MODEL 3116-T31-148
Multi-Band, Block Translator
1.0 General
1.1 Equipment Description
The 3116-T31-148 Translator converts one of three input RF bands to one of three output RF bands in three
different translations. Dual Conversion frequency translation is used for all inputs to minimize spurious. Front
panel LEDs provide indication of DC Power, and PLL Alarm. The RF to RF gain is +20 dB, maximum.
Connectors are SMA female for the RF out, RF in and RF in Monitor and BNC female for the external
reference input and reference output. In AUTO, the 10 MHz reference stays in external if the external level is in
the +2 to +8 dBm range. Gain, band select, LO frequency, and internal 10 MHz frequency are controlled by the
Ethernet M&C or via the Monitor/Control connector. The 3116-T31-148 is powered by a 100-240 ±10% VAC
power supply; and housed in a 1.75” X 19” X 17” rack mount chassis.
