Spectrum analysis (S93090xB/A)
PNA-X PNA PNA-L
The spectrum analyzer (SA) application adds high-performance
microwave spectrum analysis to PNA-X, PNA, and PNA-L Series
network analyzers. With fast stepped-FFT sweeps resulting from
optimized data processing, the SA application provides quick
spurious searches over broad frequency ranges. Simultaneous
spectrum measurements can be done using up to five test and
reference receivers. This multi-channel SA can be used with
the internal swept-signal generators for efficient measurements
of spurious signals emanating from mixers and frequency
converters. The SA application employs source-power and
receiver-response calibration as well as fixture de-embedding,
providing in-fixture and on-wafer spectrum measurements with
the highest level of accuracy. Accurate and fast noise power ratio
(NPR) measurement capability is also included in this software
application. It provides the ability of setting up and controlling
of external signal generator/arbitrary waveform generators and
performing the calibration of the flatness of a wideband signal
and distortion signals in notches, and achieving very fast NPR
measurements. It is recommended to use this option with PNA
or PNA-X instruments with internal receiver attenuators to avoid
receiver compression when measuring large signals. For use with
PNA-L models, test set option 216 or 416 is recommended so
that external attenuators can be connected via the front-panel
jumpers to avoid receiver compression. The upper frequency
range of the SA application is determined by the installed SA
license or the stop frequency of the instrument, whichever
is smaller. There are several frequency choices intended for
standalone instruments: S930900B/A to 8.5 GHz, S930901B/A to
13.5 GHz, S930902B/A to 26.5 GHz, S930904B/A to 43.5 GHz,
S930905B/A to 50 GHz, and S930907B/A to 67 GHz. Intended
for use with analyzers configured with broadband or banded
millimeter-wave extenders, several more choices are available:
S930909B/A to 90 GHz, S93093B/A to 120 GHz, and S93094B/A
for frequencies above 120 GHz.
Spectrum analysis, up to 120 GHz (S93093B/A)
PNA-X PNA PNA-L
S93093B/A has all of the capability of the S93090xB/A spectrum
analyzer application, with an upper frequency of 120 GHz. It is
intended for analyzers configured with broadband or banded
millimeter-wave frequency extenders, using a millimeter-wave
controller. With this configuration, the analyzer’s internal receiver
attenuators are not in the receiver paths, so they cannot be used
to reduce signal levels. External attenuators may be required to
avoid compressing the receivers in the millimeter-wave frequency
extenders. When using S93093B/A for millimeter-wave spectrum
analysis, an N5261/62A or an N5292A millimeter-wave controller
is required. When S93093B/A is installed on a standalone
network analyzer, it will provide spectrum analysis up to the
frequency limit of the instrument.

Differential and I/Q device measurements
(S93089B/A)
PNA-X PNA PNA-L
This application combines source-phase control of multiple
internal or external sources with frequency-offset mode,
enabling simplified test of I/Q modulators/converters and
differential mixers, and harmonic measurements of differential
amplifiers. The phase difference between sources can be
fixed (for example, at 90 or 180 degrees), or swept between
two specified phase values. Providing accurate control of the
relative phase between sources eliminates the need for hybrid
couplers and baluns to create quadrature or differential signals.
After achieving the desired phase alignment, the instrument’s
receivers can be tuned to all frequencies needed to characterize
the DUT. On an I/Q modulator for example, measurements
can be made of both the desired and suppressed conversion
bands, along with LO leakage, harmonics and other spurious
signals. Phase sweeps can be used to determine a DUT’s phase
imbalance versus frequency. Users can specify measurements
with individual receivers or multiple receivers combined with a
wide range of mathematical operators. Power measurements
can employ match correction for increased accuracy. S93089B/A
only works on 4-port PNA or PNA-X models.
