Frequency minimum step length and duration list minimum for the frequency lists in the generator of signals from NI 5406

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.

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.

  • Connection of the PXI-4071 - can sound and LOs remain interconnected for the impedance of the cable 2, voltage DC/AC, frequency and waveform acquisition?

    Hello

    We use the DMM and SMU-6363 map to test a hardware device.  We will also use a PXI-2530 b switching matrix.  We will use the digital multimeter to perform the measurements of voltage, DC and AC, measurements of impedance (2-wire and 4-wire), frequency and waveform acquisition.  Can the PXI-4071 left be 4 wire connected (black jacks taken connected and red connected) mode and still be used to perform all other measures (including 2 impedance of the cable).  This would simplify the switch connections.

    Current measures use the son + and LO, but the HI and S-can remain connected.  The problem you are having is if you have an active device the digital multimeter and take you a 4-wire resistance and the measurement of voltage with all 4 wires connected and then change to a current... When you do this, short-circuit you the terminals of the DUT, on that you just take the measurement of the resistance.  If the terminal HAD, say, a power supply 10V, then you have just shorted out.  Of course, this isn't a problem if your Instrument is a passive device, or if you change just the unused two lead whenever there is an active device of low impedance.

    If you want to make voltage, current and 4-wire resistance, you need all 4 wires.  If you want to do the voltage and current, you will need 3 wires, but you could connect the s + Hi and then just do the two wires.  I vote running every 4 son to your DUT for maximum flexibility.

    2-wire resistance is a must if you are measuring resistance above 10 MOhm.  Alternatively, you can use 4-wire for all measures.

  • Aftermath - change slides duration to account for the different lengths of video/image

    HI - as you can tell I'm pretty new to Ae - I use programs like hearing and first every day from work but I've never used after effects. Asked me to create a showreel by using After Effects. Like most "newbies" I headed over to a stock site and downloaded the following model https://videohive.net/item/clean-media-slideshow/15003701

    It all seems simple drag and drop the media in each slide / edit text etc. BUT I noticed that /(comps?) slides appear to be of a fixed length - I was wondering if there is a way to change the "timing" of each of these slides to account for the different lengths of video/still (while keeping synchronized animations)? Any help would be much appreciated - here is a link to what I've done so far Craig Jackson - stuff more After Effects - put... | Facebook

    I know there are tutorials on here and on sites like Lynda - and I started to go through them - but any help would be amazing.

    Kind regards

    Craig.

    I see that it's much better now, thank you.

    Here's the problem with the models. To make them easy to customize, they are awful to customize. I know it's not supposed...

    They have complicated - sometimes more than necessary - which makes them easy to drop your own photos/videos. However, this means that if you REALLY want to change something, it's going to be quite complicated. I only buy templates if I want exactly what the model has. Otherwise, it's actually faster for me to build myself something. I have over a decade of experience with After Effects, so trust me on this, don't mess with the model. Without much more experience, he'll just be frustrating.

    What you can do, is switching to the video full screen. You need not stay in the template all the time. Put your video and images in the template, but there where you want it to be longer, put the beginning and ending in the model. Then, after you have made out of AE, go in first and just cut (or use a transition from light leak any) full screen video for executives, want to be longer. TADA!

  • Bytes of TCP IP and subset of bytes for the connection of server and clients

    Hello

    I have a problem on the server and the client connection using the TCP/IP protocol. In the client, I have 41 cases, 1 case of timeout, others are for the case of button when they are pressed and then the LED on the server will be to market and if a click again the led will be off. But when I reached cases 10, 11, 12 up to the 41 (key case), that the LED lights if you click only once, but when he double clicked then the light does not turn off. So, how you solve the problem? Is this subset or bytes to read because the first subset is 1 case but no 10 to 41 will not work, but I change the subset in 2 then the case works for don't light the LED, but it do not work to turn the LED off.

    I also download the vi in this for reference.

    the user name for the client is the user and the password is pass.

  • How to connect a scanner of network including the Windows 7 firewall is blocking and adding an exception for the associated program to access the scanned files has no effect?

    Hello

    I have recently upgraded to Windows 7 and the process for adding some of my old material has been an interesting question. Who made me stuck is to be able to access my network scanners "mailboxes shared" in order to recover my scans.

    The product in question is a large format Xerox 6204 printer/scanner. The installation process for the basic print server run the 6204 as a network printer went relatively smoothly and seems to work as expected. However, the problem arises when I want to use the functionality of scan of the 6204. Scans are stored in mailbox store ' ' on the 6204 and must be retrieved by a piece of software Xerox called "wide Format Scan Service. This program essentially connects to mailboxes mailbox via the IP address of the 6204 on the network and from there should allow me to download the scans on my Windows 7 computer. Unfortunately, in order to connect to the mailbox store I am currently disable the firewall of Windows 7 altogether.

    I tried to add the Service to Scan large Format to the list of allowed programs, which gives an "impossible to connect to 6204' error. I tried to add the program to inbound and outbound rules manually, even though my experience with this is limited, with the same error. So leave the default settings in the wizard, I also tried to use the technical netstat to find out what are the ports, the software used and adding them to specific ports in the properties of the rules - all without success.

    For now, I'm stuck the point of having to run my installation of Windows 7 without a firewall to use my scanner large format, which is obviously an undesirable situation. If anyone can offer help or advice on how I can solve this problem it would be greatly appreciated.
