The 2009-59 Downconverter converts a 5.925 - 6.425 GHz signal to 950 - 1450 MHz with a high side local oscillator (LO) (inverted spectrum) for loop-back applications. With low phase noise, this unit down converts “clean” (having only this frequency) 5.925 - 6.425 GHz signals to 950 - 1450 MHz for test purposes. The 5.925 - 6.425 GHz input is mixed with a synthesized local oscillator (LO) signal to 950 - 1450 MHz. The mixer output goes to the output attenuator providing a nominal gain of -35 dB. Connectors are 75 ohm F female for the 950 - 1450 MHz output and 50 ohm N, female for the RF input. Front panel LEDs show DC power is applied (green) and if a PLL alarm occurs (red). DC power is provided by the LNB voltage from the receiver under test or by an external wall mount power supply (options -P and -P4). Option -C has no power supply and is powered by an external power supply like the 2000-01. The 2009 can be mounted on an 1 3/4” X 19” rack mount panel (option -R). Models with option -H operate over an extended -20˚C +60˚C temperature range.
