ferences, transient emissions etc. can immediately be seen at a glance. The
R&S DDF205
can be switched to "listen" mode simply by pressing a key. The signal
of interest can be selected, demodulated and analyzed by using the demodulation
frequency.
Refer to the operating manual for a detailed explanation.
2.4.2
ITU Measurement (R&S DDF205-IM)
With SW option R&S DDF205-IM (ITU-Measurement) installed, the measurement
functions "AM modulation index", "FM frequency deviation", "PM phase deviation"
and "bandwidth measurement" are available in addition to level and offset mea-
surement.
Refer to the operating manual for a detailed explanation.
2.4.3
HF Frequency Range Extension (R&S DDF205-HF)
This is a hardware option: it requires a HF preselector board to be installed. With
the
HF option installed, signals from 9 kHz to 32 MHz can be obtained (which covers
the full HF range from 3 MHz to 30 MHz).
Refer to the operating manual for a detailed explanation.
2.4.4
SHF Frequency Range Extension (R&S DDF205-FE)
The FE option provides an extended frequency range from 3.6 GHz to 6 GHz.
Refer to the operating manual for a detailed explanation.
2.4.5
Selective Call (R&S DDF205-SL)
The R&S DDF205-SL option can be used to decode selective-call methods and to
demodulate pagers. The following selective-call methods are supported: CCIR1,
CCIR7, CCITT, EEA, EIA, EURO, DCS, DTMF, CTCSS, NATEL, VDEW, ZVEI1,
ZVEI2.
Refer to the operating manual for a detailed explanation.
