CHAPTER 1
GENERAL INFORMATION
INTRODUCTION
The Hukk Engineering Model CR1200R Digital Signal Analyzer
allows monitoring and testing of Quadrature Amplitude Modula-
tion (QAM) signal transmissions as well as typical Cable TV
NTSC television signals.
QAM signaling is used on broadband systems to deliver com-
pressed digital video signals and is also used with DOCSIS com-
patible cable modems. The CR1200R demodulates the carrier and
performs error detection on the live program data stream.
In addition, the CR1200R performs analog tests on NTSC, HRC
and IRC signals, providing video and audio measurements of these
signals.
The return path option allows a fully functioned spectrum ana-
lyzer display of both the forward and return path. The zero span
analyzer function allows accurate measurements of return path
TDMA/QPSK signals.
MANUAL OVERVIEW
This operating manual describes the physical and functional fea-
tures, operation, and specifications of the Sunrise Telecom, Hukk
Division Model CR1200R Digital Signal Analyzer.

INSTRUMENT OVERVIEW
Figure 1 on page 6 shows the front panel of the Sunrise Telecom
Hukk Division Model CR1200R Digital Signal Analyzer. A large
liquid crystal display (LCD) indicates instrument status, signal
identification, and measurement values. The controls are pres-
sure-sensitive keypad switches with tactile feedback. A 75-ohm
“F” connector accepts the RF input signal. A female DB9 connec-
tor interfaces to a computer port. A DC input accepts power from
the supplied AC adapter or a 12 volt DC source. The CR1200R is
packaged in a rugged weatherized, hard plastic case.
