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, character-
ize 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 millime-
ter-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 Keysight’s unique source-correction
technique. Using the PNA-X and a Keysight 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 inde-
pendently from where the receivers are tuned. This ability is import-
ant 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 mea-
surements 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 Keysight 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.
