U1084A - High-Speed PCIe Digitizers with On-Board Signal Processing - 4

High-Speed Digitizer with On-Board Signal Processing Front end mezzanine with ADC The analog mezzanine contains the analog signal conditioning (amplification, offset, and channel interleaving) as well as the analog-to-digital converter (ADC) component. Impedance on the two input channels (CH1, CH2) is fixed at 50 Ω ± 1%. Either input can be used as a trigger source. Normally the two channel inputs are sent to their dedicated ADCs and simultaneously sampled at 2 GS/s. Alternatively, with channel interleaving, the signal from either one of the channels can be sent to both ADCs to achieve...

U1084A - High-Speed PCIe Digitizers with On-Board Signal Processing - 5

Flexible data processing The FPGA provides capacity for real-time processing of the acquired data. The firmware options loaded into the processing FPGA can provide either: The U1084A is able to hold any two of the available firmware options (-DGT/-DGS, -AVG or -TDC), and can switch between these two in a matter of seconds without powering-off the host computer. This feature adds flexibility and enables the digitizer to be used in a wider field of applications, performing additional measurements on the go. • -DGT/-DGS: Basic high-speed digitization with long acquisition memory or...

U1084A - High-Speed PCIe Digitizers with On-Board Signal Processing - 9

Sequence acquisition Digitizers acquire waveforms in association with triggers. Each waveform is made of a series of measured voltage values (sample points) that are acquired by the ADC at a uniform clock rate. To maximize sampling rates and utilize memory as efficiently as possible, the U1084A digitizer firmwares include both single and sequential storage modes. Minimum bank switching dead time for remarkable sustained rates The sustained sequential recording (SSR) mode of the U1084A-DGS digitizer maximizes the available data throughput allowing data acquisition to run in parallel to the...
