RFA300A Measurement Set 8VSB 1-1
Getting Started
This chapter provides basic information about using and installing the RFA300A
Measurement Set 8VSB. There is information about the physical instrument and
introductory material on how to operate it. Once you have a basic understanding,
proceed to the next chapter, Operating Basics, to form a conceptual model of
how the measurement set works.
Product Description
The measurement set provides information on 8VSB digital television signals in
conformance with the ATSC Digital Television Standard. Signals are acquired at
the transmitter and the measurements consist of the following:
HComplex Modulation Error Ratio
HSignal to Noise Ratio
HError Vector Magnitude
HPilot Amplitude Error
HOut-of-Channel Emissions
HFrequency Response Error
HGroup Delay
HAmplitude Error
HPhase Error
HPhase Noise Error
HPeak to Average Ratio
HChannel Spectrum (display of the selected channel, not a measurement)
The instrument’s measurements can run continuously, thereby monitoring
transmitter performance on a constant basis. Operation of the instrument is
controlled from the front panel keypad and the touch screen or from an attached
keyboard and mouse. Figure 1--1 shows the front panel of the measurement set.

Installation
Read this section before attempting any installation procedures. This section
describes site considerations, power requirements, and ground connections for
your instrument.
Check the Shipping List
Verify that you have received all of the parts of your measurement set. Use the
shipping lists that came with your instrument to compare against the actual
contents of your order. You should also do the following:
HVerify that you have the correct power cord for your geographical area.
HVerify that you have the CD that contains a backup copy of the installed
software. Store the CD in a safe location where you can easily retrieve the
software for maintenance purposes.
HVerify that you have a boot disk in case you reformat the hard drive or
damage operating system files or drivers.
NOTE. Keep the software packaging available. You will need it to enter the
Windows NT software registration number when you first power on the analyzer.
(See step 3 under Powering On and Off on page 1--18.)
HVerify that you have all the other standard and optional accessories that you
ordered.

for which the instrument is rated.
Hardware Installation
This section deals with hardware installation. To reinstall software, refer to
Appendix C: System Recovery.
The factory installed cabinet is designed to operate in an equipment rack (see
Rackmount Installation on page 1--7). The optional portable cabinet allows you
to operate the instrument on a bench or cart (see Portable Installation on
page 1--12). For proper cooling, at least two inches (5.1 cm) of clearance is
recommended on the rear and sides of the instrument cabinet.
The measurement set is limited to installations where a single, high-amplitude,
8VSB RF signal is available for direct input to the measurement set. Refer to RF
Connections on page 1--14.
