Intermodulation distortion measurements
(S93087B/A)
PNA-X PNA PNA-L
The intermodulation distortion (IMD) application makes it
very easy to set up and calibrate swept-IMD measurements
of both amplifiers and frequency converters. It controls the
frequency and power of internal and external sources and
tunes the receivers to the main tones as well as the IMD
products in a single measurement channel. The user can sweep
either the center frequency of the two stimulus signals, the
frequency spacing of the two stimulus signals about a fixed
center frequency, or the power of one or both stimulus signals
or the power of the LO signal. The analyzer can measure
intermodulation distortion products of order 2, 3, 5, 7, or 9,
and can display the associated intercept points. In addition, an
IM Spectrum mode gives a spectrum-analyzer-like display for
confirming or trouble-shooting measurements. Not available with
PNA Options 200, 210, 400 and 410. When configured with a
2-port PNA or 2-port PNA-X with either Option 201, 217, or 219,
an external signal generator and a combiner are required. When
configured with a 4-port PNA or 4-port PNA-X with Option 401,
417, or 419, the two internal sources and an unused test port
coupler configured as a combiner can be used for two-tone IMD
measurements. When configured with PNA-X Option 22x or 42x,
the two internal sources and internal combiner can be used for
two-tone IMD measurements.
Source phase control (S93088B/A)
PNA-X PNA PNA-L
This application allows users to set calibrated, arbitrary phase
differences between two signal sources. The sources can be the
analyzer’s internal sources or external signal generators routed
through the analyzer’s test set. The phase difference can be
fixed, or swept between two specified phase values. Option 088
also controls the relative power level between the sources using
the receiver-leveling feature. Option 088 is targeted for active-
load control, where the analyzer provides a precise, electronically
settable impedance to the output port of a device, while gain and
output power are measured. This capability can be combined
with external load-pull software to create traditional load-pull
power contours. Not available with PNA Options 200 and 210.

Vector and scalar mixer/converter measurements
(S93083B/A)
PNA-X PNA PNA-L
This application includes the scalar mixer/converter plus phase
(SMC+Phase) measurement class that provides fully calibrated
conversion gain/loss, relative phase, and absolute group delay
measurements of mixers and converters without the need for
reference or calibration mixers. Eliminating the calibration
mixer requires a U9391C/F/G comb generator
1
and an external
DC power supply capable of sourcing +15 V and 300 mA for
U9391C/F or 800 mA for U9391G. A vector mixer/converter
measurement (VMC) class is also included for measuring the
phase difference between multiple paths or devices, or for
measuring phase shifts within a device. Using VMC or the
comb-generator-based calibration for SMC+Phase requires an
instrument with a configurable test set (i.e., has front-panel RF
loops). For units without front-panel loops, SMC+Phase can be
used with a calibration mixer supplied by the user. S93083B/A
provides an intuitive and easy-to-use user interface for setting
up mixer and converter measurements, with single or dual
conversion stages. It can control the analyzer’s built-in source(s)
as well as external signal generators for use as LO signals.
Supported external sources include the Keysight ESG, PSG,
EXG, and MXG Series, as well as other SCPI-controlled signal
generators. S93083B/A is a superset of S93082B/A, so they
should not be installed together. S93083B/A is compatible with
S93084B/A, which enables measurements of converters with
internal LOs.
Embedded LO capability (S93084B/A)
PNA-X PNA PNA-L
This application tunes the analyzer’s receivers to the output
frequency of the converter under test without the need for
access to internal LOs or a common reference signal. S93084B/A
is intended to work with S93029/082/083/086/087B/A
measurement applications.
Gain compression measurements (S93086B/A)
PNA-X PNA PNA-L
The gain compression application (GCA) provides input power,
output power, gain, and phase at the compression point of an
amplifier or frequency converter, over a specified frequency
range. GCA's SMART Sweep is very fast and easy-to-use. GCA
also includes a guided calibration that corrects for absolute
power levels, frequency response, and mismatch errors.
