R&S®DDF255-HRP high-resolution panorama
spectrum
The R&S®DDF255-HRP option supports the R&S®CA120
multichannel signal analysis system with the automatic
detection of fixed
frequency and burst signals within the
R&S®DDF255 realtime bandwidth, thereby enabling au
-
tomatic signal detection/
monitoring and processing (with
R&S®DDF255DDCE). A high-resolution spectrum is calcu
-
lated within the realtime bandwidth, and the spectra are
output on the 1 Gbit Ethernet interface to be further pro
-
cessed by the R&S®CA120DSC option. The option runs on
the
R&S®DDF255-SP signal processing board.
R&S®DDF255-IGT internal GPS module and
external GPS antenna
The internal GPS module's NMEA protocol sets the system
time. The R&S®DDF255 direction finder's internal 10 MHz
reference frequency can be synchronized over the extra
input using the GPS module's PPS signal. This increases
the accuracy of the internal reference to typ.
10
–12
(or bet
-
ter). In addition, the receiver's output data stream is given
a high-precision timestamp. The accuracy of the time
-
stamp is typically in the nanosecond range.
This option can also be used to determine the location of
the direction finder, e.g. in mobile DF applications where
the results are presented on a map.
R&S®DDF255-DDC digital downconverter
The R&S®DDF255-DDC option transforms the
R&S®DDF255 digital direction finder into a multichannel
receiver with a total of five demodulation channels, which
can be allocated to any frequencies within the realtime
bandwidth. The demodulation channels can be parameter
-
ized independently of each other (demodulation mode,
level squelch, etc.). Demodulated data can be stored and
replayed internally, and is also available at the Ethernet
interface.
R&S®DDF255-WB bandwidth extension to 80 MHz
The R&S®DDF255-WB option expands the R&S®DDF255
realtime bandwidth to 80 MHz. This permits the demodu
-
lation (I/Q) of signals up to this bandwidth, improves the
detection of short-time signals and increases the scan
speed to 850 GHz/s (in-band).
The R&S®DDF255-WB option has no impact on the
DF functionality of the R&S®DDF255.
R&S®DDF-10G 10 Gbit Ethernet interface
The R&S®DDF255 is equipped as standard with two 1 Gbit
LAN interfaces. These support the transmission of I/Q
data with a bandwidth of up to 15 MHz. The optional
10 Gbit Ethernet interface supports I/Q data transmission
up to the R&S®DDF255 maximum realtime bandwidth of
80 MHz. No transceiver module is supplied with this op
-
tion, because a transceiver module is included with the
R&S®GX460 digital wideband storage device. Transceiver
modules can be ordered separately if required.
R&S®DDF255-SP signal processing board
When equipped with this hardware-accelerated signal pro
-
cessing option, the R&S®DDF255 supports the R&S®CA120
multichannel signal analysis system. The
R&S®DDF255-SP
signal processing board provides an execution platform for
the R&S®DDF255DDCE and R&S®DDF255-HRP options.
R&S®DDF255DDCE DDC signal extraction
The R&S®DDF255DDCE option uses digital downconver
-
sion (DDC) to extract signals from the R&S®DDF255 real
-
time bandwidth. Depending on the bandwidth set on the
R&S®DDF255 and the desired DDC bandwidth, well over
100 signals can be extracted simultaneously. The option
runs on the R&S®DDF255-SP signal processing board
