Overview |
|
The Mod. N6761 is a 1-unit wide NIM module housing 1 Channel 10 bit 4 GS/s Digitizer on single ended MCX coax. input connector.
The DC offset adjustment (range ± 0.5V) on each channel by 16bit DACs allows a right sampling of a bipolar (Vin=± 0.5V) up to a full positive (Vin= 0 ÷ +1V) or negative (Vin= 0 ÷ -1V) analog input swing without losing dynamic resolution.
The module features a front panel clock In and a PLL for clock synthesis from internal/external references. The data stream is continuously written in a circular memory buffer. When the trigger occurs, the FPGA writes further N samples for the post trigger and freezes the buffer that can be read via USB or optical link. The acquisition can continue without dead time in a new buffer.
The channel has a SRAM memory buffer (7.2 MSamples/ch) divided in buffers of programmable size (1 - 1024). The readout (from USB or Optical link) of a frozen buffer is independent from the write operations in the active circular buffer (ADC data storage).
Zero suppression and data reduction algorithms allow substantial savings in data amount readout and processing, rejecting samples smaller than programmable thresholds.
Mod. N6761 supports multi-board synchronization allowing all ADCs to be synchronized to a common clock source and ensuring Trigger time stamps alignment. When synchronized, all data will be aligned and coherent across multiple N6761 boards.
The trigger signal can be provided via the front panel input as well as via the software, but it can also be generated internally with threshold auto-trigger capability
N6761 houses USB 2.0 and optical link interfaces. USB 2.0 allows data transfers up to 30 MB/s. The Optical Link supports transfer rate of 80 MB/s, and offer daisy-chain capability. Therefore it is possible to connect up to 8/32 ADC modules to a single Optical Link Controller (Mod. A2818/A3818).
