Description

Description

The Agilent 11612V Option K21 is a 50 GHz bias network with force/sense capability. The
Option K21 provides a force connection to allow input of a current or voltage signal, and a
sense connection to allow monitoring of voltage or current. A ground connection for
application of an active ground is also provided. The force, sense, and ground are triaxial
connectors.

When used as part of the 85122A system, the bias network is intended to be connected to
cables from the SMUs in the 4142 DC source/monitor. The force and sense connectors on
the quadraxial cables from the SMUs are connected to the force and sense connectors on
the bias network. The triaxial cable from the GNDU is connected to the ground connector
on the bias network.

The RF connectors on the bias network are 2.4 mm (f) connectors. The Agilent 11612V
Option K21 is used at port 2 of the network analyzer and Option K11 is used at port 1. The
RF cable from the network analyzer test port is connected to the RF IN port of the bias
network. The RF OUT port of the bias network is connected to the probes, or the fixture, or
the device itself.

Bias Network

Bias Network

Internally, each bias network includes two bias tees, one for force and one for sense. The
force bias tee includes a capacitor that functions as a DC block and high-pass filter. The
sense bias tee provides a through path for DC voltage. Oscillation suppression networks
are located on each DC path to help prevent bias oscillation of the DUT. Figure 1 is a
schematic diagram of the bias network.

Instrument Markings

When you see this symbol on your instrument, you should

!

refer to the instrument’s instruction manual for important
information.

This symbol indicates hazardous voltages.

The laser radiation symbol is marked on products that have
a laser output.

This symbol indicates that the instrument requires
alternating current (ac) input.

The CE mark is a registered trademark of the European
Community. If it is accompanied by a year, it indicates the
year the design was proven.

The CSA mark is a registered trademark of the Canadian
Standards Association.

Safety
Earth
Ground

This text indicates that the instrument is an Industrial

ISM1-A

Scientific and Medical Group 1 Class A product (CISPR 11,
Clause 4).

This symbol indicates that the power line switch is ON.

This symbol indicates that the power line switch is OFF or
in STANDBY position.

This symbol indicates the product meets the Australian
Standards.

This is a Safety Class I product (provided with a protective earthing
terminal). An uninterruptible safety earth ground must be provided
