• Why left outer join with a table gives me more lines?

  Hi gurus,

  I can see "view_a" and a table 'table_a '.

  view_a a county of 100 lines. Now, when I left outer join that discovers with a 'table_a', I expect all 100 lines.

  However, I'm more than 100 lines. Is it still possible?

  Also even to analyze these situations, how can I move forward?

  Because it is very high volumn of sight and takes longer to run.

  Select count (*) view_a, view_b

  where view_a.col1 = view_b.col1 (+)

  and view_a.col2 = view_b.col2 (+);

  Thank you

  Just join of two tables in general will give you more rows of one table has.

  Scott DEPT table contains ONE row for deptno = 10

  The EMP table has THREE rows of deptno = 10

  The number of rows you plan if you join two tables using an equi-join?

  Three - what is MORE lines the DEPT table has for deptno = 10

  Select * from Department where deptno = 10

  DEPTNO, DNAME, LOC
  10, ACCOUNTING, NEW YORK

  Select * from emp where deptno = 10

  MGR, EMPLOYMENT ENAME, EMPNO, HIREDATE, SAL, COMM, DEPTNO
  7782, CLARK, MANAGER, 7839, 6/9/1981,2450, 10
  7839, KING, PRESIDENT, 17 NOVEMBER 00, 10
  7934, MILLER, CLERK, 7782, 23 JANUARY 00: 10

  Select dept.*, emp.*
  Department, emp
  where dept.deptno = 10
  and dept.deptno = emp.deptno

  DEPTNO, DNAME, LOC, EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO_1
  10, ACCOUNTING, NEW YORK, 7782, CLARK, MANAGER, 7839, 6/9/1981,2450, 10
  10, ACCOUNTING, NEW YORK, 7839, KING, PRESIDENT, 17 NOVEMBER 00, 10
  10, ACCOUNTING, NEW YORK, 7934, MILLER, CLERK, 7782, 23 JANUARY 00: 10

  So if these are the lines ONLY in the table EMP and DEPT the query would give you THREE lines despite the DEPT table only ONE line.

  No do you expect? You get ALL the child rows that belong to the parent company. Otherwise, how could it possibly work?

  The OUTER join includes lines where the parent row exists but there is NO child line as others have shown.

  Outer joins

  Outer join extends the result of a simple join. Outer join returns all rows that satisfy the join condition and also returns some or all rows in a table for which no line of the other meet the join condition.

  Get more lines to exist in one of the paintings is a basic necessity. It usually has NOTHING to with the question of whether you have an outside to join or not.

• Wait signal generator complete the scan list before sending the next command

  I am writing a program for Agilent E4421B signal generator scan to list between a range of frequencies (ramp up to the maximum frequency and then back down to the original frequency) specified. The signal generator has only a list of 401 points, which is a problem when I want to wash over a wide frequency range. To work around this problem, I would like to perform several scans of list in a row. However, I can't figure out an effective way to "say" the program to wait until the previous scan has finished before sending a new order of scanning for the signal generator. Any ideas? For reference, I use Agilent ESG drivers series LabVIEW.

  Thank you!

  If you use standard VISA calls, I would say just that send the scan command, but add; * mutual fund? (operation ends?) make a query.  Then, run a VISA to read what's coming.  This indicates to the device to send a 1 to the output buffer when the scan is complete (or just about any other operation, also).  As you are waiting for a response, your computer will wait the amount of time to wait so he could see a response, it is not less, your way with the exact amount of time - no more - to be actually taken.

  A few warnings:

  (1) make sure that the time-out is longer than the length of most slow scan.

  (2) there are variants of the '1' being returned.  I saw '1', '01', and even "1.00E + 3" therefore to allocate more than one byte to read."

• calibration of Agilent N5183 Signal generator for specific output level

  Hello

  Newbie to labview environment!  I'm writing a VI to calibrate Agilent N5183 to a specific output.  For example if I want to have-4.5 dBm output of my installation (as stated on my electricity meter) I'll have to set the sig gen to say 7 dBm given my losses, etc.

  How can pointers, I start to weld it?  I think I'll have to create a while loop to check the levels of power, but I don't know how to increment and decrement the amplitude of sig gen and stop at the desired level!

  Thanks in advance for any help.

  PS: With the help of Labview 2013, on win XP!

  3. adjust the pout to sign Gen to the desired level, while controlling the power power meter

  Why is it that step at all?  It is not clear from your description, what makes the difference between the reading of the gauge and the output level of the sigGen parameter.

  I have done many times.  Especially in the RF field, you want your tests to have a certain level of power to the object to be measured.  We therefore have to adjust your signal generator to compensate losses in cables, couplers, etc.

  To do this, all you have to do is set your generator to the desired level.  Then measure with the power meter.  Subtract the measurement of the desired and add that much more to the output.  Repeat if necessary.  I advise to use a conditional TO the loop so that you can easily set a limit to how many times adjust you (I've been in infinite loops due to the weird situations here).

• Several colors of background on a GOLD-table fill to draw graphical point * behind * the grid lines

  I have some a matter of aesthetics.

  I wrote a program that displays data for binary files. These binaries have blocks of data, an hour or two. Each piece is a playback window, and there are a handful of reading windows per day.

  The data view is in effect, what I'm working on now is a more intuitive way to choose what data should be displayed.

  My goal is to have a graph of waveform with the X axis represents a day full (0 - hr 24 hr) and is indicated on the chart what time windows are available for review, that is, data have been collected. The background of a "collected" window will be yellow (or another color), while times in the course of which no given is collected will be black. The user will then drag the sliders to select the window of what he or she wants to see the data.

  It was quite easy to achieve by drawing the curve a digital signal (1 for data collected during this period, 0 for no) and point-fill with yellow to zero. My only problem with this solution is that filling point appears on the lines of the grid, that does not look quite right.

  Y at - it an easy way to get the grid to appear at the top of the charts, or is there a way to programmatically set multiple background colors (it could do the same thing)?

  Use the property "draw pictures" and draw your own grid before image.

• With the help of the external RF signal generator

  Hello.

  I just want to ask how can I remove the frequency shift if I use an external RF signal generator (instead of the RF PXI-5652 signal generator module). I understand that in the case using the OR to generate RF signals, frequency shift is deleted by setting the same source of reference for the transmitter and the receiver clock (placing the clock source of reference to PXI_CLK of the façade of generation VI and VI of the acquisition).

  Thank you very much.

  Hi Betty,.

  In this case, no changes are needed, such as modules OR still use background clock basket PXI as the ref. clock source If you are still having a frequency shift, you probably need to configure sig gen to lock a clock external REF. Usually, just make the connection of the signal is not enough - you must also indicate the sig gen to use the signal connected to the input clock ref. Terminal

  If you use the sig gen as clock source master Réf, connecting the 10 MHz of the gen of GIS at the BNC 10 MHz IN on the back of the PXI chassis replaces the clock native from the newly connected with the PXI chassis backplane, and analyzers are still using the clock background basket PXI as the source clock Ref (no change to the SW settings).

• Output a TTL HIGH 10 usec via the PFI port on AWG signal generator

  LV dear community,

  I want my signal generator (PXI-5422) to produce a pulse of 10usec with its PFI1 range each time that a wave of exit CH0.  The frequency of repetition of the CH0 impulses and the port of PFI1 is 10 kHz.  Is it possible for the signal generator automatically generate this HIGH TTL signals for usec 10 on the PFI1 line all at the same time produce a long-wave 100 usec?

  Another approach, that I'm considering is to re - route a pulse of RTSI1 (10usec) from an FPGA and output via port PFF1 of the GTS. However, I doubt that this is possible, as the HELP MENU for the working group said that the report can only occur when the Working Group is in "idle" mode.

  Any help will be greatly appreciated!

  Have a nice day I have attached a diagram of operation that hopefully, explains what I'm trying to do a little better.  Once again thanks for looking!

  Hi Denn_Mann,

  To get around the limit of 320ns, you should be able to use scripts with the FGEN markers to achieve your goal. Anything you want to do is use of script with markers in alternating mode. You may want to toggle high then low rocker after the number of samples you want pulse is high while your signal is present. I've linked some information below that should be good resources for script for you if you are not familiar.

• How to generate a pulse with the signal generator?

  Hello

  I would like to ask if anyone knows how to use the Elvis platform to generate a regulated pulse wave?

  

  It should look roughly like the picture above. A sine wave with the regulation.

  Anyone who can answer my question please respond to my post.

  Thank you.

  You are using LabVIEW to generate the waveform or using the Soft front panels? In LabVIEW, you can use the express VI generator function and specify the Type as "Sine". Then, simply change the amplitude of the sine wave. During the actual pulse, the amplitude would be what you want (i.e. 1 V) and while the pulse is idle, set the amplitude to 0.

  

  If you use the soft front panels, you can use the Waveform Editor to create a waveform that includes a sine wave for the length of your pulse and then the values of '0' for the rest of the time. Then use this waveform in the flexible front of the arbitrary signal generator. Simply create a component of sine as the first part of the wave and then add another element to a level DC '0' for the rest.

  

• [FPGA] Problem with the sinusoidal signal generator

  Hello!

  At first I want to apologize for my English is not my mother tongue.

  Hardware and software I use is:

  LabVIEW 8.5

  NEITHER RIO 2.4.1

  NEITHER cRIO-9014 (controller in time real CompactRIO)

  NEITHER cRIO-9104 (chassis and FPGA)

  NEITHER 9264 (16 channels, +-10V, 16-bit voltage analogue output Module)

  I made a very simple FPGA VI: a while loop, generator of sinusoidal signal and a FPGA of e/s node in the loop. I've specified the Gnerator settings by following the path:

  Frequency = 50 Hz
  Amplitude = 1
  Phase shift = 0.00
  Size of the table look-up = 1024
  = 16-bit amplitude resolution

  FPGA clock frequency (40 MHz)

  But the wave of "sine" I got is not what I wanted to get. First of all, its amplitude is 1 V. shouldn't it be coded on 16 bits? If I wanted to get 1V I should have specified Amplitude as a 3277. In addition, 'sine' is not very detailed, it's look like "steps", as many samples vere missing. What I did wrong? I checked the samples and tutorials, I did everything the same way. A I forgot something or not has not specify other parameters?

  Thanks a lot for your help!

  OK, I solved a problem. It's embarrassing to admit, but maybe this will help someone else I blame my inexperience

  The main solution to the problem was changing calibration of calibrated RAW Mode. After that, everythoing works as expected. I had a problem with a sample because I was using a multiplier to control the generated sine wave amplitude. But... She was set to 1 in the sinusoidal signal generator. That was the reason for waveform Gradin. Please, don't laugh too much

  In any case, thank you for an answer! It is now resolved

• Application of a policy of VSG when the vector signal generator is offline?

  How policies are applied when a vector signal generator is offline, make port profiles with an attached policy start VSG to abandon all traffic until the vector signal generator comes back online?

  VPath and vServices configuration

  http://www.Cisco.com/en/us/docs/switches/Datacenter/VSG/SW/4_2_1_VSG_1_4_1/vpath_vservices/reference/guide/vpath_vservices_config.html

  The default value of failmode is close.

  Fail mode specifies the behavior when the MEC has no connectivity to the service node. The default fail mode for ASA 1000V and VSG is narrow, which means that the packets will be dropped. The default failure of vWAAS mode is open, which means that the packets will be passed. service nodes vPath 1.0 does not support service chaining. When you use a vPath 1.0 service node in a string, traffic to that node goes into failure.
