N5280A

Introduction

The N5280A replaces the 8511A Four Channel Frequency Converter Test Set.

This document describes how to use the N5280A Test Set with the Keysight

N5242A 2-Port, or 4-Port PNA-X Network Analyzer and N5264A Measurement

Receiver.

N5280A

Description

The Keysight N5280A is a four channel frequency converter Test Set. This Test

Set is used with the Keysight N5242A 2-Port or 4-Port PNA-X Network

Analyzer, and a N5264A Measurement Receiver. It can be operated with other

microwave accessories (couplers, power splitters). The N5280A provides a

convenient means of customizing a test configuration for a variety of

applications within a frequency range of 10 MHz to 26.5 GHz. In addition to

configurations for measuring reflection and transmission parameters of

one-port or two-port devices, you can build configurations to characterize

antenna parameters, radar cross sections and frequency translation devices.

Figure 4 on page 9 illustrates one possible measurement set-up configuration.

Network Analyzer Requirements

— The N5242A 2-Port or 4-Port PNA-X Network Analyzer (10 MHz to 26.5

GHz) requires Option 020, which adds IF inputs.

— The N5264A Measurement Receiver requires Option 108, which adds LO

Source 26.5 GHz.

Verifying the Shipment

To verify the contents shipped with your product, refer to Table 1.

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 54. Keep the damaged shipping materials (if

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

Test Set Options

The N5280A has two available Test Set options: 

Refer to Figure 29 on page 43, Figure 30 on page 44 and Figure 31 on

page 45.

— Standard (700) - There are no attenuators in the RF Input paths.

— Option 001 - There are four attenuators (0 to 35 dB) in the RF Input paths to

reduce the power levels.

— Option 002 - There are four IF Channels (A, B, C and D) and LO Input on the

front panel.
