2.4 Vector Analyzer Mode
The Vector Signal Analyzer in the FSE allows the analysis of analog and digital modulations. For this
purpose, the FSE samples the IF signal which is band-limited by the resolution bandwidth (RBW ) and
mixes it into the complex baseband. The real and im aginary section of the signal is then digitally filtered
and further processed in digital signal processors. The complex baseband contains the whole signal
information which can be evaluated according to the different criteria.

Three types of analysis are distinguished in the vector signal analyzer:
• In the analog demodulation m ode, the amplitude (AM), frequency (FM) or phase (PM) demodulated
signal is represented as a function of tim e. Alternatively, display of a table containing the numerical
demodulation parameters can be selected
(RESULT DISPLAY)
.
• For digitally modulated signals, the m ost comm only used demodulators are available to evaluate the
modulation parameters.
• In the

mode, the magnitude of the non-demodulated signal c an also be
displayed (MAGNITUDE CAP BUFFER).

2.4.2 Analog Demodulation Methods
With am plitude, frequency and phase demodulation, the FSE pr ovides all demodulation m ethods which
can be used for analog RF carrier m odulation or which may impair a carrier. The bandwidth used for
demodulation depends on the demodulation bandwidth selected. Make sure that the entire modulation
spectrum is included in the demodulation bandwidth. Otherwise, signal distortions that impair the
modulation will be caused by analog prefiltering with the IF filters of the FSE and digital filtering for
suppression of aliasing products due to sampling or data reduction. Correct measurement of the
modulation parameters will no longer be possible.
For correct demodulation make sure that only the signal to be analyzed is located within the
demoduation bandwidth
(DEMOD BANDWIDTH)
impaired by adjacent signals. Spectral com ponents of adjacent signals should be at a distance of at
least 1.285 times the (demodulation bandwidth)/2 from the center frequency (= carrier frequency).

possible.
Real-time and offline demodulation differ as follows:
• Real-time demodulation
♦ The bandwidth of the demodulated signal can be reduced in the AF region using switchable
(REAL TIME ON)
highpass, lowpass or weighting filters (CCITT or C-message filter) to enable spurious modulation
measurements for analog radio systems in line with the standard; moreover, deemphases can also
be switched on for FM (and AM). A deemphasis, if switched on, has an effect on the audio signal
(provided via loudspeaker or headphones connector) and on the result display or on the audio
signal only. The switchable filters, however, always have an effect on the display and
AF/loudspeaker output.
♦The demodulated signal can be monitored via the built-in loudspeaker or via the headphones
output.
♦In addition, the demodulated signal (parts of it) or a summary of numerical modulation parameters
can be displayed on the sceen. With the aid of the split screen display, the demodulated signal and
the summery of numerical modulation parameters can be displayed at the same time.
• Offline demodulation
♦ The demodulation is not carried out continuously, but in blocks, ie a data block is written into the
(REAL TIME OFF)
memory and then demodulated and displayed:
♦The measurement result displayed on the screen is the time function of the demodulated AF signal
and/or a summary of numerical modulation parameters.
♦ The internal loudspeaker, the headphones output is switched off.
♦ No highpass filters and no weighting filters can be activated.
Deemphases cannot be switched on.
♦To restrict the noise bandwidth, AF lowpass filters can be selected, standardized to the
demodulation bandwidth (cutoff frequency = 5, 10 or 25 % of demodulation bandwidth).
The two demodulation modes provided are designed for the following main applications:
• Real-time demodulation (
REAL TIME ON
) for demodulation bandwidths up to max. 200 kHz for
modulation measurements to the standard on analog radio systems and also for monitoring.
• Offline demodulation (
REAL TIME OFF
), especially for measurement of transients (e.g. frequency
settling of oscillators and synthesizers).
The following diagram shows the menus which permit to set the par ameters and the result dis play with
analog demodulation.
