The Sabre Express is available in four channel models supporting a maximum A/D sampling rate up to 250 MS/s. ADC data can be captured in four, dual or single channel modes with input voltage range at ±1V and ±240mV low-range option.
All input channels are fixed for DC-coupling, 50Ω .
The analog input bandwidth is 150 MHz with 50 Ω input impedance.
The SabreExpress includes 4 GS (8 GB) of onboard acquisition sample memory. The onboard acquisition memory size is shared and equally divided among all active input channels (4, 2 or 1) when acquiring data to onboard memory.
With the optional eXpert PCIe Data Streaming FPGA Firmware package, the dual-port architecture of the onboard memory is utilized as a large FIFO buffer for streaming acquired data to host PC memory via the digitizer’s PCIe Gen3 x8 interface at sustained rates up to 2 GB/s supporting the maximum sampling rate for all channels active.
