U3020AD01 Introduction

Introduction

This document describes how to use and service the Keysight U3020AD01 Dynamic Accuracy

Test Set.

Figure 1 U3020AD01 Dynamic Accuracy Test Set

Keysight U3020AD01 User's and Service Guide

U3020AD01 Description

Description

The Keysight U3020AD01 Dynamic Accuracy Test Set is designed for the Keysight PNA-X

network analyzer as a test accessory in performing the power linearity test (dynamic accuracy)

of the network analyzer receivers. As of this manual edition, other Keysight network analyzer

product families have also incorporated the Test Set in their production and service processes.

The U3020AD01 Test Set can only be controlled via the rear panel GPIB or LAN interfaces.

When using the Connection Expert utility program, available on the PNA-X platform and other

computer platforms, the program may identify the Test Set as "L449XA" or "U3020A." The full

Test Set model number can be found on its rear panel serial label.

For more PNA-X network analyzer Dynamic Accuracy measurement information, refer to the

PNA-X Service Guide for the model you have: http://www.keysight.com/find/pna

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 35. Keep the damaged

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

representative.

U3020AD01 General Performance

General Performance

The Test Set is used to characterize the receiver power linearity of a network analyzer. Actual

performance of the system is based on your network analyzer and options that are used with the

Test Set. The Test Set is not specified for overall system performance. A functional certificate is

supplied for the U3020AD01.

There are no internal adjustment in the U3020AD01, therefore an annual calibration is not

required.

This product has an autoranging line voltage input. Be sure the supply

voltage is within the specified range.

Power Requirements

Verify that the required AC power is available at all necessary locations before installing the

Test Set and Network Analyzer.

•100-240 V (50/60 Hz)

•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.

•U3020AD01 maximum power is 50 W.

Keysight U3020AD01 User's and Service Guide

U3020AD01 General Performance

Environmental Requirements

Refer to the Network Analyzer documentation for environmental requirements.

Environmental Tests

The U3020AD01 complies with all applicable safety and regulatory requirements for the

intended location of use.

•Operating Environment (Indoor Use)

•Operating Ambient: Temperature 0 to 40 °C

•Operating Altitude: 0 to 2000 meters (~ 6,562 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 rating listed in the

PNA standard documentation.

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 U3020AD01 and PNA includes configuration and installation on a

customer provided lab bench or table top of adequate size and strength.

General Performance

Refer to your PNA-X standard documentation specifications to determine the

maximum input power levels for the PNA-X access and test ports, or to optimize

the power levels in the receivers.

Damage and maximum levels are not necessarily the optimum level.
