measurement by calculating the following equation: LO = ((3xRF)-IF)/2.
EXAMPLE B:
Where: RF = signal generator frequency No. 2 determined in (20) above.
IF = operating frequency of receiver system (1 GHz)
LO = Signal generator No. 1 frequency
LO = ((3xRF) -IF)/2
LO = ((3x9 GHz) -1 GHz)/2
LO = 26 GHz/2
LO = 13 GHz
Signal generator No. 1 frequency would be adjusted to 13 GHz.
adjust RF LEVEL output to 0 dBm.
(24) Connect equipment as shown in figure 3.
NOTE
Ensure equipment is connected as shown in figure 3 and has
completed the 3 hour warm-up before proceeding to (25) below.
NOTE
Use 15% SEARCH MODE on receiver system.
