2009-140H 14.0 to 14.5 GHz Test Downconverter |
||
| The 2009-140H Test Downconverter converts a 14.0 - 14.5 GHz signal to 950 - 1450 MHz with a low side local oscillator (LO) (non-inverted spectrum). Featuring low phase noise and high stability, this unit is used to downconvert “clean” (having only this frequency) 14.0 - 14.5 GHz signals to 950 - 1450 MHz for test purposes. The 14.0 - 14.5 GHz input is mixed with a synthesized local oscillator (LO) signal to 950 - 1450 MHz. The mixer output is applied to the output amplifier providing a nominal gain of -20 dB. Connectors are 75 ohm female type-F for the 950 - 1450 MHz output and 50 ohm female type-N for the RF input. Front panel LEDs light when DC power is applied (green) and when a PLL alarm occurs (red). DC power is provided by the LNB voltage from the receiver under test or by an external 115 VAC, 60 Hz wall mount power supply (option -P). The 2009 can be mounted on an 1 3/4” X 19 “ rack mount panel (option -R). | ||
