(Agilent E3631A) Question about switching between channels

Hi!
I have got a problem with my Agilent E3631A. I want to control the machine into switching between +10V and -10V at given intervals of time. This should of course be achieved by switching between channel 2 and 3, but here the big problem arises: When the (+) and (-) are connected through the same wire, a current starts to pass from (-) to (+). I want to be able to completely close the channel that is not used a the time, thus making sure that the machine isn't short-circuiting the set up.
Does anyone know how to "seal off" a channel?

Hi Simon,
as far as I know the 3 outputs of the power supply are independent.
Have you tried to disable channel 3 through an SCPI command (or a driver VI) while enabling channel 2 and vice versa as you need it?
I thought if disabling an output this one is then completely cut off, maybe it helps.

A question about switching between streams

Hi,
I am using a set of streams and readers in the following format to read from an ascii / binary mixed file. Once i read past all the ascii I break out of the loop and then use the data input stream to read som four byte floats from the binary data.
If you look at the extract from the file that lase piece of ascii that I read in is EST_Header_End. It is then followed by the floats. I know that the .. following the EST_Header_End is carraige return and new line. My problem is that when i start reading the floats i get NaN even though i know for a fact that the values following the .. are floats.The second float that it read in is definitely 1.0 . I cannot understand why this is happening. Surely if i start using a DataInputStream it should start at the same position as the BufferedReader left off.
fis = new FileInputStream(fileName);
bis = new BufferedInputStream(fis);
//allow a reader from a stream
isr = new InputStreamReader(bis);
//read the raw bytes
dis = new DataInputStream(bis);
//read the characters and strings
br = new BufferedReader(isr);EXTRACT FROM FILE
Channel_10 lpc_N..
EST_Header_End..
<..@?...K...>..;>.P.>...>.S:>....4f....}...."=...>...<._@?...K{s.>...>.U.>.L6>..<>....5.....4..0...
for(int k = 0; k < numFrames; k++){
     System.out.println( "reading track" );
     voice.diphone[index].frame[k].setframeTime(dis.readFloat());
     counter += 4;
     System.out.println( "time " + voice.diphone[index].frame[k].getFrameTime());
     voice.diphone[index].frame[k].setIsVal(dis.readFloat());
     System.out.println("isVal "+ voice.diphone[index].frame[k].getIsVal());
     voice.diphone[index].frame[k].setGain(dis.readFloat());
     System.out.println("isVal "+ voice.diphone[index].frame[k].getGain());
     counter += 4;
     for(int l = 0; l < (numChannels); l++){
          voice.diphone[index].frame[k].setValueLpc((dis.readFloat()),l);
          counter += 4;
          System.out.println("LPC coefficents at diphone "+ index +" " +"frame "+ k+" Lpc coefficent "+l+" " + voice.diphone[index].frame[k].getValueLpc(l));
}

I assume that you read
EST_Header_End..
with the BufferedReader, using readLine().
The problem is that when doing the readLine() (or any read for that matter) using BufferedReader, it's going to read more data than it needs and store those bytes in the BufferedReaderClass. Then when DataInputStream goes to read, it will not know this and read somewhere down the stream.
Probably, as unpleasant as this is, you need to layer the DataInputStream on top of the BufferedReader. Or maybe you can do something fancy with mark() and reset() altho, doubtful.

How can I insert a code to switch between channels?

I’ve got a HP4263A LCR meter which is being used with an ER-18 device to get multiple channel data acquisition, when I go to getting started to trigger the device, but this VI do not have an icon to change the channel how can I insert a code to switch between channels?

I am just trying to use the drivers developed by NI for this device, but I don't know how to work on them to obtain data from three points, or three channels which I am using from an ER-16 device. So all what I have is the driver VI for the HP4263A.the only VI I can use is getting started, because whe I try to run any other one, this message appears:
Error -1073807346 occurred at VISA Write in HP4263A Self-Test.vi.
Possible reasons:

your help would be very helpful

Few questions about difference between Satellite P70 , L70, S70

Hello, i have many questions about the series P70 , L70, S70 that come with a 1920x1080 panel.
1) What are the differences between the L70 and S70 series? Except of the HDD capacity and RAM, the notebooks look pretty identical.
2) Do P70 , L70, S70 support a 2nd HDD or is it just the P70 series that support it ?
3) Do all three (P70, L70, S70 series) come with the same TFT Panels ?
4) Which of the above series supports mSata ?
5) Do all of the model of each series come with a mSata support? E.g. Could it be that L70-a-13m supports mSata while the L70-a-146 does not ?
6) All of the above, come with a S-ATA II or S-ATA III interface ?
7) Which is the best of those series listed ? I am trying to understand what makes the big difference from S70 to P70 except of the casing for example.
Thank you in advance.

>1) What are the differences between the L70 and S70 series? Except of the HDD capacity and RAM, the notebooks look pretty identical.
What Sat L70 and S70 models do you mean exactly? There are different L70-xxx and S70-xxx models on the market which supports different hardware specifications.
>2) Do P70 , L70, S70 support a 2nd HDD or is it just the P70 series that support it?
As you can see in this [Sat P70 HDD replacement document,|http://aps2.toshiba-tro.de/kb0/CRU3903II0000R01.htm] the P70 series supports 2nd HDD bay BUT even if there is an 2nd HDD bay this does not mean that you could use 2nd HDD. In case the 2nd HDD bay would be equipped with HDD connector, you could use the 2nd HDD
I found also the [Sat L70/S70 HDD replacement |http://aps2.toshiba-tro.de/kb0/CRU3703HG0000R01.htm] document on Toshiba page and there I can see that 2nd HDD bay is not available
> 3) Do all three (P70, L70, S70 series) come with the same TFT Panels?
See point 1). Different P70, L70, S70 models were equipped with different hardware parts.
> 4) Which of the above series supports mSata?
As far as I know only some P70 models are equipped with an 256GB mSATA-SSD.
> 5) Do all of the model of each series come with a mSata support? E.g. Could it be that L70-a-13m supports mSata while the L70-a-146 does not ?
See point 4) not all models supports the same hardware specifications
> 6) All of the above, come with a S-ATA II or S-ATA III interface ?
I dont think that SATA III is supported. I guess it would be SATA II
> 7) Which is the best of those series listed ? I am trying to understand what makes the big difference from S70 to P70 except of the casing for example.
Not easy to answer because there are too many models released in Europea.
And not all models are available in each country. So I guess you will need to look for models which were released in your country.

Basic questions about AirPort and channels

I have a VERY limited knowledge about networks. Please keep answers simple.
My setup is very basic. My computer is connected to the internet via AirPort through my wireless gateway (router).
When I pull down the AirPort menu from the toolbar it lists 3 network names plus Other. My network name is checked. Why are 2 others listed on my computer? They aren't listed in my AirPort Network System Preferences under Preferred Networks so I can't delete them.
I downloaded iStumbler to try to get more information. It lists all 3 names plus one more that comes on and off. My signal is over 100% and all the others are around 50%.
Also, three (including mine) are using channel 6 and one is using channel 1. Should I change my channel? Everyone always mentions 1, 6, and 11. Could I use 4 or 5? Are some channels stronger than others?
Thanks.

"...Why are 2 others listed on my computer?"
You have neighbors with wireless networks and you are getting a signal from them.
"They aren't listed in my AirPort Network System Preferences under Preferred Networks so I can't delete them."
You can't delete them because they are your neighbors signals.
"should I change my channel?"
I would switch to channel 9.

Question about switching videos.

Hello everyone!
I would like to make a video player with the ability to
switch between two different
video files with a keystroke. It must loop the file forever
until it reads the keystroke to switch.
How can i do that? Dont have great experience with flash, im
using flash cs3 on a mac.
If someone could point me somewhere or explain i would be
grateful.
Thanks in advance

lyons00,
The legality of copying DVDs to another format, sometimes called "ripping", is a murky area legally, and outside the Terms of Use for Apple Discussions. Essentially when your purchase a movie, your purchase a license to play it at home on a DVD player. Playing it in front of an audience, or changing the format of it require a different license from whomever holds the distribution rights.
Thank you,

Question about switching from pc to mac

I am going to be purchasing a new computer in March. I am seriously considering switching to a mac. I've owned a mac before and I obviously have my reasons for wanting to go back...however...I've always been a pc and all of my software is pc based...and a lot of them I no longer have the install discs for. I'm a designer and my main concern is losing the ability to use my software, such as Adobe CS4 because I dont' know if it will be compatible with the mac. My question is, is there a way to transfer my software from my pc to a mac without any external hard drives and without having to buy all new software for the new mac? This is going to be the deciding factor on whether or not I go with a mac instead of a new pc. I really could use some input on this. Thanks so much.

If you've bought your Mac, be sure to exchange your Windows CS4 license before CS5 comes out. Adobe will only do a cross-platform swap on the current version (which I found out the hard way!)
Take a look here: http://kb2.adobe.com/cps/405/kb405819.html
I have heard of a lot of folks having trouble getting a cross-platform swap. Also, don't believe anything an Adobe customer support rep tells you. They are either "misinformed" or they flat-out lie.
Best of luck!

Question about BT Freeview channels

I am trying to set up my BT Vision box with a TV that's from India which does not have a scart socket. Hence I bought a scart to AV converter cable so that I could use my TV. Now the setup is complete, however nothing seems to work. Below is what happens:
When I use the BT vision remote control (black remote and black vision box) it does not seem to affect my TV at all, meaning my TV does not respond to the remote signals.
When I first turned on the TV and Vision box I never got to see the BT welcome screen or instructions screen to scan thru the free view channels.
I can see 4 channels when the vision box is disconnected and aeriel cable is directly connected to the TV
Is that a must to have an aerial or antena to watch free view channels with BT Vision?
I am totally confused. Please guide me thru.
Thanks,
L

Yes you MUST have the box connected to an aerial in order to receive freeview.

Question about switching DPS accounts and In-App Purchases

Here comes a tricky one
I have my app published on Apple using an specific DPS account (aka [email protected]) and I have some in-app purchases into the app that the final users have already bought.
For some reason, I need to switch the app to use a different DPS account (let's say [email protected]) and I need to recompile the app and make it available on App Store (Apple Account will be the same one). Concerning the folios, I can upload them again with the same product ID as the older ones and delete the older folios from the older account.
Question is: What would happen to my In-App Purchases? Will I be able to restore my purchases if I have a new app with a different account? Will Adobe allow to use the same Product ID for another folio even if it was used previously?
Hope you can help me out with this.

Phone is now fixed and because the game was saved to my game centre, it loaded with all purchases. So I'm thinking that as long as the game is saved to game centre, it will reload as it was previously.

Newbie question about switch statement

Lets say you have a loop and inside the loop you have a switch statement, how do you BREAK out of the outer loop?
for (i=0....) {
switch {
case 11:
.... some stuff
break; <==== HOW DO I BREAK OUT OF THE for loop here?

In standard C and standard C++ the break statement terminates the nearest enclosing loop and only that loop; i.e. control transfers to the first statement following the loop. I think there are C or C++ extensions that allow loop tags which may be used with a break to specify which loop to drop through, but I don't think these are supported by gcc, and they would certainly be very non-portable.
There are several common ways to drop out of one or more outer loops. In many cases, there's nothing else in the loop following the switch so you can simply write
switch (condition) {
default:
case 0:
break;
// other case statements here
break;
Else you can declare a loop control var and use the continue statement like this:
for (i=0; i<jMax && !bDone; i++) {
switch (condition) {
default:
case 0:
bDone++; continue;
// other case statements
If you need to escape several loops and/or don't want to use loop control vars, you might consider structuring the code so you can use return to terminate the entire function. In the worst case of a very complex structure that you don't know how to simplify with a helper function, you can always resort to a goto:
switch (condition) {
default:
case 0:
goto escape;
// other case statements here
// remainder of code inside nested loops here
escape: <first statement following the outermost loop>;
Note that the statement following the escape label is always executed; i.e. when execution skips the goto it's as if the statement following escape was unlabeled. Use goto sparingly of course, since it's an artifact of unstructured programming. But when you really need a goto, it can make your code much easier to maintain.

Question about "switch" statement

hi all I am new to Java programming..
I have one problem that is
I would like to use switch statement like below
in the switch statement can we use only integers ?
but i am using string it is not supporting ..
for strings like below what I have to do...
String temp = "str2";
switch(temp){
case "str1":
case "str2":
case "str3":
case "str4":
please send the solution if anyone knows
thanks

What do you mean by a smart hash?At least smarter than String.hashCode ().
Don't think so - char, byte, short, or int.You're correct - seems I've got to test things before I post. So it's safe to say that a switch works on anything that can be treated as an int?

Question about transfer between oracle and sql server

Could i program to transfer lots of data between Oracle and SQL Server quickly?
I have tried make two connection between two databases, but it took me lots of time to transfer data.
How could I do it?
Thanks

Hi,
If you need to move data fast, then use the Oracle Migration Workbench to Generate SQL Server BCP data extraction scripts and Oracle SQL Loader files.
This is the fastest way to migrate the data.
In the Oracle Model UI tab of the Oracle Migration Workbench, right mouse click on the tables folder. there is a menu option to 'Generate SQL Loader ...' scripts. This will help you migrate your data efficiently.
