1 INTRODUCTION
The purpose of this manual is to explain how the digitizer is operated. The datasheet [1] contain param-
eters for the specific versions of digitizer. References to software commands are made. In some places,
pseudo code is used for description. See
[2] for details on how to use the software commands and see
[3] for general guidelines on programming the digitizer.
1.1 ADQ7DC Architecture
The ADQ7DC architecture is shown in Figure 1 . References to the corresponding sections with further
information are also included.
1.2 Fundamental design properties
There are some fundamental design properties that are necessary to understand before continuing.
# DESCRIPTION REFERENCE
a Switch between 1 channel and 2 channels 2
b Signal conditioning analog front-end. 2
c High speed and high resolution A/D converter. The A/D converter operate interleaved at
5 GSPS per channel. The A/D converters can be further interleaved to get 10 GSPS. 3
d Digital calibration of gain and offset. 2
e Teledyne SP Devices’ proprietary technologies for signal quality enhancement; ADX for
SFDR in radio systems and DBS for baseline stability in pulse data systems. 3
f Acquisition engine that handles triggers and controls the data flow. 4 , 7
g Data FIFO to buffer data before transmission to the host PC. 7
h The data transfer to the host PC is through a PCIe or a USB3.0 link. 7
i Flexible clock generator 5
j General Purpose digital Input and Output control. 6
