Figure C-3. Interface Signals of the Source Module Connector

The codes indicated on the illustration above translate as follows:

MOD DOSource module data line zero. Signals MOD DO through MOD D3 are the mm source module data bus lines (bi-directional).

MOD Dl	Data	line	one.
MOD D2	Data	line	two.
MOD D3	Data	line	three.
MOD CO	Source module control line zero. Signals MOD
	CO and MOD Cl are the control lines for the
	read/write to and from the mm source module.
MOD Cl	Control line one.
CLAMP CNTL	Source module clamp control (not used).
MOD SENSE	Source module sense. A 1mA current is injected
	on this line by the mm source module to
	indicate its presence. This signal always equals
	o v .

L MOD RF OFF Low = RF off. Source module RF is turned off.

EXT LVL RET Source module external leveling return.

EXT LVLSource module external leveling input, from the mm source module.

0.5V/GHzInternal 0.5V/GHz to the mm source module.

-15vPower supply. Range is -14.25 to -15.9OV.

+15vPower supply. Range is +14.25 to +16.4OV

+8VPower supply. Range is i-7.75 to +8.25V.

+5vPower supply. Range is t4.75 to t5.45V.

DIG GNDDigital ground.

MOD ANLG GND Source module analog ground.

ANLG GND RET Analog ground return.
