The RFA300A 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: Complex Modulation Error Ratio Signal to Noise Ratio Error Vector Magnitude Pilot Amplitude Error Out-of-Channel Emissions Frequency Response Error Group Delay Amplitude Error Phase Error Phase Noise Error Peak to Average Ratio 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.
