Additional options

□ Pulse measurements (Option H08)

This option provides software to set up and control pulsed-RF

measurements with point-in-pulse and pulse-profile capability.

The software sets the coefficient of the PNA-X’s digital-IF filters

to null out unwanted spectral components, enables the receiver

IF gates on the rear panel, controls internal pulse generators

(Option 025), internal pulse modulators (Option 021 and/or 022)

or external pulse modulators, and optimization for measurement

sensitivity. The measurement software can run on the PNA-X

or an external computer. A “.dll” file containing the IF-filter

algorithms is included for automated pulsed-RF testing. The

N1966A pulse I/O adapter is recommended if using external

pulse generators and/or external pulse modulators.

□ Time domain (Option 010)

This option enables the PNA-X to view reflection and

transmission responses in time or distance. Use time domain

to tune filters, gate out the response of fixtures and cables,

characterize the impedance of transmission lines and more.

□ Add IF inputs for antenna and millimeter-wave (Option 020)

This option enables external IF inputs on the rear panel of the

PNA-X for applications such as antenna and millimeter-wave

test.

□ Add pulse modulator to internal first source (Option 021)

This option enables the internal pulse modulator on source 1.

Control of the modulator can also be done via pin 8 of the

Pulse I/O D-sub connector on the rear panel of the PNA-X

using an external pulse generator, or by using one of the internal

pulse generators (Option 025). The N1966A pulse I/O adapter

is recommended if using an external pulse generator.

(See diagram below for details of the D-sub connector.)

□ Add pulse modulator to internal second source (Option 022)

This option enables the internal pulse modulator on source 2.

Control of the modulator can also be done via pin 8 of the

Pulse I/O D-sub connector on the rear panel of the PNA-X

using an external pulse generator, or by using one of the internal

pulse generators (Option 025). The N1966A pulse I/O adapter

is recommended if using an external pulse generator. Option 224

or 400 required. (See diagram below for details of the D-sub

connector.)

□ Add four internal pulse generators (Option 025)

This option enables four internal pulse generators. These

pulse generators can be used to control the internal pulse

modulators and internal receiver IF gates, and are also available

on pins 10 through 13 of the Pulse I/O D-sub connector on

the rear panel of the PNA-X to control external modulators

and/or gates. The N1966A pulse I/O adapter is recommended

if using external pulse modulators. (See diagram below for

details of the D-sub connector.)

□ Fully-corrected noise figure measurements (Option 029)

This option adds hardware and firmware for high-accuracy

noise figure measurements, utilizing Agilent’s unique source-

correction technique. Using the PNA-X and an Agilent ECal

module configured as an impedance tuner, the effects of

imperfect system source match are removed, greatly improving

the accuracy of the cold-source technique. This approach

surpasses the accuracy provided by the Y-factor method. This

option requires an N4691B ECal module (m-f recommended)

and a 346-series noise source (both must be ordered or supplied

separately). During calibration of the analyzer, an additional

ECal or mechanical calibration kit is required (also must be

ordered or supplied separately). The noise source is only used

during calibration of the analyzer. To use the ECal module as a

tuner, Option 029 includes a cable (N5242-20137) and 3.5 mm

m-f adapter (85052-60013) for use with m-f modules

(N4691B-M0F). For use with f-f ECal modules (N4691B-00F),

order a 3.5 mm m-m adapter (85052-60014).

□ Frequency offset (Option 080)

This option enables the PNA-X to set the source frequency

independently from where the receivers are tuned. This ability

is important for measuring amplifiers, mixers, and frequency

converters.

□ Scalar-calibrated converter measurements (Option 082)

With a simple setup and calibration, this application delivers

the highest accuracy for conversion-loss (or gain) magnitude

measurements by combining one-port and power-meter

calibrations to remove mismatch errors. This application

provides an intuitive and easy-to-use user interface for setting

up mixer and converter measurements, with single or dual

conversion stages (up to two local oscillators, LO), along with

control of up to two external signal generators for use as LO.

External synthesizers supported include the Agilent ESG series

and the PSG series of signal source families as well as other

SCPI controlled signal generators. Option 082 requires Option 080,

and cannot be ordered with Option 083.
