my computer and not sent to iCloud. The problem is when I disable each iCloud in the system preferences application, all my events etc. disappear applications, only to reappear when I check the new box for iCloud syncronisation. I even tried the backup of the archives before "unsyncing" and then restoring from archives of said, but the archives appear to be blank without any event etc..
Any ideas? How can I get data from iCloud on my computer and then stop synchronizing my computer with iCloud?
Reminders - in the application of reminders, drag the item in the section on my Mac. To move several items at once, hold down the SHIFT key after selecting the first reminder.
Contacts and calendar - file/export and choose your desktop. Turn off sync iCloud. Then file/import the file appropriate to your computer.

Hello
We need power RF amplifier with a function generator to create plasma in an ion source. The signal pulse duration must be 1ms long, repeated twice per second.
Today, we work in the following way: we spend the RF with f0 (aprox 1,995 MHz) frequency. After 20, we send a trigger signal passing frequency f1 (aprox 2.005 MHz). We keep this frequency for the rest of the pulse. However, the plasma that we generate is not 'constant' or stable during the whole impulse. If we smoothly change the frequency during the pulse we could improve.
We would like to do: use the frequency sweep: rather than use this frequency hopping, we would like to move smoothly f0 f1 (frequency scanning). Then F1 to f2.
As we have a PXI for data analysis, we believe using the arbitrary function generator of NOR: 5406 of NEITHER allowing the frequency sweep. However, in the book loads, it is not very clear, and I have a few questions:
-We can create a "list of frequencies. In the site OR below, it shows that the "minimum of Step' is 1.28us, which would be ok for us (I understand that the"minimum duration of Step"is the minimum time between 2 frequencies). However, the manual of the device "NI PXI/PCI-5402/5406 specifications" said the frequency list has a time step of 1 ms to 21s. What is the good?
-It is also said that the "duration of minimum list" is 1 s. For us, need us a shorter list that 0.5 seconds (we need to repeat the same pulse twice per second.). Is it possible to do what we want?
-At the end of the day, we would like to implement a control loop which modifies the list of frequencies in real-time.

Thanks for your help.

Jose.Hi Jose,
You're right about the inconsistencies of the documentation. The minimum step was of 1 ms, but was changed to 1.28 µs to driver version 2.6. The help document has been modified to reflect that, but the specifications were not. I'll make sure that attaches.
The length of the minimum list is not listed in the book loads, and the latest version of the help the signal generators OR (driver version 2.9) lists the minimum list than the 1 step length. Aid has changed to the driver version 2.6.1 to clarify that the 1s meant 1 step. I've attached a screenshot of the help of the most recent.
There is an example that is installed with the NOR-FGEN driver called "Fgen Sweep Generator.vi". I would recommend from this for your application.
I hope that some of the inconsistencies in our documentation brightened. Please let us know if you have any other questions.

Original title: Windows updates
Is the function of automatic update of Windows found in the use of control panel of your compensation for the use of the Internet from my ISP? If so, how? In addition, how to hide an update, I don't want to? For example, I use (and I'm happy with) Windows Internet Explorer (v7), but receive reminders to update update to Internet Explorer v9, which I don't want.
Is there a way to prevent Windows Update for sending this reminder in the future?

Hide and Yes will use you PSI data usage. It depends on how much the updates install you, on the amount of data it uses

What happens if my default printer is not the printer used for printing from LR?
Hello
I use an Epson Stylus Pro 3800 for photographic printing, but is not the default printer on my system (and it won't). How I setup LR do use the default 3800? I tried a "default printer" option in the preferences but could not find it. Or have I missed something? I can't imagine there is no way to solve this problem.
Thanks in advance.

Are you aware that you can save the printer model in print templates with page size, printer profile, etc.? Once the printer model is saved in the model, you must only select the model FRO Lightroom to automatically choose the correct printer.
The steps are:
1. start Lightroom
2 go to the print module
3. create a new print template and give it a name meaningful (for example model of printer - A4 landscape)
4. click on Page layout (it would be more logical if he actually read the Print Setup)
5. choose the model of the printer (for example Epson 3800) in list menu dropdown name printer - paper set size and orientation
6. click on the properties button and configure the driver Epson as required (for example Page Size, the printer settings, etc.), and then click OK twice to close the properties of the printer and the print dialog settings
7. right click on the model that you created in step 3 above
8. choose update with current settings from the popup menu
If you define profiles of specific printer that they can also be saved to the model

I am trying to create a generic message using LVOOP logging class. The recorder would include information on stage during execution (name, sequence, etc.). I would like to create the message object log and then move it into another object (communication, controller of oven, etc.). Everyone should get its own copy. None of this is a problem to date.
I found ways to gather the necessary information to ThisContext. However, this only seems to work if ThisContext is spent in running step. If I want ThisContext in LVOOP, the next step to try to use causes an error 1 "an input parameter is incorrect." Is it possible to get this kind of information (name, sequence, etc.) without ThisContext in at each stage? It would be inappropriate to do so, but if necessary I will. It does not go against LVOOP.
Summary: Can I hold ThisContext go a step and use it in a later step to find the name of the current stage? If not, is there an effective way to do this?
My solution was to store the reference to thread. At each step, I can retrieve the current context. This is valid only in a thread, but meets my needs. I could also move something to a higher level, but it would need to know the thread that interests me in any case.

Looking for a compatible printer AirPrint for use in the field to print from my iPad 2. Own and use very satisfactory wbt 460 HP with a laptop. All compatible printers AirPrint currently all-in-one and too big for travel or field use.
Whereas several HP printers are among the 15 AirPrints currently on the market, it seems reasonable that HP could provide the upgrade that would make my 460 AirPrint compatible wbt.
I wireless (my fi) and would like to buy the wireless card from the blue tooth, if only the upgrade of the driver was available.
How and when HP can provide a mobile/trip AirPrint printer?
Answer as I am a person of 70 years. Because I am and can be quickly way over my head!
For now, we don't have an Airprint-compatible printer. Future products may include, but are not currently. Products that are compatible Airprint are designed this way, so no upgrade will take place for previous models.
