U1084A Datasheet, PDF (8/20 Pages) Keysight Technologies – Acqiris High-Speed PCIe Digitizers with On-Board Signal Processing

Firmware for High-Speed Digitizers
U1084A-DGT with long acquisition memory
U1084A-DGS with simultaneous acquisition and readout
Main Features
• High-speed digitizer firmwares with dual- and single-
channel acquisition modes
• Up to 4 GS/s sampling rate on either channel
The on-board processing engine of the U1084A provides
extended performance for high speed data acquisition.
Smart memory handling with sustained sequential record-
ing mode, allows continuous data acquisition and readout
of high-trigger rate signals.
• Segmented acquisition
• Simultaneous acquisition and readout (SAR) mode for
maintained high measurement throughput (with Option
U1084A-DGS)
Digitizer firmware options
Two digitizer firmwares are available for the U1084A.
• Up to 512 MSamples of acquisition memory with Option
U1084A-DGT, 256 MSamples with Option U1084A-DGS
• 15 ps Trigger Time Interpolator (TTI) for accurate timing
measurements
• High-speed PCI Express x4 bus transfers data up to
520 MB/s to a host processor
Digitizer firmware U1084A-DGT allows the platform to per-
form as a high-speed analog to digital data acquisition mod-
ule with long acquisition memories, up to 512 MSamples.
Digitizer firmware U1084A-DGS in addition to the -DGT
functionality includes a ping-pong memory buffer architec-
ture. The processing memory is split in two so that module
can continuously acquire data into one memory bank
while the other bank is read into the host processor. This
technique is particularly useful for continuous acquisition of
data bursts at a sustained trigger rate.
