H2714 & 2715 Spectrum Analyzer Reference
H2715 Spectrum Analyzer Service
HCable TV RF Measurements Software User
For manual ordering information, refer to Appendix F: Accessories & Options or
contact your local Tektronix Field Office or representative.
Who Should Use This Manual?
This manual is intended for electronic technicians with experience in making
cable television-related measurements.
Standards and Conventions Used
Most terminology is consistent with standards adapted by IEEE and IEC.
Abbreviations used in the instrument and in the documentation are consistent
with ANSI Y1.1–1972. Copies of the ANSI and IEEE standards can be ordered
from the Institute of Electrical and Electronic Engineers Inc.
Change/History Information
Changes to the 2715 may occur or manual errors may be found that make some
of the information in the manual inaccurate. When this happens, Manual Change
Information notices containing the corrected information are inserted at the rear
of the manual. This ensures that the manual contains the latest and most accurate
information available when the product is sold.

Manual Organization
Sections 1 through 3 contain material that enables the beginning or experienced
operator to safely power up and initially normalize the spectrum analyzer.
Sections 4 through 6 provide detailed explanations and some measurement
examples that may be especially useful. The examples should be read while
interactively using the spectrum analyzer and carrying out the instructions. In
this way, you quickly acquire the knowledge and skills necessary to make
accurate measurements. The end of one example and start of the next are
indicated by a settings box that looks like this:
8.75MHZ (AUTO SWEEP) M 11.45 MHZ
23.5DBMV M 13.8 DBMV
600KHZ 10 DB/
300KHZ RBW STD CH 2
The box shows what the control settings of the spectrum analyzer should be to
continue with the example that follows it. The contents of the box resemble the
spectrum analyzer’s on-screen data readouts. Each example begins with the
sweep control in AUTO mode. To remind you of this, (AUTO SWEEP) is shown
in the top center of the box. The parentheses mean the enclosed item is not part
of the normal on-screen readouts.
Six appendices, a glossary, and an index contain information about a number of
topics useful, but not essential, to spectrum analyzer operation.
Introduction contains a brief description of spectrum analysis and reviews the
characteristics of the Tektronix 2715 Cable TV Spectrum Analyzer.
Getting Started enables you to safely apply power and signals to the spectrum
analyzer. You become acquainted with the fundamental controls of the instru-
ment and make your first measurements using a firmware-based CATV
measurement routine and the built-in calibration signal.
Operating Basics provides most of the information needed for routine operation.
Dedicated Controls explains the features of the spectrum analyzer and the
benefits you gain from each control and menu option as you go through
examples. You learn to easily obtain accurate spectral and time-domain
measurements.
CATV Measurements describes CATV requirements and offers step-by-step
procedures to conduct automated measurement routines.
