50.If the spectrum analyzer center frequency is 300 MHz, the voltage at A14J18 pin 3 should measure -3.35 V f0.25 V. The voltage may also be determined from the following equation:

V = -(first LO Frequency -2.95 GHz) x 2.654 V/GHz

51.The voltage at A14U330 pin 2 should measure -3.4 V f0.2 Vdc. This represents a current setting the YTO to approximately 2.95 GHz.

52.Return jumper A14J23 to the NORMAL position.
