2004 Agile Satellite Test 1-2 GHz Upconverter

  
The 2004 takes a 70 MHz IF signal and converts it to 950 to 2050 MHz in 1MHz steps with a high side 1020 to 2120 MHz LO. Over a limited frequency range, the 2004 also operates with a 140 MHz input (950 - 1980 MHz out with high side LO; 1160 - 2050 MHz out with low side LO) and 70 MHz in with low side LO (1090 - 2050 MHz out). The IF input is mixed with a synthesized 1020 - 2120 MHz local oscillator signal. The output frequency is selected using up and down tune push button switches which control the synthesized oscillator. The 2004 has a front panel alarm LED that lights when the PLL is unlocked and this alarm signal goes to an open drain FET output. A yellow LED on the front panel indicates remote operation. The output of the mixer is applied to the output switched attenuator providing output levels of -35dBm, -55dBm, or -75dBm. Power is provided by a wall-mount power supply and connectors are BNC female.
