Drive down the size of test
When you need to measure basic S-parameters,
the right mix of speed, performance and footprint
gives you an edge. Sharpen your edge with the
Keysight PXI vector network analyzer (VNA), ideal
for:
•
•
•
•
Electronic calibration (ECal): enables fast,
easy and accurate calibrations
Maintain hardware compliance
The M937xA is PXI compliant and designed to
benefit from fast data interfaces. The PXI VNA can
be integrated with other test and automation
modules in either a PXIe or Hybrid slot. The PXI
format offers high performance in a small, rugged
package. It is an ideal deployment platform for
many automated test systems.
Wireless manufacturing test

Aerospace/defense manufacturing test
Get more VNA in less space
The Keysight PXI VNA is a full two-port VNA that
fits in just one slot. The PXI VNA also performs
fast, accurate measurements and reduces your
cost-of-test by letting you simultaneously
characterize many devices -- two-port or
multiport -- using a single PXI chassis.
It offers the best PXI VNA performance on key
specifications such as dynamic range,
measurement speed, and trace noise. Each
module is a completely independent two-port
network analyzer and up to 16 modules can be
added to a chassis for multi-site and multiport
applications. All ports are fully synchronous so
multiple ports can be measured simultaneously
with multiport error correction applied. For more
information, see page 28.
Achieve confidence and continuity in
measurements
The M937xA extends Keysight’s expertise in
metrology to the modular form factor. It provides
the same quality results you have come to expect
in our vector network analyzers. Here are a few
examples of ways that we continue to provide
measurement quality and continuity.

Definitions
Specification (spec.)
Warranted performance. Specifications include guardbands to account for the expected statistical performance
distribution, measurement uncertainties, and changes in performance due to environmental conditions. All
specifications and characteristics apply over a 25°C ±5°C range ambient and module temperature between 33°C to
46°C (unless otherwise stated). The following conditions must be met:
§ Instrument has been turned on for 60 minutes with PXI VNA application running.
§ Instrument is within its calibration cycle.
§ Instrument remains at a stable surrounding environment temperature (between -10°C to 55°C) for 60 minutes
prior to turn-on.
Characteristic (char.)
A performance parameter that the product is expected to meet before it leaves the factory, but that is not verified in
the field and is not covered by the product warranty. A characteristic includes the same guardbands as a specification.
Typical (typ.)
Expected performance of an average unit at a stable temperature between 25°C ±5°C for 60 minutes prior to turn-on
and during operation; does not include guardbands. It is not covered by the product warranty. The instrument must be
within its calibration cycle.
Nominal (nom.)
A general, descriptive term or design parameter. It is not tested, and not covered by the product warranty.
Calibration
The process of measuring known standards to characterize an instrument's systematic (repeatable) errors.
Corrected (residual)
Indicates performance after error correction (calibration). It is determined by the quality of calibration standards and
how well "known" they are, plus system repeatability, stability, and noise.
Uncorrected (raw)
Indicates instrument performance without error correction. The uncorrected performance affects the stability of a
calibration
Temperatures referred to in this document are defined as follows:
§ Full temperature range = individual module temperature of 10°C to 70°C, as reported by the module, and
environment temperature of 0°C to 55°C.
§ Controlled temperature range = individual module temperature of 33°C to 46°C, as reported by the module, and
environment temperature of 20°C to 30°C.
Frequency break points
For all tables in this data sheet, the specified performance at the exact frequency of a break is the degraded value of
the two specifications at that frequency, unless otherwise indicated.

Noise floor in a 10 Hz IF bandwidth
System dynamic range = source maximum output power minus receiver noise floor at 10 Hz IF
bandwidth. Does not include single module crosstalk effects.
2
System dynamic range = source maximum output power minus receiver noise floor at 10 Hz IF
bandwidth. Does not include single module crosstalk effects.
3
Effective dynamic range is when the crosstalk is greater than the noise floor, and thus crosstalk limits
the dynamic range. Crosstalk only limits the dynamic range for IF bandwidths < 1 kHz.

Multiport / Multisite operation
Please refer to the relevant literature for more information on Multiport/Multisite operation. The
installation guide and help file are on the CD that was shipped with the PXI module and at:
http://na.support.keysight.com/pxi/help
§ Ordering information:

§ Hardware configuration: Installation Guide
§ Software configuration: M937xA Help file.
Multiport (Option 551)
The PXI VNA modules have the ability to be configured into a multiport network analyzer. Adding a
second module to the PXI chassis would enable a four port vector network analyzer, and for each
subsequent PXI VNA module which is added, it provides two additional test ports to the VNA. This
configuration provides a full featured multiport vector network analyzer capability with full crossbar Sparameter measurement capability.
Configurations of up to 16 modules with 32 test ports have been demonstrated.
For four-port operation, all specifications apply except cross-module trace noise. Cross-module trace
noise cannot be tested on individual modules. However, four-port trace noise performance will typically
meet the two-port specifications.
Modules are designed and characterized to allow multiport operation beyond four ports, but
performance is not warranted.
Anticipated Nominal Multiport Performance
The guidance provided here is given as general reference based on Keysight’s internal evaluation of
multiport PXIe VNA configurations. Every PXIe VNA card is tested as an individual 2-port VNA to meet
or exceed the performance parameters defined within the data sheet. Multiport setups using multiple
PXIe VNAs are not tested as a multi-port instrument in the factory.
In the table below:
•
A check mark, ü, indicates the performance parameter is the same as the corresponding 2-port
performance.
•
A filled in square, ■, indicates nominal performance parameter that is anticipated to meet 2port performance.
•
An empty diamond, ◊, indicates that the performance parameter may be degraded as the
number of ports increases.

Multisite operation
Multi-site operation is the ability to configure multiple independent PXI VNAs to operate independently
in a single PXIe chassis. Up to ten independent PXI VNA instances have been demonstrated, allowing
parallel testing of devices. Each instance of an independent PXI VNA can have different number of
ports, and can be triggered synchronously, or asynchronously.
More than four independent PXI VNAs operating on a single controller may experience some
degradation in performance due to processing limitations.

Interpolated error correction
With any type of accuracy enhancement applied, interpolated mode recalculates the
error coefficients when the test frequencies are changed. The number of points can
be increased or decreased and the start/stop frequencies can be changed, but the
resulting frequency span must be a subset of the original calibration frequency
span.
