BLOCK DIAGRAM DESCRIPTION (Continued)

The RF signal from Coax Switch S15 is

split at DIRECTIONAL COUPLER DC1

RF Modulation Assemblies 1A3/1A4. (Refer to figure FO-l. ) The

RF Modulation Assemblies are divided into three functional areas.

RF PATH (CW)

LINEAR MODULATION (CON SCAN)

PULSE MODULATION (A-W/A-F/B/VAR PRI)

(1) RF Path (CW). (Refer to figure FO-1.) The RF source

is a linearized voltage controlled oscillator VCO. (+17 dBm

output)
