Re: Spectrum Recorder PCI-E Card?

Well, yes I thought it would require 100 or maybe even 1000 samples to disassemble a multiple signal voltage amplitude (of 20 ns in this case) into its originals properly . This is to some degree also a statistical/ mathematical question I have not researched fully, this time. However I can say, the...

Re: Spectrum Recorder PCI-E Card?

I see,measurement technology is unbelievable expensive in comprehension to other electronic equipment. Maybe I could use some nerd raw data acqusition equipment like a software defined radio . The features of the offered software defined radio are: 1 MHz to 6 GHz operating frequency up to 20 million...

Re: Spectrum Recorder PCI-E Card?

Yes. That's exactly the inaccuracy problem. A multi-channel-analyzer for a scintillator (consisting out of a transformation crystall and a photo multiplier tube inside) counts each bandwith of volt amplitudes (e.g. 10,5 mV - 11,5 V) separatly. Each amplitude corresponds to a certain energy of a part...

Re: Spectrum Recorder PCI-E Card?

Thanks Chris. As you gave me the right key words, I did another Ebay search now: (A/D, data-acquisition) (card, board) (PCIe, PCI-E, PCI-Express) @ Ebay However, I did not find a 16 bit 5GSample Card in the range of 1000 USD. So, how about a forum maker project "Spectrum Recorder PCI-E Card"? ;-) I ...

Spectrum Recorder PCI-E Card?

In the thread " Integrated Lab Measuring and Controlling (Labview, Labjack, ...) " we have already figured out, that high-frequency analysis is pretty costly. For cost effectiveness I am interested in recording only (without any analyzing features) of a raw high-frequency signal from a scintillation...

Re: Integrated Lab Measuring and Controlling (Labview, Labjack, ...)

Ok, I still owe you a summarizing synopsis, which comes now. I guess, it will contain some errors (as I am terribly stupid ;-)). Integrated lab measuring consists out of Measuring Generally future-proof realtime measuring requires: A standardized communication interface to the peripheral meter (e.g....

Re: Integrated Lab Measuring and Controlling (Labview, Labjack, ...)

Richard, if these guys eventually provided a 1 Ghz, 16 bit, 5 GSample/s and 1 TSample buffer oscilloscope for 500 USD, it would truly be about time synchronisation, only. But for now, as the effective measured time period of recent oscilloscopes is unbelievable small (due to small buffer size), it i...

Re: Integrated Lab Measuring and Controlling (Labview, Labjack, ...)

Very interesting. I just did a quick Ebay research. New 200 MHZ oscilloscopes with Ethernet-Port roughly start at 1500 USD . That's more or less for the deep pocket. On the other hand 2-Channel 200MHZ oscilloscopes with SD-card slot start at 330 USD. (Do not say, that the low price segment is good q...

Re: Integrated Lab Measuring and Controlling (Labview, Labjack, ...)

Thanks Chris. Ok. I have understood now, that USB is in some directions pretty suboptimal for future-proof PC based high frequency measuring. On the other hand serial port (aka RS-232) and parallel port (aka GPIB or IEC-625-Bus) are too slow to measure high frequency (> 3 MHZ) directly. And the meas...

Re: Integrated Lab Measuring and Controlling (Labview, Labjack, ...)

To let me get this straight what you have said: I thought, there are two levels of drivers: A lower level USB port driver between the OS and the USB port controller chip (hardware on the mainboard) A higher level driver between the OS (or the application) and the periphal hardware - e.g. a scope - (...
