What example would I use to measure emission current and leakage current (voltage vs. current)?

I need help on measuring current @ anode (emission) and leakage current @ (gate voltage).
Using gpib config.

I don't think you'll find any examples that suit, but that's life. It's rare
to find someone doing the same work with the same kit when more than one
instrument is involved.
Keithley should have examples for the electrometer that show you how to set
it up and take readings via the GPIB- that's the harder of the two
instruments because it does more. If they're not shipped, look on
www.keithley.com, since they have a large selection of example Labview
programs for their hardware- though I know nothing about that particular
instrument.
The power supply should be trivial; it should just have commands to set the
voltage (and current limit perhaps) and switch the output on and off. This
may be a good thing to learn to do GPIB programming on since there's
very
little involved. Check out the example
examples\Instr\smplgpib.llb\LabVIEW<->GPIB.vi to see how to send commands
and receive responses. Once you have a program that provides a sequence of
power supply voltages to your device, then start playing with the
electrometer examples and making something to read the current. Then put
them together and write a top level that builds a current/voltage plot for
the device.
I assume there's no problem with the physical connections and how to wire
the test device up to the instruments? That's out of the scope of this group
in any case.

  • What sensor should be used to measure speed of motor

    Hi,
    I am using NI PCI-6624 to control the speed of dc motor. I have used "PWM-Counter Output.vi" example to generate PWM pulses to control the input power of motor. I am using "counter output" and "analog input" terminals of PCI-6624. Counter output terminal is used to generate PWM signal and "analog input" terminal will be used as an input from speed sensor.
    Can someone tell me what sensor I can use to measure the speed of motor. Please note that the output of the sensor will be the analog input to PCI6624, so it is essential that speed sensor's output is ANALOG.
    Please help me in this matter and tell me which sensor can be used and from where I can buy it ?
    Thanks

    Ayaz,
    the straight forward low-cost solution for velocity measurements is using a quadrature encoder. With your  DAQ device you could use the second counter of the board to measure the frequency of one phase, but that's jus one option amongst others.
    I haven't come across sensors that output a voltage that is proportional to velocity but expect such a device to be much more expensive and probably less accurate.
    Do you plan to do closed loop velocity control? Are you using Windows or a realtime system?
    Kind regards,

    You can do something like this:
    D2=B2*(1+C2/100)
    this means in the cell D2 type the following "=B2*(1+C2/100)"... leave out the double quotes

    Benje001,
    Right-click on the CWAI control on your form. Choose Properties. The first tab is the Channels tab. After you choose your device from the drop down box on the right, you can type in the Channels box which channel you want to use.
    If you want to see a CWAI control that is already configured, all of the shipping examples will have this already done.
    Also, if you have questions about any item on the CWAI (or any other NI ActiveX control) you can click the ? icon in the right corner of the properties page and then click on the item in the dialog that you need help with. This "What's this" help will describe that particular control on the dialog.
    Hope that helps!

  • What exact metals are used in the iPod 5 and what for?

    what exact metals are used in the iPod 5 and what for?

    Hey Connor and Josh, The same kind of metals that are found in pretty much all electrics. Aluminum, Gold, Copper, Solder, (I would guess lead free). You will also find plastics and resins, glass and Li-ion, carbon, and silicon. Why do you ask? If your thinking of stripping one down for the metals, it's not worth it, there so little in there it will cost you more to separate the metals than there value by weight.  Cheers.

    Aren't the answers given in PL/SQL forum sufficient enough?Well, as the first answer in that forum directed the OP to this forum you can hardly blame them for the repost.
    There is some high-level stuff in the Concepts Guide. If that is insufficient the OP will need to tell us what more details they need to know (and perhaps why).

  • What function would you use instead of "IF" when referencing durations from a pop-up menu. Ie; if c4 equals 1h enter 280, if c4 equals 30m enter 160, etc. IF works fine if c4 is formatted as text but returns 0 when formatted as pop-up.

    What function similar to IF would one use when the reference cell is a pop-up menu of items in duration format?
    Example: if C4 equals 1h enter 280, if C4 equals 30m enter 160, etc
    i can get it to work fine if I format the cell to text but I not only need it pop-up, I also need it to be written in duration format because it's used as duration in other functions.
    thank you for your help in advance
    Christina

    Hi Christina,
    A screenshot is always helpful.
    C4 is your popup? You want to chose a duration there and have 280 or 160 show up somewhere else? Are they the results of a mathmatical formula or do you want a lookup table to show them?
    I suspect something else is going on in your table. I have no trouble having a popup recognized as a duration:
    The formula in C2  =DUR2MINUTES(B2) displaying "60" as expected. Note that "60" is not a duration. If I want C2 to be a duration I need the formula to read:
    =DUR2MINUTES(B2)&"m".
    I hope this helps, if not, post a screenshot including relevant formulas.

    Utterly bizarre. I can't see your two follow-up posts when I'm logged in. However...
    Things would be simple if Apple implemented Data Detectors for dates in Numbers, as they have in applications like TextEdit and Script Editor. Then you’d have a system-level means of quickly moving from a selected date in your CRM spreadsheet to Calendar.
    Until that happy day arrives, though, we can approximate it with AppleScript and Automator.
    First, make sure your Numbers table is called CRM and your column has the header Next action required. (You can change these if you want but you’ll also have to modify the script.) This is the basic setup:
    Then, launch Automator and create a new workflow. From the Choose a type… dialog, specify Service.
    At the top of the workflow, “Services receives selected…” should be set to text in Numbers.app. (You'll need to choose Other... from the pop-up and then navigate to Numbers.)
    In the Library menu at the left, click on Utilities, then drag a Run AppleScript action into the main Automator pane. Delete all the boilerplate text from the script.
    It should look like this:
    Now copy and paste the script below into the Run AppleScript action.
    on run {date_string}
      tell application "Numbers"
      tell document 1
      tell active sheet
      try
      set crm_table to (item 1 of (every table whose name is "CRM"))
      on error
      display dialog "No CRM table in this sheet"
      return
      end try
      tell crm_table
      try
      set the_selection to selection range
      set the_row to row 1 of the_selection
      on error
      display dialog "Select some text in a cell"
      return
      end try
      set the_col to item 1 of (column of the_selection)
      set header_cell to cell 1 of the_col
      if value of header_cell is "Next action required" then my run_calendar(date_string)
      end tell
      end tell
      end tell
      end tell
    end run
    on run_calendar(date_string)
      try
      set date_string to date_string as string
      set real_date to date (date_string)
      on error
      set real_date to (current date)
      end try
      tell application "Calendar"
      activate
      switch view to day view
      try
      view calendar at real_date
      on error the_err
      display dialog the_err
      end try
      end tell
    end run_calendar
    Click the little hammer at the top to make sure that the script compiles (indents and colours in). If it doesn’t, you may need to sort out some line breaks in the copied and pasted script.
    Now save the workflow as Go to date in Calendar. Quit Automator.
    So what does the script do? Basically, it looks at the selected text in a Numbers cell and checks to see that the table name is “CRM” and the column header is “Next Action Required”. It then tries to convert the selected text into a valid date. If it can, it takes you to that date in Calendar. If it can’t, it takes you to today’s date. In both cases it switches Calendar to day view. You have to bear in mind that if you select all of “10/10/14 Call John re contract” it won’t understand that part of this is a date, and won’t go to October 10.  You'd have to select just "10/10/14"
    To run the Service, right-click or control-click on the selected text and go down to Services, then choose Go to date in Calendar:
    Alternatively, run it from Services in the main Numbers menu.
    You can set up a keyboard shortcut for any Service in System Preferences - Keyboard - Shortcuts. Post back if you need more info about this.
    Tested with Numbers 3.5 (2109). This will not work with Numbers '09.
    Hope this works for you, let us know how you get on.
