  Hello everyone...

  I hope you could help me.

  SURVEY:

  I have a macro code, but there is no output from the image displayed in the specified activedso object after successfully connected to the specified IP address.

  I think that there is a problem by specifying the activedso object.

  THE MACRO CODE:

  Private Sub CommandButton1_Click()

  Dim o As Object
  As Boolean Dim success

  Set o = CreateObject ("LeCroy.ActiveDSOCtrl.1")
  ipadd = ActiveSheet.Range ("B1"). Value ' in a specific cell ip address value

  With ActiveSheet.OLEObjects ("ActiveDSO1")
  success = o.MakeConnection ("IP:" & ipadd) ' if the true value, capture the current image of the osci waveform digital lecroy and displayed in the object activedso
  If (success = False) then

• How do I capture the output of voltage full bridge with Signal Express NI9219

  Hello.  I'm trying to do and calibrate a load cell with the installation of full-bridge strain gage.  I use a NI9219 module with a cDAQ chassis.  Is it possible to capture the actual output voltage?  Signal Express gives me a value of strain, but I really need to know the output voltage.  Where to look.  I need only two channels for full-bridge.  I think that could connect the wires to the two remaining channels and read the output voltage of the strain gauges which would be connected as a tension of the 9219 entry, but I think that Signal Express could give me the voltage and output voltage directly.  Any input would be appreciated. Thank you!  P.S. I only use this equipment on occasion and am not the more familiar with it, so keep things simple for me.  Thanks again.

  Hi jgh@AET,

  The NI 9219 measures the ratio of voltage full bridge in hardware sensors, allowing any variation of the voltage to cancel. You won't be able to measure the output voltage of the sensor regardless of the voltage without additional channels, but you can measure the ratio of raw tension using the type of Bridge (V/V) . You can also use the type of measure of Force (bridge) measurement of load cell with engineering units (N, lb, kgf, no strain).

  This screenshot shows where the two Bridge (V/V) and Force (bridge) can be selected in the DAQ Assistant:

  

  These types of measurement were added sometimes around DAQmx 9.1, so if you have an older version of NOR-DAQmx, your DAQ Assistant maybe not them. The latest version is currently 9.4 of NOR-DAQmx. Front of NOR-DAQmx 9.1, the approach to recommend to measure the load cells was to use the custom with Excitation voltage type and a custom scale. However, Tension Custom excitedly can't Bridge of calibration in the DAQ Assistant.

• It is possible to capture the lines of delete with the CHECK feature operations?

  10.2 using triggers I can connect the deleted lines, but is it possible to capture the lines of delete with the CHECK feature operations?
  
  Thank you.

  You can find Fine grain auditing and capture strategy audit records (for example, access to a column), and also capture the SQL text.

  But that still won't 'copy' on all lines accessed by the user who runs the verified order (for example a DELETION).
  If you want to "save a copy" of the row that has been deleted by a user, you would still have to write your own trigger ON DELETE.

• Capture AbstractActionItem SIGNAL to slip into the menu drop-down

  Hello

  So I need to do anything when I press the ActionItem in slide it towards the bottom of the context menu on BB10.

  I created the shot on the menu drop-down

      Menu *menu = Menu::create();
      Image infoIcon = Image(QUrl("asset:///images/info"));
      menu->addAction(ActionItem::create().title("Info").image(infoIcon));
      menu->setObjectName("infoItem");
  

  Looked at the docs. AbstractActionItem

  https://developer.BlackBerry.com/Cascades/reference/bb__cascades__abstractactionitem.html the action point emits a triggered() Signal.

  Then ran info a bunch of question that did not help.

  • Looked QTDocs
  • Looked at the signals & Slots section of BB stunts Docs

  in my App.hpp file I added

  public:
     void debugText();
  

  I tried to connect the menu by using the following code:

  connect(menu->objectName(), SIGNAL(triggered()), this, SLOT(debugText()));
  

  It does not work, and I spent 2 hours trying to figure why not.
  How do you connect in fact these things?

  Thank you!

  Hello

  trigger signal is attached to ActionItem itself and not Menu object.

  And don't forget the Q_SLOT macro.

• ConfigFree does not show the intensity of the signal

  ConfigFree works properly - except that the Wifi strength is displayed at the highest level for all sources, regardless of how effective. (as it is deducted from the source location and the signal strength indicated by the utility windows)
  I.e. all access points are on the inner ring.

  I am running Vista on a Portege M400 with Configfree version 7.0.0.24 and Intel 3945abg driver 11.1.0.86. I got the Intel proset utility loaded, but they would not show the signal strength at all. So I unloaded it.

  I tried rolling back the drivers for the driver Wifi and Configfree with no change in behavior.

  Any suggestions at all would be welcome.

  Rod Laird Australia

  Hello Rod

  I use Vista on my Satellite last Vista designed ConfigFree utility, but I never noticed the signal WIFI is displayed there. Can you please explain exactly where this signal must be shown?

  When connected to WIFI, you can see the small symbol in the task bar but this symbol belongs to Vista and the symbol of the strength of the signal is also visible in Vista network and sharing Center.

  Sorry but I do not see this symbol in Configfree directly. When my laptop is connected to WIFI all I see in ConfigFree is connected (blue) status and the connection between PC icon and black (marked as G) WLAN. It is also interesting that the small blue animation moves along that black line.

• I have an SMU-5672 and capture the baseband on an oscilloscope. Can I do this?

  I have a generator of signals Vectoriels SMU-5672 and to capture the baseband with a reach to compare synchronization with my receiver (HAD).  I would like to connect a scope to the SMU-5442, but don't know if that problem.  Of course, I am particularly concerned by damaging the material.  This method would be the ideal way to check my timing of answer, but if you can't, I'm open to other suggestions.

  Yes, you can do it.  The device driver 5672 configures the 5442 for use is the direct path.  Direct tension max is 1 Vpp into 50 Ohm, 2 Vpp scope in high impedance, so make sure that your scope is put in place for this.

  Continue to use the 5672 as usual, but with your scope related to the CH 5442 0 output.  Assuming that the scope leads his entry (should not), there is no concern damaging the 5610 or 5442 by doing this.

  Unless split you the signal (not what I say), you won't get a signal off the 5610.  It is not clear how you planned to compare the signal for synchronization with your DUT.  No signal can be OK if you compare the time vs a trigger digital, may be exported from the 5442.  Be aware, however, that IF IN addition to RF Out 5610 is about 1.2 US.

  Also note that if you set NIRFSG_ATTR_COMPENSATE_FOR_FILTER_GROUP_DELAY to true, and a marker on sample output 0 event, event marker will be delayed to address delays in the processing of signal in the 5442 and delay analogue 5610, causing the marker event should be harmonized with the time "sample 0" appears on the RF Out 5610.  This attribute was added after the original version and the default values to false to preserve backward compatibility.

  If you are looking to compare calendar, setting the true Compensate for filter Group delay is actually what I would do rather than split the signal IF Out 5442.  You can check how much are aligned by tuning the 5672 at a fairly low frequency for your bezel measure.  5610 late is dominated by the IF filter, which is independent of the RF frequency.

• SMU-6556 - how to control the rise in digital lines (hsdio) time

  Hello

  Is it possible to control the rise in digital lines SMU-6556 time?

  Even in a low frequency 10 kHz signal rise time is 2ns.

  TKS,

  Hello engfpe,

  The SMU-6556 is a 50 Ohm system, which means that the output is source series finished to be 50 Ohms and all our cables and accessories are 50 Ohms.  With this configuration, regardless of the flow of data, you should have a clean edge up or down, regardless of the data rate. The quality of the production (edge up or down) on your device is related to the adaptation of impedance of your cables.

  The SMU-6556 cannot adjust the speed of scanning by itself.  However, you can insert simple passive components to do it for you.  I have attached below the images.  The first is a diagram showing a way to slow down the edge.  The second is the a waveform simulation showing the rate of original edge before it slows down and the edge of idle.   This simulation is not the SMU-6556 but rather a generic digital output for concept.  In the schema that R1 is set on 34 Ohms because U1.8 has the 16 additional Ohms on the inside.  TL1 is the output of 50 ohms simulating the cable on the SMU-6556.  R2, R3, and C1 are components, you can insert after the SMU-6556 twist before moving your device/cable.  In this configuration from cable to your device is TL2 which is also 50 ohm, but it could be another impedance in which case you would change R3 to match.

  You can see in the attached images, you can slow down significantly the edge with this configuration by altering the C1.  I hope this helps.

• Digitization and adaptation of impedance of the signal source entries

  I'm trying to measure the voltage difference and the time between the two entrances of a USB-5132 digitizer. The switching interval that I try to capture is ~ 150uS and I intend to acquire ~ 25K samples (50MS/s for 500, although it is an overdose of sampling frequency). The digitizer is 1 M ohms entered and I wanted to use the 100 SMA 50 ohm cables to connect to the source of the signals which in addition to several kohm impedance. My knowledge of RF is low and I am concerned about the impedance matching between the digitizer inputs, impedance source and wiring. What kind of considerations to I need to avoid degrading the signal? The switching signal is pulse-like and is rich in harmonics and on a sample of 500K samples/s scope is represented accurately. Should what kind of considerations I do about the impedance?

  Hi William,.

  There will be some problems if you try to use a source that has an impedance of several kohms. You will probably get the reflections of signals. What is the source of your signal has several kohm impedance?  I'd take a peek through the following article Developer area that describes some of the considerations when it comes from impedance matching. Specifically, I would check the last section corresponding resistive. This should give you a better idea of what to worry about your application.

• filter the peaks on the signal from ECG pulse!, help!

  Hello

  I have RCV of the ECG signal. I filtered the ECG signal and get the resource (interval between each pulse of ECG) records.

  

  The source of the signal have noise I use a threshold but sometimes spikes of failure. Like the previous capture. Normally, if you get a pic of fault detected, I'll try to find this index to add to the left or right of the peak, normally I add to the lower value. This works if it has only a bad impulse between 2 good.

  The problem come when I have more than a ridge between the two coupons.

  Also, when the impulse of R a loss threshold I have trying to find the index and get 2 new reading making division 2 peak value.

  I have attached the method I've used to adapt it. I only works if I have 1 Ridge added on real measures of R or pulse 1 loss R, when I have several pics no work.

  I would like to hear an idea to make it work better. I don't like the idea of removing the value interval, I have 2 hours of reading and if I remove the values I have lower data outoput is why I tried to summarize or division of values to get the correct reading without losing any data.

  Perhaps, there is any better filter for ECG of entry, so I have a R-own pulse and less noise between ECG pulses.

  Any advice is welcome.

  Best regards, Fred.

  Almost.  in the last step, you have extracted the real part of the complex waveform.  Instead, you must retrieve the extent.

  

  BTW, this idea isn't mine.  I got from this article

• low Harmonic frequencies in the signal strength

  Hi all

  I try to know what are the causes of noise in my signal, whether it's a faulty hardware or my lack of knowledge.

  The system that I'm actually consist of two engines not to not (parker HV232) that provide the uprising due to frost harmonic + pitch motion with phase shift of 90 degrees (a kind of movement of fish tail beat). I have a load cell 3 - axes attached to the shaft of the motor, pitch, and it measures up, drag and torque on a plateau which oscillates in the tunnel water (oscillation is provided by these two Steps). Tunnel to provide the incoming stream.

  Signals of strength are captured through SG-23 + PXI-6221 daq card, I put the gain on the last of them to +/-200 mV for better resolution.

  When the engines are turned off, the noise level on the static signal is the threshold of resolution, and nothing strange is not shown in the signal, and its ghosts.

  The problems begin when I initialize the motion on the steppers, FFT of the watch signal of the low frequency spikes that are exact multiplies the frequency of oscillation, I have attached a PDF for example.

  Disengage amplifier/filter which was suggested by manufacturing, and suspect I have observed could be due to this I'm not sure at 100%. The VI I use filter band-pass data in the 0.2 to 6 Hz, but somehow I can still see noise beyond 6 Hz.

  I was wandering perhaps someone has experience with similar issues and can suggest a solution on how to get rid of these harmonics.

  Thanks in advance

  I'm not an expert in the dynamics of the tunnel, but from what you say, it looks like they can't be noise but components generated due to the rotation of a mechanical Assembly. Normally people refer to these harmonics in the form of 'order', which means that they are a multiple of the frequency of rotation.

  So maybe it's the attacker

  1. check by an expert (the one that includes the mechanical system that you are using) that to the point where you measure the force will not get the components of the order.

  2. understand what exactly is the measurand. What exactly do you want to do with the measured signal (RMS, FFT etc..) Then you will be able to figureout if components of the order may affect your measurement.

  During filtration, the attenuation in the band determines how fast the signals will be thinning of the hard shoulder.

• Distortion of the signal caused by the channels # sampled and sampling frequency

  I am using an acquisition of data USB-6211 (250 ksps / s) and looking at the sample channels 3s 80kS. (Labview 2012)

  When I taste one channel, it looks fine (1 Channel_Sampled First_250kS), but when I add another channel to be sampled, the signal is driven down and that it depends on which channel is sampled (2 channels (Different) _Sampled First_40kS and 2 Channels_Sampled First_30kS).  Addition of channel 3, it pulls down even more.  I also noticed that the sampling rate also distorts the signal the higher the sampling rate, the more the signal is driven down.

  The acquisition of data IS sampling of signals "correctly" when I run my Labview VI my external hardware begins to read in correctly based on the distortion of the signal.

  What is the cause and is there a way to fix this?

  I have attached the waveform above captures and can post some if necessary.

  Thanks in advance,

  WBrenneman

  That's exactly what ghosts means.  The measurement signals later is affected by other signals.  It happens usually if you have a high impedance input signal.  Adding pads like you can help solve this problem by making the signal to a lower impedance.

  Ghosting would probably look worse to the frequency sampling rates higher, just as you said that you had problems, as it provides less time between samples of the amplifier set new voltage level when the multiplexer allows to switch between input signals.
