Topic: ADC 11 much slower than Dr-DAQ in Lab View, Driver Problem?
Replies: 3
Views: 5950

Hi Hugo, The labview application will use all the processor time that it is given. If the OS (NT4) allows it to use 100% of the processor then it will do this. I will speak to the relevant department with regards to this problem. You can get the old driver off the CD which was sent with the ADC-11/1...

Hi Scott,

You can view the frequency response in the spectrum analyser, but you are not able to measure it.

The 200 series (ADC-212, ADC-216, ADC-200) all provide a signal generator.

Best regards,

Hi, The sampling rate for he ADC11 is 10ksps, however this is divided up between the active channels. The driver for the ADC-11 should not effect the speed of the application. If you require a faster sampling rate than you are getting from calling adc11_get_value() (approx 200µs to take one reading)...

Hi, To measure sound waves with the ADC-40 you will need a microphone connected which you will connect to a BNC. To source the BNC connector try: www.farnell.com. The microphone cables can be soldered onto the BNC. The microphone will recieve the noise and create a voltage. To generate higher voltag...

Hi, Unfortunately, we do not produce the sensors that you require to measure vibration or noise. You will have to source these from a third party, such as rs or farnell: www.rswww.com www.farnell.com To measure temperature you will need a signal conditioner that can use k type thermocouples... but a...

Hi, The ini file should be called TEST***.ini, where the *** indicates the international dialing code for your country. If you are using English this would be 044, for Germany 049 etc. Once you have defined your ini file this should be saved in the same directory as Picoscope was installed, for the ...

Replies: 1
Views: 5832

Hi, The ADC-100 would not be suitable for this application as the ADC-100 does not have any in built memory and thus when the PCs Processor gives time to other processes it will affect the Sprectrum Analysers display pattern. The unit which will meet the criteria is the ADC212/3, see specifications ...

Hi,

If you keep Picolog or Picoscope running all day do either of these crash on your PC? These use the same drivers that are provided in the driver downloads.

Check that the functions are being called in the correct order against our example programs.

Best regards,

Hi,

We were discussing the measurement of frequency here (not voltage). Our products have no minimum analogue bandwidth, therefore DC voltages can be measured, but the frequency of DC cannot be measured (pure DC is 0Hz anyway).

Hi, The function adc10_open_unit return value is not an indication of whether the ADC12 is connected, but if the parallel port can be opened. If the unit is not connected the value returned by adc10_get_value will always be 4096 adc counts, since it has a 12 bit resolution. If the full voltage range...

Hi, The EL005 datalogger does not have an external display, this is only available on the EL008 datalogger. The frequency that you sample at is dependant on the rate of change for the temperature. If the rate of change is slow then the sample interval can be lengthened ... but if the temperature can...
