<h2>Data Recording and Storage System</h2>
<p>An extremely high-speed (up to 240 MBPS) and high-capacity (several terabytes) <b><a href="../pdf/Data Acquisition Storage and Replay Unit 001-02.pdf">data acquisition, storage, and replay unit</a></b> 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.
<br><br>
These units can be regarded as a large amount of digital memory or analog tape recorders, with extremely high bandwidth.
<br><br>
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.</p>
<h3>Digital Storage and Replay Unit</h3>
<div class="blockquote">
<div class="box"><ul><li>Offers real-time recording and playback</li>
