I can read two-channel USB-6008 using THE Signal Express?

Hello world!! Is possible to read the two analog inputs at the same time? Example: Using Signal Express, I need to read the (channel 0) analog input and analog input (channel 1) at the same time. I try this but, the signal on purpose gives me an erro

can you have set for the analog inputs points

If you install an analog input can you get set points that trigger an alarm or an engine that allows you to enable or disable

Different frequencies of signalexpress with oscilloscope

Hello I'm new to the signal processing. I am facing some difficulties to measure the signal of a sensor of acoustic emission for my project. I use the PXI-6115 module with 1042 q and terminal block is TB2708. I used AI0 and AI1 for main signal and tr

Can I have the user enter a variable that will be used to Signal Express?

We seek to use the Signal Express to collect data of analog sensors and load cells. We would like the user to be able to enter a variable that the program Express of Signal can act on. Is it possible within Signal Express?

Signal Express 2009 causing NIMAX generate an Exception error message

I have a system which gives an error message when I try to open an instrument in NIMAX. The popup error message shows 'unexpected error', with a code of "MAXKnownException. This system running Windows XP, and we Signal Express 3.0 with 4.3 NIMAX work

VISA LabWindows timeout exception

I use viWrite and viRead in LabWindows to fit a chain of command asking for the data to be written in a network by ethernet and read Analyzer results.  Once each occurrences hundreds the camera seems to get hooked on reading, what happens to expired.

Module MT FSK. VI, too slow: 5 seconds to generate a single waveform.

Hi guys RF OR,. I have problems of bigs with the module MT FSK waveform. I'm trying to generate RF signals, based on sending a stream of input bits to 544 bits with a rate of 8.8 KHz modulation, with a frequency of 15 KHZ deviation and the frequency

2.7 GHz vs 6 GHz... Differences of EVM

Guys HW RF NOR expensive, I have a 2.7 GHz DAMA, but also a 6 GHz DAMA... I see a huge difference in my readings of EVM with the even a Labview VI and had TO send a pre-defined package. I'm decoding my frames in the 2.4 GHz band. I get favorable resu

Questions about the frequency step response

Hello I use the Signal Express 3.0. I'm not clear on the transfer functions in step of frequency response with different modes of calculation of the average. What I got from the help file is this H (f) = Sab (f) /Saa (f) which is cross the frequencie

I can modulate the fsk and qpsk without modulation toolkit?

I develop didactic modules related to modulation fsk and qpsk for begineer students learning in labview, my question is: can I make VI involving fsk and qpsk modulations, but only using labview? I don't have the modulation toolkit and examples that I

Why cant a shared variable be read as a diagram in SignalExpress

In SignalExpress I add a step to read a shared variable. I can display it in graphical mode, but not the graphics mode. Can someone explain why this is? I'm doing something wrong? Kind regards Frank Greenslade Christchurch New Zealand

rate of multiplexing

Hello I use the Signal Express 3.0.  I used several data cables to connect the three channels. Sine wave signals with different sampling frequencies were sent to these channels. When I took a quick glance at her signas in the time domain and measuerd

How can I integrate IPS into the Sound and Vibration Assistant 6.0?

I found out how integrate time domain signals to m/s in S & V 6.0 Wizard, but not IPS.  I could scale the signal, but the axis labels will be wrong.  How can I integrate directly to the IPS of the entrance of G?  Also, is there a way to do the same t

Questions about an average of response spectrum and frequency of feeding mode.

Hello I have a few questions about an average of mode. When I generate a sinusoidal signal from one output to two input channels channel to see if my DAQ card works well and vector averaged in the power spectrum for DFT, the amplitudes was different

5142 channels

Hello My question is how to scan data using the channel 0 and channel 1 of a digitizer simultaneously. I did two files of VI for this race on 5142 channels 1 and 2 using two different anttenas, but when I run one another is arrested. or when I try 2

Use of NOR-9161 & 9215 in SE 2.5

I can collect data using NOR-DAQmx Base 2.2 using the foregoing and the recorder of data OR included, but so far have failed to help SE 2.5. Is it still possible? Thank you Randy

How to display the signal on a waveform graph in Labview Signal Express?

Hello I want to display a signal in Signal Express 3.0 in a "waveform table", but don't know how to do it and I think that it may be impossible? In Labview, there are two ways to view data, a 'waveform table' or a 'waveform graph. The great thing wit

NI 6552 Signal Express sampling rate

I'm generating multiple signals for Signal Express. When I run them, some work well and others not, in other words, for some changes in sampling rate signals! Thera are two options in Signal Express: 1. read file waveform 2 sampling rate. to manually

Filter warning and ascii except error

Hello I am the scene modal analysis using a hammer, the USB NI 9233 cRIO DAQ and the Sound and Vibration assistant. The steps were set in Signal on purpose as DAQ acquire-Trigger online-online-online-online FRF power spectrum filter => save in Ascii.

Spit when starting

Hello When I try to start my Signal Express 3.0, the splash screen just aFather for a second then windows will be to stop it. I m using Vista 32 bit
