Model 2089-17 Agile Downconverter
The 2089-17 Agile Downconverter converts a 1700 to 1950 MHz signal to 56 ± 6 MHz in 1MHz steps.
EQUIPMENT DESCRIPTION
The 2089-17 Agile Downconverter converts a 1700 to 1950 MHz signal to 515 MHz in 1MHz steps with a low side 1185
to 1435 MHz first LO and then to 56 ± 6 MHz with low side 459 MHz LO. Up and down tune push buttons control the output
frequency displayed on the LED indicators . Frequency selection can be remotely selected via a RS232C data input. A red LED
PLL alarm lights when the PLL is unlocked and goes to an open drain FET output. A Yellow LED indicates remote operation.
