Analog-Digital
Conversion Card for PCI Bus-n20-12PCI
Application
Analog-digital conversion; high sampling rate; 2 synchronous
channels.
This card is widely used for building systems of radiolocation.
As any data-capture card it is a universal measuring device. An
oscilloscope a voltmeter a spectrum analyzer and a capturer (registrator)
of quick processes can be designed on the base of this device.
Special characteristics
-
sampling rate: upto 50 MHz
-
bandwidth: (-3 dB)- 40 MHz
-
resolution of the ADC is 12 bit; conversion time: 20 ns
-
8 digital inputs for digital signals capture in a synchronous mode
with ADC
-
inbuilt memory for data storage
-
two single-ended channels for analog signals input
-
internal or external triggering
-
external synchronisation input differentiation is switchable
-
external or internal start of analog-digital conversion
-
card inputs voltage overload defence: ±7,5 V
