U3050BH11 Introduction

Introduction

This document describes how to use and service the U3050BH11 Amplifier Combiner

Test Set for with the Keysight N5245A PNA-X.

Definitions

•Specifications describe the performance of parameters covered by the product warranty

(temperature of 0 to 40 °C, unless otherwise noted.)

•Typical describes additional product performance information that is not covered by the

product warranty. It is performance beyond specification that 80% of the units exhibit with a

95% confidence level over the temperature range 20 to 30 °C. Typical performance does not

include measurement uncertainty.

•Nominal values indicate expected performance or describe product performance that is

useful in the application of the product, but is not covered by the product warranty.

•Characteristic Performance describes performance parameter that the product is expected to

meet before it leaves the factory, but is not verified in the field and is not covered by the

product warranty. A characteristic includes the same guard bands as a specification.

Keysight U3050BH11 User's and Service Guide

U3050BH11 Description

Description

The Keysight U3050BH11 Test Set uses two amplifiers for increased power and a coupler to

combine power from the N5245A Ports 1 and 3 for high power applications. Five bulkhead

access connectors allow for custom configurations and minimizes connections to the PNA-X.

These connections are RCVR R1 IN, PORT 1, SOURCE OUT, DUT OUT, and PXA (2.4 mm

female connectors).

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 43. Keep the damaged shipping

materials (if any) for inspection by the carrier and an Keysight Technologies representative.

Network Analyzer Requirements

The N5245A PNA-X Network Analyzers will be referred to throughout this

document as the PNA-X. The U3050BH11 will be referred to as the Test Set.

U3050BH11 General Specifications

General Specifications

Specifications for the Test Set (2 GHz to 50 GHz) are characteristic. A functional certificate is only

offered for the Test Set. There are no system specifications.

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 instrument 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 2 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.

U3050BH11 General Specifications

Environmental Requirements

Refer to the PNA-X 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 maximum relative humidity of 95%, non-

condensing to temperatures up to 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 2.

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.

U3050BH11 General Specifications

Maximum Power Levels

It is recommended that you do not operate components near damage levels

(+30 dBm). The power levels must be 3 dB below maximum level to ensure

no damage, see Table 4.

Refer to your PNA-X specifications to determine the maximum input power

levels for the access and test ports, or to optimize the power levels in the

receivers.

Damage and maximum levels are not necessarily the optimum level.
