e representatives qualified and authorized to represent its interest and participate in the on-site tests and data collection. This test process may be performed by a third party and is viewed as a collaborative effort. Only equipment surviv- ing the on-site test process will be accepted and paid for. Equipment defined as a transmitter will be detailed in each RFQ for each site and station. On-site tests will be conducted. FCC Proof of Performance Measurements required by the FCC for an application for license. Measurements shall be made at the output of the DTV Mask or, if present, the output of the RF combiner. All tests PRACTICAL IP AND TELECOM FOR BROADCAST ENGINEERING AND OPERATIONS and measurements of transmitter performance shall be conducted with transmitters operating at the power output levels required to meet the effective radiated power specified by the FCC construction permit or license. Power measurements shall be made with the trans- mitter(s) operating into the dummy load, with results documented as follows: ATSC Upper sideband response ATSC Lower sideband response Envelope delay versus frequency demonstration compliance with Section 73.687(a)(3) and (4) of the FCC Rules and Regula- tions (47 CFR) DTV transmitter frequencies using a frequency counter of ad- equate accuracy. Measurements shall be made at least three times with a minimum of eight hours between measurements. The frequency reading shall be compared with the reading obtained on the frequency and modulation monitor. Spurious components from 0 Hz to 1.8 GHz (if any) apparent in the radiated output of the DTV transmitter. A spectrum analyzer shall be used to make these measurements. Any out-of-band radiation shall not exceed FCC maximum allowable values. Photographs or other printed facsimile of the waveform shall be taken and shall be included in the proof of performance report.
