Satellite Signal Monitoring Test Challenges
Today’s satellite systems must deliver more complex data streams to and from ground
stations than ever. Technologies such as spot-beams, add to the complexity. The process
of monitoring such massive multiband, multi-frequency satellite data streams becomes
a multifaceted measurement challenge. Most monitoring configurations consist of a
dedicated test set allocated to a specific band or frequency. For many satellite earth
stations that means a room full of fixed hardware and the resources to support it. Going
forward, a test solution that consolidates multiple measurement instruments into a
single unit, whenever possible, has the potential to reduce size and conserve resources.
Evolving measurement solutions should be multifunctional across multiple bands and
modulation formats, and be integrated into as compact a footprint as possible.
Monitoring satellite communication signals brings many challenges:
–– Satellite manufacturers, operators and service provides need methods to ensure
optimal satellite spectrum utilization
–– Each satellite band may contain several carriers each with different modulation
format and symbol rate
–– The latest high throughput satellites, which combine many channels onto a single
transponder, result in the need to monitor wider bandwidth signals and adds new
measurement requirements.
–– Interfering carriers need to be detected and identified
–– Geographically dispersed monitoring stations require remote access and control.
Compact, easy to transport solutions improve deployment and maintenance.
Satellite Signal Monitoring, Reference Solution
The Satellite Signal Monitoring, Reference Solution is a combination of hardware,
software, and measurement expertise providing the essential components of a satellite
ground station monitoring system. This enables engineers to use, enhance, or modify
the test system as required to meet specific test application needs including flexible
hardware configurations, carrier power monitoring, detailed modulation analysis
for deterministic signals, measurement results logging, and cross-band timing
measurements.
Built upon a modular instrument format (PXIe) its attributes include excellent instrument
density, expandable multichannel support and high data bus speeds, ideal for multiband monitoring. To provide flexibility, a choice of vector signal analyzers (M9391A and
M9393A) is available to tailor the system frequency ranges as needed. In addition,
Keysight’s 89600 VSA software provides the spectrum analysis and digital demodulation
tools required for this application. To facilitate integration in your test environment, you
can use the measurement setup files, and test code logging and 89600 VSA software
automation layer examples to customize your signal monitoring solution.

Reference Solution Architecture
The flexibility and performance of modular PXIe instrumentation provides a scalable
platform that is ideal for satellite signal monitoring applications. Two common
configurations are shown below.
Sequential Scanning Configuration
The sequential scanning model is ideally suited for applications requiring the monitoring
of several, non-overlapping bands. With this configuration, several bands can be
monitored at once with a single M9393A PXIe Vector Signal Analyzer which historically
required multiple sets of analyzer hardware. An M9391A PXIe VSA could also be used
if the signals are first down-converted at the antenna. Using a single analyzer results
in lower weight and power and provides a cost-effective solution that can be scaled as
needs change (including room in the chassis to integrate in other PXI modules such as RF
and microwave switches).

Parallel Acquisition Configuration
The parallel acquisition configuration utilizes multiple PXIe Vector Signal Analyzers
and simultaneous acquisitions for all bands. This configuration is well-suited for cases
where spectrums overlap including cases where multiple dishes are using block down
conversion to an IF band. Depending on frequency, either the M9391A or M9393A could
be used (as well as a mixture of the two). This configuration also provides improved
scanning speed and allows for cross-timing measurements such as uplink to downlink
timing (timing synchronization between channels is 1ns).

Software
www.keysight.com/find/89600vsa
The reference solution is built upon Keysight’s 89600 VSA software. The 89600 VSA
software is the industry’s premier vector signal analysis software for evaluating complex
signal spectrum, modulation and time characteristics. Custom data/measurement
logging programs can then be built upon the 89600 VSA automation layer and interface
to the software via the standard .NET API. This API supports the complete set of 89600
VSA software features and options.

Software – Signal Analysis
Stepped spectrum analysis (89601B-SSA)
The 89600 VSA software, Option SSA, performs traditional power spectrum measurements across a selected frequency range within the PXIe VSA’s operating range, from
1 MHz to 6 GHz (M9391A) or 9 kHz to 27 GHz (M9393A). With Option SSA, you choose
your measurement settings. Based on these settings, the analyzer performs a rapid
sequence of FFT-based spectrum measurements at frequency steps across the span.
These results are then merged into a single, continuous spectrum.
Unlike other stepped-FFT spectrum analyzers, 89600 Option SSA insulates the user from
the inherent complexity of the measurement. Critical, low-level settings are automatically optimized by the software but still accessible to the advanced user. The innovative
software architecture assigns hardware acquisition and measurement processing to separate execution threads in order to maximize measurement speed. When combined with
the multi-measurement mode capability (described below), multiple frequency bands
can be scanned in either the sequential or parallel configurations.

07 | Keysight | Satellite Signal Monitoring Reference Solution - Solution Brochure
Modulation analysis (89601B-AYA)
The 89600 option AYA is designed to analyze a wide range of digital modulation formats
and standards with presets for many aerospace, defense and satellite applications including AM, FM, PM, BPSK, QPSK, QAM, APSK, FSK, VSB, SOQPSK, APCO 25.
The advanced digital demodulators allow you to successfully demodulate a signal knowing just the carrier frequency, filter type, and symbol rate; no need for external filtering,
coherent carrier signals or symbol-clock timing signals. Flexible measurement parameter setup, powerful error analysis, including EVM, and insightful displays help explain
every aspect of a signal.

Option AYA.
Multi-measurement mode
The multi-measurement capability allows you to configure, execute and display several measurements at once, simplifying and speeding analysis of multi-carrier signals or
simultaneous uplink and downlink signals. For example, you can set up a test sequence,
including a wide spectrum scan and multiple demodulation measurements, to run concurrently. You can also configure the data acquisition mode to be synchronous (default)
or sequenced to speed up measurement switching time from one to another. When all
signals fit within the PXIe VSA’s analysis bandwidth, multiple measurements are performed on the data from a single acquisition, ensuring the measurements are perfectly
simultaneous. For wider frequency coverage, or in the case of the parallel configuration,
the 89600 VSA software can coordinate up to four independent PXIe VSAs to acquire all
desired signals. Alternately, multiple instances of the 89600 VSA software can be run at
once, one for each instrument.

3 signals at once.
As these tests are configured, they are held in memory in pre-built, ready-to-execute
form. A single command initiates the sequence, causing the 89600 VSA software to step
rapidly through the measurements with no further operator intervention.
Software – Example Software
89600 VSA software setup files
Example 89600 VSA software measurement setup files illustrating the multi-measurement capability (including a four-band sequenced configuration) are included. When
used with the M9393A PXIe VSA and a suitable vector signal generator (VSG), such as
the Keysight M9381A PXIe VSG, these setups along with the M9381A demo waveform
provided, can be used as an example to building custom measurement setups.
Data logging example program
An example data logging program (including C# source code) is included which helps
illustrate how to use the 89600 VSA software .NET API to automate satellite signal
monitoring. The demo program uses the same M9381A PXIe VSG demo waveform as the
setup file. This logging program performs the following functions:
–– Cycles between a power spectrum trace and three digital demodulation
measurements
–– Compares carrier power to predefined limits
–– Continually logs measurement results to a file (with time stamps).
