S.Module2 HS12-20 (product preview)

The S.Module2 HS12-20 is a small size data acquisition board, providing up to two complete analog input channels with a large FIFO-memory and two analog output channels.

Analog Inputs
Analog inputs are single ended and DC-cupled. The input voltage range can be set by software from 0.5 to 2.0 Vpp in steps of 0.1 V.
Analog signals digitized to 12 bits at sample rates up to 20 MHz per channel. Both input channels can work complete synchron. The clock signal for A/D conversion can be provided by either an internal sample rate generator or by an external clock signal.
On the module are several trigger modes available. Beside an analog trigger with Software-adjustable threshold there are various digital trigger opportunities integrated.
At the end of conversion data stored in the FIFO memory. Using the FIFO allows interrupt generation after a single conversion or at serveral FIFO limits.

Analog Outputs
The module also includes two analog output channels with maximum update rates of 83 kHz. Output voltage range is fixed to 2.5V.

Interface
The interface contains a 16/32 bit data and a 6 bit address bus, an I/O enable, a read, a write, a clock and two interrupt lines. This enables simple connection of signal processing boards in the S.Module2- and D.Module2-Series without additional hardware, as well as simple integration with other processors/controllers. Data can be transfered as single word or in burst mode. The transfer rate can be up to 400 Mbyte per second.
