Module Interface
Coaxial Wires
Jack A7 IF Input
This is the reflected IF signal input connection; b1 for port 1 and
b2 for port 2.
Jack A4 ALC Input
The ALC signal input connection from the HP 85104A test set.
Jack A2 IF Input
This is the incident IF signal input connection; a1 for port 1 and a2

Pin Connections
The pins and jacks used on this connector are described below, any others on
this connector are not used.
Pin Number 1 and 2
These two pins are the analog and dc-supply ground lines.
Pin Number 4
This pin is a +15.0 Vdc supply.
Pin Number 6 and 7
These two pins are both +8.0 Vdc supplies.
Pin Number 9
This pin is a +5.0 Vdc supply.
Pin Number 11
This pin is a -15.0 Vdc supply.
Pin Number 13
This is the Module Sense line. When a highband test set is connected to the
module interface of the HP 85105A, a +5.0 Vdc level is input to this pin. The
result is that the ALC from the test set is routed through the HP 85105A to
the RF source. If the +5.0 Vdc is missing from this pin, the internal ALC of
the HP 85105A is routed to the RF source.
Pin Number 14
This is the +0.5 Vdc/GHz line. See the description in "Rear Panel Features"
of the 0.5 V/GHz line.
Pin Number 16 and 17
These two lines are digital ground.
