Chapter 1.
L-Card data acquisition system L-502 based on the PCI Express interface of modern
computer motherboards. L-502 – this system of the proprietary development of the "L-Card" LLC,
it is made on the basis of high-tech production of the company, it provides its own technical support
and maintenance.
The most important characteristics of L-502:
• ADC: 16 bits, conversion frequency up to 2 MHz, with switching to 16 differential channels or 32
channels with common ground. Subranges: ±10 V", "±5 V", "±2 V", "±1 V", ±0.5 V, ±0.2 V.
• DAC (optional):
conversion frequency of up to 1 MHz for each channel.
• Digital input: up to 18 digital inputs of general purpose, asynchronous or synchronous data
collection mode with a frequency of up to 2 million words per second.
• Digital output: up to 16 digital outputs of general purpose, with separate control of the output
resolution of the high and low byte, asynchronous or synchronous data output mode with a
frequency of up to 1 million words per second.
• Processor Blackfin 530 MHz, 32 MB RAM, JTAG input (optional) allows you to use the ready
"advanced" signal processing and control functions inside the L-502 or independently engage in
low-level programming of these functions.
• Galvanic isolation (optional) provides isolation of digital and analog signal inputs/ outputs to all
circuits of the computer.
The above "optional" is reflected in the L-502 module designation system on
The system can consist of one or more modules (boards) L-502, synchronized from each
other, from an internal or external synchronization source.
