The U.S. Geological Survey, EROS Data Center, Sioux Falls, South Dakota, has a requirement for an L-3 Communications Microdyne 1620-PC Diversity Combiner, to be used in conjunction with two Microdyne 700-MR Telemetry Receivers. It shall be capable of accepting the 20 Mhz IF signals from the two 700-MRs for diversity combining. It shall also accept both receivers AGC and Logic signals and shall output two 20 Mhz PM demodulated video signals. It shall accept a 5 Mhz reference signal. It shall be equipped with the 758-D Multi Mode Demodulator option including the 20Mhz VCO. It shall have both a RS-232 and IEEE-488 communications port. It shall have a pre-detection combining mode with a bandwidth of 15 MHz, and impedance of 50 ohms, and input level of -10 dBm +or- 15 dB and an input frequency of 20 MHz. The AGC inputs shall have a voltage range of 0 to -10 volts and a common mode rejection and control signal rejection of less than .5 dB variation. The logic inputs shall be TTL compatible. It shall be capable of PM demodulation and shall have loop bandwidth options including: 3, 10, 30,100, 300,1000, and 3000 Hz. The PM demodulator shall have an operating threshold of -14 dB carrier to noise ratio (2nd IF bandwidth) and +6 dB signal to noise ratio in the phase lock loop. It shall have BNC type connectors. It shall be capable of operating on 120/240 VAC 50-400Hz and shall come with a power cord and rack slides so it can be mounted in a 19-inch rack. This requirement is considered a "Brand Name or Equal" product manufactured by L3 Communications Microdyne, 491 Oak Road, Ocala, Florida. Required delivery date is March 1, 2002.
