U3047AM08

Introduction

U3047AM08

Description

The Keysight U3047AM08 is a Multiport Test Set that adds 8 ports to extend

the 4-port network analyzer to 12 full crossbar test ports with N-Port

calibration capability.

The Keysight U3047AM08 has the following key features:

— 8 test ports (1.85 mm male connectors)

— Low Loss Mechanical RF switching

— Frequency Range of Operation: 10 MHz - 67 GHz

— Test Set I/O interface for operational control with the network analyzer.

Option 551 is required for N-port calibration. An external personal computer

is not required.

— A standard Keysight System II instrument cabinet (4EIA height x 497.8 mm

depth.

The N5245/47A PNA-X network analyzer will be referred to throughout this

document as the PNA-X. The U3047AM08 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 may exhibit uncertainty ripple residing on the measurement response. Due

to a different number of RF switches in each test port signal path, the maximum cumulative

switch repeatability you may experience for a system test port is indicated in the following table.

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.

Description

Network Analyzer Requirements

Ensure that the network analyzer has the latest version of firmware installed.

The following web site links provide the necessary information needed:

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

— Network Analyzer Firmware -

http://na.support.keysight.com/pna/firmware

— U3047AM08 Test Set Files -

http://na.support.keysight.com/multiport/testsetsupport.html

Table 3

All network analyzers require Option 551 for multiport operation (N-Port error

correction and measurement capability). Table 3 provides a listing of other

network analyzer option requirements. The network analyzer’s frequency range

must be equal to or exceed that of the test set so that the measurement

system covers the full frequency range of the test set.

The test set files indicated in Table 3 must be installed into the analyzer’s file

directory: c:\Program Files\Keysight\Network Analyzer\testsets

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 90. Keep the

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

representative.

General Specifications

Specifications for the test set are characteristic for the system performance of

the network analyzer and the test set. Before using the network analyzer and

test set a calibration is recommended for best measurement performance.

Actual performance of the system is based on the customer’s network analyzer

and options that are used with the test set. A functional certificate is only

offered for the test set.

When connected to a network analyzer, this test set will degrade the

performance at the test ports. The internal switch paths reduce test port power

and power to the receivers. This affects the test port power of the network

analyzer and also reduces dynamic range. The reflection tracking values

measured in the “Cal Kit Operational Check” on page 55 can be subtracted

from the analyzers dynamic range to determine the approximate performance

of the system.

Power Requirements

Verify that the required ac power is available before installing the test set to the

network analyzer.

— 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 network

analyzer.

— N5245A and N5247A maximum power is 450 W.

— U3047AM08 maximum power is 350 W.

This is a Safety Class I Product (provided with a protective earthing

ground incorporated in the power cord). The mains plug shall be only be

inserted in a socket outlet provided with a protective earth contact. Any

interruption of the protective conductor inside or outside of the product

is likely to make the product dangerous. Intentional interruption is

prohibited.
