Description
The Keysight U3024AH10 is a Multiport Test Set Extension designed to be configured for high
power measurements in either a 14 or 24-Port network analyzer measurement system. Two
U3024AH10 Test Sets are required for the 24-Port network analyzer system, as shown in
Figure 2, page 2. The Keysight U3024AH10 has the following key features:
•10 Test Ports (2.4 mm male connectors)
•Low-loss mechanical RF switching
•High-powered device measurement capability
•N-Port calibration and full cross bar measurement capability
•Frequency range of operation: 10 MHz - 40 GHz (Standard Opt 700)
•Keysight PNA-X compatibility with rear panel Test Set I/O interface for operational control.
The PNA Option 551 is required. An external personal computer is not required.
The Keysight N5224A/B, N5225A/B, N5244A/B, and N5245A/B PNA/PNA-X
Network Analyzers will be referred to throughout this document as the PNA-X.
The U3024AH10 will be referred to as the Test Set.
Measurement Application Notes
Low Loss DUT Measurements
Low loss trace ripple is a product of switch repeatability and calibration technique. Low
insertion loss measurements exhibiting a 0.1 dB uncertainty ripple residing on the
measurement response is not uncommon.
Switch Configuration Command Speed
When writing address and data values to the test set directly, include a 15ms wait before
issuing another address and data set. The delay of 15ms is required for the test set internal
switches to settle. Failure to add the delay could cause the test set internal switches to stick
or cause intermittent failures.

Verifying the Shipment
To verify the contents shipped with your product, refer to the “Box Content List” included with
the shipment.
Inspect the shipping container. If the container or packing material is damaged, it should be
kept until the contents of the shipment have been checked mechanically and electrically. If there is
physical damage, refer to “Contacting Keysight” on page 99. Keep the damaged shipping
materials (if any) for inspection by the carrier and an Keysight Technologies representative.
Network Analyzer Requirements
All network analyzers require Option 551 to be installed for multiport operation (N-Port error
correction and measurement capability). Table 2 provides a listing of other network analyzer
option requirements. In order for the measurement system to cover the full frequency range of the
Test Set option listed, the network analyzer's frequency range should equal or exceed that of the
Test Set.

Specifications
The U3024AH10 performance is based on external components such as the calibration kit and
network analyzer. There are no internal adjustments in the Test Set, therefore an annual
calibration is not required. A functional certificate is supplied for the U3024AH10 only.
Specifications for the U3024AH10 Multiport Test Set are characteristic for the system
performance of the PNA-X and Test Set. Actual performance of the system is based on the
customer's PNA-X that is used with the Test Set and components used for high power
configurations.
The life expectancy of the following switches are 5 million cycles. When
making measurements using more than one port, single sweeps are
recommended to minimize switch cycles.
•87106-60069 (x4)
Power Requirements
Verify that the required ac power is available before installing the Test Set to the PNA-X.
•100/120/220/240 VAC (50/60Hz)
•The instruments can operate with mains supply voltage fluctuations up to ± 10% of the
nominal voltage.
•Air conditioning equipment (or other motor–operated equipment) should not be placed on
the same AC line that powers the Test Set and PNA-X.
•Table 4 below contains the maximum wattage for all instruments. This table can be use to
determine the electrical and cooling requirements.
This is a Safety Class I product (provided with a protective earthing ground
incorporated in the power cord). The mains plug shall be inserted only into a
socket outlet provided with a protective earth contact. Any interruption of the
protective conductor, inside or outside the instrument, is likely to make the
instrument dangerous. Intentional interruption is prohibited.

Environmental Requirements
Refer to the PNA-X series standard documentation for environmental requirements.
Environmental Tests
The Test Set complies with all applicable safety and regulatory requirements for the
intended location of use.
•Pressure Altitude (Operation)
3,000 meters (~10,000 feet)
•The instrument can safely operate in a relative humidity of 80% for temperatures to 31
degrees C, decreasing linearly to 50% relative humidity at 40 degrees C.
Equipment Heating and Cooling
If necessary, install air conditioning and heating to maintain the ambient temperature within the
appropriate range. Air conditioning capacity must be consistent with the BTU ratings given in
Table 4.
Ventilation Requirements: When installing the instrument in a cabinet, the
convection into and out of the instrument must not be restricted. The ambient
temperature (outside the cabinet) must be less than the maximum operating
temperature of the instrument by 4 °C for every 100 watts dissipated in the
cabinet. If the total power dissipated in the cabinet is greater than 800 watts,
forced convection must be used.
Required Conditions for Accuracy Enhanced Measurement
Accuracy–enhanced (error–corrected) measurements require the ambient temperature of the
PNA-X and Test Set to be maintained within ± 1 °C of the ambient temperature at calibration.
Dimensions and Space Requirements
Standard installation of the Test Set and PNA-X includes configuration and installation on a
customer provided lab bench or table top of adequate size and strength. For weight, dimensions
and space requirements, refer to the network analyzer documentation that is used to configure
the Test Set.

Standby Switch
This switch is used to place the internal DC power supply into Standby mode only. It is not an
AC line switch. The main power cord can be used to disconnect AC line power from the Test
Set.
Active LED
When the Test Set is connected and addressed by a PNA-X, the LED is ON (illuminated).
When the LED is OFF (not illuminated), the Test Set is in Standby, or not being addressed by
the PNA-X. Note: When two Test Sets are used, as in the 24-Port System, the first Test Set
connected to the PNA-X will never have an ON Active LED. Instead, the last Test Set will be
the Test Set showing the Active LED status for all.
•If all of the odd numbered port LEDs are Off, PNA-X Port 1 is active and the Odd Test
Ports are terminated.
•If all of the even numbered port LEDs are Off, PNA-X Port 2 is active and the Even Test
Ports are terminated.
Test Ports - 2.4 mm Bulkhead (male)
These ten ports are labeled Ports 3 to 12, and are the measurement ports for your DUT. The
bulkhead connector has a ruggedized hex nut that is 20 mm across the flats and is
compatible with Keysight torque wrenches.
Test Port Status LEDs
Each test port has an "S" and "R" status LED assigned to it. On the left side of the front panel
are the odd numbered port status LEDs, and on the right side are the even numbered port
status LEDs. The "S" indicates Source mode and "R" indicates Receiver mode for that test
port. An illuminated LED indicates that the port is active in either the Source (output) or
Receiver (input) path mode. In S-Parameter measurement mode S33, for example, both the
"S" and "R" status LEDs for Test Port 3 will be illuminated, since Port 3 is both outputting a
source signal and receiving a reflected measurement signal.
