General Information 1
Keysight 11667C/D Power Splitter Operating and Service Manual 13
Overview
Keysight 11667C/D power splitter is a two-resistor power splitter used in network analysis where
one output arm is used for leveling or to supply a reference signal for ratio measurements.
In a network analyzer system, the node at the fork of the power splitter is held constant by the
leveling action of the network analyzer reference channel (see Figure 1-1). Because a virtual
ground is present at the node, the resistance in each output arm is 50 ohms, giving a 50 ohm
matched output impedance.
The ratio between the two power splitter arms is not affected by source power level variation.
Variations in power level appear in both arms equally and
simultaneously.

2Installation
16 Keysight 11667C/D Power Splitter Operating and Service Manual
Initial Inspection
1Inspect the shipping container for damage. If the shipping container or cushioning material is
damaged, it should be kept until the contents of the shipment have been checked for
completeness and the instrument has been checked both mechanically and electrically.
– Check for mechanical damage such as scratches or dents.
– Procedures for checking electrical performance are given under “Operator’s Check” on
page 20 or Chapter 4, "Performance Tests".
2If the contents are incomplete, if there is mechanical damage or defect, or if the instrument
does not pass the electrical performance test, contact the nearest Keysight Technologies Sales
and Service office (refer to “Sales and Technical Support” on page 3). Keysight will arrange for
repair or replacement of the damaged or defective equipment. Keep the shipping materials for
the carrier’s inspection.
3If you are returning the instrument under warranty or for service, repackaging the instrument
requires original shipping containers and materials or their equivalents. Keysight Technologies
can provide packaging materials identical to the original materials. Refer to “Sales and
Technical Support” on page 3 for the Keysight office nearest to you. Attach a tag indicating the
type of service required, return address, model number and serial number. Mark the container
FRAGILE to insure careful handling. In any correspondence, refer to the instrument by model
number and serial number.

Preparation for Use
Mating Connectors
The accuracy and repeatability of each measurement depends on the proper care and use of the
2.4/1.85 mm connectors. Visually inspect and clean connectors before every connection. Measure
mechanical tolerances (pin depth) with a precision gage prior to the connector's first use, and
periodically thereafter. Torque connections to 8 in-lb (90 N-cm). Information concerning the
proper maintenance, inspection, and gaging of connectors is provided in the Keysight Microwave
Connector Care manual (PN: 08510-90064).
Environmental Conditions
Operate the power splitter only in environments within the limits listed in Table 2-1 and Table 2-2.
Storage and shipment environments must meet the conditions below.
CAUTION
Maximum input power to the Keysight 11667C/D is +27 dBm. Exceeding this limit will damage
the resistor network and void the warranty.

Operator’s Check
The operator’s check is a quick evaluation of the power splitter 's operation. Perform this procedure
to verify that the power splitter is functioning.
1Visually inspect the input port and both output ports for defect or damage. Mating defective or
unclean connectors degrade the measurement and damage the mating connector.
2Perform the Output Tracking test (over the frequency range you will be using). Refer to
Chapter 4, "Performance Tests" for this procedure.
If the power splitter fails either check, contact Keysight for repair or replacement.
