The transmitter shall meet the requirements of this document and shall operate without degradation of the performance defined in this document during and after exposure to any reasonable combination of the environmental conditions specified in this document. Reasonable combination of environments means any combination of environments which can be simultaneously duplicated with standard laboratory equipment or any combination of environments which can be expected to be encountered in world wide shipping, storage, checkout, and operation. 2.3.1 Channel Frequency. The exact unmodulated carrier frequencies at which the transmitter shall transmit shall be as specified: Channel 1: 1720.000 MHz Channel 2: 1735.000 MHz Channel 3: 1750.000 MHz 2.3.2 Carrier Frequency Quality. After the warm-up period specified in 2.3.9, the radio frequency (RF) carrier shall meet the following requirements: 2.3.2.1 Combined Stability and Accuracy. The unmodulated carrier frequency at the RF output of the transmitter shall be within 0.03 percent of the specified unmodulated carrier frequency as designated by the contract. 2.3.2.2 Carrier Shift Due to Modulation. When modulated with a symmetrical signal of an amplitude that does not cause a peak-to-peak phase deviation of more than 7 radians and which is of any frequency between 30 Hz and 5 MHz, the average frequency at the RF output of the transmitter shall not shift from the unmodulated carrier frequency by more than 0.01 percent of the unmodulated carrier frequency. 2.3.2.3 Incidental FM. The peak-to-peak deviation due to incidental FM shall not exceed 10 kHz. Incidental FM is defined as any deviation of the carrier occurring at any frequency over the modulation bandwidth up to 10MHz, with no external modulation applied. 2.3.2.4 Incidental PM. The peak to peak incidental PM deviation shall not exceed 0.08 radians. Incidental PM is defined as any deviation of the carrier occurring at any frequency over the modulation bandwidth up to 10MHz, with no external modulation applied. 2.3.3 Video Input. The transmitter shall accept RS-170, 525 line, 2:1 interlaced video as its input signal. The video input of the transmitter shall have the following characteristics when the transmitter is operating in any mode except the OFF mode. 2.3.3.1 Input Impedance.

The modulating signal present on the RF output shall be the video at the video input. 2.3.4.2 Modulation Bandwidth. The baseband signal from the video system is a nominal 1.0 volt peak (2 volts peak to peak) signal occupying a 3dB bandwidth between 30Hz and 10MHz. This signal is comprised of standard RS-170 525-line video with digital data on each horizontal line. 2.3.4.2 Modulation Polarity. For frequencies within the modulation pass band, a positive going voltage at the video input shall cause an advance in the RF output phase relative to the unmodulated carrier frequency. 2.3.4.3 Modulation Sensitivity Pre-set. The modulation sensitivity shall be adjusted prior to delivery of the transmitter to the procuring activity such that a 1.00 0.25 volt AC peak-to-peak 1kHz signal applied at the video input causes the RF output phase to deviate 2.00 0.2 radians peak-to-peak. The sensitivity shall not change by more than 15 percent during testing under the different conditions using a 1kHz, 3.0 0.05 volt peak-to-peak signal as the video input. 2.3.4.4 Spurious Amplitude Modulation. The RF output shall not exhibit amplitude modulation of more than 7.5 percent relative to an unmodulated carrier. 2.3.4.5 Modulation Linearity. When the peak-to-peak deviation of the RF output is 8MHz or less, the modulation sensitivity shall not vary as a function of the modulation signal amplitude from the least squares modulation sensitivity by more than 500kHz per volt. The least squares modulation sensitivity shall be determined by the least squares method using data points taken with output peak-to-peak deviations of 100 kHz, 300kHz, 500kHz, 1 MHz, 3MHz, and 8MHz at deviation rates of 1kHz and 10kHz. 2.3.4.6 Deviation Limits. When the phase deviation commanded by the modulating signal is 6 radians peak-to-peak, the deviation of the RF output shall be limited such that the ratio of the modulation sensitivity to the least squares modulation sensitivity is at least -3dB. When the commanded deviation is greater than 6 radians peak-to-peak, such ratio shall roll off at a rate of at least 6dB per octave. 2.3.4.7 Modulation Distortion. When the commanded deviation of the RF output is less than 8MHz peak-to-peak, the total harmonic distortion added to the modulating signal by the transmitter shall not exceed 5 percent of the fundamental of a sinusoidal pre-emphasized modulating signal. 2.3.5 RF Power Output. When the transmitter is operating in the off mode or the warm-up mode, the RF output at any frequency shall be less than -80dBm. After the warm-up period specified in 2.3.9, the transmitter shall deliver a minimum RF output of 25 4 watts into a 50 5 ohm load. 2.3.6 Antenna System Compatibility. The transmitter shall meet the requirements of this document when the RF output is operating into an antenna system having a VSWR of up to 1.8:1. The transmitter shall operate as specified herein with the load impedance of the antenna system being of any impedance and phase angle to produce the specified VSWR. The transmitter performance shall not be degraded other than for reduced power output, when the RF output is operating for a five minute period, either continuously or intermittently, into mismatched loads which produce a VSWR of greater tan 1.8:1 including open circuits and short circuits. After removal of the mismatched loads, and a return to a load which has a VSWR of 1.8:1 or better, the transmitter shall resume normal operation within the requirements of this document within 0.5 seconds. 2.3.7 Chassis Ground. Chassis ground shall be the transmitter mounting plate. 2.3.8 Input Power. The transmitter shall meet the requirements of this document when operating from a 28 2Vdc source.
