PNA Family Microwave Network Analyzers

(N522x/3x/4xB)

Introduction

This configuration guide describes standard configurations, options, accessories, upgrade kits and compatible peripherals for the PNA Family microwave network analyzers. This guide should be used with the Keysight Technologies, Inc. PNA Family data sheets for a complete description of these analyzers.

Keysight Offers the Following Options for All PNA Family Network Analyzers

ANSI Z540 compliant calibration (Option A6J)

Complete set of measurements which tests unit to manufacturer’s published specifications. Includes pre- and post-adjustment data with measurement uncertainty information compliant to the ANSI/NCSL Z540 standard.

Documentation

The PNA Series instruments are equipped with an Online Help system available within the instrument in English only. All PNA documentation is available on the web: www.keysight.com/find/pna

Calibration software licenses

Built-in performance test software for standard compliant cal (S93898B)

Adds built-in performance testing and calibration software for self-maintainers. Requires additional equipment. See the analyzer’s Service Guide for more information on equipment required.

PNA-X Series Test Set and Power Configuration Options

The PNA-X is an integrated vector network analyzer featuring a built-in S-parameter test set, one or two synthesized sources used for device stimulus, a solid-state drive, USB interfaces, and a 12.1” LCD touch screen display. The N5241B, N5242B, and N5249B have 50-ohm, ruggedized 3.5 mm (m) test ports. The N5244B and the N5245B have 50-ohm, ruggedized 2.4 mm (m) test ports. The N5247B has 50-ohm, ruggedized 1.85 mm (m) test ports. Included with each instrument is a mouse, keyboard (U.S. style), and one day of on-site productivity assistance (PS-S20-PNA).

The block diagrams shown below include hardware that must be ordered as separate options, such as pulse modulators (Options 021 and 022), and IF access (Option 020), or is controlled by application software, as is the case for the pulse generators. In addition, the combiner type and attenuator values vary by model number. Refer to the product data sheet for the correct block diagram for a specific model.

A test set and power configuration option is mandatory, choose one of the following:

2-ports, single source, with configurable test set (Option 201)

The standard 2-port test set comes with six front-panel access loops. The loops provide access to the signal path between (a) the source output and the reference receiver, (b) the source output and directional coupler thru arm and (c) the coupled arm of the directional coupler and the port receiver. The standard test set also includes a solid-state internal RF bypass switch in the R1 reference-receiver path.

2-ports, single source, with configurable test set and low frequency extension (Option 205)

Along with 2-port single source with the access loops with Option 201, Option 205 adds bias tees and additional hardware to extend the start frequency of the PNA-X down to 900 Hz.

The extended start frequency is available only for the following measurement classes: standard, gain compression (amplifier and converters), and for magnitude-only measurements using SMC (scalar mixer/converter) or SMC+Phase. In the standard channel, pulsed RF, true-mode stimulus, and source phase control are not supported for measurements below 10 MHz. The block diagram below shows how the low-frequency hardware is configured for one test port; the other test ports are configured similarly. For test port 1, the combiner and noise tuner (not shown) are only available for use down to 10 MHz, and for test port 2, the low-noise receiver (not shown) is only available for use down to 10 MHz.

2-ports, single source, with extended power range and bias-tees (Option 219)

This configuration comes with front-panel access loops, and bias tees and source and receiver attenuators at each port. The source attenuators are settable in 5 dB steps up to 65 dB in N5241/42/49B, in 10 dB steps up to 60 dB in N5244/45B, and in 10 dB steps up to 50 dB in N5247B. The receiver attenuators are settable in 5 dB steps up to 35 dB in N5241/42/44/45/49B, and 10 dB steps up to 50 dB in N5247B. The bias tees are connected directly to the test port couplers, which limits the maximum power rating on the pair to +30 dBm (additional attenuators or isolators are typically required to protect other components inside the instrument).

2-ports, dual sources, with extended power range, combiner, and mechanical switches (Option 222)

Along with the access loops and attenuators of Option 217, Option 222 includes an internal second source, a combiner, mechanical switches, and more access loops. The internal second source provides an additional signal (fixed or swept) for two-tone intermodulation testing of amplifiers, or for use as a local oscillator for testing mixers and frequency converters. The mechanical switches switch the combiner in and out as needed, as well as enabling the additional access loops for advanced configurations. The second source is available through two RF connectors on the front panel, from port 1 when combined with source 1, or via rear-panel access loops. The maximum power rating on the test port couplers is +43 dBm (additional attenuators or isolators are typically required to protect other components inside the instrument). Option 222 is not available on the N5247B. To independently control the frequency of the second internal source, one of the following software applications is required: S93080/029/ 070x/082/083/084/086/087/089/090x/093/094B.
