Analog Modulation and Demodulation Overview
Modulation is the process of translating
some low-frequency or baseband signal
(such as voice, music, or data) to a higher
frequency (carrier signal). The primary reasons for modulation include allowing the
simultaneous transmission of two or more
baseband signals by translating them to
different frequencies, and to take advantage of the greater efficiency and smaller
size of higher-frequency antennae.
Analog modulation is the most fundamental modulation method. In analog modulation, the variations to the carrier are
applied continuously in response to the
analog information signal. By definition,
the analog signal is continuous in time
and amplitude, as opposed to a digital or
discrete signal.
A high-frequency carrier signal commonly
has sinusoidal form. There are two properties of a carrier signal that can be altered:
1) the amplitude (A) and 2) the angular
position. Thus, there are amplitude modulation (AM) and angle modulation. Angle
modulation can be further characterized
as either frequency modulation (FM) or
phase modulation (PM).
FM stereo is an enhancement to FM that
uses stereo multiplexing. An FM stereo
signal carries stereophonic programs in
which signals are transmitted for L (left)
and R (right) audio channels. Radio data
system (RDS) consists of the text information such as traffic, weather, and radio
station information carried in the FM signals. This information can be displayed on
the screen of the end-user's device. RBDS
is the United States version of RDS.
* FM stereo/RDS analysis requires N9063A-3FP
Table 1 summarizes these three formats of
analog modulation.
Analog demodulation is a reverse process
of the analog modulation. It offers quantitative assessments for analog modulation
qualities. Analog demodulation is not only
essential in testing FM or AM transmitters,
but is also a powerful troubleshooting tool
for analyzing unintentional signals from
digitally modulated transmitters such as
2G/3G cellular phones, and wireless LAN
and WiMAX™ devices. The FM demodulation measurement is also an excellent
alternative for high-volume manufacturing
of low-price digital wireless devices, such
as Bluetooth®, where test throughput and
manufacturing costs are critical.
The primary targeted markets and use
cases for the analog demodulation measurement application include:
–– Radio transmitter tests
–– Signal generator calibration
–– FM stereo transmitter tests
–– HP/Keysight 8901A/B replacement
–– Incidental modulation analysis (such
as AM to PM, AM to FM, etc.)
–– Transient events and signal
settling time analysis
The analog demodulation measurement
application runs on the Keysight X-Series
signal analyzers and provides fast, complete, and easy-to-use measurements of
AM, FM, PM, or FM stereo/RDS signals.*

of the baseband signal). FM stereo
can view MPX, mono, stereo, left or
right demod waveforms.

view of the baseband signal). FM stereo can view MPX, mono, stereo, left
or right AF spectrum.

clock time, and date)*
Measurement details
Modulation metrics
RF spectrum of the modulated
signal
AM depth
This is the most traditional spectrum analyzer measurement viewing the modulated
carrier signal power in frequency domain.
Prior to being modulated, the signal power
of a sinusoidal carrier concentrates at the
carrier frequency. By contrast, modulation
causes sidebands indicating the power
redistribution over frequencies. The pattern of the sidebands depends upon the
modulation format. (Refer to Figure 2.)
Demod waveform
This measurement retrieves the baseband
signal from the modulated signal via the
demodulation process, and displays the
baseband signal in a pattern of modulation depth/deviation versus time. Since
the modulation depth/deviation is directly
proportional to the instantaneous amplitude of the baseband signal, the measurement result helps to intuitively evaluate
the quality of the baseband signal. (Refer
to Figure 3.)
AF spectrum
By applying the fast Fourier transform
(FFT) to the baseband waveform, this
measurement demonstrates the baseband
signal behaviors in frequency domain
graphically. The AF spectrum reveals the
distortion of the baseband signal clearly
just as the RF spectrum does for the RF
signal. (Refer to Figure 4.)
The AM depth measurement quantifies the
amount of amplitude modulation to which
the baseband signal modulates the carrier
signal. The AM depth, also refers to AM
modulation index (m), and
is defined as:
Emax - Emin
m (in %) =
Emax + Emin
where, Emax and Emin are amplitudes (in
voltage) of the modulated signal at its
peak and trough, respectively, in timedomain. The AM depth ranges from
0 to 100%.
FM deviation
The FM deviation reflects the amount of
the frequency modulation to which the
baseband signal modulates the carrier
signal. The quantity being measured is
the peak frequency deviation that is the
maximum frequency excursion from the
carrier frequency.
Phase deviation
The phase deviation, also referred to PM
deviation, is a measure of the amount of
the phase modulation. The quantity being
measured is the peak phase deviation (in
radians) that is the maximum phase excursion from the average carrier phase.
FM and PM are two forms of angle modulation. They are closely related, as phase
is the time integral of the frequency, and
frequency is the time derivative of phase.
Carrier power
This measures the power of the carrier signal without the modulation. Ideally, power
for a sinusoidal carrier signal is concentrated around its carrier frequency.
* FM stereo/RDS analysis requires N9063A-3FP
06 | Keysight | Analog Demodulation X-Series Measurement Application N9063A & W9063A – Technical Overview
Analog Demodulation Measurements (continued)
Carrier frequency error
SINAD
This measurement reports the difference
between the nominal frequency and the
actual frequency of the carrier. It is only
available for the FM and PM.
The modulation rate quantifies how fast
the modulation is and equates to the
frequency of the baseband signal that
modulates the carrier.
Another commonly used distortion measure is signal to noise and distortion ratio
(SINAD). SINAD, in nature, is the reciprocal
of the modulation distortion provided by
the “distortion/total Vrms,” but the SINAD
is usually expressed in a logarithmic term
as follows:
(P total )½
SINAD (in dB) = 20 × log
(P tota - Psignal )½
Distortion/total Vrms
SNR
Modulation distortion is the undesired alterations added to the modulated signal by
modulation processes. To assess the modulation quality of a transmitter, the modulation distortion needs to be quantified.
Signal to noise ratio (SNR) is defined as
the ratio of total signal power to noise
power:
Modulation rate
Modulation distortion is usually measured
in a relative term against the total signal
power:
(P total - Psignal)½
Modulation
=
× 100%
distortion(in %)
(P total)½
where, P total is the power of the total
signal; Psignal is the power of the wanted
modulating signal; and P total - Psignal is the
total unwanted signal which can be further
divided into the components of noise and
harmonic distortion.
SNR = PSignal /PNoise
However, in practice, when the signal
power PSignal is hard to get, and Pdistortion
and PNoise are substantially smaller than
PSignal. SNR can be approximated as:
SNR ~ (PSignal + Pdistortion + PNoise)/PNoise.
This approximation has been adopted by
HP/Keysight 8903A and therefore inherited
to the N9063A analog demod application.
Figure 2. The RF spectrum view presents the modulated signal along with the results of demodulation.
THD
The total harmonic distortion (THD)
measurement further isolates the total
harmonic distortion component from the
noise component in the total unwanted
signal. It helps the user to troubleshoot
the root causes of modulation distortion.
Other features
Selection of detectors
Four types of detectors are provided: positive peak (Peak+), negative peak (Peak-),
Peak/Peak average ((Pk-Pk)/2), and RMS.
The Max Hold values for each detector are
also displayed.
Comparing the result from the Peak+ detector and from the Peak- detector allows
you to check modulation symmetry. For
symmetric modulation, the Peak+, Peak-,
and the (Pk-Pk)/2 detectors result in identical readings. For asymmetric modulation,
the readings generated by the Peak+ and
Peak- are different, and using the (PkPk)/2 values is recommended.
The RMS detector results in the RMS
(root-mean-square) value of modulation.
It is a good choice when measuring noise
or residual modulation, where the RMS
value is generally more desirable than the
peak value. The RMS detector is also a
good choice for measuring non-sinusoidal
signals.

Analog Demodulation Measurements (continued)
Post-demod filters
The post-demod filters help you to optimize the measurement results by filtering
out undesired signals such as harmonics,
noise, and spurs from the demodulated
signal. You may choose a high-pass filter
(20, 50, 300, or 400 Hz), and/or a lowpass filter (300 Hz, 3, 15, 30, 80, 100, 300
kHz, or any other user defineable) from
the available post-demod filter bank to
achieve the best demodulation results.
For example, applying an appropriate
low-pass filter helps minimize overshoot
from square-wave modulation, such as
frequency shift keying (FSK).
A marker table is added to AF spectrum
view to enable faster and easier analysis of
multi-tone audio (CTCSS, DTMF, etc.), audio flatness response, Command Destruct
telemetry, etc.
Tune and listen*
Listening to the demodulated signal
through a speaker may give you more
insights. Many experts and technicians
can figure out the cause of a problem by
hearing buzzing, humming, and/or clicking
noises.
Additionally, a CCITT filter, which simulates the frequency response behavior of
the human auditory system, is also available to help you evaluate the consequences of distortion of the demodulated signal
from the human hearing perspectives.
The filter bank also allows you to select
from various other filters to optimize your
measurements and comply with certain
regulatory standards. These filters include:
–– A-Weighted
–– C-Weighted
–– C-Message
Figure 3. Apply the "post-demod” filters to optimize analysis results for the baseband (AF) spectrum.
The marker table facilitates the analysis.
–– CCIR-1k Weighted
–– CCIR-2k Weighted
–– CCIR Unweighted
–– SIAND notch
–– Signaling Notch filters
To accommodate your pre-empha-sized
FM signals, the N9063A/W9063A is also
equipped with four separate de-emphasis
filters (25, 50, 75, and 750 μs) for you to
select.
Marker capabilities
The powerful marker capabilities offered
by the N9063A/W9063A further add great
convenience to your analog demodulation
measurements. You can set up to 12 markers and define them as “normal,” “delta,”
or “fixed.”

Accelerating measurements further
The X-Series signal analyzers offer great
advantages in throughput with their
industry-leading speed for measurements
including the analog demodulation. By
turning off the unneeded metrics, the
analog demod measurement application allows you to further speed up your
measurements.
The InfoBW control allows the user to
trade off the bandwidth of the measurement (frequency range of demod) with
the noise in the frequency measurement.
Figure 5, the "Attack/Release view", captures the transient events in time domain
when the modulation starts and the carrier
power switches to different levels.
Quantify the transient events with
"Attack/Release" time view
Attack/Release Time is a new view type
for measuring transient events, such as
“attack” (transmitter turn-on), “release”
(transmitter turn-off), and VCO settling
characteristics. The upper display is RF
Envelope (magnitude) vs. time; the lower
display is FM Demod Waveform (frequency) vs. time. Transient measurements are
single-shot, and require an External trigger edge to establish time t=0 (e.g. from
the PTT button).
Certain measurements from TIA-603 such as Carrier Attack Time, Transient Frequency Behavior, and Encoder Response
Time - are much easier to make with
this new view. The view can be used for
general amplitude and frequency transient
or settling measurements. And transmitters that use FM or FSK in a burst can also
be captured and measured, with RF Burst
trigger.
The view supports long post-demod
waveforms, storing a post-demod FM
Waveform up to 3.6M samples (previously
limited to 1001 pts); this data is available
for query via SCPI. Additionally, limit lines
for FM Waveform can be imported from
customer-defined CSV files and displayed.
Figure 5. "Attack/Release Time" view helps quantify the transient events in time domain.

FM stereo/RDS
MPX view
FM MPX consists of FM signal multiplexing
with the mono signal (L+R), stereo signal
(L-R), pilot signal (at 19 kHz), and optional
RDS signal (at 57 kHz). Figure 5 shows
the FM stereo MPX view with four measurement windows. The top left window
contains RF spectrum, the bottom left
contains MPX AF spectrum, the top right
contains MPX demodulated waveform, and
the bottom right contains demodulation
metrics with deviation, carrier power, carrier frequency error, SINAD and distortion
results.
Figure 6. FM stereo MPX view/display with RF spectrum, AF spectrum, demod waveform and
demodulation metrics results.
FM stereo mono/stereo/left/
right view
For FM stereo, mono signal (L+R) occupies
the lower part of the baseband spectrum
(50 Hz to 15 kHz) in order to maintain
backward compatibility with the previous
monophonic FM systems. The stereo signal
(L-R) is amplitude modulated onto a suppressed subcarrier at 38 kHz. A pilot signal
is transmitted at 19 kHz and is used by
the receiver to identify a stereo transmission and reconstruct L and R audio signals
from the multiplexed signal. In the receiver,
mono and stereo signals will be demodulated first and then the mono signal (L+R)
is added to the stereo signal (L-R) to get
the L signal, and the stereo signal (L-R) is
subtracted to get the R signal. The mono/
stereo/left/right views will display the
demodulated waveform, AF spectrum
and deviation, SINAD, distortion and THD
results for the selected channel. Figure 7
is an example of FM stereo left channel
demodulation results.

RDS/RBDS decoding results view
The main objectives of FM RDS/RBDS are:
–– To enhance functionality for FM
receivers
–– To make the receivers more userfriendly by using features such as PI
(program identification), PS (program
service) name display, and, if applicable, automatic tuning for portable
and car radios.
RDS/RBDS uses the 57 kHz subcarrier
to carry the data at 1.1875 kbps bitrate.
The 57 kHz subcarrier is chosen to be
the third harmonic of the pilot tone. The
deviation range of the FM carrier due to
the unmodulated RDS/RBDS subcarrier is
1.0 kHz ± 7.5 kHz. Figure 8 is an example
of the RDS/RBDS decoding view showing
the results of the BLER, basic tuning and
switching info, radio text, program item
number and slow labeling codes, clocktime, and date information.
