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:
H
Complex Modulation Error Ratio
H
Signal to Noise Ratio
H
Error Vector Magnitude
H
Pilot Amplitude Error
H
Out-of-Channel Emissions
H
Frequency Response Error
H
Group Delay
H
Amplitude Error
H
Phase Error
H
Phase Noise Error
H
Peak to Average Ratio
H
Channel 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.
