U3020AD01 Introduction

Introduction

This document describes how to use the Keysight U3020AD01 Dynamic Accuracy Test Set with

a Keysight N5247A PNA-X Network Analyzer.

Figure 1 N5247A with the U3020AD01

User’s and Service Guide U3020-90004 3

U3020AD01 Description

Description

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

Network Analyzers and based on the L4490A RF Switch Platform.

The U3020AD01 is used to characterize the PNA-X power linearity (dynamic accuracy)

designed for maximum measurement accuracy over a 110 dB dynamic range. The signal is

controlled via internal attenuators.

The U3020AD01 can only be controlled using an external GPIB controller or LAN.

When using Keysight IO Libraries "Connection Expert Utility," the interface identifies the Test

Set as "U3020A" without D01. D01 will be listed on the rear panel serial tag.

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 34. Keep the damaged

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

representative.

Network Analyzer Requirements

• The N5247A PNA-X Network Analyzer (10 MHz to 67 GHz)

More PNA-X information is available on the following websites:

• Documentation - http://www.keysight.com/find/pna

• Network Analyzer Firmware - http://na.support.keysight.com/pna/firmware

U3020AD01 General Performance

General Performance

The Test Set is used to characterize the power linearity of the PNA-X. Actual performance of the

system is based on the your PNA-X and options that are used with the Test Set. It is not

specified as an 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.

CAUTION 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 to the PNA-X.

• 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.

•Table 1 contains the maximum wattage for the Test Set. This table can be use to determine

the electrical and cooling requirements.

U3020AD01 General Performance

Environmental Requirements

Refer to the PNA-X standard 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.

Maximum Power Levels and Performance Characteristics

NOTE 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.

NOTE Damage and maximum levels are not necessarily the optimum level.
