An extremely high-speed (up to 24 Mbps) and high-capacity
(several terabytes) data acquisition, storage, and replay
unit ensures continuous recording or replay of stored signals.
The units have a variety of front ends and ADCs. These allow
analog signals of high bandwidth (limited by ADC) to be
digitized, stored, replayed via DACs, and upconverted. The
digitized signals can be transferred to and from PC via
Ethernet or internet. The upconversion allows high-fidelity
storage and replay of a large amount of analog or digital
signals.
These units can be regarded as a large
amount of digital memory or analog tape recorders, with
extremely high bandwidth.
These are widely used in recording, storage,
replay, and simulation of a variety of GPS (both L1 and L2
signals) and/or other signals with high bandwidth and under
different conditions.
